Hi Meow, I know your post is an old one here and for that I am sorry but the medication your asking about Zyprexa is an antipsychotic medication usually given to those who have Bipolar disorder, Schizophrenia and related type disorders. I really wonder how any doctor can say that this medication "mimics" PD symptoms as it is to treat a severe mental illness not PD.
