Benztropine is used with other medicines to treat symptoms of Parkinson's disease, such as stiffness or tremors.

Benztropine is also used to treat Parkinson-like symptoms caused by using certain medicines.

Benztropine may also be used for purposes not listed in this medication guide.

Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.

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.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Benztropine is usually taken at bedtime.

Benztropine injection is given in a muscle or vein if you are unable to take the medicine by mouth.

Dry mouth may lead to gum disease or cavities. Brush and floss your teeth regularly and visit your dentist for routine dental care.

Call your doctor if your symptoms do not improve, or if they get worse.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. 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. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

Unless your doctor tells you otherwise, continue your normal diet.

Avoid driving or hazardous activity until you know how benztropine will affect you. Your reactions could be impaired.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Benztropine can decrease sweating and you may be more prone to heat stroke.

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
