Drugs That Interfere with Hemostasis Following coadministration of stable doses of warfarin (1 to 10 mg/day) with multiple daily doses of TRINTELLIX, no significant effects were observed in INR, prothrombin values or total warfarin (protein bound plus free drug) pharmacokinetics for both R- and S-warfarin.
Coadministration of aspirin 150 mg/day with multiple daily doses of TRINTELLIX had no significant inhibitory effect on platelet aggregation or pharmacokinetics of aspirin and salicylic acid [see Clinical Pharmacology (12.3) ] .
Patients receiving other drugs that interfere with hemostasis should be carefully monitored when TRINTELLIX is initiated or discontinued [see Warnings and Precautions (5.3) , Drug Interactions (7.1) ] .
Highly Protein Bound Drugs In a clinical study with coadministration of TRINTELLIX (10 mg/day) and warfarin (1 mg/day to 10 mg/day), a highly protein bound drug, no significant change in INR was observed [see Drug Interactions (7.1) , Clinical Pharmacology (12.3) ] .
7.3 Interference with Urine Enzyme Immunoassays for Methadone False positive results in urine enzyme immunoassays for methadone have been reported in patients who have taken vortioxetine.
An alternative analytical technique (e.g., chromatographic methods) should be considered to confirm positive methadone urine drug screen results.
OVERDOSAGE
10 10.1 Human Experience There is limited clinical trial experience regarding human overdosage with TRINTELLIX.
In premarketing clinical studies, cases of overdose were limited to patients who accidentally or intentionally consumed up to a maximum dose of 40 mg of TRINTELLIX.
The maximum single dose tested was 75 mg in men.
Ingestion of TRINTELLIX in the dose range of 40 to 75 mg was associated with increased rates of nausea, dizziness, diarrhea, abdominal discomfort, generalized pruritus, somnolence, and flushing.
There have been postmarketing reports of overdoses of TRINTELLIX.
The most frequently reported symptoms with overdoses up to 80 mg (four times the maximum recommended daily dose) were nausea and vomiting.
With overdoses greater than 80 mg, a case of serotonin syndrome in combination with another serotonergic drug, and a case of seizure, have been reported.
10.2 Management of Overdose No specific antidotes for TRINTELLIX are known.
In managing overdosage, consider the possibility of multiple drug involvement.
In case of overdose, call Poison Control Center at 1-800-222-1222 for latest recommendations.

Chemical Structure
CLINICAL STUDIES
14 The efficacy of TRINTELLIX in treatment for MDD was established in six, 6 to 8 week randomized, double-blind, placebo-controlled, fixed-dose studies (including one study in the elderly) and one maintenance study in adult inpatients and outpatients who met the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria for MDD.
Adults (aged 18 years to 75 years) The efficacy of TRINTELLIX in patients aged 18 years to 75 years was demonstrated in five, 6 to 8 week, placebo-controlled studies (Studies 1 to 5 in Table 5 ).
In these studies, patients were randomized to TRINTELLIX 5 mg, 10 mg, 15 mg or 20 mg or placebo once daily.
For patients who were randomized to TRINTELLIX 15 mg/day or 20 mg/day, the final doses were titrated up from 10 mg/day after the first week.
The primary efficacy measures were the Hamilton Depression Scale (HAMD-24) total score in Study 2 and the Montgomery-Asberg Depression Rating Scale (MADRS) total score in all other studies.
In each of these studies, at least one dose group of TRINTELLIX was superior to placebo in improvement of depressive symptoms as measured by mean change from baseline to endpoint visit on the primary efficacy measurement (see Table 5 ) .
Subgroup analysis by age, gender or race did not suggest any clear evidence of differential responsiveness.
Two studies of the 5 mg dose in the U.S.
(not represented in Table 5 ) failed to show effectiveness.
Elderly Study (aged 64 years to 88 years) The efficacy of TRINTELLIX for the treatment of MDD was also demonstrated in a randomized, double-blind, placebo-controlled, fixed-dose study of TRINTELLIX in elderly patients (aged 64 years to 88 years) with MDD (Study 6 in Table 5 ).
Patients meeting the diagnostic criteria for recurrent MDD with at least one previous major depressive episode before the age of 60 years and without comorbid cognitive impairment (Mini Mental State Examination score <24) received TRINTELLIX 5 mg or placebo.

