Antidepressants may increase risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (18–24 years of age) with major depressive disorder and other psychiatric disorders; balance this risk with clinical need. Phenelzine is not approved for use in pediatric patients. (See Pediatric Use under Cautions.)
In pooled data analyses, risk of suicidality was not increased in adults >24 years of age and apparently was reduced in adults ≥65 years of age with antidepressant therapy compared with placebo.
Depression and certain other psychiatric disorders are themselves associated with an increased risk of suicide.
Appropriately monitor and closely observe all patients who are started on phenelzine therapy for clinical worsening, suicidality, or unusual changes in behavior; involve family members and/or caregivers in this process. (See Worsening of Depression and Suicidality Risk and also Pediatric Use, under Cautions.)
