Sharon, what else are you taking? The Procyclidine is generally prescribed to counter either Parkinson's or tremors, muscle tension, seizures, and other side effects from medications like Haldol, Trilafon, Thorazine, etc.. Either the other meds are over powering the Procyclidine or, your brain does not effectively process/utilize that particular anticholinergic agent. That's just my experiential opinion.
