Zolpidem tartrate 12.5 MG Extended Release Oral Tablet

DRUG INTERACTIONS

7 CNS depressants, including alcohol: Possible adverse additive CNS-depressant effects ( 5.1 , 7.1 ) Imipramine: Decreased alertness observed ( 7.1 ) Chlorpromazine: Impaired alertness and psychomotor performance observed ( 7.1 ) CYP3A4 inducers (rifampin or St.

John’s wort): Combination use may decrease effect ( 7.2 ) Ketoconazole: Combination use may increase effect ( 7.2 ) 7.1 CNS-active Drugs Co-administration of zolpidem with other CNS depressants increases the risk of CNS depression.

Concomitant use of zolpidem with these drugs may increase drowsiness and psychomotor impairment, including impaired driving ability [see Warnings and Precautions (5.1) ].

Zolpidem tartrate was evaluated in healthy volunteers in single-dose interaction studies for several CNS drugs.

Imipramine, Chlorpromazine Imipramine in combination with zolpidem produced no pharmacokinetic interaction other than a 20% decrease in peak levels of imipramine, but there was an additive effect of decreased alertness.

Similarly, chlorpromazine in combination with zolpidem produced no pharmacokinetic interaction, but there was an additive effect of decreased alertness and psychomotor performance [see Clinical Pharmacology (12.3) ] .

Haloperidol A study involving haloperidol and zolpidem revealed no effect of haloperidol on the pharmacokinetics or pharmacodynamics of zolpidem.

The lack of a drug interaction following single-dose administration does not predict the absence of an effect following chronic administration [see Clinical Pharmacology (12.3) ] .

Alcohol An additive adverse effect on psychomotor performance between alcohol and oral zolpidem was demonstrated [see Warnings and Precautions (5.1) ].

Sertraline Concomitant administration of zolpidem and sertraline increases exposure to zolpidem [see Clinical Pharmacology (12.3) ] .

Fluoxetine After multiple doses of zolpidem tartrate and fluoxetine an increase in the zolpidem half-life (17%) was observed.

There was no evidence of an additive effect in psychomotor performance [see Clinical Pharmacology (12.3) ] .

7.2 Drugs that Affect Drug Metabolism via Cytochrome P450 Some compounds known to induce or inhibit CYP3A may affect exposure to zolpidem.

The effect of drugs that induce or inhibit other P450 enzymes on the exposure to zolpidem is not known.

CYP3A4 Inducers Rifampin Rifampin, a CYP3A4 inducer, significantly reduced the exposure to and the pharmacodynamic effects of zolpidem.

Use of Rifampin in combination with zolpidem may decrease the efficacy of zolpidem and is not recommended [see Clinical Pharmacology (12.3) ] .

St.

John’s wort Use of St.

John’s wort, a CYP3A4 inducer, in combination with zolpidem may decrease blood levels of zolpidem and is not recommended.

CYP3A4 Inhibitors Ketoconazole Ketoconazole, a potent CYP3A4 inhibitor, increased the exposure to and pharmacodynamic effects of zolpidem.

Consideration should be given to using a lower dose of zolpidem when a potent CYP3A4 inhibitor and zolpidem are given together [see Clinical Pharmacology (12.3) ] .

OVERDOSAGE

10 10.1 Signs and Symptoms In postmarketing experience of overdose with zolpidem tartrate alone, or in combination with CNS-depressant agents, impairment of consciousness ranging from somnolence to coma, cardiovascular and/or respiratory compromise and fatal outcomes have been reported.

10.2 Recommended Treatment General symptomatic and supportive measures should be used along with immediate gastric lavage where appropriate.

Intravenous fluids should be administered as needed.

Zolpidem’s sedative hypnotic effect was shown to be reduced by flumazenil and therefore may be useful; however, flumazenil administration may contribute to the appearance of neurological symptoms (convulsions).

As in all cases of drug overdose, respiration, pulse, blood pressure, and other appropriate signs should be monitored and general supportive measures employed.

Hypotension and CNS depression should be monitored and treated by appropriate medical intervention.

Sedating drugs should be withheld following zolpidem overdosage, even if excitation occurs.

The value of dialysis in the treatment of overdosage has not been determined, although hemodialysis studies in patients with renal failure receiving therapeutic doses have demonstrated that zolpidem is not dialyzable.

As with the management of all overdosage, the possibility of multiple drug ingestion should be considered.

The physician may wish to consider contacting a poison control center for up-to-date information on the management of hypnotic drug product overdosage.

DESCRIPTION

11 AMBIEN CR contains zolpidem tartrate, a gamma-aminobutyric acid (GABA) A agonist of the imidazopyridine class.

AMBIEN CR (zolpidem tartrate extended-release tablets) is available in 6.25 mg and 12.5 mg strength tablets for oral administration.

Chemically, zolpidem is N,N,6-trimethyl-2-p-tolylimidazo[1,2-a] pyridine-3-acetamide L-(+)-tartrate (2:1).

It has the following structure: Zolpidem tartrate is a white to off-white crystalline powder that is sparingly soluble in water, alcohol, and propylene glycol.

It has a molecular weight of 764.88.

AMBIEN CR consists of a coated two-layer tablet: one layer that releases its drug content immediately and another layer that allows a slower release of additional drug content.

The 12.5 mg AMBIEN CR tablet contains the following inactive ingredients: colloidal silicon dioxide, FD&C Blue #2, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polyethylene glycol, potassium bitartrate, sodium starch glycolate, titanium dioxide, and yellow ferric oxide.

Chemical Structure

CLINICAL STUDIES

14 14.1 Controlled Clinical Trials AMBIEN CR was evaluated in three placebo-controlled studies for the treatment of patients with chronic primary insomnia (as defined in the APA Diagnostic and Statistical Manual of Mental Disorders, DSM IV).

Adult outpatients (18–64 years) with primary insomnia (N=212) were evaluated in a double-blind, randomized, parallel-group, 3-week trial comparing AMBIEN CR 12.5 mg and placebo.

AMBIEN CR 12.5 mg decreased wake time after sleep onset (WASO) for the first 7 hours during the first 2 nights and for the first 5 hours after 2 weeks of treatment.

AMBIEN CR 12.5 mg was superior to placebo on objective measures (polysomnography recordings) of sleep induction (by decreasing latency to persistent sleep [LPS]) during the first 2 nights of treatment and after 2 weeks of treatment.

AMBIEN CR 12.5 mg was also superior to placebo on the patient reported global impression regarding the aid to sleep after the first 2 nights and after 3 weeks of treatment.

Elderly outpatients (≥ 65 years) with primary insomnia (N=205) were evaluated in a double-blind, randomized, parallel-group, 3-week trial comparing AMBIEN CR 6.25 mg and placebo.

AMBIEN CR 6.25 mg decreased wake time after sleep onset (WASO) for the first 6 hours during the first 2 nights and the first 4 hours after 2 weeks of treatment.

AMBIEN CR 6.25 mg was superior to placebo on objective measures (polysomnography recordings) of sleep induction (by decreasing LPS) during the first 2 nights of treatment and after 2 weeks on treatment.

AMBIEN CR 6.25 mg was superior to placebo on the patient reported global impression regarding the aid to sleep after the first 2 nights and after 3 weeks of treatment.

In both studies, in patients treated with AMBIEN CR, polysomnography showed increased wakefulness at the end of the night compared to placebo-treated patients.

In a 24-week double-blind, placebo controlled, randomized study in adult outpatients (18–64 years) with primary insomnia (N=1025), AMBIEN CR 12.5 mg administered as needed (3 to 7 nights per week) was superior to placebo over 24 weeks, on patient global impression regarding aid to sleep, and on patient-reported specific sleep parameters for sleep induction and sleep maintenance with no significant increased frequency of drug intake observed over time.

14.2 Studies Pertinent to Safety Concerns for Sedative/Hypnotic Drugs Next-day residual effects: In five clinical studies [three controlled studies in adults (18–64 years of age) administered AMBIEN CR 12.5 mg and two controlled studies in the elderly (≥ 65 years of age) administered AMBIEN CR 6.25 mg or 12.5 mg], the effect of AMBIEN CR on vigilance, memory, or motor function were assessed using neurocognitive tests.

In these studies, no significant decrease in performance was observed eight hours after a nighttime dose.

In addition, no evidence of next-day residual effects was detected with AMBIEN CR 12.5 mg and 6.25 mg using self-ratings of sedation.

During the 3-week studies, next-day somnolence was reported by 15% of the adult patients who received 12.5 mg AMBIEN CR versus 2% of the placebo group; next-day somnolence was reported by 6% of the elderly patients who received 6.25 mg AMBIEN CR versus 5% of the placebo group [see Adverse Reactions (6) ] .

In a 6-month study, the overall incidence of next-day somnolence was 5.7% in the AMBIEN CR group as compared to 2% in the placebo group.

Rebound effects: Rebound insomnia, defined as a dose-dependent worsening in sleep parameters (latency, sleep efficiency, and number of awakenings) compared with baseline following discontinuation of treatment, is observed with short- and intermediate-acting hypnotics.

In the two 3-week placebo-controlled studies in patients with primary insomnia, a rebound effect was only observed on the first night after abrupt discontinuation of AMBIEN CR.

On the second night, there was no worsening compared to baseline in the AMBIEN CR group.

In a 6-month placebo-controlled study in which AMBIEN CR was taken as needed (3 to 7 nights per week), within the first month a rebound effect was observed for Total Sleep Time (not for WASO) during the first night off medication.

After this first month period, no further rebound insomnia was observed.

After final treatment discontinuation no rebound was observed.

GERIATRIC USE

8.5 Geriatric Use A total of 99 elderly (≥ 65 years of age) received daily doses of 6.25 mg AMBIEN CR in a 3-week placebo-controlled study.

The adverse reaction profile of AMBIEN CR 6.25 mg in this population was similar to that of AMBIEN CR 12.5 mg in younger adults (≤ 64 years of age).

Dizziness was reported in 8% of AMBIEN CR-treated patients compared with 3% of those treated with placebo.

The dose of AMBIEN CR in elderly patients is 6.25 mg to minimize adverse effects related to impaired motor and/or cognitive performance and unusual sensitivity to sedative/hypnotic drugs [see Warnings and Precautions (5.1) ] .

MECHANISM OF ACTION

12.1 Mechanism of Action Zolpidem, the active moiety of zolpidem tartrate, is a hypnotic agent with a chemical structure unrelated to benzodiazepines, barbiturates, or other drugs with known hypnotic properties.

It interacts with a GABA-BZ receptor complex and shares some of the pharmacological properties of the benzodiazepines.

In contrast to the benzodiazepines, which non-selectively bind to and activate all BZ receptor subtypes, zolpidem in vitro binds the BZ 1 receptor preferentially with a high affinity ratio of the α 1 /α 5 subunits.

This selective binding of zolpidem on the BZ 1 receptor is not absolute, but it may explain the relative absence of myorelaxant and anticonvulsant effects in animal studies as well as the preservation of deep sleep (stages 3 and 4) in human studies of zolpidem tartrate at hypnotic doses.

INDICATIONS AND USAGE

1 AMBIEN CR (zolpidem tartrate extended-release tablets) is indicated for the treatment of insomnia characterized by difficulties with sleep onset and/or sleep maintenance (as measured by wake time after sleep onset).

The clinical trials performed in support of efficacy were up to 3 weeks (using polysomnography measurement up to 2 weeks in both adult and elderly patients) and 24 weeks (using patient-reported assessment in adult patients only) in duration [see Clinical Studies (14) ] .

PEDIATRIC USE

8.4 Pediatric Use AMBIEN CR is not recommended for use in children.

Safety and effectiveness of zolpidem in pediatric patients below the age of 18 years have not been established.

In an 8-week study in pediatric patients (aged 6–17 years) with insomnia associated with attention-deficit/hyperactivity disorder (ADHD) an oral solution of zolpidem tartrate dosed at 0.25 mg/kg at bedtime did not decrease sleep latency compared to placebo.

Psychiatric and nervous system disorders comprised the most frequent (> 5%) treatment emergent adverse reactions observed with zolpidem versus placebo and included dizziness (23.5% vs.

1.5%), headache (12.5% vs.

9.2%), and hallucinations were reported in 7% of the pediatric patients who received zolpidem; none of the pediatric patients who received placebo reported hallucinations [see Warnings and Precautions (5.4) ] .

Ten patients on zolpidem (7.4%) discontinued treatment due to an adverse reaction.

FDA has not required pediatric studies of AMBIEN CR in the pediatric population based on these efficacy and safety findings.

PREGNANCY

8.1 Pregnancy Pregnancy Category C There are no adequate and well-controlled studies of AMBIEN CR in pregnant women.

Studies in children to assess the effects of prenatal exposure to zolpidem have not been conducted; however, cases of severe neonatal respiratory depression have been reported when zolpidem was used at the end of pregnancy, especially when taken with other CNS depressants.

Children born to mothers taking sedative-hypnotic drugs may be at risk for withdrawal symptoms during the postnatal period.

Neonatal flaccidity has also been reported in infants born to mothers who received sedative-hypnotic drugs during pregnancy.

AMBIEN CR should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus.

Administration of zolpidem to pregnant rats and rabbits resulted in adverse effects on offspring development at doses greater than the AMBIEN CR maximum recommended human dose (MRHD) of 12.5 mg/day (approximately 10 mg/day zolpidem base); however, teratogenicity was not observed.

When zolpidem was administered at oral doses of 4, 20, and 100 mg base/kg/day to pregnant rats during the period of organogenesis, dose-related decreases in fetal skull ossification occurred at all but the lowest dose, which is approximately 4 times the MRHD on a mg/m 2 basis.

In rabbits treated during organogenesis with zolpidem at oral doses of 1, 4, and 16 mg base/kg/day, increased embryo-fetal death and incomplete fetal skeletal ossification occurred at the highest dose.

The no-effect dose for embryo-fetal toxicity in rabbits is approximately 8 times the MRHD on a mg/m 2 basis.

Administration of zolpidem to rats at oral doses of 4, 20, and 100 mg base/kg/day during the latter part of pregnancy and throughout lactation produced decreased offspring growth and survival at all but the lowest dose, which is approximately 4 times the MRHD on a mg/m 2 basis.

NUSRING MOTHERS

8.3 Nursing Mothers Zolpidem is excreted in human milk.

Caution should be exercised when AMBIEN CR is administered to a nursing woman.

WARNING AND CAUTIONS

5 WARNINGS AND PRECAUTIONS CNS depressant effects: Impaired alertness and motor coordination, including risk of morning impairment.

Caution patients against driving and other activities requiring complete mental alertness the morning after use.

( 5.1 ) Need to evaluate for co-morbid diagnoses: Revaluate if insomnia persists after 7 to 10 days of use.

( 5.2 ) Severe anaphylactic/anaphylactoid reactions: Angioedema and anaphylaxis have been reported.

Do not rechallenge if such reactions occur.

( 5.3 ) “Sleep-driving” and other complex behaviors while not fully awake.

Risk increases with dose and use with other CNS depressants and alcohol.

Immediately evaluate any new onset behavioral changes.

( 5.4 ) Depression: Worsening of depression or, suicidal thinking may occur.

Prescribe the least amount of tablets feasible to avoid intentional overdose.

( 5.5 ) Respiratory Depression: Consider this risk before prescribing in patients with compromised respiratory function.

( 5.6 ) Hepatic Impairment: Avoid AMBIEN CR use in patients with severe hepatic impairment.

( 5.7 ) Withdrawal effects: Symptoms may occur with rapid dose reduction or discontinuation.

( 5.8 , 9.3 ) Severe Injuries: Drowsiness may lead to fall including severe injuries.

( 5.9 ) 5.1 CNS Depressant Effects and Next-Day Impairment AMBIEN CR is a central nervous system (CNS) depressant and can impair daytime function in some patients even when used as prescribed.

Prescribers should monitor for excess depressant effects, but impairment can occur in the absence of subjective symptoms, and may not be reliably detected by ordinary clinical exam (i.e.

less than formal psychomotor testing).

While pharmacodynamic tolerance or adaptation to some adverse depressant effects of AMBIEN CR may develop, patients using AMBIEN CR should be cautioned against driving or engaging in other hazardous activities or activities requiring complete mental alertness the day after use.

Additive effects occur with concomitant use of other CNS depressants (e.g.

benzodiazepines, opioids, tricyclic antidepressants, alcohol), including daytime use.

Downward dose adjustment of AMBIEN CR and concomitant CNS depressants should be considered [see Dosage and Administration (2.3) ] .

The use of AMBIEN CR with other sedative-hypnotics (including other zolpidem products) at bedtime or the middle of the night is not recommended.

The risk of next-day psychomotor impairment is increased if AMBIEN CR is taken with less than a full night of sleep remaining (7 to 8 hours); if higher than the recommended dose is taken; if co-administered with other CNS depressants or alcohol; or co-administered with other drugs that increase the blood levels of zolpidem.

Patients should be warned against driving and other activities requiring complete mental alertness if Ambien CR is taken in these circumstances [see Dosage and Administration (2) and Clinical Studies (14.2) ] .

Vehicle drivers and machine operators should be warned that, as with other hypnotics, there may be a possible risk of adverse reactions including drowsiness, prolonged reaction time, dizziness, sleepiness, blurred/double vision, reduced alertness and impaired driving the morning after therapy.

In order to minimize this risk a full night of sleep (7-8 hours) is recommended.

5.2 Need to Evaluate for Co-morbid Diagnoses Because sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient.

The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated.

Worsening of insomnia or the emergence of new thinking or behavior abnormalities may be the consequence of an unrecognized psychiatric or physical disorder.

Such findings have emerged during the course of treatment with sedative/hypnotic drugs, including zolpidem.

5.3 Severe Anaphylactic and Anaphylactoid Reactions Cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of sedative-hypnotics, including zolpidem.

Some patients have had additional symptoms such as dyspnea, throat closing or nausea and vomiting that suggest anaphylaxis.

Some patients have required medical therapy in the emergency department.

If angioedema involves the throat, glottis or larynx, airway obstruction may occur and be fatal.

Patients who develop angioedema after treatment with zolpidem should not be rechallenged with the drug.

5.4 Abnormal Thinking and Behavioral Changes Abnormal thinking and behavior changes have been reported in patients treated with sedative/hypnotics, including AMBIEN CR.

Some of these changes included decreased inhibition (e.g.

aggressiveness and extroversion that seemed out of character), bizarre behavior, agitation and depersonalization.

Visual and auditory hallucinations have been reported.

In controlled trials, <1% of adults with insomnia reported hallucinations.

In a clinical trial, 7% of pediatric patients treated with AMBIEN 0.25 mg/kg taken at bedtime reported hallucinations versus 0% treated with placebo [see Use in Specific Populations (8.4) ] .

Complex behaviors such as “sleep-driving” (i.e., driving while not fully awake after ingestion of a sedative-hypnotic, with amnesia for the event) have been reported in sedative-hypnotic-naive as well as in sedative-hypnotic-experienced persons.

Although behaviors such as “sleep-driving” have occurred with AMBIEN CR alone at therapeutic doses, the co-administration of alcohol and other CNS depressants increases the risk of such behaviors, as does the use of AMBIEN CR at doses exceeding the maximum recommended dose.

Due to the risk to the patient and the community, discontinuation of AMBIEN CR should be strongly considered for patients who report a “sleep-driving” episode.

Other complex behaviors (e.g., preparing and eating food, making phone calls, or having sex) have been reported in patients who are not fully awake after taking a sedative-hypnotic.

As with “sleep-driving”, patients usually do not remember these events.

Amnesia, anxiety and other neuro-psychiatric symptoms may also occur.

It can rarely be determined with certainty whether a particular instance of the abnormal behaviors listed above is drug induced, spontaneous in origin, or a result of an underlying psychiatric or physical disorder.

Nonetheless, the emergence of any new behavioral sign or symptom of concern requires careful and immediate evaluation.

5.5 Use in Patients with Depression In primarily depressed patients treated with sedative-hypnotics, worsening of depression, and suicidal thoughts and actions (including completed suicides), have been reported.

Suicidal tendencies may be present in such patients and protective measures may be required.

Intentional overdosage is more common in this group of patients; therefore, the lowest number of tablets that is feasible should be prescribed for the patient at any one time.

5.6 Respiratory Depression Although studies with 10 mg zolpidem tartrate did not reveal respiratory depressant effects at hypnotic doses in healthy subjects or in patients with mild-to-moderate chronic obstructive pulmonary disease (COPD), a reduction in the Total Arousal Index, together with a reduction in lowest oxygen saturation and increase in the times of oxygen desaturation below 80% and 90%, was observed in patients with mild-to-moderate sleep apnea when treated with zolpidem compared to placebo.

Since sedative-hypnotics have the capacity to depress respiratory drive, precautions should be taken if AMBIEN CR is prescribed to patients with compromised respiratory function.

Post-marketing reports of respiratory insufficiency in patients receiving 10 mg of zolpidem tartrate, most of whom had pre-existing respiratory impairment, have been reported.

The risk of respiratory depression should be considered prior to prescribing AMBIEN CR in patients with respiratory impairment including sleep apnea and myasthenia gravis.

5.7 Precipitation of Hepatic Encephalopathy GABA agonists such as zolpidem tartrate have been associated with precipitation of hepatic encephalopathy in patients with hepatic insufficiency.

In addition, patients with hepatic insufficiency do not clear zolpidem tartrate as rapidly as patients with normal hepatic function.

Avoid AMBIEN CR use in patients with severe hepatic impairment as it may contribute to encephalopathy [see Dosage and Administration (2.2) , Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ] .

5.8 Withdrawal Effects There have been reports of withdrawal signs and symptoms following the rapid dose decrease or abrupt discontinuation of zolpidem.

Monitor patients for tolerance, abuse, and dependence [see Drug Abuse and Dependence (9.2) and (9.3) ] .

5.9 Severe Injuries Zolpidem can cause drowsiness and a decreased level of consciousness, which may lead to falls and consequently to severe injuries.

Severe injuries such as hip fractures and intracranial hemorrhage have been reported.

INFORMATION FOR PATIENTS

17 PATIENT COUNSELING INFORMATION Advise patients to read the FDA-approved patient labeling (Medication Guide).

Inform patients and their families about the benefits and risks of treatment with AMBIEN CR.

Inform patients of the availability of a Medication Guide and instruct them to read the Medication Guide prior to initiating treatment with AMBIEN CR and with each prescription refill.

Review the AMBIEN CR Medication Guide with every patient prior to initiation of treatment.

Instruct patients or caregivers that AMBIEN CR should be taken only as prescribed.

CNS Depressant Effects and Next-Day Impairment Tell patients that AMBIEN CR can cause next-day impairment even when used as prescribed, and that this risk is increased if dosing instructions are not carefully followed.

Caution patients against driving and other activities requiring complete mental alertness the day after use.

Inform patients that impairment can be present despite feeling fully awake.

Severe Anaphylactic and Anaphylactoid Reactions Inform patients that severe anaphylactic and anaphylactoid reactions have occurred with zolpidem.

Describe the signs/symptoms of these reactions and advise patients to seek medical attention immediately if any of them occur.

Sleep-driving and Other Complex Behaviors Instruct patients and their families that sedative hypnotics can cause abnormal thinking and behavior change, including “sleep driving” and other complex behaviors while not being fully awake (preparing and eating food, making phone calls, or having sex).

Tell patients to call you immediately if they develop any of these symptoms.

Suicide Tell patients to immediately report any suicidal thoughts.

Alcohol and Other Drugs Ask patients about alcohol consumption, medicines they are taking, and drugs they may be taking without a prescription.

Advise patients not to use AMBIEN CR if they drank alcohol that evening or before bed.

Tolerance, Abuse, and Dependence Tell patients not to increase the dose of AMBIEN CR on their own, and to inform you if they believe the drug “does not work”.

Administration Instructions Patients should be counseled to take AMBIEN CR right before they get into bed and only when they are able to stay in bed a full night (7–8 hours) before being active again.

AMBIEN CR tablets should not be taken with or immediately after a meal.

Advise patients NOT to take AMBIEN CR if they drank alcohol that evening.

DOSAGE AND ADMINISTRATION

2 Use the lowest dose effective for the patient and must not exceed a total of 12.5 mg daily ( 2.1 ) Recommended initial dose is a single dose of 6.25 mg for women, and a single dose of 6.25 or 12.5 mg for men, immediately before bedtime with at least 7–8 hours remaining before the planned time of awakening ( 2.1 ) Geriatric patients and patients with mild to moderate hepatic impairment: Recommended dose is 6.25 mg for men and women ( 2.2 ) Lower doses of CNS depressants may be necessary when taken concomitantly with AMBIEN CR ( 2.3 ) Tablets to be swallowed whole, not to be crushed, divided or chewed ( 2.4 ) The effect of AMBIEN CR may be slowed if taken with or immediately after a meal ( 2.4 ) 2.1 Dosage in Adults Use the lowest effective dose for the patient.

The recommended initial dose is 6.25 mg for women and either 6.25 or 12.5 mg for men, taken only once per night immediately before bedtime with at least 7–8 hours remaining before the planned time of awakening.

If the 6.25 mg dose is not effective, the dose can be increased to 12.5 mg.

In some patients, the higher morning blood levels following use of the 12.5 mg dose increase the risk of next day impairment of driving and other activities that require full alertness [see Warnings and Precautions (5.1) ] .

The total dose of AMBIEN CR should not exceed 12.5 mg once daily immediately before bedtime.

Ambien CR should be taken as a single dose and should not be readministered during the same night.

The recommended initial doses for women and men are different because zolpidem clearance is lower in women.

2.2 Special Populations Elderly or debilitated patients may be especially sensitive to the effects of zolpidem tartrate.

The recommended dose of AMBIEN CR in these patients is 6.25 mg once daily immediately before bedtime [see Warnings and Precautions (5.1) , Use in Specific Populations (8.5) ].

Patients with mild to moderate hepatic impairment do not clear the drug as rapidly as normal subjects.

The recommended dose of AMBIEN CR in these patients is 6.25 mg once daily immediately before bedtime.

Avoid AMBIEN CR use in patients with severe hepatic impairment as it may contribute to encephalopathy [see Warnings and Precautions (5.7) , Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ] .

2.3 Use with CNS Depressants Dosage adjustment may be necessary when AMBIEN CR is combined with other CNS depressant drugs because of the potentially additive effects [see Warnings and Precautions (5.1) ] .

2.4 Administration AMBIEN CR extended-release tablets should be swallowed whole, and not be divided, crushed, or chewed.

The effect of AMBIEN CR may be slowed by ingestion with or immediately after a meal.

DRUG INTERACTIONS

7 The risks of using olanzapine in combination with other drugs have not been extensively evaluated in systematic studies.

Diazepam: May potentiate orthostatic hypotension.

( 7.1 , 7.2 ) Alcohol: May potentiate orthostatic hypotension.

( 7.1 ) Carbamazepine: Increased clearance of olanzapine.

( 7.1 ) Fluvoxamine: May increase olanzapine levels.

( 7.1 ) Olanzapine and Fluoxetine in Combination: Also refer to the Drug Interactions section of the package insert for Symbyax.

( 7.1 ) CNS Acting Drugs: Caution should be used when taken in combination with other centrally acting drugs and alcohol.

( 7.2 ) Antihypertensive Agents: Enhanced antihypertensive effect.

( 7.2 ) Levodopa and Dopamine Agonists: May antagonize levodopa/dopamine agonists.

( 7.2 ) Other Concomitant Drug Therapy: When using olanzapine in combination with lithium or valproate, refer to the Drug Interactions sections of the package insert for those products.

( 7.2 ) 7.1 Potential for Other Drugs to Affect Olanzapine Diazepam — The co-administration of diazepam with olanzapine potentiated the orthostatic hypotension observed with olanzapine [ see Drug Interactions (7.2) ] .

Cimetidine and Antacids — Single doses of cimetidine (800 mg) or aluminum- and magnesium-containing antacids did not affect the oral bioavailability of olanzapine.

Inducers of CYP1A2 — Carbamazepine therapy (200 mg bid) causes an approximately 50% increase in the clearance of olanzapine.

This increase is likely due to the fact that carbamazepine is a potent inducer of CYP1A2 activity.

Higher daily doses of carbamazepine may cause an even greater increase in olanzapine clearance.

Alcohol — Ethanol (45 mg/70 kg single dose) did not have an effect on olanzapine pharmacokinetics.

The co-administration of alcohol (i.e., ethanol) with olanzapine potentiated the orthostatic hypotension observed with olanzapine [see Drug Interactions (7.2)].

Inhibitors of CYP1A2 Fluvoxamine: Fluvoxamine, a CYP1A2 inhibitor, decreases the clearance of olanzapine.

This results in a mean increase in olanzapine C max following fluvoxamine of 54% in female nonsmokers and 77% in male smokers.

The mean increase in olanzapine AUC is 52% and 108%, respectively.

Lower doses of olanzapine should be considered in patients receiving concomitant treatment with fluvoxamine.

Inhibitors of CYP2D6 Fluoxetine: Fluoxetine (60 mg single dose or 60 mg daily dose for 8 days) causes a small (mean 16%) increase in the maximum concentration of olanzapine and a small (mean 16%) decrease in olanzapine clearance.

The magnitude of the impact of this factor is small in comparison to the overall variability between individuals, and therefore dose modification is not routinely recommended.

When using olanzapine and fluoxetine in combination, also refer to the Drug Interactions section of the package insert for Symbyax.

Warfarin — Warfarin (20 mg single dose) did not affect olanzapine pharmacokinetics [ see Drug Interactions (7.2) ] .

Inducers of CYP1A2 or Glucuronyl Transferase — Omeprazole and rifampin may cause an increase in olanzapine clearance.

Charcoal — The administration of activated charcoal (1 g) reduced the C max and AUC of oral olanzapine by about 60%.

As peak olanzapine levels are not typically obtained until about 6 hours after dosing, charcoal may be a useful treatment for olanzapine overdose.

Anticholinergic Drugs — Concomitant treatment with olanzapine and other drugs with anticholinergic activity can increase the risk for severe gastrointestinal adverse reactions related to hypomotility.

Olanzapine should be used with caution in patients receiving medications having anticholinergic (antimuscarinic) effects [see Warnings and Precautions (5.14)] .

7.2 Potential for Olanzapine to Affect Other Drugs CNS Acting Drugs — Given the primary CNS effects of olanzapine, caution should be used when olanzapine is taken in combination with other centrally acting drugs and alcohol.

Antihypertensive Agents — Olanzapine, because of its potential for inducing hypotension, may enhance the effects of certain antihypertensive agents.

Levodopa and Dopamine Agonists — Olanzapine may antagonize the effects of levodopa and dopamine agonists.

Lithium — Multiple doses of olanzapine (10 mg for 8 days) did not influence the kinetics of lithium.

Therefore, concomitant olanzapine administration does not require dosage adjustment of lithium [see Warnings and Precautions (5.16)] .

Valproate — Olanzapine (10 mg daily for 2 weeks) did not affect the steady state plasma concentrations of valproate.

Therefore, concomitant olanzapine administration does not require dosage adjustment of valproate [see Warnings and Precautions (5.16)].

Effect of Olanzapine on Drug Metabolizing Enzymes — In vitro studies utilizing human liver microsomes suggest that olanzapine has little potential to inhibit CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A.

Thus, olanzapine is unlikely to cause clinically important drug interactions mediated by these enzymes.

