Tranylcypromine tablets are indicated for the treatment of major depressive disorder (MDD) in adult patients who have not responded adequately to other antidepressants. Tranylcypromine 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 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 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)
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)
4.1Combination with Certain Drugs
Concomitant use of tranylcypromine 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 tablets and contraindicated agents are recommended [see Dosage and Administration (2.2) and Drug Interactions (7.1)].

4.2Pheochromocytoma and Catecholamine-Releasing Paragangliomas
Tranylcypromine 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)].
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 tablets dosage or concomitant medication as necessary (5.5) Hypotension and Hypertension during Anesthesia and Perioperative Care : If possible, discontinue tranylcypromine tablets prior to elective surgery (5.6) Hepatitis and Elevated Liver Enzymes : Monitor accordingly (5.10)
5.1Suicidal 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 tablets, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.
5.2Hypertensive Crisis and Hypertension
H y p er tensive Crisis MAOIs, including tranylcypromine 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 bradycardia may be present and may be associated with constricting chest pain.
Seizures may also occur. Intracranial bleeding, sometimes fatal, has been reported in association with the increase in blood pressure. Strategies to Reduce the Risk of Hypertensive Crisis: Instruct patients to avoid foods and beverages with high tyramine content while being treated with tranylcypromine tablets and for 2 weeks after stopping tranylcypromine tablets [see Drug Interactions (7.2)] . Careful evaluation of the benefits and risks of tranylcypromine tablets therapy is necessary in patients with: Hypertension or confirmed or suspected cerebrovascular or cardiovascular disorders that constitute an increased risk for complications from severe hypertension, and A history of headaches that can mask the occurrence of headaches as prodromal of a hypertensive crisis.
In all patients taking tranylcypromine tablets, monitor blood pressure closely to detect evidence of increased blood pressure. Full reliance should not be placed on blood pressure readings. The patient should also be observed for other signs and symptoms of hypertensive crisis. Treatment of Hypertensive Crisis: Therapy should be interrupted with symptoms that may be prodromal or a manifestation of a hypertensive crisis, such as palpitations or headaches, and patients should be evaluated immediately.
Discontinue tranylcypromine tablets, other drugs, foods or beverages suspected to contribute to the hypertensive crisis immediately [see Drug Interactions (7.1, 7.2)] . Patients with severe elevations in blood pressure (e.g., more than 180/120 mm Hg) with evidence of organ dysfunction require immediate blood pressure reduction. Fever should be managed by means of external cooling. However, additional measures to control the causes of hyperthermia (psychomotor agitation, increased neuromuscular activity, persistent seizures) may be required.
5.3Serotonin Syndrome
The development of a potentially life-threatening serotonin syndrome has been reported with MAOIs when used concomitantly with other serotonergic drugs. Such drugs include SSRIs, SNRIs, tricyclic antidepressants, triptans, fentanyl, lithium, tramadol, tryptophan, buspirone, St. John’s wort, S-adenosyl-L-methionine (SAM-e), and other MAOIs used to treat nonpsychiatric disorders (such as linezolid or intravenous methylene blue).
Manifestations of the serotonin syndrome may include mental status changes (e.g., agitation, hallucinations, delirium, coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia; with possible rapid fluctuations of vital signs), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyper-reflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
Fatal outcome of serotonin syndrome has been reported, including in patients who had been treated with tranylcypromine tablets. In some cases of an interaction between tranylcypromine tablets and SSRIs or SNRIs, the features of the syndrome resembled neuroleptic malignant syndrome. The concomitant use, or use in rapid succession, of tranylcypromine tablets with other serotonergic drugs is contraindicated. However, there may be circumstances when treatment with other serotonergic substances (such as linezolid or intravenous methylene blue) is necessary and cannot be delayed.
In such cases, tranylcypromine tablets must be discontinued as soon as possible before initiating treatment with the other agent. Treatment with tranylcypromine tablets and any concomitant serotonergic agents should be discontinued immediately if the above

Interactions
See Full Prescribing Information for a list of products, foods and beverages that can interact with tranylcypromine 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 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.
T ime to Start Tranylcypromine Tablets after Discontinuation of a Contraindicated Drug For products that are contraindicated with tranylcypromine 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 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 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. T ime to Start Contraindicated Drug after Discontinuation of Tranylcypromine Tablets The potential for interactions persists after discontinuation of tranylcypromine 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 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 tablets as soon as possible before initiating treatment with the other agent, and monitor closely for adverse reactions.

