Tranylcypromine Sulfate

1 INDICATIONS & USAGE Tranylcypromine sulfate tablets are indicated for the treatment of major depressive disorder (MDD) in adult patients who have not responded adequately to other antidepressants. Tranylcypromine sulfate tablets are not indicated for the initial treatment of MDD due to the potential for serious adverse reactions and drug interactions, and the need for dietary restrictions [see Contraindications (4), Warnings and Precautions (5) , and Drug Interactions (7)]. Tranylcypromine sulfate tablets are a monoamine oxidase inhibitor (MAOI) indicated for the treatment of major depressive disorder (MDD) in adult patients who have not responded adequately to other antidepressants ( 1 ) Tranylcypromine sulfate tablets are not indicated for the initial treatment of MDD due to the potential for serious adverse reactions and drug interactions, and the need for dietary restrictions ( 1 , 4 , 5 , 7 )

2 DOSAGE & ADMINISTRATION Recommended daily dosage is 30 mg in divided doses (2.1) If no adequate response, increase dosage in increments of 10 mg per day every 1 to 3 weeks to a maximum dosage of 30 mg twice daily (60 mg per day).Consider more gradual dosage increases in patients at risk for hypotension (2.1) Consider discontinuing tranylcypromine sulfate tablets therapy gradually because of the risk for withdrawal effects ( 2.3 , 5.8 , 9.3 ) Switching from or to other MAOIs or other antidepressants: See full prescribing information for instructions ( 2.2 , 7.1 ) 2.1 Recommended Dosage Tranylcypromine sulfate tablets are for oral use. The recommended dosage is 30 mg per day (in divided doses). If patients do not have an adequate response, increase the dosage in increments of 10 mg per day every 1 to 3 weeks to a maximum 30 mg twice daily (60 mg per day). Dosage increases should be made more gradually in patients at risk for hypotension (e.g., geriatric patients) [see Warnings and Precautions (5.5)]. 2.2 Switching to or from Other Antidepressants Switching from Contraindicated Antidepressants to Tranylcypromine Sulfate Tablets After stopping treatment with contraindicated antidepressants, a time period of 4 to 5 half-lives of the other antidepressant or any active metabolite should elapse before starting treatment with tranylcypromine sulfate tablets. After stopping treatment with an MAO inhibitor antidepressant, a time period of at least one week or 4 to 5 half-lives of the other MAO inhibitor (whichever is longer) should elapse before starting treatment with tranylcypromine sulfate tablets to reduce the risk of additive effects [see Contraindications (4.1) and Drug Interactions (7.1)]. Switching from Tranylcypromine Sulfate Tablets to Other MAOIs or Contraindicated Antidepressants After stopping tranylcypromine sulfate tablets treatment, at least one week should elapse before starting another MAOI (intended to treat MDD) or other contraindicated antidepressants.Refer to the prescribing information of the subsequently used drug for product-specific advice on a medication-free interval [ see Contraindications (4.1) and Drug Interactions (7.1)]. 2.3 Discontinuing Treatment Withdrawal effects, including delirium, have been reported with abrupt discontinuation of tranylcypromine sulfate tablets therapy. Higher daily doses and longer duration of use appear to be associated with a higher risk of withdrawal effects. Consider discontinuing tranylcypromine sulfate tablets therapy by slow, gradual dosage reduction [see Warnings and Precautions (5.8) and Drug Abuse and Dependence (9.3)]. 2.4 Screen for Bipolar Disorder and Elevated Blood Pressure Prior to Starting Tranylcypromine Sulfate Tablets Prior to initiating treatment with tranylcypromine sulfate tablets: Screen patients for a history of mania [see Warnings and Precautions(5.4)]. Measure blood pressure [see Warnings and Precautions (5.2, 5.5)].

5 WARNINGS AND PRECAUTIONS Activation of Mania/Hypomania: May be precipitated by antidepressant treatment in patients with bipolar disorder. Screen patients prior to treatment (5.4) Hypotension (including syncope): Monitor patients and adjust tranylcypromine sulfate tablets dosage or concomitant medication as necessary (5.5) Hypotension and Hypertension during Anesthesia and Perioperative Care: If possible, discontinue tranylcypromine sulfate tablets prior to elective surgery (5.6) Hepatitis and Elevated Liver Enzymes: Monitor accordingly (5.10) 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 2. Table 2: Risk Differences of the Number of Patients of 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 of 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 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 tranylcypromine sulfate tablets , in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors. 5.2 Hypertensive Crisis and Hypertension Hypertensive Crisis MAOIs, including tranylcypromine sulfate tablets, have been associated with hypertensive crises caused by the ingestion of foods or beverages with a high concentration of tyramine. In addition, hypertensive reactions and crises may occur with concomitant use of other drugs [see Drug Interactions (7.1)] . Patients with hyperthyroidism may be at greater risk of hypertensive crisis. Signs, Symptoms, and Complications of Hypertensive Crisis: In some patients a hypertensive crisis constitutes a hypertensive emergency, which requires immediate attention to prevent serious complications or fatal outcome. These emergencies are characterized by severe hypertension (e.g., with a blood pressure of more than 180/120 mm Hg) and evidence of organ dysfunction. Symptoms may include occipital headache (which may radiate frontally), palpitations, neck stiffness or soreness, nausea or vomiting, sweating (sometimes with fever or cold, clammy skin), dilated pupils, photophobia, shortness of breath, or confusion. Either tachycardia or brady…

