TRANYLCYPROMINE SULFATE: Package Insert and Label Information (Page 3 of 4)

7.2 Tyramine-Containing Foods and Beverages

Tranylcypromine Sulfate 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 sulfate-treated patients to avoid foods and beverages with significant tyramine content during treatment with tranylcypromine sulfate or within 2 weeks of stopping treatment (see Table 5 for a list of food and beverages containing significant amounts of tyramine).

Table 5: Foods and Beverages with and without Significant Amounts of Tyramine

Class of Food or Beverage Tyramine-Rich Foods and Beverages to Avoid Acceptable Foods and Drinks, Containing No or Little Tyramine
Meat, Poultry, and Fish Air dried, aged and fermented meats, sausages and salamis (including cacciatore, hard salami and mortadella); pickled herring; and any spoiled or improperly stored meat, poultry, and fish (e.g., foods that have undergone changes in coloration, odor, or become moldy); spoiled or improperly stored animal livers Fresh meat, poultry, and fish, including fresh processed meats (e.g., lunch meats, hot dogs, breakfast sausage, and cooked sliced ham)
Vegetables Broad bean pods (fava bean pods) All other vegetables
Dairy Aged cheeses Processed cheeses, mozzarella, ricotta cheese, cottage cheese, and yogurt
Beverages All varieties of tap beer and beers that have not been pasteurized so as to allow for ongoing fermentation and excessive amounts of caffeine. Concomitant use of alcohol with PARNATE is not recommended. (Bottled and canned beers and wines contain little or no tyramine.)
Other Concentrated yeast extract (e.g., Marmite), sauerkraut, most soybean products (including soy sauce andtofu), OTC supplements containing tyramine, and chocolate Brewer’s yeast, baker’s yeast, soy milk, commercial chain restaurant pizzas prepared with cheeses low in tyramine


8.1 Pregnancy

Risk Summary

There are limited published reports of placental infarction and congenital anomalies in association with use of tranylcypromine sulfate during pregnancy; however, these reports may not adequately inform the presence or absence of drug-associated risk with the use of tranylcypromine sulfate 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

[see Warnings and Precautions (5.6) and Drug Interactions (7.1)].

8.2 Lactation

Risk SummaryTranylcypromine is present in human milk. There is no available information on the effects of tranylcypromine on milk production. There is no available information on the effects of tranylcypromine on a breastfed child; however, because of the potential for serious adverse reactions in a breastfed infant, advise nursing women to discontinue breastfeeding during treatment with tranylcypromine sulfate.

8.4 Pediatric Use

Safety and effectiveness of tranylcypromine sulfate in the pediatric population have not been established. All risks associated with the use of tranylcypromine sulfate, including the risk of suicidal thoughts and behavior, apply to adults and pediatric patients [see Boxed Warning and Warnings and Precautions (5)].

8.5 Geriatric Use

Older patients may be at greater risk of postural hypotension and other serious adverse reactions [see Warnings and Precautions (5)]. In general, dose selection for an elderly patient should be cautious, 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.


9.2 Abuse

Abuse of tranylcypromine sulfate has been reported. Some of these patients had a history of previous substance abuse.

The potential for abuse and the increased risk of serious adverse reactions with higher doses should be taken into account when considering the use of tranylcypromine sulfate for patients at increased risk for substance abuse.

9.3 Dependence

Dependence, evidenced by precipitation of withdrawal effects following abrupt discontinuation of tranylcypromine sulfate has been reported. Reported withdrawal effects included delirium (even with low daily doses), restlessness, anxiety, confusion, hallucinations, headache, weakness, diarrhea, and/or rapid relapse into depression. Thrombocytopenia and liver enzyme increases have also been observed in association with tranylcypromine sulfate withdrawal from high doses [see Overdosage (10.1)]

Withdrawal effects have appeared within 1 to 3 days of discontinuation and have persisted for several weeks after discontinuation. The use of daily doses greater than recommended and longer duration of use appear to be associated with a higher risk of withdrawal effects.

Monitor for withdrawal effects for at least 1 week after discontinuation. Consider discontinuing tranylcypromine sulfate therapy by slow, gradual dose reduction [ see Dosage and Administration (2.3)].


