Hi ya axelsmom, It’s weird but each and every antidepressant on the market has the potential to cause weight gain. I recently saw an article on this very topic that outlined why this occurs with antidepressants. It stated that the reason is because the antidepressants work differently in each person’s body and with their own body chemicals. Some will gain weight and some won’t. I will try to find the article again and post it...I think it was from WebMD.
I didn’t gain with Prozac but did with Zoloft. I am on Effexor XR now and lots of people claim to gain on it but I haven’t. It is very odd how this happens.
