Understanding Depression Slideshow

Effexor XR is approved for the treatment of adults with panic disorder.

SIDE EFFECTS: Venlafaxine, like most anti-depressants, can cause:

Other side effects that can occur are:

Increased blood pressure can occur, and blood pressure should be monitored.

Seizures have been reported.

The FDA suggests if anti-depressants are discontinued abruptly, symptoms may occur such as dizziness, headache, nausea, changes in mood, or changes in the sense of smell, taste, etc. (Such symptoms even may occur when even a few doses of anti-depressant are missed.) Therefore, it is generally recommended that the dose of anti-depressant be reduced gradually when therapy is discontinued.

Antidepressants increased the risk of suicidal thinking and behavior (suicidality) in short-term studies in children, adolescents, and young adults with depression and other psychiatric disorders. Anyone considering the use of venlafaxine or any other antidepressant in a child or adolescent must balance this risk with the clinical need. Patients who are started on therapy should be closely observed for clinical worsening, suicidality, or unusual changes in behavior.