10.1 Overdosage Symptoms, Signs, and Laboratory Abnormalities

Overdose of tranylcypromine sulfate can cause the adverse reactions generally associated with tranylcypromine sulfate administration [see Warnings and Precautions (5) , Adverse Reactions (6) and Drug Interactions (7.1)]. However, these reactions may be more severe, including fatal reactions. Effects reported with overdosage of tranylcypromine sulfate and/or other MAOIs include:

  • Insomnia, restlessness, and anxiety, progressing in severe cases to agitation, mental confusion, and incoherence; delirium; seizures
  • Hypotension, dizziness, weakness, and drowsiness, progressing in severe cases to extreme dizziness and shock
  • Hypertension with severe headache and other symptoms/complications
  • Twitching or myoclonic fibrillation of skeletal muscles, with hyperpyrexia, sometimes progressing to generalized rigidity and coma

10.2 Overdosage Management

There are no specific antidotes for tranylcypromine sulfate. For current information on the management of poisoning or overdosage, contact a poison control center at 1-800-222-1222.
Abrupt withdrawal of tranylcypromine sulfate following overdosage can precipitate withdrawal symptoms, including delirium [see Warnings and Precautions 5.9)and Drug Abuse and Dependence (9.3)].

Medical management should normally consist of general supportive measures, close observation of vital signs, and steps to counteract specific manifestations as they occur [see Warnings and Precautions (5)]. The toxic effects of tranylcypromine sulfate may be delayed or prolonged following the last dose of the drug [see Clinical Pharmacology (12.2)]. Therefore, the patient should be closely observed for at least 1 week.

Data on the dialyzability of tranylcypromine are lacking.

MEDICATION GUIDE Tranylcypromine Sulfate Tablets, USP (TRAN-il-SIP-roe-meen Suhl-feyt)

What is the most important information I should know about Tranylcypromine Sulfate tablets? Tranylcypromine Sulfate tablets can cause serious side effects including:

  • Increase in suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of treatment and when the Tranylcypromine Sulfate dose is changed. Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have, or have a family history of, bipolar illness (also called manic-depressive illness) or suicidal thoughts or actions. Tranylcypromine Sulfate is not for use in children.

How can I watch for and try to prevent suicidal thoughts and actions?

  • Pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed.
  • Call the healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings.
  • Keep all follow-up visits with your healthcare provider as scheduled. Call the healthcare provider between visits as needed, especially if you have concerns about symptoms

Call a healthcare provider right away if you have any of the following symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • attempts to commit suicide
  • new or worse depression
  • new or worse anxiety
  • feeling agitated, restless, angry or irritable
  • panic attacks
  • trouble sleeping
  • new or worse irritability
  • acting aggressive, being angry or violent
  • acting on dangerous impulses
  • an extreme increase in activity or talking (mania)
  • other unusual changes in behavior or mood
  • A sudden, severe increase in blood pressure (hypertensive crisis). A hypertensive crisis can happen when you eat certain foods and drink certain beverages during or after Tranylcypromine Sulfate treatment. A hypertensive crisis can lead to stroke and death. People who have thyroid problems (hyperthyroidism) may have a higher chance of having a hypertensive crisis. Symptoms of a hypertensive crisis may include:
  • sudden, severe headache
  • nausea
  • vomiting
  • stiff or sore neck
  • a fast heartbeat (palpitations) or a change in the way your heart beats
  • excessive sweating, sometimes with fever or cold, clammy skin
  • the pupils in your eyes increase in size
  • light bothers your eyes
  • fast or slow heart beat with chest pain
  • bleeding in your brain

A hypertensive crisis can also happen if you take Tranylcypromine Sulfate with certain other medicines. See, “Who should not take Tranylcypromine Sulfate?”
Avoid foods and drinks with a lot of tyramine while taking Tranylcypromine Sulfate and for 2 weeks after you stop taking it. For a list of some of the foods and drinks you should avoid during treatment with Tranylcypromine Sulfate see, “What should I avoid while taking Tranylcypromine Sulfate?”

What is Tranylcypromine Sulfate?
Tranylcypromine Sulfate is a prescription medicine used to treat adults with a certain type of depression called major depressive disorder (MDD) who have not responded well to treatment with other medicines used to treat depression (antidepressants). Tranylcypromine Sulfate belongs to a class of medicines called monoamine oxidase inhibitors (MAOIs).

  • It is important to talk with your healthcare provider about the risks of treating depression and the risk of not treating it. Talk with your healthcare provider about all your treatment choices.
  • Tranylcypromine Sulfate is not for use as the first medicine to treat MDD.
  • It is not known if Tranylcypromine Sulfate is safe and effective for use in children.

Who should not take Tranylcypromine Sulfate?
Taking Tranylcypromine Sulfate with certain antidepressants and certain pain, allergy symptom, and cold and cough symptom medicines may cause a potentially life-threatening hypertensive crisis or a problem called serotonin syndrome. See, “What is the most important information I should know about Tranylcypromine Sulfate?” and “What are the possible side effects of Tranylcypromine Sulfate?”

Do not take Tranylcypromine Sulfate if you:

  • take certain medicines, including:
