WHY is this medicine prescribed?
Benztropine is used along with other medications to treat the symptoms of Parkinson's disease (PD; a disorder of the nervous system that causes difficulties with movement, muscle control, and balance) and tremors caused by other medical problems or medications. Benztropine is in a class of medications called anticholinergics. It works by blocking a certain natural substance (acetylcholine) to help to decrease symptoms in people with Parkinson's disease.
HOW should this medicine be used?
Benztropine comes as a tablet to take by mouth. It usually is taken at bedtime. It is usually taken once daily but may be taken up to four times a day depending on your symptoms. Take benztropine at around the same time(s) 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 benztropine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start with a small dose and increase it slowly after seeing your response to benztropine. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
Do not stop taking benztropine 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.

To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
