I was on Risperadol and gained a substantial amount of weight. I was on many different anti depressants at the same time including Wellbutrin.

My medicines went through many changes, but my weight was now up and I believe it was due to risperadol and tofrinal(spelling sorry).

Anyways, I'm now on Wellbutrin and none of those other meds and don't have weight gain issues.

My point of saying I was on Wellbutrin and Risperadol at the same time is ...is that it didn't counteract the weight issue. It seems when certain meds that are known to cause weight gain ... the other meds that "may" be helpful to lose weight ...aren't usually strong enough to win that battle.

Risperadol is one of those meds unfortunately.

Only thing is I would definately discuss this with your doctor first before you mess around with meds. Discuss that this is really making you uncomfortable etc.