Imipramine — Single doses of olanzapine did not affect the pharmacokinetics of imipramine or its active metabolite desipramine.

Warfarin — Single doses of olanzapine did not affect the pharmacokinetics of warfarin [see Drug Interactions (7.1)] .

Diazepam — Olanzapine did not influence the pharmacokinetics of diazepam or its active metabolite N-desmethyldiazepam.

However, diazepam co-administered with olanzapine increased the orthostatic hypotension observed with either drug given alone [see Drug Interactions (7.1)] .

Alcohol — Multiple doses of olanzapine did not influence the kinetics of ethanol [see Drug Interactions (7.1)] .

Biperiden — Multiple doses of olanzapine did not influence the kinetics of biperiden.

Theophylline — Multiple doses of olanzapine did not affect the pharmacokinetics of theophylline or its metabolites.

OVERDOSAGE

10 10.1 Human Experience In premarketing trials involving more than 3100 patients and/or normal subjects, accidental or intentional acute overdosage of olanzapine was identified in 67 patients.

In the patient taking the largest identified amount, 300 mg, the only symptoms reported were drowsiness and slurred speech.

In the limited number of patients who were evaluated in hospitals, including the patient taking 300 mg, there were no observations indicating an adverse change in laboratory analytes or ECG.

Vital signs were usually within normal limits following overdoses.

In postmarketing reports of overdose with olanzapine alone, symptoms have been reported in the majority of cases.

In symptomatic patients, symptoms with ≥10% incidence included agitation/aggressiveness, dysarthria, tachycardia, various extrapyramidal symptoms, and reduced level of consciousness ranging from sedation to coma.

Among less commonly reported symptoms were the following potentially medically serious reactions: aspiration, cardiopulmonary arrest, cardiac arrhythmias (such as supraventricular tachycardia and 1 patient experiencing sinus pause with spontaneous resumption of normal rhythm), delirium, possible neuroleptic malignant syndrome, respiratory depression/arrest, convulsion, hypertension, and hypotension.

Reports of fatality in association with overdose of olanzapine alone have been received.

In 1 case of death, the amount of acutely ingested olanzapine was reported to be possibly as low as 450 mg of oral olanzapine; however, in another case, a patient was reported to survive an acute olanzapine ingestion of approximately 2 g of oral olanzapine.

10.2 Management of Overdose There is no specific antidote to an overdose of olanzapine.

The possibility of multiple drug involvement should be considered.

Establish and maintain an airway and ensure adequate oxygenation and ventilation.

Cardiovascular monitoring should commence immediately and should include continuous electrocardiographic monitoring to detect possible arrhythmias.

Contact a Certified Poison Control Center for the most up to date information on the management of overdosage (1-800-222-1222).

CLINICAL STUDIES

14 When using olanzapine and fluoxetine in combination, also refer to the Clinical Studies section of the package insert for Symbyax.

14.1 Schizophrenia Adults The efficacy of oral olanzapine in the treatment of schizophrenia was established in 2 short-term (6-week) controlled trials of adult inpatients who met DSM III-R criteria for schizophrenia.

A single haloperidol arm was included as a comparative treatment in 1 of the 2 trials, but this trial did not compare these 2 drugs on the full range of clinically relevant doses for both.

Several instruments were used for assessing psychiatric signs and symptoms in these studies, among them the Brief Psychiatric Rating Scale (BPRS), a multi-item inventory of general psychopathology traditionally used to evaluate the effects of drug treatment in schizophrenia.

The BPRS psychosis cluster (conceptual disorganization, hallucinatory behavior, suspiciousness, and unusual thought content) is considered a particularly useful subset for assessing actively psychotic schizophrenic patients.

A second traditional assessment, the Clinical Global Impression (CGI), reflects the impression of a skilled observer, fully familiar with the manifestations of schizophrenia, about the overall clinical state of the patient.

In addition, 2 more recently developed scales were employed; these included the 30-item Positive and Negative Symptoms Scale (PANSS), in which are embedded the 18 items of the BPRS, and the Scale for Assessing Negative Symptoms (SANS).

The trial summaries below focus on the following outcomes: PANSS total and/or BPRS total; BPRS psychosis cluster; PANSS negative subscale or SANS; and CGI Severity.

The results of the trials follow: (1) In a 6-week, placebo-controlled trial (n=149) involving 2 fixed olanzapine doses of 1 and 10 mg/day (once daily schedule), olanzapine, at 10 mg/day (but not at 1 mg/day), was superior to placebo on the PANSS total score (also on the extracted BPRS total), on the BPRS psychosis cluster, on the PANSS Negative subscale, and on CGI Severity.

(2) In a 6-week, placebo-controlled trial (n=253) involving 3 fixed dose ranges of olanzapine (5 ± 2.5 mg/day, 10 ± 2.5 mg/day, and 15 ± 2.5 mg/day) on a once daily schedule, the 2 highest olanzapine dose groups (actual mean doses of 12 and 16 mg/day, respectively) were superior to placebo on BPRS total score, BPRS psychosis cluster, and CGI severity score; the highest olanzapine dose group was superior to placebo on the SANS.

There was no clear advantage for the high-dose group over the medium-dose group.

(3) In a longer-term trial, adult outpatients (n=326) who predominantly met DSM-IV criteria for schizophrenia and who remained stable on olanzapine during open-label treatment for at least 8 weeks were randomized to continuation on their current olanzapine doses (ranging from 10 to 20 mg/day) or to placebo.

The follow-up period to observe patients for relapse, defined in terms of increases in BPRS positive symptoms or hospitalization, was planned for 12 months, however, criteria were met for stopping the trial early due to an excess of placebo relapses compared to olanzapine relapses, and olanzapine was superior to placebo on time to relapse, the primary outcome for this study.

Thus, olanzapine was more effective than placebo at maintaining efficacy in patients stabilized for approximately 8 weeks and followed for an observation period of up to 8 months.

Examination of population subsets (race and gender) did not reveal any differential responsiveness on the basis of these subgroupings.

Adolescents The efficacy of oral olanzapine in the acute treatment of schizophrenia in adolescents (ages 13 to 17 years) was established in a 6-week double-blind, placebo-controlled, randomized trial of inpatients and outpatients with schizophrenia (n=107) who met diagnostic criteria according to DSM-IV-TR and confirmed by the Kiddie Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime Version (K-SADS-PL).

The primary rating instrument used for assessing psychiatric signs and symptoms in this trial was the Anchored Version of the Brief Psychiatric Rating Scale for Children (BPRS-C) total score.

In this flexible-dose trial, olanzapine 2.5 to 20 mg/day (mean modal dose 12.5 mg/day, mean dose of 11.1 mg/day) was more effective than placebo in the treatment of adolescents diagnosed with schizophrenia, as supported by the statistically significantly greater mean reduction in BPRS-C total score for patients in the olanzapine treatment group than in the placebo group.

While there is no body of evidence available to answer the question of how long the adolescent patient treated with olanzapine should be maintained, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients.

It is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission.

Patients should be periodically reassessed to determine the need for maintenance treatment.

14.2 Bipolar I Disorder (Manic or Mixed Episodes) Adults Monotherapy — The efficacy of oral olanzapine in the treatment of manic or mixed episodes was established in 2 short-term (one 3-week and one 4-week) placebo-controlled trials in adult patients who met the DSM-IV criteria for bipolar I disorder with manic or mixed episodes.

These trials included patients with or without psychotic features and with or without a rapid-cycling course.

The primary rating instrument used for assessing manic symptoms in these trials was the Young Mania Rating Scale (Y-MRS), an 11-item clinician-rated scale traditionally used to assess the degree of manic symptomatology (irritability, disruptive/aggressive behavior, sleep, elevated mood, speech, increased activity, sexual interest, language/thought disorder, thought content, appearance, and insight) in a range from 0 (no manic features) to 60 (maximum score).

The primary outcome in these trials was change from baseline in the Y-MRS total score.

The results of the trials follow: (1) In one 3-week placebo-controlled trial (n=67) which involved a dose range of olanzapine (5 to 20 mg/day, once daily, starting at 10 mg/day), olanzapine was superior to placebo in the reduction of Y-MRS total score.

In an identically designed trial conducted simultaneously with the first trial, olanzapine demonstrated a similar treatment difference, but possibly due to sample size and site variability, was not shown to be superior to placebo on this outcome.

(2) In a 4-week placebo-controlled trial (n=115) which involved a dose range of olanzapine (5 to 20 mg/day, once daily, starting at 15 mg/day), olanzapine was superior to placebo in the reduction of Y-MRS total score.

(3) In another trial, 361 patients meeting DSM-IV criteria for a manic or mixed episode of bipolar I disorder who had responded during an initial open-label treatment phase for about 2 weeks, on average, to olanzapine 5 to 20 mg/day were randomized to either continuation of olanzapine at their same dose (n=225) or to placebo (n=136), for observation of relapse.

Approximately 50% of the patients had discontinued from the olanzapine group by day 59 and 50% of the placebo group had discontinued by day 23 of double-blind treatment.

Response during the open-label phase was defined by having a decrease of the Y-MRS total score to ≤12 and HAM-D 21 to ≤8.

Relapse during the double-blind phase was defined as an increase of the Y-MRS or HAM-D 21 total score to ≥15, or being hospitalized for either mania or depression.

In the randomized phase, patients receiving continued olanzapine experienced a significantly longer time to relapse.

Adjunct to Lithium or Valproate — The efficacy of oral olanzapine with concomitant lithium or valproate in the treatment of manic or mixed episodes was established in 2 controlled trials in patients who met the DSM-IV criteria for bipolar I disorder with manic or mixed episodes.

These trials included patients with or without psychotic features and with or without a rapid-cycling course.

The results of the trials follow: (1) In one 6-week placebo-controlled combination trial, 175 outpatients on lithium or valproate therapy with inadequately controlled manic or mixed symptoms (Y-MRS ≥16) were randomized to receive either olanzapine or placebo, in combination with their original therapy.

Olanzapine (in a dose range of 5 to 20 mg/day, once daily, starting at 10 mg/day) combined with lithium or valproate (in a therapeutic range of 0.6 mEq/L to 1.2 mEq/L or 50 mcg/mL to 125 mcg/mL, respectively) was superior to lithium or valproate alone in the reduction of Y-MRS total score.

(2) In a second 6-week placebo-controlled combination trial, 169 outpatients on lithium or valproate therapy with inadequately controlled manic or mixed symptoms (Y-MRS ≥16) were randomized to receive either olanzapine or placebo, in combination with their original therapy.

Olanzapine (in a dose range of 5 to 20 mg/day, once daily, starting at 10 mg/day) combined with lithium or valproate (in a therapeutic range of 0.6 mEq/L to 1.2 mEq/L or 50 mcg/mL to 125 mcg/mL, respectively) was superior to lithium or valproate alone in the reduction of Y-MRS total score.

Adolescents Acute Monotherapy — The efficacy of oral olanzapine in the treatment of acute manic or mixed episodes in adolescents (ages 13 to 17 years) was established in a 3-week, double-blind, placebo-controlled, randomized trial of adolescent inpatients and outpatients who met the diagnostic criteria for manic or mixed episodes associated with bipolar I disorder (with or without psychotic features) according to the DSM-IV-TR (n=161).

Diagnosis was confirmed by the K-SADS-PL.

The primary rating instrument used for assessing manic symptoms in this trial was the Adolescent Structured Young-Mania Rating Scale (Y-MRS) total score.

In this flexible-dose trial, olanzapine 2.5 to 20 mg/day (mean modal dose 10.7 mg/day, mean dose of 8.9 mg/day) was more effective than placebo in the treatment of adolescents with manic or mixed episodes associated with bipolar I disorder, as supported by the statistically significantly greater mean reduction in Y-MRS total score for patients in the olanzapine treatment group than in the placebo group.

While there is no body of evidence available to answer the question of how long the adolescent patient treated with olanzapine should be maintained, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients.

It is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission.

Patients should be periodically reassessed to determine the need for maintenance treatment.

GERIATRIC USE

8.5 Geriatric Use Of the 2500 patients in premarketing clinical studies with oral olanzapine, 11% (263) were 65 years of age or over.

In patients with schizophrenia, there was no indication of any different tolerability of olanzapine in the elderly compared to younger patients.

Studies in elderly patients with dementia-related psychosis have suggested that there may be a different tolerability profile in this population compared to younger patients with schizophrenia.

Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo.

In placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis, there was a higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) in patients treated with olanzapine compared to patients treated with placebo.

In 5 placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis (n=1184), the following adverse reactions were reported in olanzapine-treated patients at an incidence of at least 2% and significantly greater than placebo-treated patients: falls, somnolence, peripheral edema, abnormal gait, urinary incontinence, lethargy, increased weight, asthenia, pyrexia, pneumonia, dry mouth and visual hallucinations.

The rate of discontinuation due to adverse reactions was greater with olanzapine than placebo (13% vs 7%).

Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo.

Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.1), and Patient Counseling Information (17)].

Olanzapine is not approved for the treatment of patients with dementia-related psychosis.

Also, the presence of factors that might decrease pharmacokinetic clearance or increase the pharmacodynamic response to olanzapine should lead to consideration of a lower starting dose for any geriatric patient [see Boxed Warning, Dosage and Administration (2.1), and Warnings and Precautions (5.1)] .

Clinical studies of olanzapine and fluoxetine in combination did not include sufficient numbers of patients ≥65 years of age to determine whether they respond differently from younger patients.

For pediatric schizophrenia, symptom profiles can be variable, and for bipolar I disorder, pediatric patients may have variable patterns of periodicity of manic or mixed symptoms.

It is recommended that medication therapy for pediatric schizophrenia and bipolar I disorder be initiated only after a thorough diagnostic evaluation has been performed and careful consideration given to the risks associated with medication treatment.

Medication treatment for both pediatric schizophrenia and bipolar I disorder should be part of a total treatment program that often includes psychological, educational and social interventions.

Olanzapine orally disintegrating tablets monotherapy is not indicated for the treatment of treatment resistant depression.

PEDIATRIC USE

8.4 Pediatric Use The safety and effectiveness of oral olanzapine in the treatment of schizophrenia and manic or mixed episodes associated with bipolar I disorder were established in short-term studies in adolescents (ages 13 to 17 years).

Use of olanzapine in adolescents is supported by evidence from adequate and well-controlled studies of olanzapine in which 268 adolescents received olanzapine in a range of 2.5 to 20 mg/day [see Clinical Studies (14.1, 14.2)].

Recommended starting dose for adolescents is lower than that for adults [see Dosage and Administration (2.1, 2.2)] .

Compared to patients from adult clinical trials, adolescents were likely to gain more weight, experience increased sedation, and have greater increases in total cholesterol, triglycerides, LDL cholesterol, prolactin and hepatic aminotransferase levels [see Warnings and Precautions (5.5, 5.15, 5.17) and Adverse Reactions (6.1)] .

When deciding among the alternative treatments available for adolescents, clinicians should consider the increased potential (in adolescents as compared with adults) for weight gain and dyslipidemia.

Clinicians should consider the potential long-term risks when prescribing to adolescents, and in many cases this may lead them to consider prescribing other drugs first in adolescents [see Indications and Usage (1.1, 1.2)] .

Safety and effectiveness of olanzapine in children <13 years of age have not been established [see Patient Counseling Information (17)] .

Safety and efficacy of olanzapine and fluoxetine in combination in children and adolescents (10 to 17 years of age) have been established for the acute treatment of depressive episodes associated with bipolar I disorder.

Safety and effectiveness of olanzapine and fluoxetine in combination in children < 10 years of age have not been established.

PREGNANCY

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including olanzapine, during pregnancy.

Healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.

Risk Summary Neonates exposed to antipsychotic drugs, including olanzapine, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see Clinical Considerations).

Overall available data from published epidemiologic studies of pregnant women exposed to olanzapine have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data).

There are risks to the mother associated with untreated schizophrenia or bipolar I disorder and with exposure to antipsychotics, including olanzapine, during pregnancy (see Clinical Considerations).

Olanzapine was not teratogenic when administered orally to pregnant rats and rabbits at doses that are 9- and 30-times the daily oral maximum recommended human dose (MRHD), based on mg/m 2 body surface area; some fetal toxicities were observed at these doses ( see Data ).

The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown.

All pregnancies have a background risk of birth defects, loss, or other adverse outcomes.

In the U.S.

general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Clinical Considerations Disease-associated maternal and embryo/fetal risk There is a risk to the mother from untreated schizophrenia or bipolar I disorder, including increased risk of relapse, hospitalization, and suicide.

Schizophrenia and bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth.

It is not known if this is a direct result of the illness or other comorbid factors.

Fetal/Neonatal adverse reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including olanzapine, during the third trimester of pregnancy.

These symptoms have varied in severity.

Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately.

Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization.

Data Human Data Placental passage has been reported in published study reports; however, the placental passage ratio was highly variable ranging between 7% to 167% at birth following exposure during pregnancy.

The clinical relevance of this finding is unknown.

Published data from observational studies, birth registries, and case reports that have evaluated the use of atypical antipsychotics during pregnancy do not establish an increased risk of major birth defects.

A retrospective cohort study from a Medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk for major birth defects.

Animal Data In oral reproduction studies in rats at doses up to 18 mg/kg/day and in rabbits at doses up to 30 mg/kg/day (9 and 30 times the daily oral MRHD based on mg/m 2 body surface area, respectively), no evidence of teratogenicity was observed.

In an oral rat teratology study, early resorptions and increased numbers of nonviable fetuses were observed at a dose of 18 mg/kg/day (9 times the daily oral MRHD based on mg/m 2 body surface area), and gestation was prolonged at 10 mg/kg/day (5 times the daily oral MRHD based on mg/m 2 body surface area).

In an oral rabbit teratology study, fetal toxicity manifested as increased resorptions and decreased fetal weight, occurred at a maternally toxic dose of 30 mg/kg/day (30 times the daily oral MRHD based on mg/m 2 body surface area).

BOXED WARNING

WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients.

Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group.

Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature.

Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality.

The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear .

Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Warnings and Precautions (5.1) , Use in Specific Populations (8.5 ), and Patient Counseling Information (17) ] .

When using olanzapine and fluoxetine in combination, also refer to the Boxed Warning section of the package insert for Symbyax.

( 5.1 7) 5.1 Elderly Patients with Dementia-Related Psychosis Increased Mortality — Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Use in Specific Populations (8.5) , and Patient Counseling Information (17)] .

In placebo-controlled clinical trials of elderly patients with dementia-related psychosis, the incidence of death in olanzapine-treated patients was significantly greater than placebo-treated patients (3.5% vs 1.5%, respectively).

Cerebrovascular Adverse Events (CVAE), Including Stroke — Cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, were reported in patients in trials of olanzapine in elderly patients with dementia-related psychosis.

In placebo-controlled trials, there was a significantly higher incidence of cerebrovascular adverse events in patients treated with olanzapine compared to patients treated with placebo.

Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning and Patient Counseling Information (17 )] .

5.2 Suicide The possibility of a suicide attempt is inherent in schizophrenia and in bipolar I disorder, and close supervision of high-risk patients should accompany drug therapy.

Prescriptions for olanzapine should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce the risk of overdose.

5.3 Neuroleptic Malignant Syndrome (NMS) A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with administration of antipsychotic drugs, including olanzapine.

Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac dysrhythmia).

Additional signs may include elevated creatinine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.

The diagnostic evaluation of patients with this syndrome is complicated.

In arriving at a diagnosis, it is important to exclude cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS).

Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system pathology.

The management of NMS should include: 1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy; 2) intensive symptomatic treatment and medical monitoring; and 3) treatment of any concomitant serious medical problems for which specific treatments are available.

There is no general agreement about specific pharmacological treatment regimens for NMS.

If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered.

The patient should be carefully monitored, since recurrences of NMS have been reported [see Patient Counseling Information (17) ] .

5.4 Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported with olanzapine exposure.

DRESS may present with a cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, fever, and/or lymphadenopathy with systemic complications such as hepatitis, nephritis, pneumonitis, myocarditis, and/or pericarditis.

DRESS is sometimes fatal.

Discontinue olanzapine if DRESS is suspected [ see Patient Counseling Information (17 )] .

5.5 Metabolic Changes Atypical antipsychotic drugs have been associated with metabolic changes including hyperglycemia, dyslipidemia, and weight gain.

Metabolic changes may be associated with increased cardiovascular/cerebrovascular risk.

Olanzapine’s specific metabolic profile is presented below.

Hyperglycemia and Diabetes Mellitus Healthcare providers should consider the risks and benefits when prescribing olanzapine to patients with an established diagnosis of diabetes mellitus, or having borderline increased blood glucose level (fasting 100 to 126 mg/dL, nonfasting 140 to 200 mg/dL).

Patients taking olanzapine should be monitored regularly for worsening of glucose control.

Patients starting treatment with olanzapine should undergo fasting blood glucose testing at the beginning of treatment and periodically during treatment.

Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness.

Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing.

In some cases, hyperglycemia has resolved when the atypical antipsychotic was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the suspect drug [see Patient Counseling Information (17) ] .

Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics including olanzapine.

Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population.

Epidemiological studies suggest an increased risk of treatment-emergent hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics.

While relative risk estimates are inconsistent, the association between atypical antipsychotics and increases in glucose levels appears to fall on a continuum and olanzapine appears to have a greater association than some other atypical antipsychotics.

Mean increases in blood glucose have been observed in patients treated (median exposure of 9.2 months) with olanzapine in phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE).

The mean increase of serum glucose (fasting and nonfasting samples) from baseline to the average of the 2 highest serum concentrations was 15.0 mg/dL.

In a study of healthy volunteers, subjects who received olanzapine (N=22) for 3 weeks had a mean increase compared to baseline in fasting blood glucose of 2.3 mg/dL.

Placebo-treated subjects (N=19) had a mean increase in fasting blood glucose compared to baseline of 0.34 mg/dL.

Olanzapine Monotherapy in Adults — In an analysis of 5 placebo-controlled adult olanzapine monotherapy studies with a median treatment duration of approximately 3 weeks, olanzapine was associated with a greater mean change in fasting glucose levels compared to placebo (2.76 mg/dL versus 0.17 mg/dL).

The difference in mean changes between olanzapine and placebo was greater in patients with evidence of glucose dysregulation at baseline (patients diagnosed with diabetes mellitus or related adverse reactions, patients treated with anti-diabetic agents, patients with a baseline random glucose level ≥200 mg/dL, and/or a baseline fasting glucose level ≥126 mg/dL).

Olanzapine-treated patients had a greater mean HbA 1c increase from baseline of 0.04% (median exposure 21 days), compared to a mean HbA 1c decrease of 0.06% in placebo-treated subjects (median exposure 17 days).

In an analysis of 8 placebo-controlled studies (median treatment exposure 4-5 weeks), 6.1% of olanzapine-treated subjects (N=855) had treatment-emergent glycosuria compared to 2.8% of placebo-treated subjects (N=599).

Table 2 shows short-term and long-term changes in fasting glucose levels from adult olanzapine monotherapy studies.

Table 2: Changes in Fasting Glucose Levels from Adult Olanzapine Monotherapy Studies Up to 12 weeks exposure At least 48 weeks exposure Laboratory Analyte Category Change (at least once) from Baseline Treatment Arm N Patients N Patients Fasting Glucose Normal to High (<100 mg/dL to ≥126 mg/dL) Olanzapine 543 2.2% 345 12.8% Placebo 293 3.4% NA a NA a Borderline to High (≥100 mg/dL and <126 mg/dL to ≥126 mg/dL) Olanzapine 178 17.4% 127 26% Placebo 96 11.5% NA a NA a a Not Applicable.

The mean change in fasting glucose for patients exposed at least 48 weeks was 4.2 mg/dL (N=487).

In analyses of patients who completed 9 to 12 months of olanzapine therapy, mean change in fasting and nonfasting glucose levels continued to increase over time.

Olanzapine Monotherapy in Adolescents — The safety and efficacy of olanzapine have not been established in patients under the age of 13 years.

In an analysis of 3 placebo-controlled olanzapine monotherapy studies of adolescent patients, including those with schizophrenia (6 weeks) or bipolar I disorder (manic or mixed episodes) (3 weeks), olanzapine was associated with a greater mean change from baseline in fasting glucose levels compared to placebo (2.68 mg/dL versus -2.59 mg/dL).

The mean change in fasting glucose for adolescents exposed at least 24 weeks was 3.1 mg/dL (N=121).

Table 3 shows short-term and long-term changes in fasting blood glucose from adolescent olanzapine monotherapy studies.

Dyslipidemia Undesirable alterations in lipids have been observed with olanzapine use.

Clinical monitoring, including baseline and periodic follow-up lipid evaluations in patients using olanzapine, is recommended [see Patient Counseling Information (17)].

Clinically significant, and sometimes very high (>500 mg/dL), elevations in triglyceride levels have been observed with olanzapine use.

Modest mean increases in total cholesterol have also been seen with olanzapine use.

Olanzapine Monotherapy in Adults — In an analysis of 5 placebo-controlled olanzapine monotherapy studies with treatment duration up to 12 weeks, olanzapine-treated patients had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.3 mg/dL, 3.0 mg/dL, and 20.8 mg/dL respectively compared to decreases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 6.1 mg/dL, 4.3 mg/dL, and 10.7 mg/dL for placebo-treated patients.

For fasting HDL cholesterol, no clinically meaningful differences were observed between olanzapine-treated patients and placebo-treated patients.

Mean increases in fasting lipid values (total cholesterol, LDL cholesterol, and triglycerides) were greater in patients without evidence of lipid dysregulation at baseline, where lipid dysregulation was defined as patients diagnosed with dyslipidemia or related adverse reactions, patients treated with lipid lowering agents, or patients with high baseline lipid levels.

In long-term studies (at least 48 weeks), patients had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.6 mg/dL, 2.5 mg/dL, and 18.7 mg/dL, respectively, and a mean decrease in fasting HDL cholesterol of 0.16 mg/dL.

In an analysis of patients who completed 12 months of therapy, the mean nonfasting total cholesterol did not increase further after approximately 4-6 months.

The proportion of patients who had changes (at least once) in total cholesterol, LDL cholesterol or triglycerides from normal or borderline to high, or changes in HDL cholesterol from normal or borderline to low, was greater in long-term studies (at least 48 weeks) as compared with short-term studies.

In phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE), over a median exposure of 9.2 months, the mean increase in triglycerides in patients taking olanzapine was 40.5 mg/dL.

In phase 1 of CATIE, the mean increase in total cholesterol was 9.4 mg/dL.

Olanzapine Monotherapy in Adolescents — The safety and efficacy of olanzapine have not been established in patients under the age of 13 years.

In an analysis of 3 placebo-controlled olanzapine monotherapy studies of adolescents, including those with schizophrenia (6 weeks) or bipolar I disorder (manic or mixed episodes) (3 weeks), olanzapine-treated adolescents had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 12.9 mg/dL, 6.5 mg/dL, and 28.4 mg/dL, respectively, compared to increases from baseline in mean fasting total cholesterol and LDL cholesterol of 1.3 mg/dL and 1.0 mg/dL, and a decrease in triglycerides of 1.1 mg/dL for placebo-treated adolescents.

For fasting HDL cholesterol, no clinically meaningful differences were observed between olanzapine-treated adolescents and placebo-treated adolescents.

In long-term studies (at least 24 weeks), adolescents had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.5 mg/dL, 5.4 mg/dL, and 20.5 mg/dL, respectively, and a mean decrease in fasting HDL cholesterol of 4.5 mg/dL.

Table 5 shows categorical changes in fasting lipids values in adolescents.

Weight Gain Potential consequences of weight gain should be considered prior to starting olanzapine.

Patients receiving olanzapine should receive regular monitoring of weight [see Patient Counseling Information (17) ] .

Olanzapine Monotherapy in Adults — In an analysis of 13 placebo-controlled olanzapine monotherapy studies, olanzapine-treated patients gained an average of 2.6 kg (5.7 lb) compared to an average 0.3 kg (0.6 lb) weight loss in placebo-treated patients with a median exposure of 6 weeks; 22.2% of olanzapine-treated patients gained at least 7% of their baseline weight, compared to 3% of placebo-treated patients, with a median exposure to event of 8 weeks; 4.2% of olanzapine-treated patients gained at least 15% of their baseline weight, compared to 0.3% of placebo-treated patients, with a median exposure to event of 12 weeks.

Clinically significant weight gain was observed across all baseline Body Mass Index (BMI) categories.

Discontinuation due to weight gain occurred in 0.2% of olanzapine-treated patients and in 0% of placebo-treated patients.

In long-term studies (at least 48 weeks), the mean weight gain was 5.6 kg (12.3 lb) (median exposure of 573 days, N=2021).

The percentages of patients who gained at least 7%, 15%, or 25% of their baseline body weight with long-term exposure were 64%, 32%, and 12%, respectively.

Discontinuation due to weight gain occurred in 0.4% of olanzapine-treated patients following at least 48 weeks of exposure.

Table 6 includes data on adult weight gain with olanzapine pooled from 86 clinical trials.

The data in each column represent data for those patients who completed treatment periods of the durations specified.

In a single 8-week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200) and 40 (N=200) mg/day of oral olanzapine in adult patients with schizophrenia or schizoaffective disorder, mean baseline to endpoint increase in weight (10 mg/day: 1.9 kg; 20 mg/day: 2.3 kg; 40 mg/day: 3 kg) was observed with significant differences between 10 vs 40 mg/day.

Olanzapine Monotherapy in Adolescents – The safety and efficacy of olanzapine have not been established in patients under the age of 13 years.

Mean increase in weight in adolescents was greater than in adults.

In 4 placebo-controlled trials, discontinuation due to weight gain occurred in 1% of olanzapine-treated patients, compared to 0% of placebo-treated patients.

The percentages of adolescents who gained at least 7%, 15%, or 25% of their baseline body weight with long-term exposure were 89%, 55%, and 29%, respectively.

Among adolescent patients, mean weight gain by baseline BMI category was 11.5 kg (25.3 lb), 12.1 kg (26.6 lb), and 12.7 kg (27.9 lb), respectively, for normal (N=106), overweight (N=26) and obese (N=17).

Discontinuation due to weight gain occurred in 2.2% of olanzapine-treated patients following at least 24 weeks of exposure.

Table 8 shows data on adolescent weight gain with olanzapine pooled from 6 clinical trials.

The data in each column represent data for those patients who completed treatment periods of the durations specified.

Little clinical trial data is available on weight gain in adolescents with olanzapine beyond 6 months of treatment.

Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome.

Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown.

The risk of developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase.

However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses or may even arise after discontinuation of treatment.

Tardive dyskinesia may remit, partially or completely, if antipsychotic treatment is withdrawn.

Antipsychotic treatment, itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome and thereby may possibly mask the underlying process.

The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown.

Given these considerations, olanzapine should be prescribed in a manner that is most likely to minimize the occurrence of tardive dyskinesia.

Chronic antipsychotic treatment should generally be reserved for patients (1) who suffer from a chronic illness that is known to respond to antipsychotic drugs, and (2) for whom alternative, equally effective, but potentially less harmful treatments are not available or appropriate.

In patients who do require chronic treatment, the smallest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought.

The need for continued treatment should be reassessed periodically.

If signs and symptoms of tardive dyskinesia appear in a patient on olanzapine, drug discontinuation should be considered.

However, some patients may require treatment with olanzapine despite the presence of the syndrome.

For specific information about the warnings of lithium or valproate, refer to the Warnings section of the package inserts for these other products.

