On bupropion xl 150mg couple months gained weight, was on paxil50mg too but recently switched from paxil to 60mgprozac,possibly gained from bupropion?

Bupropion wt gain?: Bupropion is an antidepressant not likely to cause weight gain vs. SSRI's (eg. Prozac and Paxil). That said, weight gain is reported as an uncommon side effect of bupropion. If weight gain continues on Prozac, would consider Effexor. Discuss with prescribing doctor. Meantime, eat healthy foods, exercise regularly and keep track of your weight. I hope this helps. Best wishes.
