Trihexyphenidyl is used to treat the symptoms of Parkinson's disease and tremors caused by other medical problems or drugs.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Trihexyphenidyl comes as a tablet, liquid, and extended-release (long-acting) capsule to take by mouth. It usually is taken three or four times a day (with meals and at bedtime). The controlled-release capsules are taken once a day (after breakfast) or twice a day, every 12 hours. You may have to take trihexyphenidyl for a long time to treat Parkinson's disease. However, trihexyphenidyl may only be needed for a short period to treat other conditions. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take trihexyphenidyl exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Do not stop taking trihexyphenidyl suddenly without talking with your doctor, especially if you are also taking other medications. Sudden stoppage can cause symptoms of Parkinson's disease to return.
Do not open the extended-release capsules and do not chew the tablets. Swallow them whole.
