Thank you for all the response. I am sorry I gave you the wrong idea. It is my husband who has PD. He was on the same medication since he was diagnosed, seven years ago, Four Sinemet 25/100 and two Eldepryl 5 mg. a day. When the hallucinations started and we were not getting answers from his neurologist we changed to another. He took him off the Eldepryl. It took about two weeks and he could not get out of the chair. He needed to be in a wheelchair. This doctor put him back on one Eldepryl a day. Movement better. We then started on anti psychotic pills, Olanzapine, Seroquel, Mellaril. Each separately for a few weeks with no results. Now we are taking Risperdal, with his Sinemet and Eldepryl. Have just increased the Risperdal to 4 mg. a day. Still hallucinating. Will stay on this for awhile because I believe we didn't give the other antipsychotics a chance. Sorry this is so long. We do appreciate your input. Grace