Time Course of Treatment Response In the 6 to 8 week placebo-controlled studies, an effect of TRINTELLIX based on the primary efficacy measure was generally observed starting at Week 2 and increased in subsequent weeks with the full antidepressant effect of TRINTELLIX generally not seen until Study Week 4 or later.
Figure 4 depicts time course of response in U.S.
based on the primary efficacy measure (MADRS) in Study 5.

In Studies 1 and 6, the primary analysis was not based on MMRM and in Studies 2 and 6 the primary efficacy measure was not based on MADRS Figure 4 Figure 5 Digit Symbol Substitution Test in Major Depressive Disorder Two, eight week, randomized, double-blind, placebo-controlled studies were conducted to evaluate the effect of TRINTELLIX on the Digit Symbol Substitution Test (DSST) during the treatment of acute MDD.
The DSST is a neuropsychological test that most specifically measures processing speed, an aspect of cognitive function that may be impaired in MDD.
Patients are asked to match nine symbols with their corresponding number (1 to 9) according to a key; the score is the correct number of matches achieved in 90 seconds.
For reference, the mean score for healthy 45 to 54 year-old subjects is 50 (SD=15).
Study 7 randomized adult patients meeting the diagnostic criteria for recurrent MDD to receive TRINTELLIX 10 mg, TRINTELLIX 20 mg, or placebo once daily.
Study 8 randomized adult patients meeting the diagnostic criteria for recurrent MDD and reporting subjective difficulty concentrating or slow thinking to receive a flexible dose of TRINTELLIX (10 or 20 mg) or placebo once daily.
Neither study included patients whose MDD was in remission yet who continued to experience difficulty concentrating or slow thinking.
Patients’ mean age was 46 (SD=12) and 45 (SD=12) in Study 7 and 8, respectively.
In both studies, patients in the TRINTELLIX group had a statistically significantly greater improvement in number of correct responses on the DSST (Table 6) ; depressed mood as assessed by change from baseline in MADRS total score also improved in both studies.

Maintenance Studies In a non-US maintenance study (Study 9 in Figure 6 ), 639 patients meeting DSM-IV-TR criteria for MDD received flexible doses of TRINTELLIX (5 mg or 10 mg) once daily during an initial 12 week open-label treatment phase; the dose of TRINTELLIX was fixed during Weeks 8 to 12.
Three hundred ninety six (396) patients who were in remission (MADRS total score ≤10 at both Weeks 10 and 12) after open-label treatment were randomly assigned to continuation of a fixed dose of TRINTELLIX at the final dose they responded to (about 75% of patients were on 10 mg/day) during the open-label phase or to placebo for 24 to 64 weeks.
Approximately 61% of randomized patients satisfied remission criterion (MADRS total score ≤10) for at least four weeks (since Week 8), and 15% for at least eight weeks (since Week 4).
Patients on TRINTELLIX experienced a statistically significantly longer time to have recurrence of depressive episodes than did patients on placebo.
Recurrence of depressive episode was defined as a MADRS total score ≥22 or lack of efficacy as judged by the investigator.
Figure 6.
Kaplan-Meier Estimates of Proportion of Patients with Recurrence (Study 9) In a U.S.-based maintenance study (Study 10 in Figure 7 ), 1106 patients meeting DSM-IV-TR criteria for MDD were treated with a fixed dose of TRINTELLIX 10 mg once daily during an initial 16 week open-label treatment phase.
Five hundred and eighty (580) patients who were in remission (MADRS total score ≤12 at both Weeks 14 and 16) after open-label treatment were randomized in a 1:1:1:1 ratio to TRINTELLIX 5 mg/day, 10 mg/day, 20 mg/day, or placebo daily for 32 weeks.
The definition of recurrence of depressive episodes was the same as for Study 9.
For all three doses of TRINTELLIX evaluated, patients treated with TRINTELLIX experienced a statistically significantly longer time to recurrence of depressive episodes than did patients treated with placebo.
Figure 7.
Kaplan-Meier Estimates of Proportion of Patients with Recurrence (Study 10) Figure 6 Figure 7 Prospective Evaluation of Treatment Emergent Sexual Dysfunction (TESD) Two, randomized, double-blind, active-controlled studies were conducted to prospectively compare the incidence of TESD between TRINTELLIX and SSRIs via a validated self-rated measure of sexual function, the Changes in Sexual Functioning Questionnaire Short Form (CSFQ-14).