7.2Tyramine-Containing Foods and Beverages
Tranylcypromine tablets inhibits intestinal MAO, which is responsible for the catabolism of tyramine in food and beverages. As a result of this inhibition, large amounts of tyramine may enter the systemic circulation and precipitate a sudden elevation in blood pressure or hypertensive crisis [see Warnings and Precautions (5.2)] . Instruct tranylcypromine tablet-treated patients to avoid foods and beverages with significant tyramine content during treatment with tranylcypromine tablets or within 2 weeks of stopping treatment (see Table 5 for a list of food and beverages containing significant amounts of tyramine).

Pregnancy and breastfeeding
8.1Pregnancy Risk Summary
There are limited published reports of placental infarction and congenital anomalies in association with use of tranylcypromine tablets during pregnancy; however, these reports may not adequately inform the presence or absence of drug-associated risk with the use of tranylcypromine tablets during pregnancy. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 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 tablets and drugs or procedures (e.g., epidural anesthesia) should be taken into account in women who have received tranylcypromine tablets [see Warnings and Precautions (5.6) and Drug Interactions (7.1)].
Adverse reactions
The following adverse reactions are described in greater detail in other sections: Suicidal thoughts and behaviors [see Warnings and Precautions (5.1)] Hypertensive crisis and hypertension [see Warnings and Precautions (5.2)] Serotonin syndrome [see Warnings and Precautions (5.3)] Activation of mania/hypomania [see Warnings and Precautions (5.4)] Hypotension [see Warnings and Precautions (5.5)] Hypotension and hypertension during anesthesia and perioperative care [see Warnings and Precautions (5.6)] Discontinuation syndrome [see Warnings and Precautions (5.8)] Persistence of MAO inhibition after discontinuation [see Warnings and Precautions (5.9)] Hepatotoxicity [see Warnings and Precautions (5.10)] Seizures [see Warnings and Precautions (5.11)] Hypoglycemia in diabetic patients [see Warnings and Precautions (5.12)] Aggravation of coexisting symptoms of depression [see Warnings and Precautions (5.13)] Adverse effects on the ability to drive and operate machinery [see Warnings and Precautions (5.14)] Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Based on clinical trial data, the most common adverse reactions to tranylcypromine were dry mouth, dizziness, insomnia, sedation, and headache (>30%) and overexcitement, constipation, blurred vision, and tremor (>10%). The following adverse reactions have been identified in clinical trials or during postapproval use of tranylcypromine tablets: B lood and lymphatic system disorders: agranulocytosis, leukopenia, thrombocytopenia, anemia E ndocrine disorders: impaired water excretion compatible with the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) Me tabolism and nutrition disorders: significant anorexia, weight gain P sychiatric disorders: excessive stimulation/overexcitement, manic symptoms/hypomania, agitation, insomnia, anxiety, confusion, disorientation, loss of libido Nervous system disorders: dizziness, restlessness/akathisia, akinesia, ataxia, myoclonic jerks, tremor, hyper-reflexia, muscle spasm, paresthesia, numbness, memory loss, sedation, drowsiness, dysgeusia, headaches (without blood pressure elevation) Ey e disorders: blurred vision, nystagmus E ar and labyrinth disorders: tinnitus Cardiac disorders: tachycardia, palpitations V ascular disorders: hypertensive crisis, hypertension, hypotension (including postural hypotension with syncope) G astrointestinal disorders: diarrhea, constipation, nausea, abdominal pain, dry mouth, fissuring in corner of mouth He patobiliary disorders: hepatitis, elevated aminotransferases Skin and subcutaneous tissue disorders: localized scleroderma, flare-up of cystic acne, urticaria, rash, alopecia, sweating Re nal and urinary disorders: urinary retention, urinary incontinence, urinary frequency Re productive system and breast disorders: impotence, delayed ejaculation General disorders and administration site conditions: edema, chills, weakness, fatigue/lethargy Most common adverse reactions (>10%) were dry mouth, dizziness, insomnia, sedation, headache, overexcitement, constipation, blurred vision, and tremor (6) To report SUSPECTED ADVERSE REACTIONS, contact Novitium Pharma LLC at 1-855-204-1431 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
