I've been taking WellbutrinXL 150mg for about 6 months (also Celexa for over a year) and about 2 months ago my hair started to fall out. Much more than ever before. I have read that both Wellbutrin & Celexa can cause hair loss but am wondering if others have had this side effect? My hair is definitely thinning on top and my hair stylist said I should investigate what it is that is causing this. I also lost 45 lbs in less than 4 months on weight watchers. I started Wellbutrin around the same time as Weight Watchers and I'm sure Wellbutrin helped me with my weight loss. My question is.....of the above...which would be more likely to cause the hair loss. I do take thyroid meds but my levels are good, and my ferritin levels are good. My B12 is actually high so thats not it. Thanks for any advice.
