Generic Name: fluvoxamine (Oral route)
Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder (MDD) and other psychiatric disorders in short-term studies. Short term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24, and there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. This risk must be balanced with the clinical need. Monitor patients closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber . Fluvoxamine maleate tablets are not approved for use in pediatric patients except for patients with obsessive compulsive disorder (OCD) .
