Hi: This is a first time post so... My dad has just started taking Resperidol to try to control paranoic delusions caused by his PD medications. Really what we tried to convince the doctor to prescribe is Clauzapine which was recommended by Dr. Greene of Columbia Presbertarian(sp?). However, his doctor wanted to try Resperidol first. Has anybody have any experience with any of those drugs? I would love to know your thoughts . . . Yael Moverman & Elik Hirsch for Michael (Sister and Brother for Dad)
