Effexor Xr Drug Information:

Effexor (venlafaxine) is an antidepressant belonging to a group of drugs called selective serotonin and norEpinephrine reuptake inhibitors (SSNRIs). Venlafaxine affects chemicals in the brain that may be unbalanced in people with depression. Venlafaxine is used to treat major depressive disorder, anxiety and panic disorder. You should not take Effexor if you have uncontrolled narrow-angle glaucoma, or if you are being treated with Methylene Blue injection. Do not use Effexor within 7 days before or 14 days after you have used a MAO inhibitor, such as isocarboxazid, Linezolid, Methylene Blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.

For the Consumer

Applies to venlafaxine: oral capsule extended release, oral tablet, oral tablet extended release


Oral route (Capsule, Extended Release)

Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies. These studies did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in patients older than 24 years; there was a reduction in risk with antidepressant use in patients aged 65 or older. In patients of all ages who are started on antidepressant therapy monitor closely for clinical worsening and emergence of suicidal thoughts and behaviors. Venlafaxine is not approved for use in pediatric patients.

Oral route (Tablet; Tablet, Extended Release)

Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults in short-term studies with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults older than 24 years, and there was a reduction in risk with antidepressants compared with placebo in adults aged 65 or 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. Not approved for use in pediatric patients
