Special warnings about Effexor

In clinical studies, antidepressants increased the risk of suicidal thinking and behavior in children and adolescents with depression and other psychiatric disorders. Anyone considering the use of Effexor or any other antidepressant in a child or adolescent must balance this risk with the clinical need. Effexor has not been studied in children or adolescents and is not approved for treating anyone less than 18 years old.

Additionally, the progression of major depression is associated with a worsening of symptoms and/or the emergence of suicidal thinking or behavior in both adults and children, whether or not they are taking antidepressants. Individuals being treated with Effexor and their caregivers should watch for any change in symptoms or any new symptoms that appear suddenly--especially agitation, anxiety, hostility, panic, restlessness, extreme hyperactivity, and suicidal thinking or behavior--and report them to the doctor immediately. Be especially observant at the beginning of treatment or whenever there is a change in dose.
