This question is complicated by the fact that you apparently are psychotic. If you are, then you need to see your psychiatrist about this and perhaps change medications. A psychiatrist can also tell you what might be safe to take with this drug. Antipsychotics generally affect dopamine, and dopamine controls a lot of our motor functions, so it's often a cause of nerve problems or involuntary movements. If you're not in fact psychotic, you may be on too much drug for what ails you. What's your diagnosis?