The CSFQ-14 is designed to measure illness- and medication-related changes in sexual functioning that consists of 14 items measuring sexual functioning as a total score.
The CSFQ-14 consists of subscales that assess the three phases of the sexual response cycle (desire, arousal, and orgasm).
Higher scores on the CSFQ-14 indicate greater sexual function and for reference, a 2-3 point change is considered clinically meaningful.
Effect of Switching from SSRI to TRINTELLIX on TESD The effect of TRINTELLIX on TESD induced by prior SSRI treatment in MDD patients whose depressive symptoms were adequately treated was evaluated in an eight-week, randomized, double-blind, active-controlled (escitalopram), flexible-dose study (Study 11).
Patients taking citalopram, sertraline, or paroxetine for at least eight weeks duration and who were experiencing sexual dysfunction attributed to their SSRI treatment were switched to TRINTELLIX (n=217) or escitalopram (n=207).
For both TRINTELLIX and escitalopram, patients were started on 10 mg, increased to 20 mg at Week 1, followed by flexible dosing.
The majority of subjects received the 20 mg dose of TRINTELLIX (65.6%) or the 20 mg dose of escitalopram (71.9%) during the study.
Improvement in TESD induced by prior SSRI treatment in subjects switched to TRINTELLIX was superior to the improvement observed in those subjects who switched to escitalopram (2.2 point improvement vs escitalopram on the change from Baseline in CSFQ-14 total score, with 95% confidence interval 0.48 – 4.02), after eight weeks of treatment, while both drugs maintained the subjects’ prior antidepressant response.
For change from Baseline in CSFQ-14, see Figure 8 .

GERIATRIC USE
8.5 Geriatric Use No dose adjustment is recommended on the basis of age (Figure 1) .
Results from a single-dose pharmacokinetic study in elderly (>65 years old) vs young (24 to 45 years old) subjects demonstrated that the pharmacokinetics were generally similar between the two age groups.
Of the 2616 subjects in clinical studies of TRINTELLIX, 11% (286) were 65 and over, which included subjects from a placebo-controlled study specifically in elderly patients [see Clinical Studies (14) ] .
No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients.
Serotonergic antidepressants have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse event [see Warnings and Precautions (5.7) ] .
DOSAGE FORMS AND STRENGTHS
3 TRINTELLIX is available as immediate-release, film-coated tablets in the following strengths: 5 mg: pink, almond shaped biconvex film coated tablet, debossed with “5” on one side and “TL” on the other side 10 mg: yellow, almond shaped biconvex film coated tablet, debossed with “10” on one side and “TL” on the other side 20 mg: red, almond shaped biconvex film coated tablet, debossed with “20” on one side and “TL” on the other side Tablets: 5 mg, 10 mg and 20 mg ( 3 ).
MECHANISM OF ACTION
12.1 Mechanism of Action The mechanism of the antidepressant effect of vortioxetine is not fully understood, but is thought to be related to its enhancement of serotonergic activity in the CNS through inhibition of the reuptake of serotonin (5-HT).
It also has several other activities including 5-HT3 receptor antagonism and 5-HT1A receptor agonism.
The contribution of these activities to vortioxetine’s antidepressant effect has not been established.
INDICATIONS AND USAGE
1 TRINTELLIX is indicated for the treatment of major depressive disorder (MDD) in adults.
TRINTELLIX is indicated for the treatment of major depressive disorder (MDD) in adults ( 1 , 14 ).
PEDIATRIC USE
8.4 Pediatric Use The safety and effectiveness of TRINTELLIX have not been established in pediatric patients for the treatment of MDD.
Efficacy was not established in an 8-week, randomized, double-blind, placebo-controlled, active-reference study in 615 pediatric patients 12 to 17 years of age with MDD.
The primary efficacy endpoint was change from double-blind baseline to Week 8 on the Children’s Depression Rating Scale-Revised version.
The effect of treatment with vortioxetine was not significantly different from placebo (placebo-subtracted difference of 0.21 (95% CI: -2.41, 2.82; p=0.88).
In this age group, adverse reactions to TRINTELLIX were generally similar to those reported in adults.
Antidepressants, such as TRINTELLIX, increase the risk of suicidal thoughts and behaviors in pediatric patients [see the Boxed Warning and Warnings and Precautions (5.1) ] .
