Effexor is a prescription antidepressant that has been on the market for many years. It is a selective serotonin reuptake inhibitor, also known as an SSRI. It was a medication that was approved by the FDA and introduced to the market by Wyeth in 1993. It was approved for the treatment of generalized anxiety disorder and anxiety disorders with depression in adults. It has also been approved and been successful in treating obsessive compulsive disorder, panic attacks, and social anxiety disorders in children and adults. In 2007 Effexor was the sixth most commonly prescribed antidepressant in the market with almost 17.2 million prescriptions written and filled.

Like most medications, Effexor may be associated with unwanted side effects. Most of these side effects are self limiting and not bothersome enough for most patients to discontinue therapy. Some of the more common side effects include but are not limited to nausea, problems with erectile function, insomnia, diarrhea, dry mouth, tremor, dizziness, and changes in libido. These side effects will usually dissipate over time so that patients did not need to stop therapy. Patients and doctors should discuss all side effects as they occur. Children who take the medication should be carefully watched for signs of suicidal ideation and self harm.

Effexor is not a medication that can be stopped suddenly. The body does become dependent upon the medication and when stopped suddenly withdrawal syndrome can result. Those who wish to discontinue Effexor should talk to their doctor about how to do this safely and effectively. The medication usually needs to be tapered slowly to avoid the withdrawal symptoms that can be very uncomfortable.
