Benztropine injection is used with other medicines to treat Parkinson's disease. By improving muscle control and reducing stiffness, benztropine allows more normal movements of the body as the disease symptoms are reduced. It is also used to control severe reactions to certain medicines that are used to treat nervous, mental, and emotional conditions (e.g., phenothiazine medicine such as prochlorperazine, Compazine®, Mellaril®, Phenergan®, Thorazine®, Trilafon®).
benztropine is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For benztropine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to benztropine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Using benztropine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
The presence of other medical problems may affect the use of benztropine. Make sure you tell your doctor if you have any other medical problems, especially:
A nurse or other trained health professional will give you benztropine in a hospital. benztropine may be given as a shot into one of your muscles or given through a needle placed in one of your veins.
It is important that your doctor check your progress at regular visits to allow changes in your dose and to check for any unwanted effects.
Benztropine injection may cause dizziness, trouble in controlling movements, or trouble in thinking or seeing clearly. Make sure you know how you react to benztropine before you drive, use machines, or do other jobs that require you to be alert, well-coordinated, or able to think or see well.
Do not stop taking benztropine without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping completely.
benztropine may make you sweat less, causing your body temperature to increase. Use extra care to avoid becoming overheated during exercise or hot weather while you are taking benztropine, since overheating may result in heat stroke.
benztropine may cause muscle weakness. If you have concerns about this, check with your doctor.
If you develop any unusual or strange thoughts and behavior while receiving benztropine injection, be sure to discuss it with your doctor.
