Procyclidine (patient information)

# Why is this medication prescribed
Procyclidine is used to treat parkinsonism (slowed movements, stiffness of the body, uncontrollable body movements, weakness, tiredness, soft voice, and other symptoms caused by damaged nerves in the brain). Procyclidine is also used to treat problems with moving and drooling that may be caused by certain medications for mental illness. Procyclidine is in a class of medications called antispasmodics or antimuscarinics. It works by preventing sudden tightening of the muscles.

# How should this medicine be used
Procyclidine comes as a tablet to take by mouth. It is usually taken 3 times a day during or after meals and is sometimes also taken at bedtime. Take procyclidine at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take procyclidine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of procyclidine and gradually increase your dose.
Procyclidine may help control your symptoms but will not cure your condition. Continue to take procyclidine even if you feel well. Do not stop taking procyclidine without talking to your doctor.