Juvenile Animal Toxicity Data Administration of vortioxetine to juvenile rats (oral doses of 10, 20, and 40 mg/kg/day twice daily from Postnatal Day 21 to 91) resulted in a neurobehavioral effect at the highest dose of 40 mg/kg twice daily (increased peak auditory startle amplitude) during the treatment period.
The effect was not seen at the end of the recovery period.
When animals were mated after the 4-week recovery period, viability was decreased in the offspring of mated pairs treated with 40 mg/kg twice daily.
The no-observed adverse effect dose was 20 mg/kg twice daily based on both the neurobehavioral and reproductive effects.
This dose was associated with plasma vortioxetine exposure (AUC) approximately 2 times that in pediatric patients.
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 There are limited human data on TRINTELLIX use during pregnancy to inform any drug-associated risks.
However, there are clinical considerations regarding neonates exposed to SSRIs and SNRIs, including TRINTELLIX, during the third trimester of pregnancy [see Clinical Considerations ] .
Vortioxetine administered to pregnant rats and rabbits during the period of organogenesis at doses ≥15 times and 10 times the maximum recommended human dose (MRHD), respectively, resulted in decreased fetal body weight and delayed ossification.
No malformations were seen at doses up to 77 times and 58 times the MRHD, respectively.
Vortioxetine administered to pregnant rats during gestation and lactation at oral doses ≥20 times the MRHD resulted in a decrease in the number of live-born pups and an increase in early postnatal pup mortality.
Decreased pup weight at birth to weaning occurred at 58 times the MRHD and delayed physical development occurred at ≥20 times the MRHD.
These effects were not seen at 5 times the MRHD [see Data ] .
Advise a pregnant woman of the potential risk to a fetus.
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 2-4% and 15-20%, respectively.
Clinical Considerations Disease-associated maternal and/or embryo/fetal risk A prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy.
The women who discontinued antidepressants during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressants.
Consider the risks of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum.
Fetal/Neonatal adverse reactions Exposure to serotonergic antidepressants, including TRINTELLIX, in late pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, and tube feeding, and/or persistent pulmonary hypertension of the newborn (PPHN).
Monitor neonates who were exposed to TRINTELLIX in the third trimester of pregnancy for PPHN and drug discontinuation syndrome [see Data ] .
Data Human Data Third Trimester Exposure Neonates exposed to SSRIs or SNRIs, late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support and tube feeding.
These findings are based on postmarketing reports.
Such complications can arise immediately upon delivery.
Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability and constant crying.
These features are consistent with either a direct toxic effect of SSRIs and SNRIs or possibly, a drug discontinuation syndrome.
In some cases, the clinical picture was consistent with serotonin syndrome [see Warnings and Precautions (5.2) ] .
Exposure during late pregnancy to SSRIs may have an increased risk for persistent pulmonary hypertension of the newborn (PPHN).
PPHN occurs in one to two per 1,000 live births in the general population and is associated with substantial neonatal morbidity and mortality.
In a retrospective case-control study of 377 women whose infants were born with PPHN and 836 women whose infants were born healthy, the risk for developing PPHN was approximately six fold higher for infants exposed to SSRIs after the 20th week of gestation compared to infants who had not been exposed to antidepressants during pregnancy.
A study of 831,324 infants born in Sweden in 1997 – 2005 found a PPHN risk ratio of 2.4 (95% CI 1.2-4.3) associated with patient-reported maternal use of SSRIs “in early pregnancy” and a PPHN risk ratio of 3.6 (95% CI 1.2-8.3) associated with a combination of patient-reported maternal use of SSRIs “in early pregnancy” and an antenatal SSRI prescription “in later pregnancy.” Animal Data In pregnant rats and rabbits, no malformations were seen when vortioxetine was given during the period of organogenesis at oral doses up to 160 and 60 mg/kg/day, respectively.
These doses are 77 and 58 times the maximum recommended human dose (MRHD) of 20 mg on a mg/m 2 basis, in rats and rabbits, respectively.
Developmental delay, seen as decreased fetal body weight and delayed ossification, occurred in rats and rabbits at doses equal to and greater than 30 and 10 mg/kg (15 and 10 times the MRHD, respectively) in the presence of maternal toxicity (decreased food consumption and decreased body weight gain).
