Warnings
Contraindications
4 CONTRAINDICATIONS Hypersensitivity to vortioxetine or any component of the formulation. Hypersensitivity reactions including anaphylaxis, angioedema, and urticaria have been reported in patients treated with TRINTELLIX [see Adverse Reactions (6.2) ] . The use of MAOIs intended to treat psychiatric disorders with TRINTELLIX or within 21 days of stopping treatment with TRINTELLIX is contraindicated because of an increased risk of serotonin syndrome. The use of TRINTELLIX within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated [see Dosage and Administration (2.4) , Warnings and Precautions (5.2) ] . Starting TRINTELLIX in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome [see Warnings and Precautions (5.2) ] . Hypersensitivity to vortioxetine or any components of the TRINTELLIX formulation ( 4 ). Monoamine Oxidase Inhibitors (MAOIs): Do not use MAOIs intended to treat psychiatric disorders with TRINTELLIX or within 21 days of stopping treatment with TRINTELLIX. Do not use TRINTELLIX within 14 days of stopping an MAOI intended to treat psychiatric disorders. In addition, do not start TRINTELLIX in a patient who is being treated with linezolid or intravenous methylene blue ( 4 ).
Overdose
10 OVERDOSAGE 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. No specific antidotes for TRINTELLIX are known. Consider contacting the Poison Help Line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
Drug interactions
7 DRUG INTERACTIONS Strong inhibitors of CYP2D6: Reduce TRINTELLIX dose by half when coadministered ( 2.5 , 7.1 ). Strong CYP Inducers: Consider dose increase of TRINTELLIX dose when coadministered for more than 14 days. The maximum recommended dose should not exceed 3 times the original dose ( 2.6 , 7.1 ). 7.1 Drugs Having Clinically Important Interactions with TRINTELLIX Table 4: Clinically Important Drug Interactions with TRINTELLIX Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact The concomitant use of SSRIs and SNRIs including TRINTELLIX with MAOIs increases the risk of serotonin syndrome. Intervention Concomitant use of TRINTELLIX is contraindicated: With an MAOI intended to treat psychiatric disorders or within 21 days of stopping treatment with TRINTELLIX. Within 14 days of stopping an MAOI intended to treat psychiatric disorders. In a patient who is being treated with linezolid or intravenous methylene blue. [see Dosage and Administration (2.4) , Contraindications (4) , Warnings and Precautions (5.2) ] Examples selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue Other Serotonergic Drugs Clinical Impact Concomitant use of TRINTELLIX with other serotonergic drugs increases the risk of serotonin syndrome. Intervention Monitor for symptoms of serotonin syndrome when TRINTELLIX is used concomitantly with other drugs that may affect the serotonergic neurotransmitter systems. If serotonin syndrome occurs, consider discontinuation of TRINTELLIX and/or concomitant serotonergic drugs [see Warnings and Precautions (5.2) ] . Examples Other SNRIs, SSRIs, triptans, tricyclic antidepressants, opioids, lithium, buspirone, amphetamines, tryptophan, and St. John's Wort Strong Inhibitors of CYP2D6 Clinical Impact Concomitant use of TRINTELLIX with strong CYP2D6 inhibitors increases plasma concentrations of vortioxetine. Intervention Reduce TRINTELLIX dose by half when a strong CYP2D6 inhibitor is coadministered [see Dosage and Administration (2.5) ] . Examples bupropion, fluoxetine, paroxetine, quinidine Strong CYP Inducers Clinical Impact Concomitant use of TRINTELLIX with a strong CYP inducer decreases plasma concentrations of vortioxetine. Intervention Consider increasing the TRINTELLIX dose when a strong CYP inducer is coadministered. The maximum dose is not recommended to exceed three times the original dose [see Dosage and Administration (2.6) ]. Examples rifampin, carbamazepine, phenytoin Drugs that Interfere with Hemostasis (antiplatelets agents and anticoagulants) Clinical Impact Concomitant use of TRINTELLIX with an antiplatelet or anticoagulant drug may potentiate the risk of bleeding. Intervention Inform patients of the increased risk of bleeding associated with the concomitant use of TRINTELLIX and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio [see Warnings and Precautions (5.3) , Drug Interactions (7.2) ] . Examples aspirin, clopidogrel, heparin, warfarin Drugs Highly Bound to Plasma Protein Clinical Impact TRINTELLIX is highly bound to plasma protein. The concomitant use of TRINTELLIX with another drug that is highly bound to plasma protein may increase free concentrations of TRINTELLIX or other tightly-bound drugs in plasma . Intervention Monitor for adverse reactions and reduce dosage of TRINTELLIX or other protein bound drugs as warranted [see Drug Interactions (7.2) ] . Examples Warfarin 7.2 Effect of TRINTELLIX on Other Drugs Other CNS Active Agents No clinically relevant effect was observed on steady-state lithium exposure following coadministration with multiple daily doses of TRINTELLIX. Multiple doses of TRINTELLIX did not affect the pharmacokinetics or pharmacodynamics (composite cognitive score) of diazepam [see Clinical Pharmacology (12.3) ] . A clinical study has shown that TRINTELLIX (single dose of 20 or 40 mg) did not increase the impairment of mental and motor skills caused by alcohol (single dose of 0.6 g/kg) [see Clinical Pharmacology (12.3) ] . 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.

Dosage forms & strengths
2 DOSAGE AND ADMINISTRATION 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) ] .
