Lisaben,

I do not have schizophrenia but do have bipolar I. I take Invega which is in the same class of drugs, the atypical antipsychotics. Some of the newer ones, have fewer such side effects.

I do have similar movements, and my doctor put me on Cogentin for it. It helps but does not 100% eliminate them. In my case, the movements are in my feet and hands (mostly feet), occasionally the face. I also have some restlessness. I would say it's 80-90% improved. It's important for him to talk to his doctor.