5.7 Orthostatic Hypotension Olanzapine may induce orthostatic hypotension associated with dizziness, tachycardia, bradycardia and, in some patients, syncope, especially during the initial dose-titration period, probably reflecting its α 1 -adrenergic antagonistic properties [see Patient Counseling Information (17) ] .

From an analysis of the vital sign data in an integrated database of 41 completed clinical studies in adult patients treated with oral olanzapine, orthostatic hypotension was recorded in ≥20% (1277/6030) of patients.

For oral olanzapine therapy, the risk of orthostatic hypotension and syncope may be minimized by initiating therapy with 5 mg QD [see Dosage and Administration (2) ] .

A more gradual titration to the target dose should be considered if hypotension occurs.

Syncope was reported in 0.6% (15/2500) of olanzapine-treated patients in phase 2-3 oral olanzapine studies.

The risk for this sequence of hypotension, bradycardia, and sinus pause may be greater in nonpsychiatric patients compared to psychiatric patients who are possibly more adapted to certain effects of psychotropic drugs.

Olanzapine should be used with particular caution in patients with known cardiovascular disease (history of myocardial infarction or ischemia, heart failure, or conduction abnormalities), cerebrovascular disease, and conditions which would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medications) where the occurrence of syncope, or hypotension and/or bradycardia might put the patient at increased medical risk.

Caution is necessary in patients who receive treatment with other drugs having effects that can induce hypotension, bradycardia, respiratory or central nervous system depression [see Drug Interactions (7) ] .

5.8 Falls Olanzapine may cause somnolence, postural hypotension, motor and sensory instability, which may lead to falls and, consequently, fractures or other injuries.

For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy.

5.9 Leukopenia, Neutropenia, and Agranulocytosis Class Effect — In clinical trial and/or postmarketing experience, events of leukopenia/neutropenia have been reported temporally related to antipsychotic agents, including olanzapine.

Agranulocytosis has also been reported.

Possible risk factors for leukopenia/neutropenia include pre-existing low white blood cell count (WBC) and history of drug induced leukopenia/neutropenia.

Patients with a history of a clinically significant low WBC or drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and discontinuation of olanzapine should be considered at the first sign of a clinically significant decline in WBC in the absence of other causative factors.

Patients with clinically significant neutropenia should be carefully monitored for fever or other symptoms or signs of infection and treated promptly if such symptoms or signs occur.

Patients with severe neutropenia (absolute neutrophil count <1000/mm 3 ) should discontinue olanzapine and have their WBC followed until recovery.

5.10 Dysphagia Esophageal dysmotility and aspiration have been associated with antipsychotic drug use.

Aspiration pneumonia is a common cause of morbidity and mortality in patients with advanced Alzheimer’s disease.

Olanzapine is not approved for the treatment of patients with Alzheimer’s disease.

5.11 Seizures During premarketing testing, seizures occurred in 0.9% (22/2500) of olanzapine-treated patients.

There were confounding factors that may have contributed to the occurrence of seizures in many of these cases.

Olanzapine should be used cautiously in patients with a history of seizures or with conditions that potentially lower the seizure threshold, e.g., Alzheimer’s dementia.

Olanzapine is not approved for the treatment of patients with Alzheimer’s disease.

Conditions that lower the seizure threshold may be more prevalent in a population of 65 years or older.

5.12 Potential for Cognitive and Motor Impairment Somnolence was a commonly reported adverse reaction associated with olanzapine treatment, occurring at an incidence of 26% in olanzapine patients compared to 15% in placebo patients.

This adverse reaction was also dose related.

Somnolence led to discontinuation in 0.4% (9/2500) of patients in the premarketing database.

Since olanzapine has the potential to impair judgment, thinking, or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine therapy does not affect them adversely [see Patient Counseling Information (17) ] .

5.13 Body Temperature Regulation Disruption of the body’s ability to reduce core body temperature has been attributed to antipsychotic agents.

Appropriate care is advised when prescribing olanzapine for patients who will be experiencing conditions which may contribute to an elevation in core body temperature, e.g., exercising strenuously, exposure to extreme heat, receiving concomitant medication with anticholinergic activity, or being subject to dehydration [see Patient Counseling Information (17) ].

5.14 Anticholinergic (antimuscarinic) Effects Olanzapine exhibits in vitro muscarinic receptor affinity [see Clinical Pharmacology 12.2 ] .

In premarketing clinical trials, olanzapine was associated with constipation, dry mouth, and tachycardia, all adverse reactions possibly related to cholinergic antagonism.

Such adverse reactions were not often the basis for discontinuations, but olanzapine should be used with caution in patients with a current diagnosis or prior history of urinary retention, clinically significant prostatic hypertrophy, constipation, or a history of paralytic ileus or related conditions.

In post marketing experience, the risk for severe adverse reactions (including fatalities) was increased with concomitant use of anticholinergic medications [see Drug Interactions (7.1 )].

5.15 Hyperprolactinemia As with other drugs that antagonize dopamine D 2 receptors, olanzapine elevates prolactin levels, and the elevation persists during chronic administration.

Hyperprolactinemia may suppress hypothalamic GnRH, resulting in reduced pituitary gonadotropin secretion.

This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients.

Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds.

Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male subjects.

Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin dependent in vitro , a factor of potential importance if the prescription of these drugs is contemplated in a patient with previously detected breast cancer.

As is common with compounds which increase prolactin release, an increase in mammary gland neoplasia was observed in the olanzapine carcinogenicity studies conducted in mice and rats [see Nonclinical Toxicology (13.1) ] .

Neither clinical studies nor epidemiologic studies conducted to date have shown an association between chronic administration of this class of drugs and tumorigenesis in humans; the available evidence is considered too limited to be conclusive at this time.

In placebo-controlled olanzapine clinical studies (up to 12 weeks), changes from normal to high in prolactin concentrations were observed in 30% of adults treated with olanzapine as compared to 10.5% of adults treated with placebo.

In a pooled analysis from clinical studies including 8136 adults treated with olanzapine, potentially associated clinical manifestations included menstrual-related events 1 (2% [49/3240] of females), sexual function-related events 2 (2% [150/8136] of females and males), and breast-related events 3 (0.7% [23/3240] of females, 0.2% [9/4896] of males).

In placebo-controlled olanzapine monotherapy studies in adolescent patients (up to 6 weeks) with schizophrenia or bipolar I disorder (manic or mixed episodes), changes from normal to high in prolactin concentrations were observed in 47% of olanzapine­-treated patients compared to 7% of placebo-treated patients.

In a pooled analysis from clinical trials including 454 adolescents treated with olanzapine, potentially associated clinical manifestations included menstrual-related events 1 (1% [2/168] of females), sexual function-related events 2 (0.7% [3/454] of females and males), and breast-related events 3 (2% [3/168] of females, 2% [7/286] of males) [see Use in Specific Populations (8.4) ] .

1 Based on a search of the following terms: amenorrhea, hypomenorrhea, menstruation delayed, and oligomenorrhea.

2 Based on a search of the following terms: anorgasmia, delayed ejaculation, erectile dysfunction, decreased libido, loss of libido, abnormal orgasm, and sexual dysfunction.

3 Based on a search of the following terms: breast discharge, enlargement or swelling, galactorrhea, gynecomastia, and lactation disorder.

Dose group differences with respect to prolactin elevation have been observed.

In a single 8-week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200) and 40 (N=200) mg/day of oral olanzapine in adult patients with schizophrenia or schizoaffective disorder, incidence of prolactin elevation >24.2 ng/mL (female) or >18.77 ng/mL (male) at any time during the trial (10 mg/day: 31.2%; 20 mg/day: 42.7%; 40 mg/day: 61.1%) indicated significant differences between 10 vs 40 mg/day and 20 vs 40 mg/day.

5.16 Use in Combination with Fluoxetine, Lithium, or Valproate When using olanzapine and fluoxetine in combination, the prescriber should also refer to the Warnings and Precautions section of the package insert for Symbyax.

When using olanzapine in combination with lithium or valproate, the prescriber should refer to the Warnings and Precautions sections of the package inserts for lithium or valproate [see Drug Interactions (7) ].

5.17 Laboratory Tests Fasting blood glucose testing and lipid profile at the beginning of, and periodically during, treatment is recommended [see Warnings and Precautions (5.5) and Patient Counseling Information (17 )].

INFORMATION FOR PATIENTS

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide) for the oral formulations.

When using olanzapine and fluoxetine in combination, also refer to the Patient Counseling Information section of the package insert for Symbyax.

Elderly Patients with Dementia-Related Psychosis: Increased Mortality and Cerebrovascular Adverse Events (CVAE), Including Stroke Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with olanzapine had a significantly higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) compared with placebo.

Olanzapine is not approved for elderly patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions (5.1)] .

Neuroleptic Malignant Syndrome (NMS) Patients and caregivers should be counseled that a potentially fatal symptom complex sometimes referred to as NMS has been reported in association with administration of antipsychotic drugs, including olanzapine.

Signs and symptoms of NMS include hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia) [see Warnings and Precautions (5.3)] .

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Patients should be advised to report to their health care provider at the earliest onset of any signs and symptoms that may be associated with Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) [see Warnings and Precautions (5.4)] .

Hyperglycemia and Diabetes Mellitus Patients should be advised of the potential risk of hyperglycemia-related adverse reactions.

Patients should be monitored regularly for worsening of glucose control.

Patients who have diabetes should follow their doctor’s instructions about how often to check their blood sugar while taking olanzapine [see Warnings and Precautions (5.5)] .

Dyslipidemia Patients should be counseled that dyslipidemia has occurred during treatment with olanzapine.

Patients should have their lipid profile monitored regularly [see Warnings and Precautions (5.5)] .

Weight Gain Patients should be counseled that weight gain has occurred during treatment with olanzapine.

Patients should have their weight monitored regularly [see Warnings and Precautions (5.5)] .

Orthostatic Hypotension Patients should be advised of the risk of orthostatic hypotension, especially during the period of initial dose titration and in association with the use of concomitant drugs that may potentiate the orthostatic effect of olanzapine, e.g., diazepam or alcohol [see Warnings and Precautions (5.7) and Drug Interactions (7)] .

Patients should be advised to change positions carefully to help prevent orthostatic hypotension, and to lie down if they feel dizzy or faint, until they feel better.

Patients should be advised to call their doctor if they experience any of the following signs and symptoms associated with orthostatic hypotension: dizziness, fast or slow heartbeat, or fainting.

Potential for Cognitive and Motor Impairment Because olanzapine has the potential to impair judgment, thinking, or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine therapy does not affect them adversely [see Warnings and Precautions (5.12)] .

Body Temperature Regulation Patients should be advised regarding appropriate care in avoiding overheating and dehydration.

Patients should be advised to call their doctor right away if they become severely ill and have some or all of these symptoms of dehydration: sweating too much or not at all, dry mouth, feeling very hot, feeling thirsty, not able to produce urine [see Warnings and Precautions (5.13)] .

Concomitant Medication Patients should be advised to inform their healthcare providers if they are taking, or plan to take, Symbyax.

Patients should also be advised to inform their healthcare providers if they are taking, plan to take, or have stopped taking any prescription or over-the-counter drugs, including herbal supplements, since there is a potential for interactions [see Drug Interactions (7)] .

Alcohol Patients should be advised to avoid alcohol while taking olanzapine [see Drug Interactions (7)] .

Phenylketonurics Olanzapine orally disintegrating tablets contain phenylalanine (1.12, 2.24, 3.36, or 4.48 mg per 5, 10, 15, or 20 mg tablet, respectively) [see Description (11)].

Use in Specific Populations Pregnancy — Advise women to notify their healthcare provider if they become pregnant or intend to become pregnant during treatment with olanzapine.

Advise patients that olanzapine may cause extrapyramidal and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder) in a neonate.

Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to olanzapine during pregnancy [see Use in Specific Populations (8.1)] .

Lactation — Advise breastfeeding women using olanzapine to monitor infants for excess sedation, irritability, poor feeding and extrapyramidal symptoms (tremors and abnormal muscle movements) and to seek medical care if they notice these signs.

[see Use in Specific Populations (8.3)] .

Infertility — Advise females of reproductive potential that olanzapine may impair fertility due to an increase in serum prolactin levels.

The effects on fertility are reversible [see Use in Specific Populations (8.3)].

Pediatric Use — Olanzapine is indicated for treatment of schizophrenia and manic or mixed episodes associated with bipolar I disorder in adolescents 13 to 17 years of age.

Compared to patients from adult clinical trials, adolescents were likely to gain more weight, experience increased sedation, and have greater increases in total cholesterol, triglycerides, LDL cholesterol, prolactin, and hepatic aminotransferase levels.

Patients should be counseled about the potential long-term risks associated with olanzapine and advised that these risks may lead them to consider other drugs first [see Indications and Usage (1.1, 1.2)] .

Safety and effectiveness of olanzapine in patients under 13 years of age have not been established.

Safety and efficacy of olanzapine and fluoxetine in combination in patients 10 to 17 years of age have been established for the acute treatment of depressive episodes associated with bipolar I disorder.

Safety and effectiveness of olanzapine and fluoxetine in combination in patients <10 years of age have not been established [see Warnings and Precautions (5.5) and Use in Specific Populations (8.4)] .

Need for Comprehensive Treatment Program in Pediatric Patients Olanzapine is indicated as an integral part of a total treatment program for pediatric patients with schizophrenia and bipolar disorder that may include other measures (psychological, educational, social) for patients with the disorder.

Effectiveness and safety of olanzapine have not been established in pediatric patients less than 13 years of age.

Atypical antipsychotics are not intended for use in the pediatric patient who exhibits symptoms secondary to environmental factors and/or other primary psychiatric disorders.

Appropriate educational placement is essential and psychosocial intervention is often helpful.

The decision to prescribe atypical antipsychotic medication will depend upon the healthcare provider’s assessment of the chronicity and severity of the patient’s symptoms [see Indications and Usage (1.3)] .

( 2.1 ) Olanzapine may be given without regard to meals.

( 2.1 ) Olanzapine and Fluoxetine in Combination: Dosage adjustments, if indicated, should be made with the individual components according to efficacy and tolerability.

( 2.5, 2.6 ) Olanzapine monotherapy is not indicated for the treatment of depressive episodes associated with bipolar I disorder or treatment resistant depression.

( 2.5, 2.6 ) Safety of co-administration of doses above 18 mg olanzapine with 75 mg fluoxetine has not been evaluated in adults.

( 2.5, 2.6 ) Safety of co-administration of doses above 12 mg olanzapine with 50 mg fluoxetine has not been evaluated in children and adolescents ages 10 to 17.

(2.5) 2.1 Schizophrenia Adults Dose Selection — Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 5 to 10 mg initially, with a target dose of 10 mg/day within several days.

Further dosage adjustments, if indicated, should generally occur at intervals of not less than 1 week, since steady state for olanzapine would not be achieved for approximately 1 week in the typical patient.

When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended.

Efficacy in schizophrenia was demonstrated in a dose range of 10 to 15 mg/day in clinical trials.

However, doses above 10 mg/day were not demonstrated to be more efficacious than the 10 mg/day dose.

An increase to a dose greater than the target dose of 10 mg/day (i.e., to a dose of 15 mg/day or greater) is recommended only after clinical assessment.

Olanzapine is not indicated for use in doses above 20 mg/day.

Dosing in Special Populations — The recommended starting dose is 5 mg in patients who are debilitated, who have a predisposition to hypotensive reactions, who otherwise exhibit a combination of factors that may result in slower metabolism of olanzapine (e.g., nonsmoking female patients ≥65 years of age), or who may be more pharmacodynamically sensitive to olanzapine [see Warnings and Precautions (5.14), Drug Interactions (7) , and Clinical Pharmacology (12.3) ] .

When indicated, dose escalation should be performed with caution in these patients.

Maintenance Treatment — The effectiveness of oral olanzapine, 10 mg/day to 20 mg/day, in maintaining treatment response in schizophrenic patients who had been stable on olanzapine orally disintegrating tablets for approximately 8 weeks and were then followed for relapse has been demonstrated in a placebo-controlled trial [see Clinical Studies (14.1) ] .

The healthcare provider who elects to use olanzapine orally disintegrating tablets for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

Adolescents Dose Selection — Oral olanzapine should be administered on a once-a-day schedule without regard to meals with a recommended starting dose of 2.5 or 5 mg, with a target dose of 10 mg/day.

Efficacy in adolescents with schizophrenia was demonstrated based on a flexible dose range of 2.5 to 20 mg/day in clinical trials, with a mean modal dose of 12.5 mg/day (mean dose of 11.1 mg/day).

When dosage adjustments are necessary, dose increments/decrements of 2.5 or 5 mg are recommended.

The safety and effectiveness of doses above 20 mg/day have not been evaluated in clinical trials [ see Clinical Studies (14.1)] .

Maintenance Treatment — The efficacy of olanzapine orally disintegrating tablets for the maintenance treatment of schizophrenia in the adolescent population has not been systematically evaluated; however, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients.

Thus, it is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission.

Patients should be periodically reassessed to determine the need for maintenance treatment.

2.2 Bipolar I Disorder (Manic or Mixed Episodes) Adults Dose Selection for Monotherapy — Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 10 or 15 mg.

Dosage adjustments, if indicated, should generally occur at intervals of not less than 24 hours, reflecting the procedures in the placebo-controlled trials.

When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended.

Short-term (3-4 weeks) antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials.

The safety of doses above 20 mg/day has not been evaluated in clinical trials [see Clinical Studies (14.2)].

Maintenance Monotherapy — The benefit of maintaining bipolar I patients on monotherapy with olanzapine orally disintegrating tablets at a dose of 5 to 20 mg/day, after achieving a responder status for an average duration of 2 weeks, was demonstrated in a controlled trial [ see Clinical Studies (14.2) ] .

The healthcare provider who elects to use olanzapine orally disintegrating tablets for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

Dose Selection for Adjunctive Treatment — When administered as adjunctive treatment to lithium or valproate, oral olanzapine dosing should generally begin with 10 mg once-a-day without regard to meals.

Antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials [see Clinical Studies (14.2)] .

The safety of doses above 20 mg/day has not been evaluated in clinical trials.

Adolescents Dose Selection — Oral olanzapine should be administered on a once-a-day schedule without regard to meals with a recommended starting dose of 2.5 or 5 mg, with a target dose of 10 mg/day.

Efficacy in adolescents with bipolar I disorder (manic or mixed episodes) was demonstrated based on a flexible dose range of 2.5 to 20 mg/day in clinical trials, with a mean modal dose of 10.7 mg/day (mean dose of 8.9 mg/day).

When dosage adjustments are necessary, dose increments/decrements of 2.5 or 5 mg are recommended.

The safety and effectiveness of doses above 20 mg/day have not been evaluated in clinical trials [see Clinical Studies (14.2)] .

Maintenance Treatment — The efficacy of olanzapine orally disintegrating tablets for the maintenance treatment of bipolar I disorder in the adolescent population has not been evaluated; however, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients.

Thus, it is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission.

Patients should be periodically reassessed to determine the need for maintenance treatment.

Do not push tablet through foil.

Immediately upon opening the blister, using dry hands, remove tablet and place entire olanzapine orally disintegrating tablet in the mouth.

Tablet disintegration occurs rapidly in saliva so it can be easily swallowed with or without liquid.

2.5 Olanzapine and Fluoxetine in Combination: Depressive Episodes Associated with Bipolar I Disorder When using olanzapine and fluoxetine in combination, also refer to the Clinical Studies section of the package insert for Symbyax.

Adults Oral olanzapine should be administered in combination with fluoxetine once daily in the evening, without regard to meals, generally beginning with 5 mg of oral olanzapine and 20 mg of fluoxetine.

Dosage adjustments, if indicated, can be made according to efficacy and tolerability within dose ranges of oral olanzapine 5 to 12.5 mg and fluoxetine 20 to 50 mg.

Antidepressant efficacy was demonstrated with olanzapine and fluoxetine in combination in adult patients with a dose range of olanzapine 6 to 12 mg and fluoxetine 25 to 50 mg.

Safety of co-administration of doses above 18 mg olanzapine with 75 mg fluoxetine has not been evaluated in clinical studies.

Children and Adolescents (10 to 17 years of age) Oral olanzapine should be administered in combination with fluoxetine once daily in the evening, without regard to meals, generally beginning with 2.5 mg of oral olanzapine and 20 mg of fluoxetine.

Dosage adjustments, if indicated, can be made according to efficacy and tolerability.

Safety of co-administration of doses above 12 mg olanzapine with 50 mg fluoxetine has not been evaluated in pediatric clinical studies.

Safety and efficacy of olanzapine and fluoxetine in combination was determined in clinical trials supporting approval of Symbyax (fixed dose combination of olanzapine and fluoxetine).

Symbyax is dosed between 3 mg/25 mg (olanzapine/fluoxetine) per day and 12 mg/50 mg (olanzapine/fluoxetine) per day.

The following table demonstrates the appropriate individual component doses of olanzapine and fluoxetine versus Symbyax.

Dosage adjustments, if indicated, should be made with the individual components according to efficacy and tolerability.

Table 1: Approximate Dose Correspondence Between Symbyax a and the Combination of Olanzapine and Fluoxetine For Symbyax (mg/day) Use in Combination Olanzapine (mg/day) Fluoxetine (mg/day) 3 mg olanzapine/25 mg fluoxetine 2.5 20 6 mg olanzapine/25 mg fluoxetine 5 20 12 mg olanzapine/25 mg fluoxetine 10+2.5 20 6 mg olanzapine/50 mg fluoxetine 5 40+10 12 mg olanzapine/50 mg fluoxetine 10+2.5 40+10 a Symbyax (olanzapine/fluoxetine HCl) is a fixed-dose combination of olanzapine and fluoxetine.

While there is no body of evidence to answer the question of how long a patient treated with olanzapine and fluoxetine in combination should remain on it, it is generally accepted that bipolar I disorder, including the depressive episodes associated with bipolar I disorder, is a chronic illness requiring chronic treatment.

The healthcare provider should periodically reexamine the need for continued pharmacotherapy.

Olanzapine orally disintegrating tablets monotherapy is not indicated for the treatment of depressive episodes associated with bipolar I disorder.

2.6 Olanzapine and Fluoxetine in Combination: Treatment Resistant Depression When using olanzapine and fluoxetine in combination, also refer to the Clinical Studies section of the package insert for Symbyax.

Oral olanzapine should be administered in combination with fluoxetine once daily in the evening, without regard to meals, generally beginning with 5 mg of oral olanzapine and 20 mg of fluoxetine.

Dosage adjustments, if indicated, can be made according to efficacy and tolerability within dose ranges of oral olanzapine 5 to 20 mg and fluoxetine 20 to 50 mg.

Antidepressant efficacy was demonstrated with olanzapine and fluoxetine in combination in adult patients with a dose range of olanzapine 6 to 18 mg and fluoxetine 25 to 50 mg.

Safety and efficacy of olanzapine in combination with fluoxetine was determined in clinical trials supporting approval of Symbyax (fixed dose combination of olanzapine and fluoxetine).

Symbyax is dosed between 3 mg/25 mg (olanzapine/fluoxetine) per day and 12 mg/50 mg (olanzapine/fluoxetine) per day.

Table 1 above demonstrates the appropriate individual component doses of olanzapine and fluoxetine versus Symbyax.

Dosage adjustments, if indicated, should be made with the individual components according to efficacy and tolerability.

While there is no body of evidence to answer the question of how long a patient treated with olanzapine and fluoxetine in combination should remain on it, it is generally accepted that treatment resistant depression (major depressive disorder in adult patients who do not respond to 2 separate trials of different antidepressants of adequate dose and duration in the current episode) is a chronic illness requiring chronic treatment.

The healthcare provider should periodically reexamine the need for continued pharmacotherapy.

Safety of co-administration of doses above 18 mg olanzapine with 75 mg fluoxetine has not been evaluated in clinical studies.

Olanzapine orally disintegrating tablets monotherapy is not indicated for treatment of treatment resistant depression (major depressive disorder in patients who do not respond to 2 antidepressants of adequate dose and duration in the current episode).

2.7 Olanzapine and Fluoxetine in Combination: Dosing in Special Populations The starting dose of oral olanzapine 2.5 to 5 mg with fluoxetine 20 mg should be used for patients with a predisposition to hypotensive reactions, patients with hepatic impairment, or patients who exhibit a combination of factors that may slow the metabolism of olanzapine or fluoxetine in combination (female gender, geriatric age, nonsmoking status), or those patients who may be pharmacodynamically sensitive to olanzapine.

Dosing modification may be necessary in patients who exhibit a combination of factors that may slow metabolism.

When indicated, dose escalation should be performed with caution in these patients.

Olanzapine and fluoxetine in combination have not been systematically studied in patients over 65 years of age or in patients under 10 years of age [see Warnings and Precautions (5.14) , Drug Interactions (7) , and Clinical Pharmacology (12.3) ] .

DRUG INTERACTIONS

7 Table 5 includes clinically important drug interactions with REMERON/REMERONSolTab [see Clinical Pharmacology (12.3) ].

Table 5: Clinically Important Drug Interactions with REMERON/REMERONSolTab Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact The concomitant use of serotonergic drugs, including REMERON/REMERONSolTab, and MAOIs increases the risk of serotonin syndrome.

Intervention REMERON/REMERONSolTab is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Dosage and Administration (2.4) , Contraindications (4) , Warnings and Precautions (5.3) ].

Examples selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue Other Serotonergic Drugs Clinical Impact The concomitant use of serotonergic drugs with REMERON/REMERONSolTab increases the risk of serotonin syndrome.

Intervention Monitor patients for signs and symptoms of serotonin syndrome, particularly during treatment initiation and dosage increases.

If serotonin syndrome occurs, consider discontinuation of REMERON/REMERONSolTab and/or concomitant serotonergic drugs [see Warnings and Precautions (5.3) ].

Examples SSRIs, SNRIs, triptans, tricyclic antidepressants, fentanyl, lithium, amphetamines, St.

John’s Wort, tramadol, tryptophan, buspirone Strong CYP3A Inducers Clinical Impact The concomitant use of strong CYP3A inducers with REMERON/REMERONSolTab decreases the plasma concentration of mirtazapine [see Clinical Pharmacology (12.3) ] .

Intervention Increase the dose of REMERON/REMERONSolTab if needed with concomitant CYP3A inducer use.

Conversely, a decrease in dosage of REMERON/REMERONSolTab may be needed if the CYP3A inducer is discontinued [see Dosage and Administration (2.5) ].

Examples phenytoin, carbamazepine, rifampin Strong CYP3A Inhibitors Clinical Impact The concomitant use of strong CYP3A inhibitors with REMERON/REMERONSolTab may increase the plasma concentration of mirtazapine [see Clinical Pharmacology (12.3) ] .

Intervention Decrease the dose of REMERON/REMERONSolTab if needed with concomitant strong CYP3A inhibitor use.

Conversely, an increase in dosage of REMERON/REMERONSolTab may be needed if the CYP3A inhibitor is discontinued [see Dosage and Administration (2.5) ].

Examples itraconazole, ritonavir, nefazodone Cimetidine Clinical Impact The concomitant use of cimetidine, a CYP1A2, CYP2D6, and CYP3A inhibitor, with REMERON/REMERONSolTab may increase the plasma concentration of mirtazapine [see Clinical Pharmacology (12.3) ].

Intervention Decrease the dose of REMERON/REMERONSolTab if needed with concomitant cimetidine use.

Conversely, an increase in dosage of REMERON/REMERONSolTab may be needed if cimetidine is discontinued [see Dosage and Administration (2.5) ] .

Benzodiazepines and Alcohol Clinical Impact The concomitant use of benzodiazepines or alcohol with REMERON/REMERONSolTab increases the impairment of cognitive and motor skills produced by REMERON/REMERONSolTab alone.

Intervention Avoid concomitant use of benzodiazepines and alcohol with REMERON/REMERONSolTab [see Warnings and Precautions (5.7) , Clinical Pharmacology (12.3) ] ] .

Examples diazepam, alprazolam, alcohol Drugs that Prolong QTc Interval Clinical Impact The concomitant use of other drugs which prolong the QTc interval with REMERON/REMERONSolTab, increase the risk of QT prolongation and/or ventricular arrhythmias (e.g., Torsades de Pointes).

Intervention Use caution when using REMERON/REMERONSolTab concomitantly with drugs that prolong the QTc interval [see Warnings and Precautions (5.5) , Clinical Pharmacology (12.3) ].

Warfarin Clinical Impact The concomitant use of warfarin with REMERON/REMERONSolTab may result in an increase in INR [see Clinical Pharmacology (12.3) ] .

OVERDOSAGE

10 Human Experience In premarketing clinical studies, there were reports of REMERON overdose alone or in combination with other pharmacological agents.

Signs and symptoms reported in association with overdose included disorientation, drowsiness, impaired memory, and tachycardia.

Based on postmarketing reports, serious outcomes (including fatalities) may occur at dosages higher than the recommended doses, especially with mixed overdoses.

In these cases, QT prolongation and Torsades de Pointes have also been reported [see Warnings and Precautions (5.5) , Adverse Reactions (6.2) , and Drug Interactions (7) ].

Overdose Management No specific antidotes for mirtazapine are known.

Contact Poison Control (1-800-222-1222) for the latest recommendations.

Chemical Structure

CLINICAL STUDIES

14 The efficacy of REMERON as a treatment for major depressive disorder was established in 4 placebo-controlled, 6-week trials in adult outpatients meeting DSM-III criteria for major depressive disorder.

Patients were titrated with REMERON from a dose range of 5 mg to 35 mg/day.

The mean mirtazapine dose for patients who completed these 4 studies ranged from 21 to 32 mg/day.

Overall, these studies demonstrated REMERON to be superior to placebo on at least 3 of the following 4 measures: 21-Item Hamilton Depression Rating Scale (HDRS) total score; HDRS Depressed Mood Item; CGI Severity score; and Montgomery and Asberg Depression Rating Scale (MADRS).

Superiority of REMERON over placebo was also found for certain factors of the HDRS, including anxiety/somatization factor and sleep disturbance factor.

Examination of age and gender subsets of the population did not reveal any differential responsiveness on the basis of these subgroupings.

In a longer-term study, patients meeting (DSM-IV) criteria for major depressive disorder who had responded during an initial 8 to 12 weeks of acute treatment on REMERON were randomized to continuation of REMERON or placebo for up to 40 weeks of observation for relapse.

Response during the open phase was defined as having achieved a HAM-D 17 total score of ≤8 and a CGI-Improvement score of 1 or 2 at 2 consecutive visits beginning with week 6 of the 8 to 12 weeks in the open-label phase of the study.

Relapse during the double-blind phase was determined by the individual investigators.

Patients receiving continued REMERON treatment experienced significantly lower relapse rates over the subsequent 40 weeks compared to those receiving placebo.

This pattern was demonstrated in both male and female patients.

GERIATRIC USE

8.5 Geriatric Use Approximately 190 patients ≥65 years of age participated in clinical studies with REMERON.

REMERON/REMERONSolTab is known to be substantially excreted by the kidney (75%), and the risk of decreased clearance of this drug is greater in patients with impaired renal function.

Pharmacokinetic studies revealed a decreased clearance of mirtazapine in the elderly [see Clinical Pharmacology (12.3) ] .

Sedating drugs, including REMERON/REMERONSolTab, may cause confusion and over-sedation in the elderly.

