I was told there is a drug called Dofran (generic name Ondansetron) which originated in Israel. Apparenly it is used frequently for chemotherapy patients but also reportedly has been helpful with Parkinson patients. I read LDopa causes many psychiatric problems (i.e. no sleep, confusion, paranoia, etc.) and this apparently counteracts these types of symptoms. Is anyone here familiar with this medication? Is it available in the USA? How is this medication? Has anyone had any experiences with it? I'm interested in all responses and am real interested in hearing how familiar the medical community is with it. Hopefully I'm on to something which may help my dad who has Parkinson's and may help lots of people... Mark Gottlieb
