Suicidality and Antidepressant Drugs
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. Anyone considering the use of EMSAM 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 to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening,suicidality,or unusual changes in behavior.Families and caregivers should be advised for the need for close observation and communication with the prescriber. EMSAM is not approved for use in pediatric patients.Furthermore,EMSAM at any dose should not be used in children under the age of 12, even when administered with dietary modifications. (See WARNINGS: Clinical Worsening and Suicide Risk, PRECAUTIONS: Information for Patients, and PRECAUTIONS: Pediatric Use.)

EMSAM systems are transdermal patches that contain 1 mg of selegiline per cm2 and deliver approximately 0.3 mg of selegiline per cm2 over 24 hours. EMSAM systems are available in three sizes: 20 mg/20 cm2, 30 mg/30 cm2, and 40 mg/40 cm2 that deliver, on average, doses of 6 mg, 9 mg, or 12 mg, respectively, of selegiline over 24 hours.
