Dave had very bad hallucinations. They were usually evening and night. He thought the house was on fire or that he was still working and yelled for us to turn off a machine (middle of the night) The neuro put him on Clozaril and they were worse. After I complained and yelled enough (very uncooperative neuro - that's another story, long) Dave was put on Risperdal. It was like a miracle. One day, the, last day on Clozaril, he was hallucinating all evening and all night, as usual. The next day, the first day he took Risperdal, it completely stopped, immediately. Everybody's different. There aren't many of this type of drugs that PWP can take but it might be worth trying another one. I always have to mention a hallucination chuckle. We have a couple of leftover 4-H project dairy goats. Dave was in the dining room and though he saw a horse in the dining room with him (hallucination). About half an hour later, our son went by and Dave asked him what he'd done with the horse. Rich said, "We put it in the barn with the goats." Dave thought that was a good thing to do and was happy.