Elderly patients may be at greater risk of developing hyponatremia.

Caution is indicated when administering REMERON/REMERONSolTab to elderly patients [see Warnings and Precautions (5.11) , (5.14) and Clinical Pharmacology (12.3) ] .

In general, dose selection for an elderly patient should be conservative, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

MECHANISM OF ACTION

12.1 Mechanism of Action The mechanism of action of mirtazapine for the treatment of major depressive disorder, is unclear.

However, its efficacy could be mediated through its activity as an antagonist at central presynaptic α 2 -adrenergic inhibitory autoreceptors and heteroreceptors and enhancing central noradrenergic and serotonergic activity.

INDICATIONS AND USAGE

1 REMERON/REMERONSolTab are indicated for the treatment of major depressive disorder (MDD) in adults [see Clinical Studies (14) ] .

REMERON/REMERONSolTab is indicated for the treatment of major depressive disorder (MDD) in adults.

( 1 )

PEDIATRIC USE

8.4 Pediatric Use The safety and effectiveness of REMERON/REMERONSolTab have not been established in pediatric patients with MDD.

Two placebo-controlled trials in 258 pediatric patients with MDD have been conducted with REMERON, and the data were insufficient to establish the safety and effectiveness of REMERON/REMERONSolTab in pediatric patients with MDD.

Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning and Warnings and Precautions (5.1) ] .

In an 8-week-long clinical trial in pediatric patients receiving doses between 15 to 45 mg per day, 49% of REMERON-treated patients had a weight gain of at least 7%, compared to 5.7% of placebo-treated patients.

The mean increase in weight was 4 kg (2 kg SD) for REMERON-treated patients versus 1 kg (2 kg SD) for placebo-treated patients [see Warnings and Precautions (5.6) ] .

PREGNANCY

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy.

Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/.

Risk Summary Prolonged experience with mirtazapine in pregnant women, based on published observational studies and postmarketing reports, has not reliably identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.

There are risks associated with untreated depression in pregnancy (see Clinical Considerations ).

In animal reproduction studies, oral administration of mirtazapine to pregnant rats and rabbits during the period of organogenesis revealed no evidence of teratogenic effects up to 20 and 17 times the maximum recommended human dose (MRHD) of 45 mg, respectively, based on mg/m 2 body surface area.

However, in rats, there was an increase in postimplantation loss at 20 times the MRHD based on mg/m 2 body surface area.

Oral administration of mirtazapine to pregnant rats during pregnancy and lactation resulted in an increase in pup deaths and a decrease in pup birth weights at doses 20 times the MRHD based on mg/m 2 body surface area (see Data ).

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.

All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

In the U.S.

general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants.

This finding is from a prospective, longitudinal study that followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy.

Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum.

Data Animal Data Mirtazapine was administered orally to pregnant rats and rabbits during the period of organogenesis at doses of 2.5, 15, and 100 mg/kg/day and 2.5, 10, and 40 mg/kg/day, respectively, which are up to 20 and 17 times the maximum recommended human dose (MRHD) of 45 mg based on mg/m 2 body surface area, respectively.

No evidence of teratogenic effects was observed.

However, in rats, there was an increase in postimplantation loss in dams treated with mirtazapine at 100 mg/kg/day which is 20 times the MRHD based on mg/m 2 body surface area.

Oral administration of mirtazapine at doses of 2.5, 15, and 100 mg/kg/day to pregnant rats during pregnancy and lactation resulted in an increase in pup deaths during the first 3 days of lactation and a decrease in pup birth weights at 20 times the MRHD based on mg/m 2 body surface area.

The cause of these deaths is not known.

The no effect dose level is 3 times the MRHD based on mg/m 2 body surface area.

BOXED WARNING

REMERON/REMERONSolTab is not approved for use in pediatric patients.

( 5.1 , 8.4 )

WARNING AND CAUTIONS

5 WARNINGS AND PRECAUTIONS Agranulocytosis : If sore throat, fever, stomatitis or signs of infection occur, along with a low white blood cell count, treatment with REMERON/REMERONSolTab should be discontinued and the patient should be closely monitored.

( 5.2 ) Serotonin Syndrome : Increased risk when co-administered with other serotonergic drugs (e.g., SSRI, SNRI, triptans), but also when taken alone.

If it occurs, discontinue REMERON/REMERONSolTab and initiate supportive treatment.

( 2.4 , 4 , 5.3 , 7 ) Angle-Closure Glaucoma : Angle closure glaucoma has occurred in patients with untreated anatomically narrow angles treated with antidepressants.

( 5.4 ) QT Prolongation : Use REMERON/REMERONSolTab with caution in patients with risk factors for QT prolongation.

( 5.5 , 7 ) Increased Appetite/Weight Gain : REMERON/REMERONSolTab has been associated with increased appetite and weight gain.

( 5.6 ) Somnolence : May impair judgment, thinking and/or motor skills.

Use with caution when engaging in activities requiring alertness, such as driving or operating machinery.

( 5.7 , 7 ) Activation of Mania/Hypomania : Screen patients for bipolar disorder prior to initiating treatment.

( 2.3 , 5.8 ) Seizures : Use with caution in patients with a seizure disorder.

( 5.9 ) Elevated Cholesterol/Triglycerides : Has been reported with REMERON use.

( 5.10 ) Hyponatremia : May occur as a result of treatment with serotonergic antidepressants, including REMERON/REMERONSolTab.

( 5.11 ) Transaminase Elevations : Clinically significant elevations have occurred.

Use with caution in patients with impaired hepatic function.

( 5.12 ) 5.1 Suicidal Thoughts and Behaviors in Adolescents and Young Adults In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients.

There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied.

There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD.

The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 1.

Table 1: Risk Differences of the Number of Patients with Suicidal Thoughts and Behavior in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients Age Range Drug-Placebo Difference in Number of Patients with Suicidal Thoughts or Behaviors per 1000 Patients Treated Increases Compared to Placebo <18 years old 14 additional patients 18–24 years old 5 additional patients Decreases Compared to Placebo 25–64 years old 1 fewer patient ≥65 years old 6 fewer patients It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months.

However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors.

Monitor all antidepressant-treated patients for any indication of clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy, and at times of dosage changes.

Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider.

Consider changing the therapeutic regimen, including possibly discontinuing REMERON/REMERONSolTab, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

5.2 Agranulocytosis In premarketing clinical trials, 2 (1 with Sjögren’s Syndrome) out of 2796 patients treated with REMERON developed agranulocytosis [absolute neutrophil count (ANC) <500/mm 3 with associated signs and symptoms, e.g., fever, infection, etc.] and a third patient developed severe neutropenia (ANC <500/mm 3 without any associated symptoms).

For these 3 patients, onset of severe neutropenia was detected on days 61, 9, and 14 of treatment, respectively.

All 3 patients recovered after REMERON was stopped.

If a patient develops a sore throat, fever, stomatitis, or other signs of infection, along with a low white blood cell (WBC) count, treatment with REMERON/REMERONSolTab should be discontinued and the patient should be closely monitored.

5.3 Serotonin Syndrome Serotonergic antidepressants, including REMERON/REMERONSolTab, can precipitate serotonin syndrome, a potentially life-threatening condition.

The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St.

John’s Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Contraindications (4) , Drug Interactions (7) ] .

Serotonin syndrome can also occur when these drugs are used alone.

Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).

The concomitant use of REMERON/REMERONSolTab with MAOIs is contraindicated.

In addition, do not initiate REMERON/REMERONSolTab in a patient being treated with MAOIs such as linezolid or intravenous methylene blue.

No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection).

If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking REMERON/REMERONSolTab, discontinue REMERON/REMERONSolTab before initiating treatment with the MAOI [see Contraindications (4) , Drug Interactions (7) ] .

Monitor all patients taking REMERON/REMERONSolTab for the emergence of serotonin syndrome.

Discontinue treatment with REMERON/REMERONSolTab and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment.

If concomitant use of REMERON/REMERONSolTab with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

5.4 Angle-Closure Glaucoma The pupillary dilation that occurs following use of many antidepressant drugs, including REMERON/REMERONSolTab, may trigger an angle-closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy.

5.5 QT Prolongation and Torsades de Pointes The effect of REMERON (mirtazapine) on QTc interval was assessed in a clinical randomized trial with placebo and positive (moxifloxacin) controls involving 54 healthy volunteers using exposure response analysis.

This trial showed a positive relationship between mirtazapine concentrations and prolongation of the QTc interval.

However, the degree of QT prolongation observed with both 45 mg and 75 mg (1.67 times the maximum recommended daily dose) doses of mirtazapine was not at a level generally considered to be clinically meaningful.

During postmarketing use of mirtazapine, cases of QT prolongation, Torsades de Pointes, ventricular tachycardia, and sudden death, have been reported [see Adverse Reactions (6.1 , 6.2) ] .

The majority of reports occurred in association with overdose or in patients with other risk factors for QT prolongation, including concomitant use of QTc-prolonging medicines [see Drug Interactions (7) and Overdosage (10) ] .

Exercise caution when REMERON/REMERONSolTab is prescribed in patients with known cardiovascular disease or family history of QT prolongation, and in concomitant use with other drugs thought to prolong the QTc interval.

5.6 Increased Appetite and Weight Gain In U.S.

controlled clinical studies, appetite increase was reported in 17% of patients treated with REMERON, compared to 2% for placebo.

In these same trials, weight gain of ≥7% of body weight was reported in 7.5% of patients treated with mirtazapine, compared to 0% for placebo.

In a pool of premarketing U.S.

clinical studies, including many patients for long-term, open-label treatment, 8% of patients receiving REMERON discontinued for weight gain.

In an 8-week-long pediatric clinical trial of doses between 15 to 45 mg/day, 49% of REMERON-treated pediatric patients had a weight gain of at least 7%, compared to 5.7% of placebo-treated patients.

The safety and effectiveness of REMERON/REMERONSolTab in pediatric patients with MDD have not been established [see Use in Specific Populations (8.4) ] .

5.7 Somnolence In U.S.

controlled studies, somnolence was reported in 54% of patients treated with REMERON, compared to 18% for placebo.

In these studies, somnolence resulted in discontinuation for 10.4% of REMERON-treated patients, compared to 2.2% for placebo.

It is unclear whether tolerance develops to the somnolent effects of REMERON/REMERONSolTab.

Because of the potentially significant effects of REMERON/REMERONSolTab on impairment of performance, caution patients about engaging in activities that require alertness, including operating hazardous machinery and motor vehicles, until they are reasonably certain that REMERON/REMERONSolTab does not affect them adversely.

The concomitant use of benzodiazepines and alcohol with REMERON/REMERONSolTab should be avoided [see Drug Interactions (7) ] .

5.8 Activation of Mania or Hypomania In patients with bipolar disorder, treating a depressive episode with REMERON/REMERONSolTab or another antidepressant may precipitate a mixed/manic episode.

In controlled clinical trials, patients with bipolar disorder were generally excluded; however, symptoms of mania or hypomania were reported in 0.2% of patients treated with REMERON.

Prior to initiating treatment with REMERON/REMERONSolTab, screen patients for any personal or family history of bipolar disorder, mania, or hypomania.

5.9 Seizures REMERON/REMERONSolTab has not been systematically evaluated in patients with seizure disorders.

In premarketing clinical trials, 1 seizure was reported among the 2796 U.S.

and non-U.S.

patients treated with REMERON.

REMERON/REMERONSolTab should be prescribed with caution in patients with a seizure disorder.

5.10 Elevated Cholesterol and Triglycerides In U.S.

controlled studies, nonfasting cholesterol increases to ≥20% above the upper limits of normal were observed in 15% of patients treated with REMERON, compared to 7% for placebo.

In these same studies, nonfasting triglyceride increases to ≥500 mg/dL were observed in 6% of patients treated with REMERON, compared to 3% for placebo.

5.11 Hyponatremia Hyponatremia may occur as a result of treatment with serotonergic antidepressants, including REMERON/REMERONSolTab.

Cases with serum sodium lower than 110 mmol/L have been reported.

Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls.

Signs and symptoms associated with more severe or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death.

In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

In patients with symptomatic hyponatremia, discontinue REMERON/REMERONSolTab and institute appropriate medical intervention.

Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia [see Use in Specific Populations (8.5) ] .

5.12 Transaminase Elevations Clinically significant ALT (SGPT) elevations (≥3 times the upper limit of the normal range) were observed in 2.0% (8/424) of patients treated with REMERON in a pool of short-term, U.S.

controlled trials, compared to 0.3% (1/328) of placebo patients.

While some patients were discontinued for the ALT increases, in other cases, the enzyme levels returned to normal despite continued REMERON treatment.

REMERON/REMERONSolTab should be used with caution in patients with impaired hepatic function [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] .

5.13 Discontinuation Syndrome There have been reports of adverse reactions upon the discontinuation of REMERON/REMERONSolTab (particularly when abrupt), including but not limited to the following: dizziness, abnormal dreams, sensory disturbances (including paresthesia and electric shock sensations), agitation, anxiety, fatigue, confusion, headache, tremor, nausea, vomiting, and sweating, or other symptoms which may be of clinical significance.

A gradual reduction in the dosage, rather than an abrupt cessation, is recommended [see Dosage and Administration (2.6) ].

5.14 Use in Patients with Concomitant Illness REMERON/REMERONSolTab has not been systematically evaluated or used to any appreciable extent in patients with a recent history of myocardial infarction or other significant heart disease.

REMERON was associated with significant orthostatic hypotension in early clinical pharmacology trials with normal volunteers.

Orthostatic hypotension was infrequently observed in clinical trials with depressed patients [see Adverse Reactions (6.1) ] .

REMERON/REMERONSolTab should be used with caution in patients with known cardiovascular or cerebrovascular disease that could be exacerbated by hypotension (history of myocardial infarction, angina, or ischemic stroke) and conditions that would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medication).

5.15 Risks in Patients with Phenylketonuria Phenylalanine can be harmful to patients with phenylketonuria (PKU).

REMERONSolTab contains phenylalanine, a component of aspartame.

REMERONSolTab contains the following amount of phenylalanine: 2.6 mg in 15 mg orally disintegrating tablet, 5.2 mg in 30 mg orally disintegrating tablet, and 7.8 mg in 45 mg orally disintegrating tablet.

Before prescribing REMERONSolTab to a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including REMERONSolTab.

INFORMATION FOR PATIENTS

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide).

Suicidal Thoughts and Behaviors Advise patients and caregivers to look for the emergence of suicidality, especially early during treatment and when the dosage is adjusted up or down, and instruct them to report such symptoms to the healthcare provider [see Boxed Warning and Warnings and Precautions (5.1) ].

Agranulocytosis Advise patients to contact their physician if they experience fever, chills, sore throat, mucous membrane ulceration, flu-like complaints, or other symptoms that might suggest infection [see Warnings and Precautions (5.2) ].

Serotonin Syndrome Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of REMERON/REMERONSolTab with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, St.

John’s Wort, and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid).

Advise patients to contact their healthcare provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome [see Dosage and Administration (2.4) , Contraindications (4) , Warnings and Precautions (5.3) , Drug Interactions (7) ].

QT Prolongation and Torsades de Pointes Inform patients to consult their physician immediately if they feel faint, lose consciousness, or have heart palpitations [see Warnings and Precautions (5.5) , Drug Interactions (7) , Overdosage (10) ].

Advise patients to inform physicians that they are taking REMERON/REMERONSolTab before any new drug is taken.

Somnolence Advise patients that REMERON/REMERONSolTab may impair judgment, thinking, and particularly, motor skills, because of its prominent sedative effect.

Caution patients about performing activities requiring mental alertness, such as operating hazardous machinery or operating a motor vehicle, until they are reasonably certain that REMERON/REMERONSolTab therapy does not adversely affect their ability to engage in such activities.

[see Warnings and Precautions (5.7) ].

Alcohol Advise patients to avoid alcohol while taking REMERON/REMERONSolTab [see Warnings and Precautions (5.7) , Drug Interactions (7) ].

Activation of Mania/Hypomania Advise patients and their caregivers to observe for signs of activation of mania/hypomania and instruct them to report such symptoms to the healthcare provider [see Warnings and Precautions (5.8) ] .

Discontinuation Syndrome Advise patients not to abruptly discontinue REMERON/REMERONSolTab and to discuss any tapering regimen with their healthcare provider.

Adverse reactions can occur when REMERON/REMERONSolTab is discontinued [see Dosage and Administration (2.6) , Warnings and Precautions (5.13) ].

Allergic Reactions Advise patients to notify their healthcare provider if they develop an allergic reaction such as rash, hives, swelling, or difficulty breathing [see Contraindications (4) , Adverse Reactions (6.2) ] .

Pregnancy Advise patients to notify their physician if they become pregnant or intend to become pregnant during REMERON/REMERONSolTab therapy.

Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to REMERON/REMERONSolTab during pregnancy [see Use in Specific Populations (8.1) ] .

Lactation Advise patients to notify their physician if they are breastfeeding an infant [see Use in Specific Populations (8.2) ].

Angle-Closure Glaucoma Patients should be advised that taking REMERON can cause mild pupillary dilation, which in susceptible individuals, can lead to an episode of angle-closure glaucoma.

Pre-existing glaucoma is almost always open-angle glaucoma because angle-closure glaucoma, when diagnosed, can be treated definitively with iridectomy.

Open-angle glaucoma is not a risk factor for angle-closure glaucoma.

Patients may wish to be examined to determine whether they are susceptible to angle-closure, and have a prophylactic procedure (e.g., iridectomy), if they are susceptible [see Warnings and Precautions (5.4) .] Patients with Phenylketonuria Inform patients with phenylketonuria that REMERONSolTab contains phenylalanine [see Warnings and Precautions (5.15) ].

DOSAGE AND ADMINISTRATION

2 Starting dose: 15-mg once daily; may increase up to maximum recommended dose of 45 mg once daily.

( 2.1 ) Administer orally once daily, preferably in the evening prior to sleep.

( 2.1 ) Administer REMERONSolTab immediately after removal from blister pack.

( 2.2 ) Reduce dose gradually when discontinuing REMERON/REMERONSolTab.

( 2.6 , 5.13 ) 2.1 Recommended Dosage The recommended starting dose of REMERON/REMERONSolTab is 15 mg once daily, administered orally, preferably in the evening prior to sleep.

If patients do not have an adequate response to the initial 15 mg dose, increase the dose up to a maximum of 45 mg per day.

Dose changes should not be made in intervals of less than 1 to 2 weeks to allow sufficient time for evaluation of response to a given dose [see Clinical Pharmacology (12.3) ] .

2.2 Administration of REMERONSolTab The tablet should remain in the blister pack until the patient is ready to take it.

The patient or caregiver should use dry hands to open the blister.

As soon as the blister is opened, the tablet should be removed and placed on the patient’s tongue.

Use REMERONSolTab immediately after removal from its blister; once removed, it cannot be stored.

The whole tablet should be placed on the tongue and allowed to disintegrate without chewing or crushing.

Do not attempt to split the tablet.

The tablet will disintegrate in saliva so that it can be swallowed.

2.3 Screen for Bipolar Disorder Prior to Starting REMERON/REMERONSolTab Prior to initiating treatment with REMERON/REMERONSolTab or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.8) ].

2.4 Switching Patients to or from a Monoamine Oxidase Inhibitor Antidepressant At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of REMERON/REMERONSolTab.

In addition, at least 14 days must elapse after stopping REMERON/REMERONSolTab before starting an MAOI antidepressant [see Contraindications (4) and Warnings and Precautions (5.3) ] .

2.5 Dosage Modifications Due to Drug Interactions Strong CYP3A Inducers An increase in dosage of REMERON/REMERONSolTab may be needed with concomitant strong CYP3A inducer (e.g., carbamazepine, phenytoin, rifampin) use.

Conversely, a decrease in dosage of REMERON/REMERONSolTab may be needed if the CYP3A inducer is discontinued [see Drug Interactions (7) ].

Strong CYP3A Inhibitors A decrease in dosage of REMERON/REMERONSolTab may be needed with concomitant use of strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin).

Conversely, an increase in dosage of REMERON/REMERONSolTab may be needed if the CYP3A4 inhibitor is discontinued [see Drug Interactions (7) ].

Cimetidine A decrease in dosage of REMERON/REMERONSolTab may be needed with concomitant use of cimetidine.

Conversely, an increase in dosage of REMERON/REMERONSolTab may be needed if cimetidine is discontinued [see Drug Interactions (7) ].

2.6 Discontinuation of REMERON/REMERONSolTab Treatment Adverse reactions may occur upon discontinuation or dose reduction of REMERON/REMERONSolTab [see Warnings and Precautions (5.13) ] .

Gradually reduce the dosage of REMERON/REMERONSolTab rather than stopping abruptly whenever possible.

DRUG INTERACTIONS

7 The risks of using olanzapine in combination with other drugs have not been extensively evaluated in systematic studies.

Diazepam: May potentiate orthostatic hypotension.

( 7.1 , 7.2 ) Alcohol: May potentiate orthostatic hypotension.

( 7.1 ) Carbamazepine: Increased clearance of olanzapine.

( 7.1 ) Fluvoxamine: May increase olanzapine levels.

( 7.1 ) Olanzapine and Fluoxetine in Combination: Also refer to the Drug Interactions section of the package insert for Symbyax.

( 7.1 ) CNS Acting Drugs: Caution should be used when taken in combination with other centrally acting drugs and alcohol.

( 7.2 ) Antihypertensive Agents: Enhanced antihypertensive effect.

( 7.2 ) Levodopa and Dopamine Agonists: May antagonize levodopa/dopamine agonists.

( 7.2 ) Other Concomitant Drug Therapy: When using olanzapine in combination with lithium or valproate, refer to the Drug Interactions sections of the package insert for those products.

( 7.2 ) 7.1 Potential for Other Drugs to Affect Olanzapine Diazepam — The co-administration of diazepam with olanzapine potentiated the orthostatic hypotension observed with olanzapine [ see Drug Interactions (7.2) ] .

Cimetidine and Antacids — Single doses of cimetidine (800 mg) or aluminum- and magnesium-containing antacids did not affect the oral bioavailability of olanzapine.

Inducers of CYP1A2 — Carbamazepine therapy (200 mg bid) causes an approximately 50% increase in the clearance of olanzapine.

This increase is likely due to the fact that carbamazepine is a potent inducer of CYP1A2 activity.

Higher daily doses of carbamazepine may cause an even greater increase in olanzapine clearance.

Alcohol — Ethanol (45 mg/70 kg single dose) did not have an effect on olanzapine pharmacokinetics.

The co-administration of alcohol (i.e., ethanol) with olanzapine potentiated the orthostatic hypotension observed with olanzapine [see Drug Interactions (7.2)].

Inhibitors of CYP1A2 Fluvoxamine: Fluvoxamine, a CYP1A2 inhibitor, decreases the clearance of olanzapine.

This results in a mean increase in olanzapine C max following fluvoxamine of 54% in female nonsmokers and 77% in male smokers.

The mean increase in olanzapine AUC is 52% and 108%, respectively.

Lower doses of olanzapine should be considered in patients receiving concomitant treatment with fluvoxamine.

Inhibitors of CYP2D6 Fluoxetine: Fluoxetine (60 mg single dose or 60 mg daily dose for 8 days) causes a small (mean 16%) increase in the maximum concentration of olanzapine and a small (mean 16%) decrease in olanzapine clearance.

The magnitude of the impact of this factor is small in comparison to the overall variability between individuals, and therefore dose modification is not routinely recommended.

When using olanzapine and fluoxetine in combination, also refer to the Drug Interactions section of the package insert for Symbyax.

Warfarin — Warfarin (20 mg single dose) did not affect olanzapine pharmacokinetics [ see Drug Interactions (7.2) ] .

Inducers of CYP1A2 or Glucuronyl Transferase — Omeprazole and rifampin may cause an increase in olanzapine clearance.

Charcoal — The administration of activated charcoal (1 g) reduced the C max and AUC of oral olanzapine by about 60%.

As peak olanzapine levels are not typically obtained until about 6 hours after dosing, charcoal may be a useful treatment for olanzapine overdose.

Anticholinergic Drugs — Concomitant treatment with olanzapine and other drugs with anticholinergic activity can increase the risk for severe gastrointestinal adverse reactions related to hypomotility.

Olanzapine should be used with caution in patients receiving medications having anticholinergic (antimuscarinic) effects [see Warnings and Precautions (5.14)] .

7.2 Potential for Olanzapine to Affect Other Drugs CNS Acting Drugs — Given the primary CNS effects of olanzapine, caution should be used when olanzapine is taken in combination with other centrally acting drugs and alcohol.

Antihypertensive Agents — Olanzapine, because of its potential for inducing hypotension, may enhance the effects of certain antihypertensive agents.

Levodopa and Dopamine Agonists — Olanzapine may antagonize the effects of levodopa and dopamine agonists.

Lithium — Multiple doses of olanzapine (10 mg for 8 days) did not influence the kinetics of lithium.

Therefore, concomitant olanzapine administration does not require dosage adjustment of lithium [see Warnings and Precautions (5.16)] .

Valproate — Olanzapine (10 mg daily for 2 weeks) did not affect the steady state plasma concentrations of valproate.

Therefore, concomitant olanzapine administration does not require dosage adjustment of valproate [see Warnings and Precautions (5.16)].

Effect of Olanzapine on Drug Metabolizing Enzymes — In vitro studies utilizing human liver microsomes suggest that olanzapine has little potential to inhibit CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A.

Thus, olanzapine is unlikely to cause clinically important drug interactions mediated by these enzymes.

Imipramine — Single doses of olanzapine did not affect the pharmacokinetics of imipramine or its active metabolite desipramine.

Warfarin — Single doses of olanzapine did not affect the pharmacokinetics of warfarin [see Drug Interactions (7.1)] .

Diazepam — Olanzapine did not influence the pharmacokinetics of diazepam or its active metabolite N-desmethyldiazepam.

However, diazepam co-administered with olanzapine increased the orthostatic hypotension observed with either drug given alone [see Drug Interactions (7.1)] .

Alcohol — Multiple doses of olanzapine did not influence the kinetics of ethanol [see Drug Interactions (7.1)] .

Biperiden — Multiple doses of olanzapine did not influence the kinetics of biperiden.

Theophylline — Multiple doses of olanzapine did not affect the pharmacokinetics of theophylline or its metabolites.

OVERDOSAGE

10 10.1 Human Experience In premarketing trials involving more than 3100 patients and/or normal subjects, accidental or intentional acute overdosage of olanzapine was identified in 67 patients.

In the patient taking the largest identified amount, 300 mg, the only symptoms reported were drowsiness and slurred speech.

In the limited number of patients who were evaluated in hospitals, including the patient taking 300 mg, there were no observations indicating an adverse change in laboratory analytes or ECG.

Vital signs were usually within normal limits following overdoses.

In postmarketing reports of overdose with olanzapine alone, symptoms have been reported in the majority of cases.

In symptomatic patients, symptoms with ≥10% incidence included agitation/aggressiveness, dysarthria, tachycardia, various extrapyramidal symptoms, and reduced level of consciousness ranging from sedation to coma.

Among less commonly reported symptoms were the following potentially medically serious reactions: aspiration, cardiopulmonary arrest, cardiac arrhythmias (such as supraventricular tachycardia and 1 patient experiencing sinus pause with spontaneous resumption of normal rhythm), delirium, possible neuroleptic malignant syndrome, respiratory depression/arrest, convulsion, hypertension, and hypotension.

Reports of fatality in association with overdose of olanzapine alone have been received.

In 1 case of death, the amount of acutely ingested olanzapine was reported to be possibly as low as 450 mg of oral olanzapine; however, in another case, a patient was reported to survive an acute olanzapine ingestion of approximately 2 g of oral olanzapine.

10.2 Management of Overdose There is no specific antidote to an overdose of olanzapine.

The possibility of multiple drug involvement should be considered.

Establish and maintain an airway and ensure adequate oxygenation and ventilation.

Cardiovascular monitoring should commence immediately and should include continuous electrocardiographic monitoring to detect possible arrhythmias.

Contact a Certified Poison Control Center for the most up to date information on the management of overdosage (1-800-222-1222).

For specific information about overdosage with lithium or valproate, refer to the Overdosage section of the prescribing information for those products.

For specific information about overdosage with olanzapine and fluoxetine in combination, refer to the Overdosage section of the Symbyax prescribing information.

CLINICAL STUDIES

14 When using olanzapine and fluoxetine in combination, also refer to the Clinical Studies section of the package insert for Symbyax.

14.1 Schizophrenia Adults The efficacy of oral olanzapine in the treatment of schizophrenia was established in 2 short-term (6-week) controlled trials of adult inpatients who met DSM III-R criteria for schizophrenia.

A single haloperidol arm was included as a comparative treatment in 1 of the 2 trials, but this trial did not compare these 2 drugs on the full range of clinically relevant doses for both.

Several instruments were used for assessing psychiatric signs and symptoms in these studies, among them the Brief Psychiatric Rating Scale (BPRS), a multi-item inventory of general psychopathology traditionally used to evaluate the effects of drug treatment in schizophrenia.

The BPRS psychosis cluster (conceptual disorganization, hallucinatory behavior, suspiciousness, and unusual thought content) is considered a particularly useful subset for assessing actively psychotic schizophrenic patients.

A second traditional assessment, the Clinical Global Impression (CGI), reflects the impression of a skilled observer, fully familiar with the manifestations of schizophrenia, about the overall clinical state of the patient.

In addition, 2 more recently developed scales were employed; these included the 30-item Positive and Negative Symptoms Scale (PANSS), in which are embedded the 18 items of the BPRS, and the Scale for Assessing Negative Symptoms (SANS).

The trial summaries below focus on the following outcomes: PANSS total and/or BPRS total; BPRS psychosis cluster; PANSS negative subscale or SANS; and CGI Severity.

The results of the trials follow: (1) In a 6-week, placebo-controlled trial (n=149) involving 2 fixed olanzapine doses of 1 and 10 mg/day (once daily schedule), olanzapine, at 10 mg/day (but not at 1 mg/day), was superior to placebo on the PANSS total score (also on the extracted BPRS total), on the BPRS psychosis cluster, on the PANSS Negative subscale, and on CGI Severity.

(2) In a 6-week, placebo-controlled trial (n=253) involving 3 fixed dose ranges of olanzapine (5 ± 2.5 mg/day, 10 ± 2.5 mg/day, and 15 ± 2.5 mg/day) on a once daily schedule, the 2 highest olanzapine dose groups (actual mean doses of 12 and 16 mg/day, respectively) were superior to placebo on BPRS total score, BPRS psychosis cluster, and CGI severity score; the highest olanzapine dose group was superior to placebo on the SANS.

There was no clear advantage for the high-dose group over the medium-dose group.

(3) In a longer-term trial, adult outpatients (n=326) who predominantly met DSM-IV criteria for schizophrenia and who remained stable on olanzapine during open-label treatment for at least 8 weeks were randomized to continuation on their current olanzapine doses (ranging from 10 to 20 mg/day) or to placebo.

The follow-up period to observe patients for relapse, defined in terms of increases in BPRS positive symptoms or hospitalization, was planned for 12 months, however, criteria were met for stopping the trial early due to an excess of placebo relapses compared to olanzapine relapses, and olanzapine was superior to placebo on time to relapse, the primary outcome for this study.

Thus, olanzapine was more effective than placebo at maintaining efficacy in patients stabilized for approximately 8 weeks and followed for an observation period of up to 8 months.

