Effexor Side Effects

As an antidepressant, Effexor works to increase levels of serotonin in the brain. Serotonin is thought to produce feelings of happiness in well-being. In patients with depression, the levels of serotonin are often lower than the general population. Doctors prescribe Effexor to treat major depression, panic disorder and anxiety disorder. Individuals who are allergic to venlafaxine should never take Effexor.

Patients should never take Effexor if they have cirrhosis of the liver, kidney disease, glaucoma, seizures or high blood pressure. Anyone who has recently taken an MAOI should wait at least two weeks before switching to Effexor. This drug can also cause complications if it is taken with desvenlafaxine. Individuals who have a blood clotting disorder, epilepsy, bipolar disorder or high cholesterol should also consult with a doctor before they start taking Effexor.
