Abilify didn't cause it for me, but Risperidone certainly does. I was on a high dose for a couple of years, and now my psychiatrist has reduced the dose by 75% because my hands were shaking so much. In addition, she's switching me over to Latuda, which has less of this problem. I have a friend with bipolar whose hands shake like crazy due to all the years of sketchy medications. He had hardly lift a glass to drink or use a pen or pencil. This is a real problem, and if your meds are causing it, get off those meds!
