My mother, age 70, has been taking Parkinson medications (Sinemet) for three years. This past weekend she had several instances of hallucinations. Her family doctor who works closely with her neurologist prescribed 1mg of Haldol, twice a day. I have read messages that seem to indicate that Haldol could cause problems to PD patients, under certain circumstances. Does anyone have any information on this subject? - Dan Meyers [log in to unmask]
