After trying a few different anti-depressants for my migraines, my neurologist decided to try Effexor. Within a matter of few, I began to experience side effects, including weight gain. When I questioned my doctor about this, he felt it was unlikely that Effexor was the cause. So, I assumed it must be other meds I was on and continued to take it. Well, the side effects, including the weight gain worsened. That was when I found this site and also the more extensive list of side effects than you get with your prescription. Wow. All the issues I was having were from this drug - not just the weight gain, but the urinary frequency, the fatigue, the digestive problems, the allergy-like symptoms, all of it. Needless to say, I called my doctor and told him I was stopping the Effexor. It took over a month to taper-off of the drug and most of the side effects are gone, but I have still been unable to lose any of the weight. It is so frustrating. I put on 15 pounds in 3 months despite watching what I eat and working out regularly. Does anyone have any advice for how they have lost the weight they gained? Also, why aren't all of these side effects included with the drug information?