4 CONTRAINDICATIONS Concomitant use or use in rapid succession with other MAOIs; selective serotonin reuptake inhibitors; serotonin and norepinephrine reuptake inhibitors; tricyclic antidepressants; sympathomimetic drugs; and numerous other drugs. See Full Prescribing Information for the full list of contraindicated products ( 4.1 , 7.1 ) Pheochromocytoma, other catecholamine-releasing paraganglioma ( 4.2 ) 4.1 Combination with Certain Drugs Concomitant use of tranylcypromine sulfate tablets or use in rapid succession with the products in Table 1 is contraindicated. Such use may cause severe or life-threatening reactions such as hypertensive crises or serotonin syndrome [see Drug Interactions (7.1)]. Medication-free periods between administration of tranylcypromine sulfate tablets and contraindicated agents are recommended [ see Dosage and Administration (2.2) and Drug Interactions (7.1) ]. Table 1: Products Contraindicated with the Use of Tranylcypromine Sulfate Tablets Drug Classes Non-selective H1 receptor antagonists Antidepressants including but not limited to: Other monoamine oxidase inhibitors (MAOIs) Selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) Tricyclic antidepressants Other antidepressants (e.g., amoxapine, bupropion, maprotiline, nefazodone, trazodone, vilazodone, vortioxetine) Amphetamines and methylphenidates and derivatives Sympathomimetic products (e.g., cold, hay fever or weight reducing products that contain vasoconstrictors such as pseudoephedrine, phenylephrine, and ephedrine; or dietary supplements that contain sympathomimetics) Triptans Individual Drugs (not included in the above classes) buspirone levodopa s-adenosyl-L-methionine (SAM-e) carbamazepine meperidine tapentadol cyclobenzaprine methyldopa tetrabenazine dextromethorphan milnacipran tryptophan dopamine rasagiline hydroxytryptophan reserpine 4.2 Pheochromocytoma and Catecholamine-Releasing Paragangliomas Tranylcypromine sulfate tablets are contraindicated in the presence of pheochromocytoma or other catecholamine-releasing paragangliomas because such tumors secrete pressor substances and can lead to hypertensive crisis [see Warnings and Precautions (5.3)].

7 DRUG INTERACTIONS See Full Prescribing Information for a list of products, foods and beverages that can interact with tranylcypromine sulfate tablets (7) 7.1 Clinically Significant Drug Interactions Tables 3 and 4 lists drug classes and individual products, respectively, with a potential for interaction with tranylcypromine sulfate tablets, describes the predominant observed or anticipated risks, and provides advice on concomitant use. Given serious adverse reactions with multiple agents, patients should avoid taking over-the-counter medications or dietary supplements without prior consultation with a healthcare provider able to provide advice on the potential for interactions. Time to Start Tranylcypromine Sulfate Tablets after Discontinuation of a Contraindicated Drug For products that are contraindicated with tranylcypromine sulfate tablets, a time period of 4 to 5 half-lives of the other product or any active metabolite should elapse before starting treatment with tranylcypromine sulfate tablets. After stopping treatment with an MAO inhibitor antidepressant, a time period of at least 1 week or 4 to 5 half-lives of the other MAO inhibitor (whichever is longer) should elapse before starting treatment with tranylcypromine sulfate tablets because of the risk for clinically significant adverse reactions after discontinuation due to persistent MAO inhibition [see Dosage and Administration (2.2) , Warnings and Precautions (5.9) ] . This period can be several weeks long (e.g., a minimum of 5 weeks for fluoxetine given fluoxetine's long half-life). Refer to the prescribing information of the contraindicated product for relevant information. Time to Start Contraindicated Drug after Discontinuation of Tranylcypromine Sulfate Tablets The potential for interactions persists after discontinuation of tranylcypromine sulfate tablets until MAO activity has sufficiently recovered. Inhibition of MAO may persist up to 10 days following discontinuation [see Warnings and Precautions (5.9)] . After stopping tranylcypromine sulfate tablets, at least 1 week should elapse before starting another MAOI (intended to treat MDD) or other contraindicated antidepressants. Refer to the prescribing information of any agent considered for subsequent use for recommendations on the duration of a waiting period after discontinuation of a MAO inhibitor. If in the absence of therapeutic alternatives and emergency treatment with a contraindicated drug (e.g., linezolid, intravenous methylene blue, direct-acting sympathomimetic drugs such as epinephrine) becomes necessary and cannot be delayed, discontinue tranylcypromine sulfate tablets as soon as possible before initiating treatment with the other agent, and monitor closely for adverse reactions.

8.1 Pregnancy Risk Summary There are limited published reports of placental infarction and congenital anomalies in association with use of tranylcypromine sulfate tablets during pregnancy; however, these reports may not adequately inform the presence or absence of drug-associated risk with the use of tranylcypromine sulfate tablets during pregnancy. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Animal embryo-fetal development studies were not conducted with tranylcypromine; however, published animal reproduction studies report placental transfer of tranylcypromine in rats and a dose-dependent decrease in uterine blood flow in pregnant sheep. Advise pregnant women of the potential risk to a fetus. Clinical Considerations Labor or Delivery During labor and delivery, the potential for interactions between tranylcypromine sulfate tablets and drugs or procedures (e.g., epidural anesthesia) should be taken into account in women who have received tranylcypromine sulfate tablets [see Warnings and Precautions (5.6) and Drug Interactions (7.1)].
