In a recent posting to this List, Dr. Usman described Clozapine and Sinemet as a "useful combina- tion for PD patients experiencing hallucinations, etc." My father has been diagnosed with PD and takes Sinemet. He has been experiencing hallucinations, but I am not aware that his physician has recommended Clozapine. Can Dr. Usman or anyone else comment more extensively on this medication? Thanks.
