Procyclidine (Procyclidine hydrochloride) — Uses, Dosage, Side Effects & Safety

Drug class: Neurology

Overview

Procyclidine is a medication used to treat symptoms of Parkinson’s disease and movement disorders caused by certain medications, especially antipsychotics. It helps control muscle stiffness, tremors, spasms, and poor muscle control. Procyclidine works by blocking the action of acetylcholine, a natural chemical in the brain that can become imbalanced in Parkinson’s disease or after taking some psychiatric medications. By restoring this balance, procyclidine helps improve movement and reduce unwanted muscle activity. Key points for patients: Take procyclidine exactly as prescribed. It may take several days to notice improvement. Do not stop taking it suddenly without consulting your doctor, as symptoms may return or worsen.