When vortioxetine was administered to pregnant rats at oral doses of 40 and 120 mg/kg (20 and 58 times the MRHD, respectively) throughout pregnancy and lactation, the number of live-born pups was decreased and early postnatal pup mortality was increased.
Additionally, pup weights were decreased at birth to weaning at 120 mg/kg and development (specifically eye opening) was slightly delayed at 40 and 120 mg/kg.
These effects were not seen at 10 mg/kg (5 times the MRHD).
BOXED WARNING
WARNING: SUICIDAL THOUGHTS AND BEHAVIORS Antidepressants increased the risk of suicidal thoughts and behavior in pediatric and young adult patients in short-term studies.
Closely monitor all antidepressant-treated patients for clinical worsening, and for emergence of suicidal thoughts and behaviors [see Warnings and Precautions (5.1) ] .
TRINTELLIX is not approved for use in pediatric patients [see Use in Specific Populations (8.4) ] .
WARNING: SUICIDAL THOUGHTS AND BEHAVIORS See full prescribing information for complete boxed warning.
Increased risk of suicidal thinking and behavior in pediatric and young adult patients taking antidepressants.
Closely monitor for worsening and emergence of suicidal thoughts and behaviors ( 5.1 ).
TRINTELLIX is not approved for use in pediatric patients ( 8.4 ).
WARNING AND CAUTIONS
5 WARNINGS AND PRECAUTIONS Serotonin Syndrome : Increased risk when co-administered with other serotonergic agents (SSRIs, SNRIs, and triptans), but also when taken alone.
If it occurs, discontinue TRINTELLIX and initiate supportive measures ( 5.2 ).
Increased Risk of Bleeding : Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs, other antiplatelet drugs, warfarin, or other drugs that affect coagulation may increase risk ( 5.3 ).
Activation of Mania/Hypomania : Screen patients for bipolar disorder ( 5.4 ).
Angle Closure Glaucoma: Angle closure glaucoma has occurred in patients with untreated anatomically narrow angles treated with antidepressants ( 5.6 ).
Hyponatremia : Can occur in association with the syndrome of inappropriate antidiuretic hormone secretion (SIADH) ( 5.7 ).
Sexual Dysfunction: TRINTELLIX may cause symptoms of sexual dysfunction ( 5.8 ).
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 of Suicidal Thoughts and Behaviors 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 and 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 TRINTELLIX is not approved for use in pediatric patients.
It is unknown whether the risk of suicidal thoughts and behaviors in 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 the use of antidepressants can delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors.
Monitor all antidepressant-treated patients for all approved populations for 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 TRINTELLIX, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts and behaviors.
5.2 Serotonin Syndrome The development of a potentially life-threatening serotonin syndrome has been reported with serotonergic antidepressants including TRINTELLIX, when used alone but more often when used concomitantly with other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and 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 and intravenous methylene blue).
Serotonin syndrome 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/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
Patients should be monitored for the emergence of serotonin syndrome.
The concomitant use of TRINTELLIX with MAOIs intended to treat psychiatric disorders is contraindicated.
TRINTELLIX should also not be started in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue.
All reports with methylene blue that provided information on the route of administration involved intravenous administration in the dose range of 1 mg/kg to 8 mg/kg.
No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection) or at lower doses.
There may be circumstances when it is necessary to initiate treatment with a MAOI such as linezolid or intravenous methylene blue in a patient taking TRINTELLIX.
TRINTELLIX should be discontinued before initiating treatment with the MAOI [see Contraindications (4) , Drug Interactions (7.1) ] .
If concomitant use of TRINTELLIX with other serotonergic drugs, including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, buspirone, tryptophan, and St.
John’s Wort is clinically warranted, patients should be made aware of a potential increased risk for serotonin syndrome, particularly during treatment initiation and dose increases.
Treatment with TRINTELLIX and any concomitant serotonergic agents should be discontinued immediately if the above events occur and supportive symptomatic treatment should be initiated.
5.3 Increased Risk of Bleeding The use of drugs that interfere with serotonin reuptake inhibition, including TRINTELLIX, may increase the risk of bleeding events.
Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), warfarin, and other anticoagulants may add to this risk.
Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding.
Bleeding events related to drugs that inhibit serotonin reuptake have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages.
Inform patients about the increased risk of bleeding when TRINTELLIX is coadministered with NSAIDs, aspirin, or other drugs that affect coagulation or bleeding.
