-Allow a medication free interval of at least a week.
-Initiate tranylcypromine at half the normal starting dose for at least the first week of therapy.

-Antidepressants increased the risk (compared to placebo) of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short term studies of major depressive disorder (MDD) and other psychiatric disorders.
-Balance this risk with the clinical need for treatment.
-Short term studies did not show increased suicidality in adults beyond the age of 24; there was a reduction of risk in patients 65 years and older.
-Depression and certain other psychiatric disorders are themselves associated with increased risk of suicidality.
-Monitor all patients starting antidepressants closely for clinical worsening, suicidality, or unusual behavior changes.
-Advise families and caregivers of the need for close observation and communication with the prescriber.
-This drug is not approved for use in pediatric patients.
