Table of contents:

Cogentin generically known as Benztropine is a medication commonly prescribed to treat a variety of neurological conditions, including Parkinson’s disease, extrapyramidal symptoms, tardive dyskinesia, and Tourette’s syndrome. Benztropine belongs to a class of medication called anticholinergics. It works to reduce the amount of dopamine in the brain, thereby relieving symptoms associated with certain conditions.

Cogentin (Benztropine) is a powerful medication used to treat the symptoms of Parkinson’s disease. It is also prescribed off-label to treat a variety of other conditions, such as schizophrenia, autism, and Tourette’s syndrome.

Benztropine helps to decrease muscle stiffness, sweating, and the production of saliva and helps improve walking ability in people with Parkinson's disease. It can also stop severe muscle spasms of the back, neck, and eyes that are sometimes caused by psychiatric drugs. It can also decrease other side effects such as muscle stiffness/rigidity (extrapyramidal signs-EPS).

Uses and Dosage

Benztropine is available as a tablet to be taken orally, typically 2 to 4 times a day with meals and at bedtime, or as a single dose at bedtime. Benztropine should be taken with food or milk to reduce the risk of stomach upset. It should be taken at the same time each day to maintain an even level of the drug in your system.

Take this medication as prescribed by your doctor, as the dosage may need to be adjusted depending on your age, medical condition, and response to the medication. Your doctor may start you on a low dosage and gradually increase it to ensure you are taking the most effective dose for your individual needs.

For Parkinson's disease, the typical dosing for Benztropine (Cogentin) is 0.5 mg to 6 mg taken orally once or twice a day. For extrapyramidal symptoms, the recommended dosage is 1 mg to 4 mg taken orally once or twice a day. Your doctor may start you at a lower dose and gradually increase it to ensure that you are taking the most effective dose for your individual needs.