For patients taking warfarin, carefully monitor coagulation indices when initiating, titrating, or discontinuing TRINTELLIX [see Drug Interactions (7.1) ] .
5.4 Activation of Mania/Hypomania In patients with bipolar disorder, treating a depressive episode with TRINTELLIX or another antidepressant may precipitate a mixed/manic episode.
Symptoms of mania/hypomania were reported in <0.1% of patients treated with TRINTELLIX in premarketing clinical studies.
Prior to initiating treatment with TRINTELLIX, screen patients for any personal or family history of bipolar disorder, mania, or hypomania.
5.5.
Discontinuation Syndrome Adverse reactions have been reported upon abrupt discontinuation of treatment with TRINTELLIX at doses of 15 mg/day and 20 mg/day [see Adverse Reactions (6.1) ] .
A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible [see Dosage and Administration (2.3) ].
Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures.
5.6 Angle Closure Glaucoma The pupillary dilation that occurs following use of many antidepressant drugs, including TRINTELLIX, may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy.
5.7 Hyponatremia Hyponatremia has occurred as a result of treatment with serotonergic drugs, including TRINTELLIX.
In many cases, hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH).
One case with serum sodium lower than 110 mmol/L was reported in a subject treated with TRINTELLIX in a premarketing clinical study.
Elderly patients may be at greater risk of developing hyponatremia with a serotonergic antidepressant.
Also, patients taking diuretics or who are otherwise volume-depleted can be at greater risk.
Discontinuation of TRINTELLIX in patients with symptomatic hyponatremia and appropriate medical intervention should be instituted.
Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which can lead to falls.
More severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death.
5.8 Sexual Dysfunction Use of serotonergic antidepressants, including TRINTELLIX, may cause symptoms of sexual dysfunction [see Adverse Reactions (6.1) ] .
In male patients, serotonergic antidepressant use may result in ejaculatory delay or failure, decreased libido, and erectile dysfunction.
In female patients, use may result in decreased libido and delayed or absent orgasm.
It is important for prescribers to inquire about sexual function prior to initiation of TRINTELLIX and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported.
When evaluating changes in sexual function, obtaining a detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including the underlying psychiatric disorder.
Discuss potential management strategies to support patients in making informed decisions about treatment.
INFORMATION FOR PATIENTS
17 PATIENT COUNSELING INFORMATION See FDA-approved patient labeling (Medication Guide) .
Suicidal Thoughts and Behaviors Advise patients and caregivers to look for the emergence of suicidal ideation and behavior, especially early during treatment and when the dose is adjusted up or down, and instruct them to report such symptoms to the healthcare provider [see Boxed Warning , Warnings and Precautions (5.1) ] .
Concomitant Medication Advise patients to inform their healthcare provider if they are taking, or plan to take, any prescription or over-the-counter medications because of a potential for interactions.
Instruct patients not to take TRINTELLIX with an MAOI or within 14 days of stopping an MAOI and to allow 21 days after stopping TRINTELLIX before starting an MAOI [see Dosage and Administration (2.4) , Contraindications (4) , Warnings and Precautions (5.2) , Drug Interactions (7.1) ] .
Serotonin Syndrome Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of TRINTELLIX and triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan supplements, busipirone, and 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) [see Warnings and Precautions (5.2) , Drug Interactions (7.1 , 7.2) ] .
Instruct patients to contact their health care provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome.
Increased Risk of Bleeding Inform patients about the concomitant use of TRINTELLIX with NSAIDs, aspirin, warfarin, or other drugs that affect coagulation because combined use has been associated with an increased risk of bleeding.
Advise patients to inform their health care provider if they are taking or planning to take any prescription or over-the-counter medications that increase the risk of bleeding [see Warnings and Precautions (5.3) ] .
Activation of Mania/Hypomania Advise patients and their caregivers to look for signs of activation of mania/hypomania [see Warnings and Precautions (5.4) ] .
Discontinuation of Treatment Advise patients not to abruptly stop taking TRINTELLIX without first talking to their healthcare provider.
Patients should be aware that discontinuation effects may occur when stopping TRINTELLIX and they should monitor for discontinuation symptoms [see Warnings and Precautions (5.5) and Adverse Reactions (6.1) ].
Angle Closure Glaucoma Patients should be advised that taking TRINTELLIX 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 (5.6) ] .
