For the Consumer

Applies to tranylcypromine: oral tablet


Oral route (Tablet)

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 sulfate is not approved for use in pediatric patients.Excessive consumption of foods or beverages with significant tyramine content or the use of certain drugs with tranylcypromine sulfate or after tranylcypromine sulfate discontinuation can precipitate hypertensive crisis. Monitor blood pressure and allow for medication-free intervals between administration of tranylcypromine sulfate and interacting drugs. Instruct patients to avoid ingestion of foods and beverages with high tyramine content.