Examination of population subsets (race and gender) did not reveal any differential responsiveness on the basis of these subgroupings.

Adolescents The efficacy of oral olanzapine in the acute treatment of schizophrenia in adolescents (ages 13 to 17 years) was established in a 6-week double-blind, placebo-controlled, randomized trial of inpatients and outpatients with schizophrenia (n=107) who met diagnostic criteria according to DSM-IV-TR and confirmed by the Kiddie Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime Version (K-SADS-PL).

The primary rating instrument used for assessing psychiatric signs and symptoms in this trial was the Anchored Version of the Brief Psychiatric Rating Scale for Children (BPRS-C) total score.

In this flexible-dose trial, olanzapine 2.5 to 20 mg/day (mean modal dose 12.5 mg/day, mean dose of 11.1 mg/day) was more effective than placebo in the treatment of adolescents diagnosed with schizophrenia, as supported by the statistically significantly greater mean reduction in BPRS-C total score for patients in the olanzapine treatment group than in the placebo group.

While there is no body of evidence available to answer the question of how long the adolescent patient treated with olanzapine should be maintained, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients.

It is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission.

Patients should be periodically reassessed to determine the need for maintenance treatment.

14.2 Bipolar I Disorder (Manic or Mixed Episodes) Adults Monotherapy — The efficacy of oral olanzapine in the treatment of manic or mixed episodes was established in 2 short-term (one 3-week and one 4-week) placebo-controlled trials in adult patients who met the DSM-IV criteria for bipolar I disorder with manic or mixed episodes.

These trials included patients with or without psychotic features and with or without a rapid-cycling course.

The primary rating instrument used for assessing manic symptoms in these trials was the Young Mania Rating Scale (Y-MRS), an 11-item clinician-rated scale traditionally used to assess the degree of manic symptomatology (irritability, disruptive/aggressive behavior, sleep, elevated mood, speech, increased activity, sexual interest, language/thought disorder, thought content, appearance, and insight) in a range from 0 (no manic features) to 60 (maximum score).

The primary outcome in these trials was change from baseline in the Y-MRS total score.

The results of the trials follow: (1) In one 3-week placebo-controlled trial (n=67) which involved a dose range of olanzapine (5 to 20 mg/day, once daily, starting at 10 mg/day), olanzapine was superior to placebo in the reduction of Y-MRS total score.

In an identically designed trial conducted simultaneously with the first trial, olanzapine demonstrated a similar treatment difference, but possibly due to sample size and site variability, was not shown to be superior to placebo on this outcome.

(2) In a 4-week placebo-controlled trial (n=115) which involved a dose range of olanzapine (5 to 20 mg/day, once daily, starting at 15 mg/day), olanzapine was superior to placebo in the reduction of Y-MRS total score.

(3) In another trial, 361 patients meeting DSM-IV criteria for a manic or mixed episode of bipolar I disorder who had responded during an initial open-label treatment phase for about 2 weeks, on average, to olanzapine 5 to 20 mg/day were randomized to either continuation of olanzapine at their same dose (n=225) or to placebo (n=136), for observation of relapse.

Approximately 50% of the patients had discontinued from the olanzapine group by day 59 and 50% of the placebo group had discontinued by day 23 of double-blind treatment.

Response during the open-label phase was defined by having a decrease of the Y-MRS total score to ≤12 and HAM-D 21 to ≤8.

Relapse during the double-blind phase was defined as an increase of the Y-MRS or HAM-D 21 total score to ≥15, or being hospitalized for either mania or depression.

In the randomized phase, patients receiving continued olanzapine experienced a significantly longer time to relapse.

Adjunct to Lithium or Valproate — The efficacy of oral olanzapine with concomitant lithium or valproate in the treatment of manic or mixed episodes was established in 2 controlled trials in patients who met the DSM-IV criteria for bipolar I disorder with manic or mixed episodes.

These trials included patients with or without psychotic features and with or without a rapid-cycling course.

The results of the trials follow: (1) In one 6-week placebo-controlled combination trial, 175 outpatients on lithium or valproate therapy with inadequately controlled manic or mixed symptoms (Y-MRS ≥16) were randomized to receive either olanzapine or placebo, in combination with their original therapy.

Olanzapine (in a dose range of 5 to 20 mg/day, once daily, starting at 10 mg/day) combined with lithium or valproate (in a therapeutic range of 0.6 mEq/L to 1.2 mEq/L or 50 mcg/mL to 125 mcg/mL, respectively) was superior to lithium or valproate alone in the reduction of Y-MRS total score.

(2) In a second 6-week placebo-controlled combination trial, 169 outpatients on lithium or valproate therapy with inadequately controlled manic or mixed symptoms (Y-MRS ≥16) were randomized to receive either olanzapine or placebo, in combination with their original therapy.

Olanzapine (in a dose range of 5 to 20 mg/day, once daily, starting at 10 mg/day) combined with lithium or valproate (in a therapeutic range of 0.6 mEq/L to 1.2 mEq/L or 50 mcg/mL to 125 mcg/mL, respectively) was superior to lithium or valproate alone in the reduction of Y-MRS total score.

Adolescents Acute Monotherapy — The efficacy of oral olanzapine in the treatment of acute manic or mixed episodes in adolescents (ages 13 to 17 years) was established in a 3-week, double-blind, placebo-controlled, randomized trial of adolescent inpatients and outpatients who met the diagnostic criteria for manic or mixed episodes associated with bipolar I disorder (with or without psychotic features) according to the DSM-IV-TR (n=161).

Diagnosis was confirmed by the K-SADS-PL.

The primary rating instrument used for assessing manic symptoms in this trial was the Adolescent Structured Young-Mania Rating Scale (Y-MRS) total score.

In this flexible-dose trial, olanzapine 2.5 to 20 mg/day (mean modal dose 10.7 mg/day, mean dose of 8.9 mg/day) was more effective than placebo in the treatment of adolescents with manic or mixed episodes associated with bipolar I disorder, as supported by the statistically significantly greater mean reduction in Y-MRS total score for patients in the olanzapine treatment group than in the placebo group.

While there is no body of evidence available to answer the question of how long the adolescent patient treated with olanzapine should be maintained, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients.

It is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission.

Patients should be periodically reassessed to determine the need for maintenance treatment.

GERIATRIC USE

8.5 Geriatric Use Of the 2500 patients in premarketing clinical studies with oral olanzapine, 11% (263) were 65 years of age or over.

In patients with schizophrenia, there was no indication of any different tolerability of olanzapine in the elderly compared to younger patients.

Studies in elderly patients with dementia-related psychosis have suggested that there may be a different tolerability profile in this population compared to younger patients with schizophrenia.

Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo.

In placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis, there was a higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) in patients treated with olanzapine compared to patients treated with placebo.

In 5 placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis (n=1184), the following adverse reactions were reported in olanzapine-treated patients at an incidence of at least 2% and significantly greater than placebo-treated patients: falls, somnolence, peripheral edema, abnormal gait, urinary incontinence, lethargy, increased weight, asthenia, pyrexia, pneumonia, dry mouth and visual hallucinations.

The rate of discontinuation due to adverse reactions was greater with olanzapine than placebo (13% vs 7%).

Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo.

Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.1), and Patient Counseling Information (17)].

Olanzapine is not approved for the treatment of patients with dementia-related psychosis.

Also, the presence of factors that might decrease pharmacokinetic clearance or increase the pharmacodynamic response to olanzapine should lead to consideration of a lower starting dose for any geriatric patient [see Boxed Warning, Dosage and Administration (2.1), and Warnings and Precautions (5.1)] .

Clinical studies of olanzapine and fluoxetine in combination did not include sufficient numbers of patients ≥65 years of age to determine whether they respond differently from younger patients.

MECHANISM OF ACTION

12.1 Mechanism of Action The mechanism of action of olanzapine, in the listed indications is unclear.

However, the efficacy of olanzapine in schizophrenia could be mediated through a combination of dopamine and serotonin type 2 (5HT 2 ) antagonism.

When deciding among the alternative treatments available for adolescents, clinicians should consider the increased potential (in adolescents as compared with adults) for weight gain and dyslipidemia.

Clinicians should consider the potential long-term risks when prescribing to adolescents, and in many cases this may lead them to consider prescribing other drugs first in adolescents [see Warnings and Precautions (5.5) ] .

1.2 Bipolar I Disorder (Manic or Mixed Episodes) Monotherapy — Olanzapine orally disintegrating tablets are indicated for the acute treatment of manic or mixed episodes associated with bipolar I disorder and maintenance treatment of bipolar I disorder.

Efficacy was established in three clinical trials in adult patients with manic or mixed episodes of bipolar I disorder: two 3- to 4-week trials and one monotherapy maintenance trial.

In adolescent patients with manic or mixed episodes associated with bipolar I disorder (ages 13 to 17), efficacy was established in one 3-week trial [ see Clinical Studies (14.2)] .

When deciding among the alternative treatments available for adolescents, clinicians should consider the increased potential (in adolescents as compared with adults) for weight gain and dyslipidemia.

Clinicians should consider the potential long-term risks when prescribing to adolescents, and in many cases this may lead them to consider prescribing other drugs first in adolescents [see Warnings and Precautions (5.5) ] .

Adjunctive Therapy to Lithium or Valproate — Olanzapine orally disintegrating tablets are indicated for the treatment of manic or mixed episodes associated with bipolar I disorder as an adjunct to lithium or valproate.

Efficacy was established in two 6-week clinical trials in adults.

The effectiveness of adjunctive therapy for longer-term use has not been systematically evaluated in controlled trials [see Clinical Studies (14.2)] .

1.3 Special Considerations in Treating Pediatric Schizophrenia and Bipolar I Disorder Pediatric schizophrenia and bipolar I disorder are serious mental disorders; however, diagnosis can be challenging.

For pediatric schizophrenia, symptom profiles can be variable, and for bipolar I disorder, pediatric patients may have variable patterns of periodicity of manic or mixed symptoms.

It is recommended that medication therapy for pediatric schizophrenia and bipolar I disorder be initiated only after a thorough diagnostic evaluation has been performed and careful consideration given to the risks associated with medication treatment.

Medication treatment for both pediatric schizophrenia and bipolar I disorder should be part of a total treatment program that often includes psychological, educational and social interventions.

1.5 Olanzapine and Fluoxetine in Combination: Depressive Episodes Associated with Bipolar I Disorder Olanzapine and fluoxetine in combination are indicated for the treatment of depressive episodes associated with bipolar I disorder, based on clinical studies.

When using olanzapine and fluoxetine in combination, refer to the Clinical Studies section of the package insert for Symbyax.

Olanzapine orally disintegrating tablets monotherapy is not indicated for the treatment of depressive episodes associated with bipolar I disorder.

1.6 Olanzapine and Fluoxetine in Combination: Treatment Resistant Depression Oral Olanzapine and fluoxetine in combination is indicated for the treatment of treatment resistant depression (major depressive disorder in patients who do not respond to 2 separate trials of different antidepressants of adequate dose and duration in the current episode), based on clinical studies in adult patients.

When using olanzapine and fluoxetine in combination, refer to the Clinical Studies section of the package insert for Symbyax.

Olanzapine orally disintegrating tablets monotherapy is not indicated for the treatment of treatment resistant depression.

PEDIATRIC USE

8.4 Pediatric Use The safety and effectiveness of oral olanzapine in the treatment of schizophrenia and manic or mixed episodes associated with bipolar I disorder were established in short-term studies in adolescents (ages 13 to 17 years).

Use of olanzapine in adolescents is supported by evidence from adequate and well-controlled studies of olanzapine in which 268 adolescents received olanzapine in a range of 2.5 to 20 mg/day [see Clinical Studies (14.1, 14.2)].

Recommended starting dose for adolescents is lower than that for adults [see Dosage and Administration (2.1, 2.2)] .

Compared to patients from adult clinical trials, adolescents were likely to gain more weight, experience increased sedation, and have greater increases in total cholesterol, triglycerides, LDL cholesterol, prolactin and hepatic aminotransferase levels [see Warnings and Precautions (5.5, 5.15, 5.17) and Adverse Reactions (6.1)] .

When deciding among the alternative treatments available for adolescents, clinicians should consider the increased potential (in adolescents as compared with adults) for weight gain and dyslipidemia.

Clinicians should consider the potential long-term risks when prescribing to adolescents, and in many cases this may lead them to consider prescribing other drugs first in adolescents [see Indications and Usage (1.1, 1.2)] .

Safety and effectiveness of olanzapine in children <13 years of age have not been established [see Patient Counseling Information (17)] .

Safety and efficacy of olanzapine and fluoxetine in combination in children and adolescents (10 to 17 years of age) have been established for the acute treatment of depressive episodes associated with bipolar I disorder.

Safety and effectiveness of olanzapine and fluoxetine in combination in children < 10 years of age have not been established.

PREGNANCY

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including olanzapine, during pregnancy.

Healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.

Risk Summary Neonates exposed to antipsychotic drugs, including olanzapine, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see Clinical Considerations).

Overall available data from published epidemiologic studies of pregnant women exposed to olanzapine have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data).

There are risks to the mother associated with untreated schizophrenia or bipolar I disorder and with exposure to antipsychotics, including olanzapine, during pregnancy (see Clinical Considerations).

Olanzapine was not teratogenic when administered orally to pregnant rats and rabbits at doses that are 9- and 30-times the daily oral maximum recommended human dose (MRHD), based on mg/m 2 body surface area; some fetal toxicities were observed at these doses ( see Data ).

The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown.

All pregnancies have a background risk of birth defects, loss, or other adverse outcomes.

In the U.S.

general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Clinical Considerations Disease-associated maternal and embryo/fetal risk There is a risk to the mother from untreated schizophrenia or bipolar I disorder, including increased risk of relapse, hospitalization, and suicide.

Schizophrenia and bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth.

It is not known if this is a direct result of the illness or other comorbid factors.

Fetal/Neonatal adverse reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including olanzapine, during the third trimester of pregnancy.

These symptoms have varied in severity.

Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately.

Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization.

Data Human Data Placental passage has been reported in published study reports; however, the placental passage ratio was highly variable ranging between 7% to 167% at birth following exposure during pregnancy.

The clinical relevance of this finding is unknown.

Published data from observational studies, birth registries, and case reports that have evaluated the use of atypical antipsychotics during pregnancy do not establish an increased risk of major birth defects.

A retrospective cohort study from a Medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk for major birth defects.

Animal Data In oral reproduction studies in rats at doses up to 18 mg/kg/day and in rabbits at doses up to 30 mg/kg/day (9 and 30 times the daily oral MRHD based on mg/m 2 body surface area, respectively), no evidence of teratogenicity was observed.

In an oral rat teratology study, early resorptions and increased numbers of nonviable fetuses were observed at a dose of 18 mg/kg/day (9 times the daily oral MRHD based on mg/m 2 body surface area), and gestation was prolonged at 10 mg/kg/day (5 times the daily oral MRHD based on mg/m 2 body surface area).

In an oral rabbit teratology study, fetal toxicity manifested as increased resorptions and decreased fetal weight, occurred at a maternally toxic dose of 30 mg/kg/day (30 times the daily oral MRHD based on mg/m 2 body surface area).

BOXED WARNING

WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients.

Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group.

Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature.

Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality.

The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear .

Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Warnings and Precautions (5.1) , Use in Specific Populations (8.5 ), and Patient Counseling Information (17) ] .

When using olanzapine and fluoxetine in combination, also refer to the Boxed Warning section of the package insert for Symbyax.

WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS See full prescribing information for complete boxed warning.

Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

Olanzapine is not approved for the treatment of patients with dementia-related psychosis.

( 5.1 5) Use in Combination with Fluoxetine, Lithium or Valproate: Also refer to the package inserts for Symbyax, lithium, or valproate.

( 5.16 ) Laboratory Tests: Monitor fasting blood glucose and lipid profiles at the beginning of, and periodically during, treatment.

( 5.1 7) 5.1 Elderly Patients with Dementia-Related Psychosis Increased Mortality — Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Use in Specific Populations (8.5) , and Patient Counseling Information (17)] .

In placebo-controlled clinical trials of elderly patients with dementia-related psychosis, the incidence of death in olanzapine-treated patients was significantly greater than placebo-treated patients (3.5% vs 1.5%, respectively).

Cerebrovascular Adverse Events (CVAE), Including Stroke — Cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, were reported in patients in trials of olanzapine in elderly patients with dementia-related psychosis.

In placebo-controlled trials, there was a significantly higher incidence of cerebrovascular adverse events in patients treated with olanzapine compared to patients treated with placebo.

Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning and Patient Counseling Information (17 )] .

5.2 Suicide The possibility of a suicide attempt is inherent in schizophrenia and in bipolar I disorder, and close supervision of high-risk patients should accompany drug therapy.

Prescriptions for olanzapine should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce the risk of overdose.

5.3 Neuroleptic Malignant Syndrome (NMS) A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with administration of antipsychotic drugs, including olanzapine.

Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac dysrhythmia).

Additional signs may include elevated creatinine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.

The diagnostic evaluation of patients with this syndrome is complicated.

In arriving at a diagnosis, it is important to exclude cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS).

Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system pathology.

The management of NMS should include: 1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy; 2) intensive symptomatic treatment and medical monitoring; and 3) treatment of any concomitant serious medical problems for which specific treatments are available.

There is no general agreement about specific pharmacological treatment regimens for NMS.

If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered.

The patient should be carefully monitored, since recurrences of NMS have been reported [see Patient Counseling Information (17) ] .

5.4 Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported with olanzapine exposure.

DRESS may present with a cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, fever, and/or lymphadenopathy with systemic complications such as hepatitis, nephritis, pneumonitis, myocarditis, and/or pericarditis.

DRESS is sometimes fatal.

Discontinue olanzapine if DRESS is suspected [ see Patient Counseling Information (17 )] .

5.5 Metabolic Changes Atypical antipsychotic drugs have been associated with metabolic changes including hyperglycemia, dyslipidemia, and weight gain.

Metabolic changes may be associated with increased cardiovascular/cerebrovascular risk.

Olanzapine’s specific metabolic profile is presented below.

Hyperglycemia and Diabetes Mellitus Healthcare providers should consider the risks and benefits when prescribing olanzapine to patients with an established diagnosis of diabetes mellitus, or having borderline increased blood glucose level (fasting 100 to 126 mg/dL, nonfasting 140 to 200 mg/dL).

Patients taking olanzapine should be monitored regularly for worsening of glucose control.

Patients starting treatment with olanzapine should undergo fasting blood glucose testing at the beginning of treatment and periodically during treatment.

Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness.

Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing.

In some cases, hyperglycemia has resolved when the atypical antipsychotic was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the suspect drug [see Patient Counseling Information (17) ] .

Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics including olanzapine.

Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population.

Epidemiological studies suggest an increased risk of treatment-emergent hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics.

While relative risk estimates are inconsistent, the association between atypical antipsychotics and increases in glucose levels appears to fall on a continuum and olanzapine appears to have a greater association than some other atypical antipsychotics.

Mean increases in blood glucose have been observed in patients treated (median exposure of 9.2 months) with olanzapine in phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE).

The mean increase of serum glucose (fasting and nonfasting samples) from baseline to the average of the 2 highest serum concentrations was 15.0 mg/dL.

In a study of healthy volunteers, subjects who received olanzapine (N=22) for 3 weeks had a mean increase compared to baseline in fasting blood glucose of 2.3 mg/dL.

Placebo-treated subjects (N=19) had a mean increase in fasting blood glucose compared to baseline of 0.34 mg/dL.

Olanzapine Monotherapy in Adults — In an analysis of 5 placebo-controlled adult olanzapine monotherapy studies with a median treatment duration of approximately 3 weeks, olanzapine was associated with a greater mean change in fasting glucose levels compared to placebo (2.76 mg/dL versus 0.17 mg/dL).

The difference in mean changes between olanzapine and placebo was greater in patients with evidence of glucose dysregulation at baseline (patients diagnosed with diabetes mellitus or related adverse reactions, patients treated with anti-diabetic agents, patients with a baseline random glucose level ≥200 mg/dL, and/or a baseline fasting glucose level ≥126 mg/dL).

Olanzapine-treated patients had a greater mean HbA 1c increase from baseline of 0.04% (median exposure 21 days), compared to a mean HbA 1c decrease of 0.06% in placebo-treated subjects (median exposure 17 days).

In an analysis of 8 placebo-controlled studies (median treatment exposure 4-5 weeks), 6.1% of olanzapine-treated subjects (N=855) had treatment-emergent glycosuria compared to 2.8% of placebo-treated subjects (N=599).

Table 2 shows short-term and long-term changes in fasting glucose levels from adult olanzapine monotherapy studies.

Table 2: Changes in Fasting Glucose Levels from Adult Olanzapine Monotherapy Studies Up to 12 weeks exposure At least 48 weeks exposure Laboratory Analyte Category Change (at least once) from Baseline Treatment Arm N Patients N Patients Fasting Glucose Normal to High (<100 mg/dL to ≥126 mg/dL) Olanzapine 543 2.2% 345 12.8% Placebo 293 3.4% NA a NA a Borderline to High (≥100 mg/dL and <126 mg/dL to ≥126 mg/dL) Olanzapine 178 17.4% 127 26% Placebo 96 11.5% NA a NA a a Not Applicable.

The mean change in fasting glucose for patients exposed at least 48 weeks was 4.2 mg/dL (N=487).

In analyses of patients who completed 9 to 12 months of olanzapine therapy, mean change in fasting and nonfasting glucose levels continued to increase over time.

Olanzapine Monotherapy in Adolescents — The safety and efficacy of olanzapine have not been established in patients under the age of 13 years.

In an analysis of 3 placebo-controlled olanzapine monotherapy studies of adolescent patients, including those with schizophrenia (6 weeks) or bipolar I disorder (manic or mixed episodes) (3 weeks), olanzapine was associated with a greater mean change from baseline in fasting glucose levels compared to placebo (2.68 mg/dL versus -2.59 mg/dL).

The mean change in fasting glucose for adolescents exposed at least 24 weeks was 3.1 mg/dL (N=121).

Table 3 shows short-term and long-term changes in fasting blood glucose from adolescent olanzapine monotherapy studies.

Dyslipidemia Undesirable alterations in lipids have been observed with olanzapine use.

Clinical monitoring, including baseline and periodic follow-up lipid evaluations in patients using olanzapine, is recommended [see Patient Counseling Information (17)].

Clinically significant, and sometimes very high (>500 mg/dL), elevations in triglyceride levels have been observed with olanzapine use.

Modest mean increases in total cholesterol have also been seen with olanzapine use.

Olanzapine Monotherapy in Adults — In an analysis of 5 placebo-controlled olanzapine monotherapy studies with treatment duration up to 12 weeks, olanzapine-treated patients had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.3 mg/dL, 3.0 mg/dL, and 20.8 mg/dL respectively compared to decreases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 6.1 mg/dL, 4.3 mg/dL, and 10.7 mg/dL for placebo-treated patients.

For fasting HDL cholesterol, no clinically meaningful differences were observed between olanzapine-treated patients and placebo-treated patients.

Mean increases in fasting lipid values (total cholesterol, LDL cholesterol, and triglycerides) were greater in patients without evidence of lipid dysregulation at baseline, where lipid dysregulation was defined as patients diagnosed with dyslipidemia or related adverse reactions, patients treated with lipid lowering agents, or patients with high baseline lipid levels.

In long-term studies (at least 48 weeks), patients had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.6 mg/dL, 2.5 mg/dL, and 18.7 mg/dL, respectively, and a mean decrease in fasting HDL cholesterol of 0.16 mg/dL.

In an analysis of patients who completed 12 months of therapy, the mean nonfasting total cholesterol did not increase further after approximately 4-6 months.

The proportion of patients who had changes (at least once) in total cholesterol, LDL cholesterol or triglycerides from normal or borderline to high, or changes in HDL cholesterol from normal or borderline to low, was greater in long-term studies (at least 48 weeks) as compared with short-term studies.

In phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE), over a median exposure of 9.2 months, the mean increase in triglycerides in patients taking olanzapine was 40.5 mg/dL.

In phase 1 of CATIE, the mean increase in total cholesterol was 9.4 mg/dL.

Olanzapine Monotherapy in Adolescents — The safety and efficacy of olanzapine have not been established in patients under the age of 13 years.

In an analysis of 3 placebo-controlled olanzapine monotherapy studies of adolescents, including those with schizophrenia (6 weeks) or bipolar I disorder (manic or mixed episodes) (3 weeks), olanzapine-treated adolescents had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 12.9 mg/dL, 6.5 mg/dL, and 28.4 mg/dL, respectively, compared to increases from baseline in mean fasting total cholesterol and LDL cholesterol of 1.3 mg/dL and 1.0 mg/dL, and a decrease in triglycerides of 1.1 mg/dL for placebo-treated adolescents.

For fasting HDL cholesterol, no clinically meaningful differences were observed between olanzapine-treated adolescents and placebo-treated adolescents.

In long-term studies (at least 24 weeks), adolescents had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.5 mg/dL, 5.4 mg/dL, and 20.5 mg/dL, respectively, and a mean decrease in fasting HDL cholesterol of 4.5 mg/dL.

Table 5 shows categorical changes in fasting lipids values in adolescents.

Weight Gain Potential consequences of weight gain should be considered prior to starting olanzapine.

Patients receiving olanzapine should receive regular monitoring of weight [see Patient Counseling Information (17) ] .

Olanzapine Monotherapy in Adults — In an analysis of 13 placebo-controlled olanzapine monotherapy studies, olanzapine-treated patients gained an average of 2.6 kg (5.7 lb) compared to an average 0.3 kg (0.6 lb) weight loss in placebo-treated patients with a median exposure of 6 weeks; 22.2% of olanzapine-treated patients gained at least 7% of their baseline weight, compared to 3% of placebo-treated patients, with a median exposure to event of 8 weeks; 4.2% of olanzapine-treated patients gained at least 15% of their baseline weight, compared to 0.3% of placebo-treated patients, with a median exposure to event of 12 weeks.

Clinically significant weight gain was observed across all baseline Body Mass Index (BMI) categories.

Discontinuation due to weight gain occurred in 0.2% of olanzapine-treated patients and in 0% of placebo-treated patients.

In long-term studies (at least 48 weeks), the mean weight gain was 5.6 kg (12.3 lb) (median exposure of 573 days, N=2021).

The percentages of patients who gained at least 7%, 15%, or 25% of their baseline body weight with long-term exposure were 64%, 32%, and 12%, respectively.

Discontinuation due to weight gain occurred in 0.4% of olanzapine-treated patients following at least 48 weeks of exposure.

Table 6 includes data on adult weight gain with olanzapine pooled from 86 clinical trials.

The data in each column represent data for those patients who completed treatment periods of the durations specified.

Table 6: Weight Gain with Olanzapine Use in Adults Amount Gained kg (lb) 6 Weeks (N=7465) (%) 6 Months (N=4162) (%) 12 Months (N=1345) (%) 24 Months (N=474) (%) 36 Months (N=147) (%) ≤0 26.2 24.3 20.8 23.2 17 0 to ≤5 (0-11 lb) 57 36 26 23.4 25.2 >5 to ≤10 (11-22 lb) 14.9 24.6 24.2 24.1 18.4 >10 to ≤15 (22-33 lb) 1.8 10.9 14.9 11.4 17 >15 to ≤20 (33-44 lb) 0.1 3.1 8.6 9.3 11.6 >20 to ≤25 (44-55 lb) 0 0.9 3.3 5.1 4.1 >25 to ≤30 (55-66 lb) 0 0.2 1.4 2.3 4.8 >30 (>66 lb) 0 0.1 0.8 1.2 2 Dose group differences with respect to weight gain have been observed.

In a single 8-week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200) and 40 (N=200) mg/day of oral olanzapine in adult patients with schizophrenia or schizoaffective disorder, mean baseline to endpoint increase in weight (10 mg/day: 1.9 kg; 20 mg/day: 2.3 kg; 40 mg/day: 3 kg) was observed with significant differences between 10 vs 40 mg/day.

Olanzapine Monotherapy in Adolescents – The safety and efficacy of olanzapine have not been established in patients under the age of 13 years.

Mean increase in weight in adolescents was greater than in adults.

In 4 placebo-controlled trials, discontinuation due to weight gain occurred in 1% of olanzapine-treated patients, compared to 0% of placebo-treated patients.

Table 7: Weight Gain with Olanzapine Use in Adolescents from 4 Placebo-Controlled Trials Olanzapine-treated patients Placebo-treated patients Mean change in body weight from baseline (median exposure = 3 weeks) 4.6 kg (10.1 lb) 0.3 kg (0.7 lb) Percentage of patients who gained at least 7% of baseline body weight 40.6% (median exposure to 7% = 4 weeks) 9.8% (median exposure to 7% = 8 weeks) Percentage of patients who gained at least 15% of baseline body weight 7.1% (median exposure to 15% = 19 weeks) 2.7% (median exposure to 15% = 8 weeks) In long-term studies (at least 24 weeks), the mean weight gain was 11.2 kg (24.6 lb); (median exposure of 201 days, N=179).

The percentages of adolescents who gained at least 7%, 15%, or 25% of their baseline body weight with long-term exposure were 89%, 55%, and 29%, respectively.

Among adolescent patients, mean weight gain by baseline BMI category was 11.5 kg (25.3 lb), 12.1 kg (26.6 lb), and 12.7 kg (27.9 lb), respectively, for normal (N=106), overweight (N=26) and obese (N=17).

Discontinuation due to weight gain occurred in 2.2% of olanzapine-treated patients following at least 24 weeks of exposure.

Table 8 shows data on adolescent weight gain with olanzapine pooled from 6 clinical trials.

The data in each column represent data for those patients who completed treatment periods of the durations specified.

Little clinical trial data is available on weight gain in adolescents with olanzapine beyond 6 months of treatment.

Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome.

Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown.

The risk of developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase.

However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses or may even arise after discontinuation of treatment.

Tardive dyskinesia may remit, partially or completely, if antipsychotic treatment is withdrawn.

Antipsychotic treatment, itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome and thereby may possibly mask the underlying process.

The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown.

Given these considerations, olanzapine should be prescribed in a manner that is most likely to minimize the occurrence of tardive dyskinesia.

Chronic antipsychotic treatment should generally be reserved for patients (1) who suffer from a chronic illness that is known to respond to antipsychotic drugs, and (2) for whom alternative, equally effective, but potentially less harmful treatments are not available or appropriate.

In patients who do require chronic treatment, the smallest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought.

The need for continued treatment should be reassessed periodically.

If signs and symptoms of tardive dyskinesia appear in a patient on olanzapine, drug discontinuation should be considered.

However, some patients may require treatment with olanzapine despite the presence of the syndrome.

For specific information about the warnings of lithium or valproate, refer to the Warnings section of the package inserts for these other products.

5.7 Orthostatic Hypotension Olanzapine may induce orthostatic hypotension associated with dizziness, tachycardia, bradycardia and, in some patients, syncope, especially during the initial dose-titration period, probably reflecting its α 1 -adrenergic antagonistic properties [see Patient Counseling Information (17) ] .

From an analysis of the vital sign data in an integrated database of 41 completed clinical studies in adult patients treated with oral olanzapine, orthostatic hypotension was recorded in ≥20% (1277/6030) of patients.

For oral olanzapine therapy, the risk of orthostatic hypotension and syncope may be minimized by initiating therapy with 5 mg QD [see Dosage and Administration (2) ] .

