My sister is weaning off of Effexor, as per her new doc's orders, (She's bi-polar) and he put her on Welbutrin. Is there any known side effects to being on both med's at the same time? the doc (psyc) wasn't too interested in her concerns, he was just in a hurry to prescribe med's, ERGGG!. I usually check med interactions at Drugdigest.com, but their site isn't working tonight for some reason. So thought I'd post here. Does anyone have experience with these 2 med's together? Thanks in advance!