Hyponatremia Advise patients that if they are treated with diuretics, or are otherwise volume depleted, or are elderly, they may be at greater risk of developing hyponatremia while taking TRINTELLIX [see Warnings and Precautions (5.7) ] .
Sexual Dysfunction Advise patients that use of TRINTELLIX may cause symptoms of sexual dysfunction in both male and female patients.
Inform patients that they should discuss any changes in sexual function and potential management strategies with their healthcare provider [see Warnings and Precautions (5.8) ].
Nausea Advise patients that nausea is one of the most common adverse reactions, and is dose related.
Nausea commonly occurs within the first week of treatment, then decreases in frequency but can persist in some patients [see Adverse Reactions (6.1) ] .
Allergic Reactions Advise patients to notify their healthcare provider if they develop an allergic reaction such as rash, hives, swelling, or difficulty breathing.
Pregnancy Advise a pregnant woman or a woman planning to become pregnant that TRINTELLIX may cause withdrawal symptoms in the newborn or persistent pulmonary hypertension of the newborn (PPHN) [see Use in Specific Populations (8.1) ] .
Advise the patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to TRINTELLIX during pregnancy [see Use in Specific Populations (8.1) ] .
DOSAGE AND ADMINISTRATION
2 The recommended starting dose is 10 mg administered orally once daily without regard to meals ( 2.1 ).
The dose should then be increased to 20 mg/day, as tolerated ( 2.1 ).
Consider 5 mg/day for patients who do not tolerate higher doses ( 2.1 ).
TRINTELLIX can be discontinued abruptly.
However, it is recommended that doses of 15 mg/day or 20 mg/day be reduced to 10 mg/day for one week prior to full discontinuation if possible ( 2.3 ).
The maximum recommended dose is 10 mg/day in known CYP2D6 poor metabolizers ( 2.5 ).
2.1 Recommended Dosage The recommended starting dose is 10 mg administered orally once daily without regard to meals.
Dosage should then be increased to 20 mg/day, as tolerated.
The efficacy and safety of doses above 20 mg/day have not been evaluated in controlled clinical trials.
A dose decrease down to 5 mg/day may be considered for patients who do not tolerate higher doses [see Clinical Studies (14) ] .
2.2 Screen for Bipolar Disorder Prior to Starting TRINTELLIX Prior to initiating treatment with TRINTELLIX or another antidepressant, screen patients for personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.4) ] .
2.3 Discontinuing Treatment Although TRINTELLIX can be abruptly discontinued, in placebo-controlled trials patients experienced transient adverse reactions such as headache and muscle tension following abrupt discontinuation of TRINTELLIX 15 mg/day or 20 mg/day.
It is recommended that the dose be decreased to 10 mg/day for one week before full discontinuation of TRINTELLIX 15 mg/day or 20 mg/day [see Warnings and Precautions (5.5) and Adverse Reactions (6) ] .
2.4 Switching a Patient to or From a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders At least 14 days must elapse between discontinuation of a MAOI intended to treat psychiatric disorders and initiation of therapy with TRINTELLIX to avoid the risk of Serotonin Syndrome [see Warnings and Precautions (5.2) ] .
Conversely, at least 21 days must elapse after stopping TRINTELLIX before starting an MAOI intended to treat psychiatric disorders [see Contraindications (4) ] .
2.5 Use of TRINTELLIX in Known CYP2D6 Poor Metabolizers or in Patients Taking Strong CYP2D6 Inhibitors The maximum recommended dose of TRINTELLIX is 10 mg/day in known CYP2D6 poor metabolizers.
Reduce the dose of TRINTELLIX by one-half when patients are receiving a CYP2D6 strong inhibitor (e.g., bupropion, fluoxetine, paroxetine, or quinidine) concomitantly.
The dose should be increased to the original level when the CYP2D6 inhibitor is discontinued [see Drug Interactions (7.1) , Use in Specific Populations (8.6) ] .
2.6 Use of TRINTELLIX in Patients Taking Strong CYP Inducers Consider increasing the dose of TRINTELLIX when a strong CYP inducer (e.g., rifampin, carbamazepine, or phenytoin) is coadministered for greater than 14 days.
The maximum recommended dose should not exceed three times the original dose.
The dose of TRINTELLIX should be reduced to the original level within 14 days, when the inducer is discontinued [see Drug Interactions (7.1) ] .