A more gradual titration to the target dose should be considered if hypotension occurs.

Syncope was reported in 0.6% (15/2500) of olanzapine-treated patients in phase 2-3 oral olanzapine studies.

The risk for this sequence of hypotension, bradycardia, and sinus pause may be greater in nonpsychiatric patients compared to psychiatric patients who are possibly more adapted to certain effects of psychotropic drugs.

Olanzapine should be used with particular caution in patients with known cardiovascular disease (history of myocardial infarction or ischemia, heart failure, or conduction abnormalities), cerebrovascular disease, and conditions which would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medications) where the occurrence of syncope, or hypotension and/or bradycardia might put the patient at increased medical risk.

Caution is necessary in patients who receive treatment with other drugs having effects that can induce hypotension, bradycardia, respiratory or central nervous system depression [see Drug Interactions (7) ] .

5.8 Falls Olanzapine may cause somnolence, postural hypotension, motor and sensory instability, which may lead to falls and, consequently, fractures or other injuries.

For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy.

5.9 Leukopenia, Neutropenia, and Agranulocytosis Class Effect — In clinical trial and/or postmarketing experience, events of leukopenia/neutropenia have been reported temporally related to antipsychotic agents, including olanzapine.

Agranulocytosis has also been reported.

Possible risk factors for leukopenia/neutropenia include pre-existing low white blood cell count (WBC) and history of drug induced leukopenia/neutropenia.

Patients with a history of a clinically significant low WBC or drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and discontinuation of olanzapine should be considered at the first sign of a clinically significant decline in WBC in the absence of other causative factors.

Patients with clinically significant neutropenia should be carefully monitored for fever or other symptoms or signs of infection and treated promptly if such symptoms or signs occur.

Patients with severe neutropenia (absolute neutrophil count <1000/mm 3 ) should discontinue olanzapine and have their WBC followed until recovery.

5.10 Dysphagia Esophageal dysmotility and aspiration have been associated with antipsychotic drug use.

Aspiration pneumonia is a common cause of morbidity and mortality in patients with advanced Alzheimer’s disease.

Olanzapine is not approved for the treatment of patients with Alzheimer’s disease.

5.11 Seizures During premarketing testing, seizures occurred in 0.9% (22/2500) of olanzapine-treated patients.

There were confounding factors that may have contributed to the occurrence of seizures in many of these cases.

Olanzapine should be used cautiously in patients with a history of seizures or with conditions that potentially lower the seizure threshold, e.g., Alzheimer’s dementia.

Olanzapine is not approved for the treatment of patients with Alzheimer’s disease.

Conditions that lower the seizure threshold may be more prevalent in a population of 65 years or older.

5.12 Potential for Cognitive and Motor Impairment Somnolence was a commonly reported adverse reaction associated with olanzapine treatment, occurring at an incidence of 26% in olanzapine patients compared to 15% in placebo patients.

This adverse reaction was also dose related.

Somnolence led to discontinuation in 0.4% (9/2500) of patients in the premarketing database.

Since olanzapine has the potential to impair judgment, thinking, or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine therapy does not affect them adversely [see Patient Counseling Information (17) ] .

5.13 Body Temperature Regulation Disruption of the body’s ability to reduce core body temperature has been attributed to antipsychotic agents.

Appropriate care is advised when prescribing olanzapine for patients who will be experiencing conditions which may contribute to an elevation in core body temperature, e.g., exercising strenuously, exposure to extreme heat, receiving concomitant medication with anticholinergic activity, or being subject to dehydration [see Patient Counseling Information (17) ].

5.14 Anticholinergic (antimuscarinic) Effects Olanzapine exhibits in vitro muscarinic receptor affinity [see Clinical Pharmacology 12.2 ] .

In premarketing clinical trials, olanzapine was associated with constipation, dry mouth, and tachycardia, all adverse reactions possibly related to cholinergic antagonism.

Such adverse reactions were not often the basis for discontinuations, but olanzapine should be used with caution in patients with a current diagnosis or prior history of urinary retention, clinically significant prostatic hypertrophy, constipation, or a history of paralytic ileus or related conditions.

In post marketing experience, the risk for severe adverse reactions (including fatalities) was increased with concomitant use of anticholinergic medications [see Drug Interactions (7.1 )].

5.15 Hyperprolactinemia As with other drugs that antagonize dopamine D 2 receptors, olanzapine elevates prolactin levels, and the elevation persists during chronic administration.

Hyperprolactinemia may suppress hypothalamic GnRH, resulting in reduced pituitary gonadotropin secretion.

This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients.

Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds.

Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male subjects.

Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin dependent in vitro , a factor of potential importance if the prescription of these drugs is contemplated in a patient with previously detected breast cancer.

As is common with compounds which increase prolactin release, an increase in mammary gland neoplasia was observed in the olanzapine carcinogenicity studies conducted in mice and rats [see Nonclinical Toxicology (13.1) ] .

Neither clinical studies nor epidemiologic studies conducted to date have shown an association between chronic administration of this class of drugs and tumorigenesis in humans; the available evidence is considered too limited to be conclusive at this time.

In placebo-controlled olanzapine clinical studies (up to 12 weeks), changes from normal to high in prolactin concentrations were observed in 30% of adults treated with olanzapine as compared to 10.5% of adults treated with placebo.

In a pooled analysis from clinical studies including 8136 adults treated with olanzapine, potentially associated clinical manifestations included menstrual-related events 1 (2% [49/3240] of females), sexual function-related events 2 (2% [150/8136] of females and males), and breast-related events 3 (0.7% [23/3240] of females, 0.2% [9/4896] of males).

In placebo-controlled olanzapine monotherapy studies in adolescent patients (up to 6 weeks) with schizophrenia or bipolar I disorder (manic or mixed episodes), changes from normal to high in prolactin concentrations were observed in 47% of olanzapine­-treated patients compared to 7% of placebo-treated patients.

In a pooled analysis from clinical trials including 454 adolescents treated with olanzapine, potentially associated clinical manifestations included menstrual-related events 1 (1% [2/168] of females), sexual function-related events 2 (0.7% [3/454] of females and males), and breast-related events 3 (2% [3/168] of females, 2% [7/286] of males) [see Use in Specific Populations (8.4) ] .

1 Based on a search of the following terms: amenorrhea, hypomenorrhea, menstruation delayed, and oligomenorrhea.

2 Based on a search of the following terms: anorgasmia, delayed ejaculation, erectile dysfunction, decreased libido, loss of libido, abnormal orgasm, and sexual dysfunction.

3 Based on a search of the following terms: breast discharge, enlargement or swelling, galactorrhea, gynecomastia, and lactation disorder.

Dose group differences with respect to prolactin elevation have been observed.

In a single 8-week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200) and 40 (N=200) mg/day of oral olanzapine in adult patients with schizophrenia or schizoaffective disorder, incidence of prolactin elevation >24.2 ng/mL (female) or >18.77 ng/mL (male) at any time during the trial (10 mg/day: 31.2%; 20 mg/day: 42.7%; 40 mg/day: 61.1%) indicated significant differences between 10 vs 40 mg/day and 20 vs 40 mg/day.

5.16 Use in Combination with Fluoxetine, Lithium, or Valproate When using olanzapine and fluoxetine in combination, the prescriber should also refer to the Warnings and Precautions section of the package insert for Symbyax.

When using olanzapine in combination with lithium or valproate, the prescriber should refer to the Warnings and Precautions sections of the package inserts for lithium or valproate [see Drug Interactions (7) ].

5.17 Laboratory Tests Fasting blood glucose testing and lipid profile at the beginning of, and periodically during, treatment is recommended [see Warnings and Precautions (5.5) and Patient Counseling Information (17 )].

INFORMATION FOR PATIENTS

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide) for the oral formulations.

Patients should be advised of the following issues and asked to alert their prescriber if these occur while taking olanzapine as monotherapy or in combination with fluoxetine.

If you do not think you are getting better or have any concerns about your condition while taking olanzapine, call your doctor.

When using olanzapine and fluoxetine in combination, also refer to the Patient Counseling Information section of the package insert for Symbyax.

Elderly Patients with Dementia-Related Psychosis: Increased Mortality and Cerebrovascular Adverse Events (CVAE), Including Stroke Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with olanzapine had a significantly higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) compared with placebo.

Olanzapine is not approved for elderly patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions (5.1)] .

Neuroleptic Malignant Syndrome (NMS) Patients and caregivers should be counseled that a potentially fatal symptom complex sometimes referred to as NMS has been reported in association with administration of antipsychotic drugs, including olanzapine.

Signs and symptoms of NMS include hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia) [see Warnings and Precautions (5.3)] .

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Patients should be advised to report to their health care provider at the earliest onset of any signs and symptoms that may be associated with Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) [see Warnings and Precautions (5.4)] .

Hyperglycemia and Diabetes Mellitus Patients should be advised of the potential risk of hyperglycemia-related adverse reactions.

Patients should be monitored regularly for worsening of glucose control.

Patients who have diabetes should follow their doctor’s instructions about how often to check their blood sugar while taking olanzapine [see Warnings and Precautions (5.5)] .

Dyslipidemia Patients should be counseled that dyslipidemia has occurred during treatment with olanzapine.

Patients should have their lipid profile monitored regularly [see Warnings and Precautions (5.5)] .

Weight Gain Patients should be counseled that weight gain has occurred during treatment with olanzapine.

Patients should have their weight monitored regularly [see Warnings and Precautions (5.5)] .

Orthostatic Hypotension Patients should be advised of the risk of orthostatic hypotension, especially during the period of initial dose titration and in association with the use of concomitant drugs that may potentiate the orthostatic effect of olanzapine, e.g., diazepam or alcohol [see Warnings and Precautions (5.7) and Drug Interactions (7)] .

Patients should be advised to change positions carefully to help prevent orthostatic hypotension, and to lie down if they feel dizzy or faint, until they feel better.

Patients should be advised to call their doctor if they experience any of the following signs and symptoms associated with orthostatic hypotension: dizziness, fast or slow heartbeat, or fainting.

Potential for Cognitive and Motor Impairment Because olanzapine has the potential to impair judgment, thinking, or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine therapy does not affect them adversely [see Warnings and Precautions (5.12)] .

Body Temperature Regulation Patients should be advised regarding appropriate care in avoiding overheating and dehydration.

Patients should be advised to call their doctor right away if they become severely ill and have some or all of these symptoms of dehydration: sweating too much or not at all, dry mouth, feeling very hot, feeling thirsty, not able to produce urine [see Warnings and Precautions (5.13)] .

Concomitant Medication Patients should be advised to inform their healthcare providers if they are taking, or plan to take, Symbyax.

Patients should also be advised to inform their healthcare providers if they are taking, plan to take, or have stopped taking any prescription or over-the-counter drugs, including herbal supplements, since there is a potential for interactions [see Drug Interactions (7)] .

Alcohol Patients should be advised to avoid alcohol while taking olanzapine [see Drug Interactions (7)] .

Phenylketonurics Olanzapine orally disintegrating tablets contain phenylalanine (1.12, 2.24, 3.36, or 4.48 mg per 5, 10, 15, or 20 mg tablet, respectively) [see Description (11)].

Use in Specific Populations Pregnancy — Advise women to notify their healthcare provider if they become pregnant or intend to become pregnant during treatment with olanzapine.

Advise patients that olanzapine may cause extrapyramidal and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder) in a neonate.

Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to olanzapine during pregnancy [see Use in Specific Populations (8.1)] .

Lactation — Advise breastfeeding women using olanzapine to monitor infants for excess sedation, irritability, poor feeding and extrapyramidal symptoms (tremors and abnormal muscle movements) and to seek medical care if they notice these signs.

[see Use in Specific Populations (8.3)] .

Infertility — Advise females of reproductive potential that olanzapine may impair fertility due to an increase in serum prolactin levels.

The effects on fertility are reversible [see Use in Specific Populations (8.3)].

Pediatric Use — Olanzapine is indicated for treatment of schizophrenia and manic or mixed episodes associated with bipolar I disorder in adolescents 13 to 17 years of age.

Compared to patients from adult clinical trials, adolescents were likely to gain more weight, experience increased sedation, and have greater increases in total cholesterol, triglycerides, LDL cholesterol, prolactin, and hepatic aminotransferase levels.

Patients should be counseled about the potential long-term risks associated with olanzapine and advised that these risks may lead them to consider other drugs first [see Indications and Usage (1.1, 1.2)] .

Safety and effectiveness of olanzapine in patients under 13 years of age have not been established.

Safety and efficacy of olanzapine and fluoxetine in combination in patients 10 to 17 years of age have been established for the acute treatment of depressive episodes associated with bipolar I disorder.

Safety and effectiveness of olanzapine and fluoxetine in combination in patients <10 years of age have not been established [see Warnings and Precautions (5.5) and Use in Specific Populations (8.4)] .

Need for Comprehensive Treatment Program in Pediatric Patients Olanzapine is indicated as an integral part of a total treatment program for pediatric patients with schizophrenia and bipolar disorder that may include other measures (psychological, educational, social) for patients with the disorder.

Effectiveness and safety of olanzapine have not been established in pediatric patients less than 13 years of age.

Atypical antipsychotics are not intended for use in the pediatric patient who exhibits symptoms secondary to environmental factors and/or other primary psychiatric disorders.

Appropriate educational placement is essential and psychosocial intervention is often helpful.

The decision to prescribe atypical antipsychotic medication will depend upon the healthcare provider’s assessment of the chronicity and severity of the patient’s symptoms [see Indications and Usage (1.3)] .

( 2.1 ) Olanzapine may be given without regard to meals.

( 2.1 ) Olanzapine and Fluoxetine in Combination: Dosage adjustments, if indicated, should be made with the individual components according to efficacy and tolerability.

( 2.5, 2.6 ) Olanzapine monotherapy is not indicated for the treatment of depressive episodes associated with bipolar I disorder or treatment resistant depression.

( 2.5, 2.6 ) Safety of co-administration of doses above 18 mg olanzapine with 75 mg fluoxetine has not been evaluated in adults.

( 2.5, 2.6 ) Safety of co-administration of doses above 12 mg olanzapine with 50 mg fluoxetine has not been evaluated in children and adolescents ages 10 to 17.

(2.5) 2.1 Schizophrenia Adults Dose Selection — Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 5 to 10 mg initially, with a target dose of 10 mg/day within several days.

Further dosage adjustments, if indicated, should generally occur at intervals of not less than 1 week, since steady state for olanzapine would not be achieved for approximately 1 week in the typical patient.

When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended.

Efficacy in schizophrenia was demonstrated in a dose range of 10 to 15 mg/day in clinical trials.

However, doses above 10 mg/day were not demonstrated to be more efficacious than the 10 mg/day dose.

An increase to a dose greater than the target dose of 10 mg/day (i.e., to a dose of 15 mg/day or greater) is recommended only after clinical assessment.

Olanzapine is not indicated for use in doses above 20 mg/day.

Dosing in Special Populations — The recommended starting dose is 5 mg in patients who are debilitated, who have a predisposition to hypotensive reactions, who otherwise exhibit a combination of factors that may result in slower metabolism of olanzapine (e.g., nonsmoking female patients ≥65 years of age), or who may be more pharmacodynamically sensitive to olanzapine [see Warnings and Precautions (5.14), Drug Interactions (7) , and Clinical Pharmacology (12.3) ] .

When indicated, dose escalation should be performed with caution in these patients.

Maintenance Treatment — The effectiveness of oral olanzapine, 10 mg/day to 20 mg/day, in maintaining treatment response in schizophrenic patients who had been stable on olanzapine orally disintegrating tablets for approximately 8 weeks and were then followed for relapse has been demonstrated in a placebo-controlled trial [see Clinical Studies (14.1) ] .

The healthcare provider who elects to use olanzapine orally disintegrating tablets for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

Adolescents Dose Selection — Oral olanzapine should be administered on a once-a-day schedule without regard to meals with a recommended starting dose of 2.5 or 5 mg, with a target dose of 10 mg/day.

Efficacy in adolescents with schizophrenia was demonstrated based on a flexible dose range of 2.5 to 20 mg/day in clinical trials, with a mean modal dose of 12.5 mg/day (mean dose of 11.1 mg/day).

When dosage adjustments are necessary, dose increments/decrements of 2.5 or 5 mg are recommended.

The safety and effectiveness of doses above 20 mg/day have not been evaluated in clinical trials [ see Clinical Studies (14.1)] .

Maintenance Treatment — The efficacy of olanzapine orally disintegrating tablets for the maintenance treatment of schizophrenia in the adolescent population has not been systematically evaluated; however, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients.

Thus, it is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission.

Patients should be periodically reassessed to determine the need for maintenance treatment.

2.2 Bipolar I Disorder (Manic or Mixed Episodes) Adults Dose Selection for Monotherapy — Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 10 or 15 mg.

Dosage adjustments, if indicated, should generally occur at intervals of not less than 24 hours, reflecting the procedures in the placebo-controlled trials.

When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended.

Short-term (3-4 weeks) antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials.

The safety of doses above 20 mg/day has not been evaluated in clinical trials [see Clinical Studies (14.2)].

Maintenance Monotherapy — The benefit of maintaining bipolar I patients on monotherapy with olanzapine orally disintegrating tablets at a dose of 5 to 20 mg/day, after achieving a responder status for an average duration of 2 weeks, was demonstrated in a controlled trial [ see Clinical Studies (14.2) ] .

The healthcare provider who elects to use olanzapine orally disintegrating tablets for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

Dose Selection for Adjunctive Treatment — When administered as adjunctive treatment to lithium or valproate, oral olanzapine dosing should generally begin with 10 mg once-a-day without regard to meals.

Antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials [see Clinical Studies (14.2)] .

The safety of doses above 20 mg/day has not been evaluated in clinical trials.

Adolescents Dose Selection — Oral olanzapine should be administered on a once-a-day schedule without regard to meals with a recommended starting dose of 2.5 or 5 mg, with a target dose of 10 mg/day.

Efficacy in adolescents with bipolar I disorder (manic or mixed episodes) was demonstrated based on a flexible dose range of 2.5 to 20 mg/day in clinical trials, with a mean modal dose of 10.7 mg/day (mean dose of 8.9 mg/day).

When dosage adjustments are necessary, dose increments/decrements of 2.5 or 5 mg are recommended.

The safety and effectiveness of doses above 20 mg/day have not been evaluated in clinical trials [see Clinical Studies (14.2)] .

Maintenance Treatment — The efficacy of olanzapine orally disintegrating tablets for the maintenance treatment of bipolar I disorder in the adolescent population has not been evaluated; however, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients.

Thus, it is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission.

Patients should be periodically reassessed to determine the need for maintenance treatment.

2.3 Administration of Olanzapine Orally Disintegrating Tablets Peel back foil on blister.

Do not push tablet through foil.

Immediately upon opening the blister, using dry hands, remove tablet and place entire olanzapine orally disintegrating tablet in the mouth.

Tablet disintegration occurs rapidly in saliva so it can be easily swallowed with or without liquid.

2.5 Olanzapine and Fluoxetine in Combination: Depressive Episodes Associated with Bipolar I Disorder When using olanzapine and fluoxetine in combination, also refer to the Clinical Studies section of the package insert for Symbyax.

Adults Oral olanzapine should be administered in combination with fluoxetine once daily in the evening, without regard to meals, generally beginning with 5 mg of oral olanzapine and 20 mg of fluoxetine.

Dosage adjustments, if indicated, can be made according to efficacy and tolerability within dose ranges of oral olanzapine 5 to 12.5 mg and fluoxetine 20 to 50 mg.

Antidepressant efficacy was demonstrated with olanzapine and fluoxetine in combination in adult patients with a dose range of olanzapine 6 to 12 mg and fluoxetine 25 to 50 mg.

Safety of co-administration of doses above 18 mg olanzapine with 75 mg fluoxetine has not been evaluated in clinical studies.

Children and Adolescents (10 to 17 years of age) Oral olanzapine should be administered in combination with fluoxetine once daily in the evening, without regard to meals, generally beginning with 2.5 mg of oral olanzapine and 20 mg of fluoxetine.

Dosage adjustments, if indicated, can be made according to efficacy and tolerability.

Safety of co-administration of doses above 12 mg olanzapine with 50 mg fluoxetine has not been evaluated in pediatric clinical studies.

Safety and efficacy of olanzapine and fluoxetine in combination was determined in clinical trials supporting approval of Symbyax (fixed dose combination of olanzapine and fluoxetine).

Symbyax is dosed between 3 mg/25 mg (olanzapine/fluoxetine) per day and 12 mg/50 mg (olanzapine/fluoxetine) per day.

The following table demonstrates the appropriate individual component doses of olanzapine and fluoxetine versus Symbyax.

Dosage adjustments, if indicated, should be made with the individual components according to efficacy and tolerability.

Table 1: Approximate Dose Correspondence Between Symbyax a and the Combination of Olanzapine and Fluoxetine For Symbyax (mg/day) Use in Combination Olanzapine (mg/day) Fluoxetine (mg/day) 3 mg olanzapine/25 mg fluoxetine 2.5 20 6 mg olanzapine/25 mg fluoxetine 5 20 12 mg olanzapine/25 mg fluoxetine 10+2.5 20 6 mg olanzapine/50 mg fluoxetine 5 40+10 12 mg olanzapine/50 mg fluoxetine 10+2.5 40+10 a Symbyax (olanzapine/fluoxetine HCl) is a fixed-dose combination of olanzapine and fluoxetine.

While there is no body of evidence to answer the question of how long a patient treated with olanzapine and fluoxetine in combination should remain on it, it is generally accepted that bipolar I disorder, including the depressive episodes associated with bipolar I disorder, is a chronic illness requiring chronic treatment.

The healthcare provider should periodically reexamine the need for continued pharmacotherapy.

Olanzapine orally disintegrating tablets monotherapy is not indicated for the treatment of depressive episodes associated with bipolar I disorder.

2.6 Olanzapine and Fluoxetine in Combination: Treatment Resistant Depression When using olanzapine and fluoxetine in combination, also refer to the Clinical Studies section of the package insert for Symbyax.

Oral olanzapine should be administered in combination with fluoxetine once daily in the evening, without regard to meals, generally beginning with 5 mg of oral olanzapine and 20 mg of fluoxetine.

Dosage adjustments, if indicated, can be made according to efficacy and tolerability within dose ranges of oral olanzapine 5 to 20 mg and fluoxetine 20 to 50 mg.

Antidepressant efficacy was demonstrated with olanzapine and fluoxetine in combination in adult patients with a dose range of olanzapine 6 to 18 mg and fluoxetine 25 to 50 mg.

Safety and efficacy of olanzapine in combination with fluoxetine was determined in clinical trials supporting approval of Symbyax (fixed dose combination of olanzapine and fluoxetine).

Symbyax is dosed between 3 mg/25 mg (olanzapine/fluoxetine) per day and 12 mg/50 mg (olanzapine/fluoxetine) per day.

Table 1 above demonstrates the appropriate individual component doses of olanzapine and fluoxetine versus Symbyax.

Dosage adjustments, if indicated, should be made with the individual components according to efficacy and tolerability.

While there is no body of evidence to answer the question of how long a patient treated with olanzapine and fluoxetine in combination should remain on it, it is generally accepted that treatment resistant depression (major depressive disorder in adult patients who do not respond to 2 separate trials of different antidepressants of adequate dose and duration in the current episode) is a chronic illness requiring chronic treatment.

The healthcare provider should periodically reexamine the need for continued pharmacotherapy.

Safety of co-administration of doses above 18 mg olanzapine with 75 mg fluoxetine has not been evaluated in clinical studies.

Olanzapine orally disintegrating tablets monotherapy is not indicated for treatment of treatment resistant depression (major depressive disorder in patients who do not respond to 2 antidepressants of adequate dose and duration in the current episode).

2.7 Olanzapine and Fluoxetine in Combination: Dosing in Special Populations The starting dose of oral olanzapine 2.5 to 5 mg with fluoxetine 20 mg should be used for patients with a predisposition to hypotensive reactions, patients with hepatic impairment, or patients who exhibit a combination of factors that may slow the metabolism of olanzapine or fluoxetine in combination (female gender, geriatric age, nonsmoking status), or those patients who may be pharmacodynamically sensitive to olanzapine.

Dosing modification may be necessary in patients who exhibit a combination of factors that may slow metabolism.

When indicated, dose escalation should be performed with caution in these patients.

Olanzapine and fluoxetine in combination have not been systematically studied in patients over 65 years of age or in patients under 10 years of age [see Warnings and Precautions (5.14) , Drug Interactions (7) , and Clinical Pharmacology (12.3) ] .

OVERDOSAGE

10 Human Experience In premarketing clinical studies, there were reports of REMERON overdose alone or in combination with other pharmacological agents.

Signs and symptoms reported in association with overdose included disorientation, drowsiness, impaired memory, and tachycardia.

Based on postmarketing reports, serious outcomes (including fatalities) may occur at dosages higher than the recommended doses, especially with mixed overdoses.

In these cases, QT prolongation and Torsades de Pointes have also been reported [see Warnings and Precautions (5.5) , Adverse Reactions (6.2) , and Drug Interactions (7) ].

Overdose Management No specific antidotes for mirtazapine are known.

Contact Poison Control (1-800-222-1222) for the latest recommendations.

Chemical Structure

CLINICAL STUDIES

14 The efficacy of REMERON as a treatment for major depressive disorder was established in 4 placebo-controlled, 6-week trials in adult outpatients meeting DSM-III criteria for major depressive disorder.

Patients were titrated with REMERON from a dose range of 5 mg to 35 mg/day.

The mean mirtazapine dose for patients who completed these 4 studies ranged from 21 to 32 mg/day.

Overall, these studies demonstrated REMERON to be superior to placebo on at least 3 of the following 4 measures: 21-Item Hamilton Depression Rating Scale (HDRS) total score; HDRS Depressed Mood Item; CGI Severity score; and Montgomery and Asberg Depression Rating Scale (MADRS).

Superiority of REMERON over placebo was also found for certain factors of the HDRS, including anxiety/somatization factor and sleep disturbance factor.

Examination of age and gender subsets of the population did not reveal any differential responsiveness on the basis of these subgroupings.

In a longer-term study, patients meeting (DSM-IV) criteria for major depressive disorder who had responded during an initial 8 to 12 weeks of acute treatment on REMERON were randomized to continuation of REMERON or placebo for up to 40 weeks of observation for relapse.

Response during the open phase was defined as having achieved a HAM-D 17 total score of ≤8 and a CGI-Improvement score of 1 or 2 at 2 consecutive visits beginning with week 6 of the 8 to 12 weeks in the open-label phase of the study.

Relapse during the double-blind phase was determined by the individual investigators.

Patients receiving continued REMERON treatment experienced significantly lower relapse rates over the subsequent 40 weeks compared to those receiving placebo.

This pattern was demonstrated in both male and female patients.

GERIATRIC USE

8.5 Geriatric Use Approximately 190 patients ≥65 years of age participated in clinical studies with REMERON.

REMERON/REMERONSolTab is known to be substantially excreted by the kidney (75%), and the risk of decreased clearance of this drug is greater in patients with impaired renal function.

Pharmacokinetic studies revealed a decreased clearance of mirtazapine in the elderly [see Clinical Pharmacology (12.3) ] .

Sedating drugs, including REMERON/REMERONSolTab, may cause confusion and over-sedation in the elderly.

Elderly patients may be at greater risk of developing hyponatremia.

Caution is indicated when administering REMERON/REMERONSolTab to elderly patients [see Warnings and Precautions (5.11) , (5.14) and Clinical Pharmacology (12.3) ] .

In general, dose selection for an elderly patient should be conservative, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

MECHANISM OF ACTION

12.1 Mechanism of Action The mechanism of action of mirtazapine for the treatment of major depressive disorder, is unclear.

However, its efficacy could be mediated through its activity as an antagonist at central presynaptic α 2 -adrenergic inhibitory autoreceptors and heteroreceptors and enhancing central noradrenergic and serotonergic activity.

INDICATIONS AND USAGE

1 REMERON/REMERONSolTab are indicated for the treatment of major depressive disorder (MDD) in adults [see Clinical Studies (14) ] .

REMERON/REMERONSolTab is indicated for the treatment of major depressive disorder (MDD) in adults.

PEDIATRIC USE

8.4 Pediatric Use The safety and effectiveness of REMERON/REMERONSolTab have not been established in pediatric patients with MDD.

Two placebo-controlled trials in 258 pediatric patients with MDD have been conducted with REMERON, and the data were insufficient to establish the safety and effectiveness of REMERON/REMERONSolTab in pediatric patients with MDD.

Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning and Warnings and Precautions (5.1) ] .

In an 8-week-long clinical trial in pediatric patients receiving doses between 15 to 45 mg per day, 49% of REMERON-treated patients had a weight gain of at least 7%, compared to 5.7% of placebo-treated patients.

The mean increase in weight was 4 kg (2 kg SD) for REMERON-treated patients versus 1 kg (2 kg SD) for placebo-treated patients [see Warnings and Precautions (5.6) ] .

PREGNANCY

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy.

Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/.

Risk Summary Prolonged experience with mirtazapine in pregnant women, based on published observational studies and postmarketing reports, has not reliably identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.

There are risks associated with untreated depression in pregnancy (see Clinical Considerations ).

In animal reproduction studies, oral administration of mirtazapine to pregnant rats and rabbits during the period of organogenesis revealed no evidence of teratogenic effects up to 20 and 17 times the maximum recommended human dose (MRHD) of 45 mg, respectively, based on mg/m 2 body surface area.

However, in rats, there was an increase in postimplantation loss at 20 times the MRHD based on mg/m 2 body surface area.

Oral administration of mirtazapine to pregnant rats during pregnancy and lactation resulted in an increase in pup deaths and a decrease in pup birth weights at doses 20 times the MRHD based on mg/m 2 body surface area (see Data ).

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.

All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

In the U.S.

general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants.

This finding is from a prospective, longitudinal study that followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy.

Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum.

Data Animal Data Mirtazapine was administered orally to pregnant rats and rabbits during the period of organogenesis at doses of 2.5, 15, and 100 mg/kg/day and 2.5, 10, and 40 mg/kg/day, respectively, which are up to 20 and 17 times the maximum recommended human dose (MRHD) of 45 mg based on mg/m 2 body surface area, respectively.

No evidence of teratogenic effects was observed.

However, in rats, there was an increase in postimplantation loss in dams treated with mirtazapine at 100 mg/kg/day which is 20 times the MRHD based on mg/m 2 body surface area.

Oral administration of mirtazapine at doses of 2.5, 15, and 100 mg/kg/day to pregnant rats during pregnancy and lactation resulted in an increase in pup deaths during the first 3 days of lactation and a decrease in pup birth weights at 20 times the MRHD based on mg/m 2 body surface area.

The cause of these deaths is not known.

The no effect dose level is 3 times the MRHD based on mg/m 2 body surface area.

BOXED WARNING

REMERON/REMERONSolTab is not approved for use in pediatric patients.

( 5.1 , 8.4 )

WARNING AND CAUTIONS

5 WARNINGS AND PRECAUTIONS Agranulocytosis : If sore throat, fever, stomatitis or signs of infection occur, along with a low white blood cell count, treatment with REMERON/REMERONSolTab should be discontinued and the patient should be closely monitored.

( 5.2 ) Serotonin Syndrome : Increased risk when co-administered with other serotonergic drugs (e.g., SSRI, SNRI, triptans), but also when taken alone.

