Procyclidine is a prescription medicine that can help treat the symptoms of Parkinson's disease and movement disorders (extrapyramidal symptoms) that are caused by antipsychotic medications. This medication can also treat excessive drooling caused by Parkinson's disease or antipsychotic medications. As an anticholinergic medication, procyclidine works by re-establishing the normal balance of certain chemicals within the nervous system. Common side effects include constipation, nausea, and blurred vision.
