HI Emily, Compazine is used primarily to control nausea and vomiting. It is however a "phenothiazine". Other drugs in that class include the antipsychotics like chloropromazine(Thorazine), Trifluoperizene (Stelazine) and others. All these drugs block the effect of dopamine. They can cause what are referred to extrapyramidal side effects while someone is taking them. These are symptoms PWP experience. There is no evidence- that I am aware of- that use of these drugs predisposes one to develop PD. However someone with early PD is much more likely to experience the side effects while the taking the drugs. Compazine definitely should not be used by PWP except in very rare cases.
