“ALERT: US Boxed Warning
Suicidal thoughts and behaviors:
Antidepressants increased the risk of suicidal thoughts and behaviors 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. Tranylcypromine is not approved for use in pediatric patients.
Hypertensive crisis with significant tyramine use:
Excessive consumption of foods or beverages with significant tyramine content or the use of certain drugs with tranylcypromine or after tranylcypromine discontinuation can precipitate hypertensive crisis. Monitor blood pressure and allow for medication-free intervals between administration of tranylcypromine and interacting drugs. Instruct patients to avoid ingestion of foods and beverages with high tyramine content.”
How does this medication work?
Tranylcypromine, Parnate is a nonhydrazine inhibitor of monoamine oxidase (MAO) in the central nervous system, which plays a major role in the catabolism of dopamine, epinephrine, and serotonin.
How should I take this medication?
Oral: 10-60mg per day in divided doses
How to Take: Follow instructions provided by physician/pharmacy label, take consistently at same time each day unless otherwise directed, store at room temperature.
You Need to Avoid: Alcohol may increase toxic effects of MAO inhibitors and should be avoided. Concurrent ingestion of foods rich in tyramine, dopamine, tyrosine, phenylalanine, tryptophan, or caffeine may cause sudden and severe high blood pressure (hypertensive crisis or serotonin syndrome).
Management: Avoid foods containing high amounts (>150 mg) of tyramine (aged or matured cheese, air-dried or cured meats including sausages and salamis; fava or broad bean pods, tap/draft beers, Marmite concentrate, sauerkraut, soy sauce, and other soybean condiments). Food’s freshness is also an important concern; improperly stored or spoiled food can create an environment in which tyramine concentrations may increase. Avoid these foods during and for 2 weeks after discontinuation of medication.
When discontinuing antidepressant treatment that has lasted for >3 weeks, gradually taper the dose to minimize withdrawal symptoms and detect reemerging symptoms. If intolerable withdrawal symptoms occur, resume the previously prescribed dose and/or decrease dose at a more gradual rate.
