Weight gain is a known common side-effect of
Abilify. I have attended inservices with
Abilify marketers where weight management techniques (diet and exercise) were emphasized. As suggested, speak with your doctor about it. If it becomes a problem, maybe a weight-neutral antidepressant (Wellbutrin, for example) would be equally effective. However, it's important to continue to take the meds as prescribed while discussing your concerns with your MD.
