Cogentin is an injectable prescription medication used to treat symptoms of Parkinson’s disease or involuntary movements caused by certain psychiatric drugs (antipsychotics).

Cogentin contains benztropine mesylate. Benztropine mesylate belongs to the class of anticholinergic agents and works by blocking the action of acetylcholine, a neurotransmitter, which is responsible for the contraction of muscles and function of various organs. In turn, Cogentin helps to reduce parkinsonian-like symptoms like tremors, muscle stiffness, and slow movements, which are caused by an imbalance of acetylcholine and dopamine in the brain.

It is typically administered as an injection and is available in a 1 mg per mL dosage strength. Your doctor will direct you to take Cogentin either by injection into a vein or into a muscle 2 to 4 times a day, or as a single dose at bedtime. If you are self-administering this medication, be sure to follow all preparation and usage instructions provided by your healthcare professional.

Before using Cogentin, visually check the product for any particles or discoloration. If you see either, do not use the liquid. To minimize the risk of side effects, your doctor may start you on a low dose and slowly increase it. The dosage amount will depend on your age, medical condition, and response to treatment.

Use Cogentin regularly at the same time(s) each day to gain maximum benefit. Your doctor may recommend that you take this medication on a regular schedule or only as needed if you are using it for medication-induced side effects. If you are taking it for Parkinson’s disease, your doctor may change the dosage of other medications you are taking, such as levodopa.

If you use Cogentin injection for a prolonged period, it may lose its effectiveness. In this case, discuss this with your doctor.

While Cogentin is helpful for many people, it may pose a risk of addiction. Inform your doctor if you have a history of substance use disorder and be sure to take it as prescribed to reduce the likelihood of addiction. Do not increase the dose, take it more frequently or for a longer duration than advised. Discontinue its use in the manner directed by your doctor, as stopping its use abruptly can exacerbate some medical conditions.

It may take 2-3 days before you experience the therapeutic effects of Cogentin. Contact your doctor if your condition persists or deteriorates.
