Effexor (Venlafaxine) is a common antidepressant medication that is classified as an SNRI. It functions by preventing reuptake of the neurotransmitters serotonin and norepinephrine. I was on Effexor XR 150mg daily for many years. It was a miracle drug. Got rid of depression, anxiety and panic attacks. No side effects except weight gain. The symptoms of anxiety vary for each person, based on the specific anxiety disorder a person has. However, all anxiety disorders are linked together by common symptoms, including excessive, irrational fear and dread. A healthy liver aids the digestion of fats and proteins, regulates sex hormones, breaks down toxins in the bloodstream and removes excess red blood cells. Question: A friend has been on Effexor XR for a few years now, but the doctor wants her to get on Welbutrin to help her stop smoking. Can she take both Welbutrin and Effexor XR together if she cuts the Effexor XR to 75 from 150, and will this give her the desired effect of both? Venlafaxine (Effexor) is a prescription drug used to treat major depression, anxiety, social phobia, and panic disorder. Venlafaxine, sold under the brand name Effexor among others, is an antidepressant medication of the serotonin-norepinephrine reuptake inhibitor (SNRI) class. It is used to treat major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder, and social phobia. It is taken by mouth. In the past I took myself off 150mg daily Effexor XR and had bad withdrawals for 2 weeks. After that I was fine. I lost all the weight I had gained whilst on Effexor, which was why I stopped it.
