I've been on Wellbutrin SR(generic form Bupropion) since June4th of this year. I was having increased anxiety with the Sr so the doctor put me on the Wellbutrin 150mg XL(Bupropion). The anxiety and depression has gotten a little bit better but the hair loss.....OMG! I wasn't expecting this at all! My hair was already thin with age but I now have a whole lot less of it! Do you all think it's the generic form of the medication that's the problem? On another matter of weight, well most people lose weight while on this medication but not me of course. I gained weight! I was already obese and now I'm 10lbs heavier. Anybody out there with these similar problems?
