Benztropine is a prescription medication used to treat symptoms of Parkinson’s disease and tremors caused by other medical conditions or drugs.

Benztropine has anticholinergic and antihistamine effects, though only the anticholinergic properties are therapeutically significant in treating symptoms of Parkinson’s disease. Anticholinergic agents block the binding of a neurotransmitter to nerve cells that are responsible for involuntary movements of smooth muscle cells.

This medication comes in tablet form and is taken up to 3 times a day. Take benztropine with food or milk.

This medication is also available in an injectable form to be given directly into a vein (IV) or a muscle (IM) by a healthcare professional.

Common side effects of benztropine include dry mouth, difficulty urinating, and constipation.

Benztropine can also cause blurred vision, drowsiness, and dizziness. Do not drive or operate heavy machinery until you know how benztropine affects you.