If it occurs, discontinue REMERON/REMERONSolTab and initiate supportive treatment.

( 2.4 , 4 , 5.3 , 7 ) Angle-Closure Glaucoma : Angle closure glaucoma has occurred in patients with untreated anatomically narrow angles treated with antidepressants.

( 5.4 ) QT Prolongation : Use REMERON/REMERONSolTab with caution in patients with risk factors for QT prolongation.

( 5.5 , 7 ) Increased Appetite/Weight Gain : REMERON/REMERONSolTab has been associated with increased appetite and weight gain.

( 5.6 ) Somnolence : May impair judgment, thinking and/or motor skills.

Use with caution when engaging in activities requiring alertness, such as driving or operating machinery.

( 5.7 , 7 ) Activation of Mania/Hypomania : Screen patients for bipolar disorder prior to initiating treatment.

( 2.3 , 5.8 ) Seizures : Use with caution in patients with a seizure disorder.

( 5.9 ) Elevated Cholesterol/Triglycerides : Has been reported with REMERON use.

( 5.10 ) Hyponatremia : May occur as a result of treatment with serotonergic antidepressants, including REMERON/REMERONSolTab.

( 5.11 ) Transaminase Elevations : Clinically significant elevations have occurred.

Use with caution in patients with impaired hepatic function.

( 5.12 ) 5.1 Suicidal Thoughts and Behaviors in Adolescents and Young Adults In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients.

There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied.

There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD.

The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 1.

Table 1: Risk Differences of the Number of Patients with Suicidal Thoughts and Behavior in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients Age Range Drug-Placebo Difference in Number of Patients with Suicidal Thoughts or Behaviors per 1000 Patients Treated Increases Compared to Placebo <18 years old 14 additional patients 18–24 years old 5 additional patients Decreases Compared to Placebo 25–64 years old 1 fewer patient ≥65 years old 6 fewer patients It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months.

However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors.

Monitor all antidepressant-treated patients for any indication of clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy, and at times of dosage changes.

Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider.

Consider changing the therapeutic regimen, including possibly discontinuing REMERON/REMERONSolTab, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

5.2 Agranulocytosis In premarketing clinical trials, 2 (1 with Sjögren’s Syndrome) out of 2796 patients treated with REMERON developed agranulocytosis [absolute neutrophil count (ANC) <500/mm 3 with associated signs and symptoms, e.g., fever, infection, etc.] and a third patient developed severe neutropenia (ANC <500/mm 3 without any associated symptoms).

For these 3 patients, onset of severe neutropenia was detected on days 61, 9, and 14 of treatment, respectively.

All 3 patients recovered after REMERON was stopped.

If a patient develops a sore throat, fever, stomatitis, or other signs of infection, along with a low white blood cell (WBC) count, treatment with REMERON/REMERONSolTab should be discontinued and the patient should be closely monitored.

5.3 Serotonin Syndrome Serotonergic antidepressants, including REMERON/REMERONSolTab, can precipitate serotonin syndrome, a potentially life-threatening condition.

The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St.

John’s Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Contraindications (4) , Drug Interactions (7) ] .

Serotonin syndrome can also occur when these drugs are used alone.

Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).

The concomitant use of REMERON/REMERONSolTab with MAOIs is contraindicated.

In addition, do not initiate REMERON/REMERONSolTab in a patient being treated with MAOIs such as linezolid or intravenous methylene blue.

No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection).

If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking REMERON/REMERONSolTab, discontinue REMERON/REMERONSolTab before initiating treatment with the MAOI [see Contraindications (4) , Drug Interactions (7) ] .

Monitor all patients taking REMERON/REMERONSolTab for the emergence of serotonin syndrome.

Discontinue treatment with REMERON/REMERONSolTab and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment.

If concomitant use of REMERON/REMERONSolTab with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

5.4 Angle-Closure Glaucoma The pupillary dilation that occurs following use of many antidepressant drugs, including REMERON/REMERONSolTab, may trigger an angle-closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy.

5.5 QT Prolongation and Torsades de Pointes The effect of REMERON (mirtazapine) on QTc interval was assessed in a clinical randomized trial with placebo and positive (moxifloxacin) controls involving 54 healthy volunteers using exposure response analysis.

This trial showed a positive relationship between mirtazapine concentrations and prolongation of the QTc interval.

However, the degree of QT prolongation observed with both 45 mg and 75 mg (1.67 times the maximum recommended daily dose) doses of mirtazapine was not at a level generally considered to be clinically meaningful.

During postmarketing use of mirtazapine, cases of QT prolongation, Torsades de Pointes, ventricular tachycardia, and sudden death, have been reported [see Adverse Reactions (6.1 , 6.2) ] .

The majority of reports occurred in association with overdose or in patients with other risk factors for QT prolongation, including concomitant use of QTc-prolonging medicines [see Drug Interactions (7) and Overdosage (10) ] .

Exercise caution when REMERON/REMERONSolTab is prescribed in patients with known cardiovascular disease or family history of QT prolongation, and in concomitant use with other drugs thought to prolong the QTc interval.

5.6 Increased Appetite and Weight Gain In U.S.

controlled clinical studies, appetite increase was reported in 17% of patients treated with REMERON, compared to 2% for placebo.

In these same trials, weight gain of ≥7% of body weight was reported in 7.5% of patients treated with mirtazapine, compared to 0% for placebo.

In a pool of premarketing U.S.

clinical studies, including many patients for long-term, open-label treatment, 8% of patients receiving REMERON discontinued for weight gain.

In an 8-week-long pediatric clinical trial of doses between 15 to 45 mg/day, 49% of REMERON-treated pediatric patients had a weight gain of at least 7%, compared to 5.7% of placebo-treated patients.

The safety and effectiveness of REMERON/REMERONSolTab in pediatric patients with MDD have not been established [see Use in Specific Populations (8.4) ] .

5.7 Somnolence In U.S.

controlled studies, somnolence was reported in 54% of patients treated with REMERON, compared to 18% for placebo.

In these studies, somnolence resulted in discontinuation for 10.4% of REMERON-treated patients, compared to 2.2% for placebo.

It is unclear whether tolerance develops to the somnolent effects of REMERON/REMERONSolTab.

Because of the potentially significant effects of REMERON/REMERONSolTab on impairment of performance, caution patients about engaging in activities that require alertness, including operating hazardous machinery and motor vehicles, until they are reasonably certain that REMERON/REMERONSolTab does not affect them adversely.

The concomitant use of benzodiazepines and alcohol with REMERON/REMERONSolTab should be avoided [see Drug Interactions (7) ] .

5.8 Activation of Mania or Hypomania In patients with bipolar disorder, treating a depressive episode with REMERON/REMERONSolTab or another antidepressant may precipitate a mixed/manic episode.

In controlled clinical trials, patients with bipolar disorder were generally excluded; however, symptoms of mania or hypomania were reported in 0.2% of patients treated with REMERON.

Prior to initiating treatment with REMERON/REMERONSolTab, screen patients for any personal or family history of bipolar disorder, mania, or hypomania.

5.9 Seizures REMERON/REMERONSolTab has not been systematically evaluated in patients with seizure disorders.

In premarketing clinical trials, 1 seizure was reported among the 2796 U.S.

and non-U.S.

patients treated with REMERON.

REMERON/REMERONSolTab should be prescribed with caution in patients with a seizure disorder.

5.10 Elevated Cholesterol and Triglycerides In U.S.

controlled studies, nonfasting cholesterol increases to ≥20% above the upper limits of normal were observed in 15% of patients treated with REMERON, compared to 7% for placebo.

In these same studies, nonfasting triglyceride increases to ≥500 mg/dL were observed in 6% of patients treated with REMERON, compared to 3% for placebo.

5.11 Hyponatremia Hyponatremia may occur as a result of treatment with serotonergic antidepressants, including REMERON/REMERONSolTab.

Cases with serum sodium lower than 110 mmol/L have been reported.

Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls.

Signs and symptoms associated with more severe or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death.

In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

In patients with symptomatic hyponatremia, discontinue REMERON/REMERONSolTab and institute appropriate medical intervention.

Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia [see Use in Specific Populations (8.5) ] .

5.12 Transaminase Elevations Clinically significant ALT (SGPT) elevations (≥3 times the upper limit of the normal range) were observed in 2.0% (8/424) of patients treated with REMERON in a pool of short-term, U.S.

controlled trials, compared to 0.3% (1/328) of placebo patients.

While some patients were discontinued for the ALT increases, in other cases, the enzyme levels returned to normal despite continued REMERON treatment.

REMERON/REMERONSolTab should be used with caution in patients with impaired hepatic function [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] .

5.13 Discontinuation Syndrome There have been reports of adverse reactions upon the discontinuation of REMERON/REMERONSolTab (particularly when abrupt), including but not limited to the following: dizziness, abnormal dreams, sensory disturbances (including paresthesia and electric shock sensations), agitation, anxiety, fatigue, confusion, headache, tremor, nausea, vomiting, and sweating, or other symptoms which may be of clinical significance.

A gradual reduction in the dosage, rather than an abrupt cessation, is recommended [see Dosage and Administration (2.6) ].

5.14 Use in Patients with Concomitant Illness REMERON/REMERONSolTab has not been systematically evaluated or used to any appreciable extent in patients with a recent history of myocardial infarction or other significant heart disease.

REMERON was associated with significant orthostatic hypotension in early clinical pharmacology trials with normal volunteers.

Orthostatic hypotension was infrequently observed in clinical trials with depressed patients [see Adverse Reactions (6.1) ] .

REMERON/REMERONSolTab should be used with caution in patients with known cardiovascular or cerebrovascular disease that could be exacerbated by hypotension (history of myocardial infarction, angina, or ischemic stroke) and conditions that would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medication).

5.15 Risks in Patients with Phenylketonuria Phenylalanine can be harmful to patients with phenylketonuria (PKU).

REMERONSolTab contains phenylalanine, a component of aspartame.

REMERONSolTab contains the following amount of phenylalanine: 2.6 mg in 15 mg orally disintegrating tablet, 5.2 mg in 30 mg orally disintegrating tablet, and 7.8 mg in 45 mg orally disintegrating tablet.

Before prescribing REMERONSolTab to a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including REMERONSolTab.

INFORMATION FOR PATIENTS

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide).

Suicidal Thoughts and Behaviors Advise patients and caregivers to look for the emergence of suicidality, especially early during treatment and when the dosage is adjusted up or down, and instruct them to report such symptoms to the healthcare provider [see Boxed Warning and Warnings and Precautions (5.1) ].

Agranulocytosis Advise patients to contact their physician if they experience fever, chills, sore throat, mucous membrane ulceration, flu-like complaints, or other symptoms that might suggest infection [see Warnings and Precautions (5.2) ].

Serotonin Syndrome Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of REMERON/REMERONSolTab with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, St.

John’s Wort, and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid).

Advise patients to contact their healthcare provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome [see Dosage and Administration (2.4) , Contraindications (4) , Warnings and Precautions (5.3) , Drug Interactions (7) ].

QT Prolongation and Torsades de Pointes Inform patients to consult their physician immediately if they feel faint, lose consciousness, or have heart palpitations [see Warnings and Precautions (5.5) , Drug Interactions (7) , Overdosage (10) ].

Advise patients to inform physicians that they are taking REMERON/REMERONSolTab before any new drug is taken.

Somnolence Advise patients that REMERON/REMERONSolTab may impair judgment, thinking, and particularly, motor skills, because of its prominent sedative effect.

Caution patients about performing activities requiring mental alertness, such as operating hazardous machinery or operating a motor vehicle, until they are reasonably certain that REMERON/REMERONSolTab therapy does not adversely affect their ability to engage in such activities.

[see Warnings and Precautions (5.7) ].

Alcohol Advise patients to avoid alcohol while taking REMERON/REMERONSolTab [see Warnings and Precautions (5.7) , Drug Interactions (7) ].

Activation of Mania/Hypomania Advise patients and their caregivers to observe for signs of activation of mania/hypomania and instruct them to report such symptoms to the healthcare provider [see Warnings and Precautions (5.8) ] .

Discontinuation Syndrome Advise patients not to abruptly discontinue REMERON/REMERONSolTab and to discuss any tapering regimen with their healthcare provider.

Adverse reactions can occur when REMERON/REMERONSolTab is discontinued [see Dosage and Administration (2.6) , Warnings and Precautions (5.13) ].

Allergic Reactions Advise patients to notify their healthcare provider if they develop an allergic reaction such as rash, hives, swelling, or difficulty breathing [see Contraindications (4) , Adverse Reactions (6.2) ] .

Pregnancy Advise patients to notify their physician if they become pregnant or intend to become pregnant during REMERON/REMERONSolTab therapy.

Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to REMERON/REMERONSolTab during pregnancy [see Use in Specific Populations (8.1) ] .

Lactation Advise patients to notify their physician if they are breastfeeding an infant [see Use in Specific Populations (8.2) ].

Angle-Closure Glaucoma Patients should be advised that taking REMERON can cause mild pupillary dilation, which in susceptible individuals, can lead to an episode of angle-closure glaucoma.

Pre-existing glaucoma is almost always open-angle glaucoma because angle-closure glaucoma, when diagnosed, can be treated definitively with iridectomy.

Open-angle glaucoma is not a risk factor for angle-closure glaucoma.

Patients may wish to be examined to determine whether they are susceptible to angle-closure, and have a prophylactic procedure (e.g., iridectomy), if they are susceptible [see Warnings and Precautions (5.4) .] Patients with Phenylketonuria Inform patients with phenylketonuria that REMERONSolTab contains phenylalanine [see Warnings and Precautions (5.15) ].

The whole tablet should be placed on the tongue and allowed to disintegrate without chewing or crushing.

Do not attempt to split the tablet.

The tablet will disintegrate in saliva so that it can be swallowed.

2.3 Screen for Bipolar Disorder Prior to Starting REMERON/REMERONSolTab Prior to initiating treatment with REMERON/REMERONSolTab or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.8) ].

2.4 Switching Patients to or from a Monoamine Oxidase Inhibitor Antidepressant At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of REMERON/REMERONSolTab.

In addition, at least 14 days must elapse after stopping REMERON/REMERONSolTab before starting an MAOI antidepressant [see Contraindications (4) and Warnings and Precautions (5.3) ] .

2.5 Dosage Modifications Due to Drug Interactions Strong CYP3A Inducers An increase in dosage of REMERON/REMERONSolTab may be needed with concomitant strong CYP3A inducer (e.g., carbamazepine, phenytoin, rifampin) use.

Conversely, a decrease in dosage of REMERON/REMERONSolTab may be needed if the CYP3A inducer is discontinued [see Drug Interactions (7) ].

Strong CYP3A Inhibitors A decrease in dosage of REMERON/REMERONSolTab may be needed with concomitant use of strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin).

Conversely, an increase in dosage of REMERON/REMERONSolTab may be needed if the CYP3A4 inhibitor is discontinued [see Drug Interactions (7) ].

Cimetidine A decrease in dosage of REMERON/REMERONSolTab may be needed with concomitant use of cimetidine.

Conversely, an increase in dosage of REMERON/REMERONSolTab may be needed if cimetidine is discontinued [see Drug Interactions (7) ].

2.6 Discontinuation of REMERON/REMERONSolTab Treatment Adverse reactions may occur upon discontinuation or dose reduction of REMERON/REMERONSolTab [see Warnings and Precautions (5.13) ] .

Gradually reduce the dosage of REMERON/REMERONSolTab rather than stopping abruptly whenever possible.

Prednisone 5 MG Oral Tablet 21 Count Pack

WARNINGS

: In patients on corticosteroid therapy subjected to unusual stress, increased dosage of rapidly acting corticosteroids before, during and after the stressful situation is indicated.

Corticosteroids may mask some signs of infection, and new infections may appear during their use.

Infections with any pathogen including viral, bacterial, fungal, protozoan or helminthic infections, in any location of the body, may be associated with the use of corticosteroids alone or in combination with other immunosuppressive agents that affect cellular immunity, humoral immunity, or neutrophil function.

1 These infections may be mild, but can be severe and at times fatal.

With increasing doses of corticosteroids, the rate of occurrence of infectious complications increases.

2 There may be decreased resistance and inability to localize infection when corticosteroids are used.

Prolonged use of corticosteroids may produce posterior subcapsular cataracts, glaucoma with possible damage to the optic nerves, and may enhance the establishment of secondary ocular infections due to fungi or viruses.

USAGE IN PREGNANCY: Since adequate human reproduction studies have not been done with corticosteroids, the use of these drugs in pregnancy, nursing mothers or women of childbearing potential requires that the possible benefits of the drug be weighed against the potential hazards to the mother and embryo or fetus.

Infants born of mothers who have received substantial doses of corticosteroids during pregnancy should be carefully observed for signs of hypoadrenalism.

Average and large doses of hydrocortisone or cortisone can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium.

These effects are less likely to occur with the synthetic derivatives except when used in large doses.

Dietary salt restriction and potassium supplementation may be necessary.

All corticosteroids increase calcium excretion.

While on corticosteroid therapy patients should not be vaccinated against smallpox.

Other immunization procedures should not be undertaken in patients who are on corticosteroids, especially on high dose, because of possible hazards of neurological complications and a lack of antibody response.

Administration of live or live, attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids.

Killed or inactivated vaccines may be administered to patients receiving immunosuppressive doses of corticosteroids; however, the response to such vaccines may be diminished.

Indicated immunization procedures may be undertaken in patients receiving nonimmunosuppressive doses of corticosteroids.

The use of prednisone in active tuberculosis should be restricted to those cases of fulminating or disseminated tuberculosis in which the corticosteroid is used for the management of the disease in conjunction with an appropriate antituberculous regimen.

If corticosteroids are indicated in patients with latent tuberculosis or tuberculin reactivity, close observation is necessary as reactivation of the disease may occur.

During prolonged corticosteroid therapy, these patients should receive chemoprophylaxis.

Persons who are on drugs which suppress the immune system are more susceptible to infections than healthy individuals.

Chickenpox and measles, for example, can have a more serious or even fatal course in non-immune children or adults on corticosteroids.

In such children or adults who have not had these diseases, particular care should be taken to avoid exposure.

How the dose, route and duration of corticosteroid administration affects the risk of developing a disseminated infection is not known.

The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known.

If exposed to chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated.

If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated.

(See the respective package inserts for complete VZIG and IG prescribing information.) If chickenpox develops, treatment with antiviral agents may be considered.

Similarly, corticosteroids should be used with great care in patients with known or suspected Stronglyoides (threadworm) infestation.

In such patients, corticosteroid-induced immunosuppression may lead to Stronglyoides hyperinfection and dissemination with widespread larval migration, often accompanied by severe enterocolitis and potentially fatal gram-negative septicemia.

DRUG INTERACTIONS

Drug Interactions The pharmacokinetic interactions listed below are potentially clinically important.

Drugs that induce hepatic enzymes such as phenobarbital, phenytoin and rifampin may increase the clearance of corticosteroids and may require increases in corticosteroid dose to achieve the desired response.

Drugs such as troleandomycin and ketoconazole may inhibit the metabolism of corticosteroids and thus decrease their clearance.

Therefore, the dose of corticosteroid should be titrated to avoid steroid toxicity.

Corticosteroids may increase the clearance of chronic high dose aspirin.

This could lead to decreased salicylate serum levels or increase the risk of salicylate toxicity when corticosteroid is withdrawn.

Aspirin should be used cautiously in conjunction with corticosteroids in patients suffering from hypoprothrombinemia.

The effect of corticosteroids on oral anticoagulants is variable.

There are reports of enhanced as well as diminished effects of anticoagulants when given concurrently with corticosteroids.

Therefore, coagulation indices should be monitored to maintain the desired anticoagulant effect.

INFORMATION FOR PATIENTS

Information for Patients: Persons who are on immunosuppressant doses of corticosteroids should be warned to avoid exposure to chickenpox or measles.

Patients should also be advised that if they are exposed, medical advice should be sought without delay.

DOSAGE AND ADMINISTRATION

: Dosage of prednisone should be individualized according to the severity of the disease and the response of the patient.

For infants and children, the recommended dosage should be governed by the same considerations rather than strict adherence to the ratio indicated by age or body weight.

Hormone therapy is an adjunct to, and not a replacement for, conventional therapy.

Dosage should be decreased or discontinued gradually when the drug has been administered for more than a few days.

The severity, prognosis, expected duration of the disease, and the reaction of the patient to medication are primary factors in determining dosage.

If a period of spontaneous remission occurs in a chronic condition, treatment should be discontinued.

Blood pressure, body weight, routine laboratory studies, including two-hour postprandial blood glucose and serum potassium, and a chest X-ray should be obtained at regular intervals during prolonged therapy.

Upper Gl X-rays are desirable in patients with known or suspected peptic ulcer disease.

The initial dosage of prednisone may vary from 5 mg to 60 mg per day, depending on the specific disease entity being treated.

In situations of less severity lower doses will generally suffice, while in selected patients higher initial doses may be required.

The initial dosage should be maintained or adjusted until a satisfactory response is noted.

If after a reasonable period of time there is a lack of satisfactory clinical response, prednisone should be discontinued and the patient transferred to other appropriate therapy.

IT SHOULD BE EMPHASIZED THAT DOSAGE REQUIREMENTS ARE VARIABLE AND MUST BE INDIVIDUALIZED ON THE BASIS OF THE DISEASE UNDER TREATMENT AND THE RESPONSE OF THE PATIENT.

After a favorable response is noted, the proper maintenance dosage should be determined by decreasing the initial drug dosage in small increments at appropriate time intervals until the lowest dosage which will maintain an adequate clinical response is reached.

It should be kept in mind that constant monitoring is needed in regard to drug dosage.

Included in the situations which may make dosage adjustment necessary are changes in clinical status secondary to remissions or exacerbations in the disease process, the patient’s individual drug responsiveness, and the effect of patient exposure to stressful situations not directly related to the disease entity under treatment; in this latter situation, it may be necessary to increase the dosage of prednisone for a period of time consistent with patient’s condition.

If after long-term therapy the drug is to be stopped, it is recommended that it be withdrawn gradually rather than abruptly.

Multiple Sclerosis In the treatment of acute exacerbations of multiple sclerosis daily doses of 200 mg of prednisolone for a week followed by 80 mg every other day for 1 month have been shown to be effective.

(Dosage range is the same for prednisone and prednisolone.) ADT® (Alternate Day Therapy) ADT is a corticosteroid dosing regimen in which twice the usual daily dose of corticoid is administered every other morning.

The purpose of this mode of therapy is to provide the patient requiring long-term pharmacologic dose treatment with the beneficial effects of corticoids while minimizing certain undesirable effects, including pituitary-adrenal suppression, the Cushingoid state, corticoid withdrawal symptoms, and growth suppression in children.

The rationale for this treatment schedule is based on two major premises: (a) the anti-inflammatory or therapeutic effect of corticoids persists longer than their physical presence and metabolic effects and (b) administration of the corticosteroid every other morning allows for re-establishment of more nearly normal hypothalamic-pituitary-adrenal (HPA) activity on the off-steroid day.

A brief review of the HPA physiology may be helpful in understanding this rationale.

Acting primarily through the hypothalamus a fall in free cortisol stimulates the pituitary gland to produce increasing amounts of corticotropin (ACTH) while a rise in free cortisol inhibits ACTH secretion.

Normally the HPA system is characterized by diurnal (circadian) rhythm.

Serum levels of ACTH rise from a low point about 10 pm to a peak level about 6 am.

Increasing levels of ACTH stimulate adrenocortical activity resulting in a rise in plasma cortisol with maximal levels occurring between 2 am and 8 am.

This rise in cortisol dampens ACTH production and in turn adrenocortical activity.

There is a gradual fall in plasma corticoids during the day with lowest levels occurring about midnight.

The diurnal rhythm of the HPA axis is lost in Cushing’s disease, a syndrome of adrenocortical hyperfunction characterized by obesity with centripetal fat distribution, thinning of the skin with easy bruisability, muscle wasting with weakness, hypertension, latent diabetes, osteoporosis, electrolyte imbalance, etc.

The same clinical findings of hyperadrenocorticism may be noted during long-term pharmacologic dose corticoid therapy administered in conventional daily divided doses.

It would appear, then, that a disturbance in the diurnal cycle with maintenance of elevated corticoid values during the night may play a significant role in the development of undesirable corticoid effects.

Escape from these constantly elevated plasma levels for even short periods of time may be instrumental in protecting against undesirable pharmacologic effects.

During conventional pharmacologic dose corticosteroid therapy, ACTH production is inhibited with subsequent suppression of cortisol production by the adrenal cortex.

Recovery time for normal HPA activity is variable depending upon the dose and duration of treatment.

During this time the patient is vulnerable to any stressful situation.

Although it has been shown that there is considerably less adrenal suppression following a single morning dose of prednisolone (10 mg) as opposed to a quarter of that dose administered every 6 hours, there is evidence that some suppressive effect on adrenal activity may be carried over into the following day when pharmacologic doses are used.

Further, it has been shown that a single dose of certain corticosteroids will produce adrenocortical suppression for two or more days.

Other corticoids, including methylprednisolone, hydrocortisone, prednisone, and prednisolone, are considered to be short acting (producing adrenocortical suppression for 1 ¼ to 1 ½ days following a single dose) and thus are recommended for alternate day therapy.

The following should be kept in mind when considering alternate day therapy: 1) Basic principles and indications for corticosteroid therapy should apply.

The benefits of ADT should not encourage the indiscriminate use of steroids.

2) ADT is a therapeutic technique primarily designed for patients in whom long-term pharmacologic corticoid therapy is anticipated.

3) In less severe disease processes in which corticoid therapy is indicated, it may be possible to initiate treatment with ADT.

More severe disease states usually will require daily divided high dose therapy for initial control of the disease process.

The initial suppressive dose level should be continued until satisfactory clinical response is obtained, usually four to ten days in the case of many allergic and collagen diseases.

It is important to keep the period of initial suppressive dose as brief as possible particularly when subsequent use of alternate day therapy is intended.

Once control has been established, two courses are available: (a) change to ADT and then gradually reduce the amount of corticoid given every day or (b) following control of the disease process reduce the daily dose of corticoid to the lowest effective level as rapidly as possible and then change over to an alternate day schedule.

Theoretically, course (a) may be preferable.

4) Because of the advantages of ADT, it may be desirable to try patients on this form of therapy who have been on daily corticoids for long periods of time (e.g., patients with rheumatoid arthritis).

Since these patients may already have a suppressed HPA axis, establishing them on ADT may be difficult and not always successful.

However, it is recommended that regular attempts be made to change them over.

It may be helpful to triple or even quadruple the daily maintenance dose and administer this every other day rather than just doubling the daily dose if difficulty is encountered.

Once the patient is again controlled, an attempt should be made to reduce this dose to a minimum.

5) As indicated above, certain corticosteroids, because of their prolonged suppressive effect on adrenal activity, are not recommended for alternate day therapy (e.g., dexamethasone and betamethasone).

6) The maximal activity of the adrenal cortex is between 2 am and 8 am, and it is minimal between 4 pm and midnight.

Exogenous corticosteroids suppress adrenocortical activity the least, when given at the time of maximal activity (am).

7) In using ADT it is important, as in all therapeutic situations to individualize and tailor the therapy to each patient.

Complete control of symptoms will not be possible in all patients.

An explanation of the benefits of ADT will help the patient to understand and tolerate the possible flare-up in symptoms which may occur in the latter part of the off-steroid day.

Other symptomatic therapy may be added or increased at this time if needed.

8) In the event of an acute flare-up of the disease process, it may be necessary to return to a full suppressive daily divided corticoid dose for control.

Once control is again established alternate day therapy may be reinstituted.

9) Although many of the undesirable features of corticosteroid therapy can be minimized by ADT, as in any therapeutic situation, the physician must carefully weigh the benefit-risk ratio for each patient in whom corticoid therapy is being considered.

Cumulative total daily doses of 1600 mcg have been tolerated, with only symptoms of gastrointestinal discomfort being reported.

In animals, the acute toxic effects are diarrhea, gastrointestinal lesions, focal cardiac necrosis, hepatic necrosis, renal tubular necrosis, testicular atrophy, respiratory difficulties, and depression of the central nervous system.

Clinical signs that may indicate an overdose are sedation, tremor, convulsions, dyspnea, abdominal pain, diarrhea, fever, palpitations, hypotension, or bradycardia.

Symptoms should be treated with supportive therapy.

It is not known if misoprostol acid is dialyzable.

However, because misoprostol is metabolized like a fatty acid, it is unlikely that dialysis would be appropriate treatment for overdosage.

DESCRIPTION

Cytotec oral tablets contain either 100 mcg or 200 mcg of misoprostol, a synthetic prostaglandin E 1 analog.

Misoprostol contains approximately equal amounts of the two diastereomers presented below with their enantiomers indicated by (±): Misoprostol is a water-soluble, viscous liquid.

Inactive ingredients of tablets are hydrogenated castor oil, hypromellose, microcrystalline cellulose, and sodium starch glycolate.

Chemical Structure

CLINICAL STUDIES

Clinical studies In a series of small short-term (about 1 week) placebo-controlled studies in healthy human volunteers, doses of misoprostol were evaluated for their ability to reduce the risk of NSAID-induced mucosal injury.

Studies of 200 mcg q.i.d.

of misoprostol with tolmetin and naproxen, and of 100 and 200 mcg q.i.d.

with ibuprofen, all showed reduction of the rate of significant endoscopic injury from about 70–75% on placebo to 10–30% on misoprostol.

Doses of 25–200 mcg q.i.d.

reduced aspirin-induced mucosal injury and bleeding.

INDICATIONS AND USAGE

Cytotec (misoprostol) is indicated for reducing the risk of NSAID (nonsteroidal anti-inflammatory drugs, including aspirin)–induced gastric ulcers in patients at high risk of complications from gastric ulcer, e.g., the elderly and patients with concomitant debilitating disease, as well as patients at high risk of developing gastric ulceration, such as patients with a history of ulcer.

Cytotec has not been shown to reduce the risk of duodenal ulcers in patients taking NSAIDs.

Cytotec should be taken for the duration of NSAID therapy.

Cytotec has been shown to reduce the risk of gastric ulcers in controlled studies of 3 months’ duration.

It had no effect, compared to placebo, on gastrointestinal pain or discomfort associated with NSAID use.

PEDIATRIC USE

Pediatric use Safety and effectiveness of Cytotec in pediatric patients have not been established.

PREGNANCY

Pregnancy: Pregnancy Category X Teratogenic effects See boxed WARNINGS .

Congenital anomalies sometimes associated with fetal death have been reported subsequent to the unsuccessful use of misoprostol as an abortifacient, but the drug’s teratogenic mechanism has not been demonstrated.

Several reports in the literature associate the use of misoprostol during the first trimester of pregnancy with skull defects, cranial nerve palsies, facial malformations, and limb defects.

Cytotec is not fetotoxic or teratogenic in rats and rabbits at doses 625 and 63 times the human dose, respectively.

Nonteratogenic effects See boxed WARNINGS .

Cytotec may endanger pregnancy (may cause abortion) and thereby cause harm to the fetus when administered to a pregnant woman.

Cytotec may produce uterine contractions, uterine bleeding, and expulsion of the products of conception.

Abortions caused by Cytotec may be incomplete.

