“ALERT: US Boxed Warning
Suicidality and antidepressant drugs:
Compared with placebo, antidepressants increase the risk 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. Anyone considering the use of clomipramine or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared with placebo in adults older than 24 years; there was a reduction in risk with antidepressants compared with placebo in adults 65 years and older. Depression and certain other psychiatric disorders are associated with increased risk of suicide. Appropriately monitor patients of all ages who are started on antidepressant therapy and observe closely for clinical worsening, suicidality, or unusual changes in behavior. Advise families and caregivers of the need for close observation and communication with the prescriber. Clomipramine is not approved for use in pediatric patients except for patients with obsessive-compulsive disorder (OCD).”