If a woman is or becomes pregnant while taking this drug to reduce the risk of NSAID-induced ulcers, the drug should be discontinued and the patient apprised of the potential hazard to the fetus.

NUSRING MOTHERS

Nursing mothers Misoprostol is rapidly metabolized in the mother to misoprostol acid, which is biologically active and is excreted in breast milk.

There are no published reports of adverse effects of misoprostol in breast-feeding infants of mothers taking misoprostol.

Caution should be exercised when misoprostol is administered to a nursing woman.

BOXED WARNING

WARNINGS CYTOTEC (MISOPROSTOL) ADMINISTRATION TO WOMEN WHO ARE PREGNANT CAN CAUSE BIRTH DEFECTS, ABORTION, OR PREMATURE BIRTH.

UTERINE RUPTURE HAS BEEN REPORTED WHEN CYTOTEC WAS ADMINISTERED IN PREGNANT WOMEN TO INDUCE LABOR OR TO INDUCE ABORTION BEYOND THE EIGHTH WEEK OF PREGNANCY (see also PRECAUTIONS and LABOR AND DELIVERY ).

CYTOTEC SHOULD NOT BE TAKEN BY PREGNANT WOMEN TO REDUCE THE RISK OF ULCERS INDUCED BY NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs) (see CONTRAINDICATIONS , WARNINGS , and PRECAUTIONS ).

PATIENTS MUST BE ADVISED OF THE ABORTIFACIENT PROPERTY AND WARNED NOT TO GIVE THE DRUG TO OTHERS.

Cytotec should not be used for reducing the risk of NSAID-induced ulcers in women of childbearing potential unless the patient is at high risk of complications from gastric ulcers associated with use of the NSAID, or is at high risk of developing gastric ulceration.

In such patients, Cytotec may be prescribed if the patient • has had a negative serum pregnancy test within 2 weeks prior to beginning therapy.

• is capable of complying with effective contraceptive measures.

• has received both oral and written warnings of the hazards of misoprostol, the risk of possible contraception failure, and the danger to other women of childbearing potential should the drug be taken by mistake.

• will begin Cytotec only on the second or third day of the next normal menstrual period.

INFORMATION FOR PATIENTS

Information for patients Women of childbearing potential using Cytotec to decrease the risk of NSAID-induced ulcers should be told that they must not be pregnant when Cytotec therapy is initiated, and that they must use an effective contraception method while taking Cytotec.

See boxed WARNINGS .

Cytotec is intended for administration along with nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin, to decrease the chance of developing an NSAID-induced gastric ulcer.

Cytotec should be taken only according to the directions given by a physician.

If the patient has questions about or problems with Cytotec, the physician should be contacted promptly.

THE PATIENT SHOULD NOT GIVE CYTOTEC TO ANYONE ELSE.

Cytotec has been prescribed for the patient’s specific condition, may not be the correct treatment for another person, and may be dangerous to the other person if she were to become pregnant.

The Cytotec package the patient receives from the pharmacist will include a leaflet containing patient information.

The patient should read the leaflet before taking Cytotec and each time the prescription is renewed because the leaflet may have been revised.

Keep Cytotec out of the reach of children.

SPECIAL NOTE FOR WOMEN: Cytotec may cause birth defects, abortion (sometimes incomplete), or premature labor if given to pregnant women.

Cytotec is available only as a unit-of-use package that includes a leaflet containing patient information.

See Patient Information at the end of this labeling.

DOSAGE AND ADMINISTRATION

The recommended adult oral dose of Cytotec for reducing the risk of NSAID-induced gastric ulcers is 200 mcg four times daily with food.

If this dose cannot be tolerated, a dose of 100 mcg can be used.

(See Clinical Pharmacology: Clinical studies .) Cytotec should be taken for the duration of NSAID therapy as prescribed by the physician.

Cytotec should be taken with a meal, and the last dose of the day should be at bedtime.

Renal impairment Adjustment of the dosing schedule in renally impaired patients is not routinely needed, but dosage can be reduced if the 200-mcg dose is not tolerated.

DRUG INTERACTIONS

7 Consult the labeling of all concurrently-used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations .

Drugs or herbal products that induce certain enzymes (for example, CYP3A4) may decrease the effectiveness of COCs or increase breakthrough bleeding.

Counsel patients to use a back-up or alternative method of contraception when enzyme inducers are used with COCs.

( 7.1 ) 7.1 Effects of Other Drugs on Combined Oral Contraceptives Substances diminishing the efficacy of COCs: Dienogest is a substrate of CYP3A4.

Women who take medications that are strong CYP3A4 inducers should not choose Natazia as their oral contraceptive while using these inducers and for at least 28 days after discontinuation of these inducers due to the possibility of increased breakthrough bleeding and/or decreased contraceptive efficacy.

Drugs or herbal products that induce certain enzymes, including CYP3A4, may decrease the effectiveness of COCs or increase breakthrough bleeding.

Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include phenytoin, barbiturates, carbamazepine, bosentan, felbamate, griseofulvin, oxcarbazepine, rifampin, topiramate and products containing St.

John’s wort.

Interactions between oral contraceptives and other drugs may lead to breakthrough bleeding and/or contraceptive failure.

Counsel women to use an alternative method of contraception or a back-up method when enzyme inducers are used with COCs, and to continue back-up contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability.

Multiple dose co-administration of the strong CYP3A4 inducer rifampin with estradiol valerate/dienogest tablets in healthy postmenopausal women led to a decrease in dienogest and estradiol systemic exposure at steady state.

[See Clinical Pharmacology (12.3).] Substances Increasing the Systemic Exposure of COCs (enzyme inhibitors): Concomitant administration of moderate or strong CYP3A4 inhibitors like azole antifungals (for example, ketoconazole, itraconazole, voriconazole, fluconazole), verapamil, macrolides (for example, clarithromycin, erythromycin), diltiazem, and grapefruit increase the serum concentrations of both estradiol and dienogest.

In a multiple dose study investigating the effect of CYP3A4 inhibitors (ketoconazole and erythromycin) on Natazia, steady state estradiol and dienogest exposures were increased when co-administered with ketoconazole or erythromycin [see Clinical Pharmacology 12.3] .

Human Immunodeficiency Virus (HIV)/Hepatitis C Virus (HCV) Protease Inhibitors and Non-Nucleoside Reverse Transcriptase Inhibitors : Significant changes (increase and decrease) in plasma concentrations of estrogen and progestin have been noted in some cases of co-administration of HIV/HCV protease inhibitors or with non-nucleoside reverse transcriptase inhibitors.

Antibiotics : There have been reports of pregnancy while taking hormonal contraceptives and antibiotics, but clinical pharmacokinetic studies have not shown consistent effects of antibiotics on plasma concentrations of synthetic steroids.

7.2 Effects of Combined Oral Contraceptives on Other Drugs COCs containing ethinyl estradiol may inhibit the metabolism of other compounds.

COCs have been shown to significantly decrease plasma concentrations of lamotrigine, likely due to induction of lamotrigine glucuronidation.

This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary.

Consult the labeling of the concurrently-used drug to obtain further information about interactions with COCs or the potential for enzyme alterations.

[See Clinical Pharmacology ( 12.3 ).] In vitro studies with human CYP enzymes did not indicate an inhibitory potential of dienogest at clinically relevant concentrations.

Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentrations of thyroid-binding globulin increase with use of COCs.

7.3 Interference with Laboratory Tests The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins [see Warnings and Precautions ( 5.11 ) and Drug Interactions ( 7.2 )].

OVERDOSAGE

10 There have been no reports of serious ill effects from overdose, including ingestion by children.

Overdosage may cause withdrawal bleeding in females and nausea.

CLINICAL STUDIES

14 14.1 Oral Contraceptive Clinical Trials The study conducted in North America (U.S.

and Canada) was a multicenter, open-label, single-arm, unintended pregnancy study.

There were 490 healthy subjects between 18 and 35 years of age (mean age: 25.1 years) who were treated for up to 28 cycles of 28 days each.

The racial demographic of enrolled women was: Caucasian (76%), Hispanic (13%), African-American (7%), Asian (3%), and Other (1%).

The weight range for treated women was 40 to 100 kg (mean weight: 62.5 kg) and the BMI range was 14 to 30 kg/m 2 (mean BMI: 23.3 kg/m 2 ).

Of treated women, 15% discontinued the study treatment due to an adverse event, 13% were lost to follow up, 10% withdrew their consent, 8% discontinued due to other reason, 1% discontinued due to protocol deviation, and 1% discontinued due to pregnancy.

The study conducted in Europe (Germany, Austria and Spain) was a multicenter, open-label, single-arm contraceptive reliability study.

There were 1,377 healthy subjects between 18 and 50 years of age (mean age: 30.3 years) who were treated for 20 cycles of 28 days each.

The racial demographic of enrolled women was predominantly Caucasian (99.2%).

The weight range for treated women was 38 to 98 kg (mean weight: 63.8 kg) and the BMI range was 15 to 31.8 kg/m 2 (mean BMI: 22.8 kg/m 2 ).

Of treated women, 10% discontinued the study treatment due to an adverse event, 5% discontinued due to other reason, 2% were lost to follow up, 2% discontinued due to protocol deviation, 2% withdrew their consent, and 1% discontinued due to pregnancy.

The Pearl Index (PI) was the primary efficacy endpoint used to assess contraceptive reliability and was assessed in each of the two studies, assuming all subjects were at risk of pregnancy in all medication cycles unless back-up contraception was documented.

The PI is based on pregnancies that occurred after the onset of treatment and within 7 days after the last pill intake.

Cycles in which conception did not occur, but which included the use of back-up contraception, were not included in the calculation of the PI.

The PI also includes patients who did not take the drug correctly.

The estimated PI for the North American study is 1.64 and the estimated PI for the European study is 1.04.

The Kaplan-Meier method was also used to calculate the contraceptive failure rate.

The summary of the Pearl Indexes and cumulative contraceptive failure rates are provided in Table 2: Table 2 Summary of the Pearl Indexes and the Cumulative Contraceptive Failure Rates Study Age Group Relative Treatment Exposure Cycles Total treatment exposure time without back-up contraception Number of Pregnancies within 13 Cycles and 7 Days after Last Treatment Pearl Index Upper Limit of 95% CI Contraceptive Failure Rate at the End of First Year North America 18–35 3,969 5 1.64 3.82 0.016 Europe 18–35 11,275 9 1.04 1.97 0.010 14.2 Heavy Menstrual Bleeding Clinical Trials The efficacy and safety of Natazia were evaluated in two multi-regional, multicenter, double-blind, randomized, placebo-controlled clinical trials.

Study 308960 was performed in the United States and Canada and Study 308961 was performed in Australia and 9 European countries.

The studies were identical in design.

The studies enrolled women, 18 years of age or older, with a diagnosis of dysfunctional uterine bleeding characterized as heavy, prolonged and/or frequent bleeding without organic pathology.

Heavy menstrual bleeding (HMB) was defined as menstrual blood loss of 80 mL or more in at least 2 bleeding episodes.

The diagnosis of HMB was documented through the collection of used sanitary protection (pads and tampons) to quantify blood loss assessed by the alkaline hematin method.

Overall, about 85% of the subjects qualified for the study because they had heavy menstrual bleeding symptoms.

A total of 421 women with a mean age of 38.2 and a mean BMI of 25.5 were randomized to the two clinical studies, for a total of 269 women in the Natazia group and 152 women in the placebo group, and treated for seven 28-day cycles.

Approximately 81% were Caucasian, 13% were Black, and 6% were Hispanic or Asian or Other.

The primary efficacy variable was the proportion of subjects who were completely relieved of symptoms, which was defined by the number of subjects with the absence of any dysfunctional bleeding symptom and who met up to 8 strictly defined criteria for success during the 90-day efficacy assessment phase.

In Study 308960, the proportion of the intent-to-treat subjects with complete symptom relief was 29.2% in the Natazia group compared to 2.9% in the placebo group.

In Study 308961, the proportion of the intent-to-treat subjects with complete symptom relief was 29.5% in the Natazia group compared to 1.2% in the placebo group.

In both studies, Natazia was effective in treating the symptoms of HMB in the subset of women who entered the study with symptoms specific to HMB.

Among patients with HMB, menstrual blood loss (MBL) was statistically significantly reduced in the group treated with Natazia compared with placebo (p<0.0001 for both studies).

Evaluating data based on 28-day cycles, the median menstrual blood volume at Cycle 7 was reduced from the baseline median by 90% in one trial and 87% in the other.

For women treated with placebo, the median menstrual blood volume at Cycle 7 was reduced from the baseline median by 14% and 32% in the two trials, respectively.

Figures 1 and 2 display the MBL volume by cycle and by study.

MECHANISM OF ACTION

12.1 Mechanism of Action COCs lower the risk of becoming pregnant primarily by suppressing ovulation.

Other possible mechanisms may include cervical mucus changes that inhibit sperm penetration and endometrial changes that reduce the likelihood of implantation.

INDICATIONS AND USAGE

1 • Natazia is an estrogen/progestin COC indicated for use by women to prevent pregnancy.

( 1 ) • Treatment of heavy menstrual bleeding in women without organic pathology who choose to use an oral contraceptive as their method of contraception.

( 1.2 ) • The efficacy of Natazia in women with a body mass index (BMI) of >30 kg/m 2 has not been evaluated.

( 1 , 8.8 ) 1.1 Oral Contraception Natazia ® is indicated for use by women to prevent pregnancy.

The efficacy of Natazia in women with a body mass index (BMI) of > 30 kg/m 2 has not been evaluated.

1.2 Heavy Menstrual Bleeding Natazia is also indicated for the treatment of heavy menstrual bleeding in women without organic pathology who choose to use an oral contraceptive as their method of contraception [see Clinical Studies ( 14.2 )].

PEDIATRIC USE

8.4 Pediatric Use Safety and efficacy of Natazia have been established in women of reproductive age.

Efficacy is expected to be the same for postpubertal adolescents under the age of 18 and for users 18 years and older.

Use of this product before menarche is not indicated.

PREGNANCY

8.1 Pregnancy There is little or no increased risk of birth defects in women who inadvertently use COCs during early pregnancy.

Epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to low dose COCs prior to conception or during early pregnancy.

The administration of COCs to induce withdrawal bleeding should not be used as a test for pregnancy.

COCs should not be used during pregnancy to treat threatened or habitual abortion.

Women who do not breastfeed may start COCs no earlier than four weeks postpartum.

NUSRING MOTHERS

8.3 Nursing Mothers When possible, advise the nursing mother to use other forms of contraception until she has weaned her child.

Estrogen-containing COCs can reduce milk production in breastfeeding mothers.

This is less likely to occur once breastfeeding is well-established; however, it can occur at any time in some women.

Small amounts of oral contraceptive steroids and/or metabolites are present in breast milk.

BOXED WARNING

WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptives (COC) use.

This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked.

For this reason, COCs should not be used by women who are over 35 years of age and smoke.

[See Contraindications ( 4 ).] WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS See full prescribing information for complete boxed warning.

• Women over 35 years old who smoke should not use Natazia.

( 4 ) • Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive (COC) use.

WARNING AND CAUTIONS

5 WARNINGS AND PRECAUTIONS • Vascular risks : Stop Natazia if a thrombotic event occurs.

Stop Natazia at least 4 weeks before and through 2 weeks after major surgery.

Start Natazia no earlier than 4 weeks after delivery, in women who are not breastfeeding.

( 5.1 ) • Liver disease : Discontinue Natazia if jaundice occurs.

( 5.3 ) • High blood pressure : Do not prescribe Natazia for women with uncontrolled hypertension or hypertension with vascular disease.

( 5.4 ) • Carbohydrate and lipid metabolic effects : Monitor prediabetic and diabetic women taking Natazia.

Consider an alternate contraceptive method for women with uncontrolled dyslipidemia.

( 5.6 ) • Headache : Evaluate significant change in headaches and discontinue Natazia if indicated.

( 5.7 ) • Uterine bleeding : Evaluate irregular bleeding or amenorrhea.

( 5.8 ) • CYP3A4 induction : Women taking strong CYP3A4 inducers (for example, carbamazepine, phenytoin, rifampicin, and St.

John’s wort) should not choose Natazia as their oral contraceptive due to the possibility of decreased contraceptive efficacy.

( 5.13 , 7.1 ) 5.1 Thromboembolic Disorders and Other Vascular Problems Stop Natazia if an arterial or venous thrombotic event (VTE) occurs.

The use of COCs increases the risk of venous thromboembolism.

However, pregnancy increases the risk of venous thromboembolism as much or more than the use of COCs.

The risk of VTE in women using COCs has been estimated to be 3 to 9 per 10,000 woman-years.

The risk of VTE is highest during the first year of use.

Data from a large, prospective cohort safety study of various COCs suggest that this increased risk, as compared to that in non-COC users, is greatest during the first 6 months of COC use.

Data from this safety study indicate that the greatest risk of VTE is present after initially starting a COC or restarting (following a 4 week or greater pill-free interval) the same or a different COC.

Use of COCs also increases the risk of arterial thromboses such as strokes and myocardial infarctions, especially in women with other risk factors for these events.

The risk of thromboembolic disease due to oral contraceptives gradually disappears after COC use is discontinued.

If feasible, stop Natazia at least 4 weeks before and through 2 weeks after major surgery or other surgeries known to have an elevated risk of thromboembolism.

Start Natazia no earlier than 4 weeks after delivery, in women who are not breastfeeding.

The risk of postpartum thromboembolism decreases after the third postpartum week, whereas the risk of ovulation increases after the third postpartum week.

COCs have been shown to increase both the relative and attributable risks of cerebrovascular events (thrombotic and hemorrhagic strokes), although, in general, the risk is greatest among older (>35 years of age), hypertensive women who also smoke.

COCs also increase the risk for stroke in women with other underlying risk factors.

Oral contraceptives must be used with caution in women with cardiovascular disease risk factors.

Stop Natazia if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions.

Evaluate for retinal vein thrombosis immediately.

[See Adverse Reactions ( 6 ).] 5.2 Malignant Neoplasms Breast Cancer Natazia is contraindicated in females who currently have or have had breast cancer because breast cancer may be hormonally sensitive [see Contraindications ( 4 )].

Epidemiology studies have not found a consistent association between use of combined oral contraceptives (COCs) and breast cancer risk.

Studies do not show an association between ever (current or past) use of COCs and risk of breast cancer.

However, some studies report a small increase in the risk of breast cancer among current or recent users (<6 months since last use) and current users with longer duration of COC use [see Adverse Reactions ( 6.2 )] .

Cervical Cancer Some studies suggest that COCs are associated with an increase in the risk of cervical cancer or intraepithelial neoplasia.

However, there is controversy about the extent to which these findings may be due to differences in sexual behavior and other factors.

5.3 Liver Disease Discontinue Natazia if jaundice develops.

Steroid hormones may be poorly metabolized in patients with impaired liver function.

Acute or chronic disturbances of liver function may necessitate the discontinuation of COC use until markers of liver function return to normal and COC causation has been excluded.

Hepatic adenomas are associated with COC use.

An estimate of the attributable risk is 3.3 cases/100,000 COC users.

Rupture of hepatic adenomas may cause death through intra-abdominal hemorrhage.

Studies have shown an increased risk of developing hepatocellular carcinoma in long-term (> 8 years) COC users.

However, the attributable risk of liver cancers in COC users is less than one case per million users.

Oral contraceptive-related cholestasis may occur in women with a history of pregnancy-related cholestasis.

Women with a history of COC-related cholestasis may have the condition recur with subsequent COC use.

5.4 High Blood Pressure For women with well-controlled hypertension, monitor blood pressure and stop Natazia if blood pressure rises significantly.

Women with uncontrolled hypertension or hypertension with vascular disease should not use COCs.

An increase in blood pressure has been reported in women taking COCs, and this increase is more likely in older women and with extended duration of use.

The incidence of hypertension increases with increasing concentration of progestin.

5.5 Gallbladder Disease Studies suggest a small increased relative risk of developing gallbladder disease among COC users.

5.6 Carbohydrate and Lipid Metabolic Effects Carefully monitor prediabetic and diabetic women who are taking Natazia.

COCs may decrease glucose tolerance in a dose-related fashion.

Consider alternative contraception for women with uncontrolled dyslipidemia.

A small proportion of women will have adverse lipid changes while on COCs.

Women with hypertriglyceridemia, or a family history thereof, may be at an increased risk of pancreatitis when using COCs.

5.7 Headache If a woman taking Natazia develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue Natazia if indicated.

An increase in frequency or severity of migraine during COC use (which may be prodromal of a cerebrovascular event) may be a reason for immediate discontinuation of the COC.

5.8 Bleeding Irregularities Breakthrough bleeding and spotting sometimes occur in patients on COCs, especially during the first three months of use.

If bleeding persists or occurs after previously regular cycles, check for causes such as pregnancy or malignancy.

If pathology and pregnancy are excluded, bleeding irregularities may resolve over time or with a change to a different COC.

Women who are not pregnant and use Natazia, may experience amenorrhea.

Based on patient diaries, amenorrhea occurs in approximately 16% of cycles in women using Natazia.

Pregnancy should be ruled out in the event of amenorrhea occurring in two or more consecutive cycles.

Some women may encounter amenorrhea or oligomenorrhea after stopping COCs, especially when such a condition was pre-existent.

Based on patient diaries from three clinical trials evaluating the safety and efficacy of Natazia for contraception, 10-23% of women experienced intracyclic bleeding per cycle.

5.9 COC Use Before or During Early Pregnancy Extensive epidemiological studies have revealed no increased risk of birth defects in women who have used oral contraceptives prior to pregnancy.

Studies also do not suggest a teratogenic effect, particularly in so far as cardiac anomalies and limb-reduction defects are concerned, when taken inadvertently during early pregnancy.

Oral contraceptive use should be discontinued if pregnancy is confirmed.

The administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy [see Use in Specific Populations ( 8.1 )] .

5.10 Depression Women with a history of depression should be carefully observed and Natazia discontinued if depression recurs to a serious degree .

5.11 Interference with Laboratory Tests The use of COCs may change the results of some laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.

Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentrations of thyroid-binding globulin increase with use of COCs [see Clinical Pharmacology ( 12.3 )] .

5.12 Monitoring A woman who is taking COCs should have a yearly visit with her healthcare provider for a blood pressure check and for other indicated healthcare.

5.13 Drug Interactions Women who take medications that are strong cytochrome P450 3A4 (CYP3A4) inducers (for example, carbamazepine, phenytoin, rifampicin, and St.

John’s wort) should not choose Natazia as their oral contraceptive while using these inducers and for at least 28 days after discontinuation of these inducers due to the possibility of decreased contraceptive efficacy [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 )].

5.14 Other Conditions In women with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema.

Chloasma may occasionally occur, especially in women with a history of chloasma gravidarum.

Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation while taking COCs.

INFORMATION FOR PATIENTS

17 PATIENT COUNSELING INFORMATION See “FDA-approved patient labeling (Patient Information).” • Counsel patients that cigarette smoking increases the risk of serious cardiovascular events from COC use, and that women who are over 35 years old and smoke should not use COCs.

• Counsel patients that the increased risk of VTE compared to non-users of COCs is greatest after initially starting a COC or restarting (following a 4 week or greater pill-free interval) the same or a different COC.

• Counsel patients that Natazia does not protect against HIV infection (AIDS) and other sexually transmitted diseases.

• Counsel patients on Warnings and Precautions associated with COCs.

• Inform patients that Natazia is not indicated during pregnancy.

If pregnancy occurs during treatment with Natazia, instruct the patient to stop further intake.

• Counsel patients to take one tablet daily by mouth at the same time every day in the exact order noted on the blister.

Instruct patients what to do in the event pills are missed.

See What Should I Do if I Miss any Pills section in FDA-Approved Patient Labeling.

• Counsel women who are taking strong CYP3A4 inducers (for example, carbamazepine, phenytoin, rifampicin, and St.

John’s wort) not to choose Natazia as their oral contraceptive due to the possibility of decreased contraceptive efficacy.

• Counsel patients to use a back-up or alternative method of contraception when weak or moderate enzyme inducers are used with Natazia.

• Counsel patients who are breastfeeding or who desire to breastfeed that COCs may reduce breast milk production.

This is less likely to occur if breastfeeding is well established.

• Counsel any patient who starts COCs postpartum, and who has not yet had a period, to use an additional method of contraception until she has taken Natazia for 9 consecutive days.

• Counsel patients that amenorrhea may occur.

Rule out pregnancy in the event of amenorrhea in two or more consecutive cycles.

DOSAGE AND ADMINISTRATION

2 • Take one tablet daily by mouth at the same time every day.

( 2.1 ) • Tablets must be taken in the order directed on the blister pack.

( 2.1 ) • Do not skip or delay intake by more than 12 hours.

( 2.1 ) 2.1 How to Take Natazia To achieve maximum contraceptive effectiveness, Natazia must be taken exactly as directed.

Take one tablet by mouth at the same time every day.

Tablets must be taken in the order directed on the blister pack.

Tablets should not be skipped or intake delayed by more than 12 hours.

For patient instructions for missed pills, see FDA-Approved Patient Labeling.

2.2 How to Start Natazia Instruct the patient to begin taking Natazia on Day 1 of her menstrual cycle (that is, the first day of her menstrual bleeding).

See FDA-Approved Patient Labeling .

Instruct the patient to use a non-hormonal contraceptive as back-up during the first 9 days.

For postpartum women who do not breastfeed or after a second trimester abortion, start Natazia no earlier than 4 weeks postpartum due to the increased risk of thromboembolism.

If the patient starts on Natazia postpartum and has not yet had a period, evaluate for possible pregnancy, and instruct her to use an additional method of contraception until she has taken Natazia for 9 consecutive days.

The possibility of ovulation and conception prior to initiation of medication should also be considered.

If the patient is switching from a combination hormonal method such as: • Another pill • Vaginal ring • Patch • Instruct her to take the first dark yellow pill on the first day of her withdrawal bleed.

She should not continue taking the pills from her previous birth control pack.

If she does not have a withdrawal bleed, rule out pregnancy before starting Natazia.

• If she previously used a vaginal ring or transdermal patch, she should start using Natazia on the day the ring or patch is removed.

• Instruct the patient to use a non-hormonal back-up method such as a condom or spermicide for the first 9 days.

If the patient is switching from a progestin-only method such as a: • Progestin-only pill • Implant • Intrauterine system • Injection • Instruct her to take the first dark yellow pill on the day she would have taken her next progestin-only pill or on the day of removal of her implant or intrauterine system or on the day when she would have had her next injection.

• Instruct the patient to use a non-hormonal back-up method such as a condom or spermicide for the first 9 days.

2.3 Advice in Case of Gastrointestinal Disturbances In case of severe vomiting or diarrhea, absorption may not be complete and additional contraceptive measures should be taken.

If vomiting or diarrhea occurs within 3-4 hours after taking a colored tablet, this can be regarded as a missed tablet.

Thiamine hydrochloride 100 MG/ML Injectable Solution

Generic Name: THIAMINE HYDROCHLORIDE
Brand Name: Thiamine Hydrochloride
  • Substance Name(s):
  • THIAMINE HYDROCHLORIDE

WARNINGS

WARNING: This product contains aluminum that may be toxic.

Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired.

Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity.

Tissue loading may occur at even lower rates of administration.

Serious hypersensitivity/anaphylactic reactions can occur, especially after repeated administration.

Deaths have resulted from IV or IM administration of thiamine (see ADVERSE REACTIONS ).

Routine testing for hypersensitivity, in many cases, may not detect hypersensitivity.

Nevertheless, a skin test should be performed on patients who are suspected of drug allergies or previous reactions to thiamine, and any positive responders should not receive thiamine by injection.

If hypersensitivity to thiamine is suspected (based on history of drug allergy or occurrence of adverse reactions after thiamine administration), administer one-hundredth of the dose intradermally and observe for 30 minutes.

If no reaction occurs, full dose can be given; the patient should be observed for at least 30 minutes after injection.

Be prepared to treat anaphylactic reactions regardless of the precautions taken.

Treatment of anaphylactic reactions includes maintaining a patent airway and the use of epinephrine, oxygen, vasopressors, steroids and antihistamines.

OVERDOSAGE

Parenteral doses of 100 mg to 500 mg singly have been administered without toxic effects.

However, dosages exceeding 30 mg 3 times a day are not utilized effectively.

When the body tissues are saturated with thiamine, it is excreted in the urine as pyrimidine.

As the intake of thiamine is further increased, it appears unchanged in the urine.

INDICATIONS AND USAGE

Thiamine hydrochloride injection is effective for the treatment of thiamine deficiency or beriberi whether of the dry (major symptoms related to the nervous system) or wet (major symptoms related to the cardiovascular system) variety.

Thiamine hydrochloride injection should be used where rapid restoration of thiamine is necessary, as in Wernicke’s encephalopathy, infantile beriberi with acute collapse, cardiovascular disease due to thiamine deficiency, or neuritis of pregnancy if vomiting is severe.

It is also indicated when giving IV dextrose to individuals with marginal thiamine status to avoid precipitation of heart failure.

Thiamine hydrochloride injection is also indicated in patients with established thiamine deficiency who cannot take thiamine orally due to coexisting severe anorexia, nausea, vomiting, or malabsorption.

Thiamine hydrochloride injection is not usually indicated for conditions of decreased oral intake or decreased gastrointestinal absorption, because multiple vitamins should usually be given.

PREGNANCY

Usage in Pregnancy Studies in pregnant women have not shown that thiamine hydrochloride increases the risk of fetal abnormalities if administered during pregnancy.

If the drug is used during pregnancy, the possibility of fetal harm appears remote.

Because studies cannot rule out the possibility of harm however, thiamine hydrochloride should be used during pregnancy only if clearly needed.

NUSRING MOTHERS

Nursing Mothers It is not known whether this drug is excreted in human milk.

Because many drugs are excreted in human milk, caution should be exercised when thiamine hydrochloride is administered to a nursing mother.

INFORMATION FOR PATIENTS

Information for Patients The patient should be advised as to proper dietary habits during treatment so that relapses will be less likely to occur with reduction in dosage or cessation of injection therapy.

DOSAGE AND ADMINISTRATION

“Wet” beriberi with myocardial failure must be treated as an emergency cardiac condition, and thiamine must be administered slowly by the IV route in this situation (see WARNINGS ).

In the treatment of beriberi, 10 mg to 20 mg of thiamine hydrochloride are given IM 3 times daily for as long as 2 weeks.

(See WARNINGS regarding repeated injection of thiamine.) An oral therapeutic multivitamin preparation containing 5 mg to 10 mg thiamine, administered daily for one month, is recommended to achieve body tissue saturation.

Infantile beriberi that is mild may respond to oral therapy, but if collapse occurs, doses of 25 mg may cautiously be given IV.

Poor dietary habits should be corrected and an abundant and well-balanced dietary intake should be prescribed.

Patients with neuritis of pregnancy in whom vomiting is severe enough to preclude adequate oral therapy should receive 5 mg to 10 mg of thiamine hydrochloride IM daily.

In the treatment of Wernicke-Korsakoff syndrome, thiamine hydrochloride has been administered IV in an initial dose of 100 mg, followed by IM doses of 50 mg to 100 mg daily until the patient is consuming a regular, balanced diet.

(See WARNINGS regarding repeated injections of thiamine.) Patients with marginal thiamine status to whom dextrose is being administered should receive 100 mg thiamine hydrochloride in each of the first few liters of IV fluid to avoid precipitating heart failure.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
