Cogentin (benztropine) is a medication used to treat symptoms of Parkinson's disease and involuntary movements caused by certain psychiatric drugs.

Benztropine belongs to a class of drugs called anticholinergics, which work by blocking the action of a natural substance called acetylcholine.

In Parkinson's disease, Benztropine helps to:

  • Reduce muscle stiffness
  • Decrease sweating
  • Improve walking ability

It can also stop severe muscle spasms and decrease muscle stiffness caused by psychiatric medications.


  • Take Cogentin orally as prescribed by your healthcare provider, usually 2 to 4 times a day with meals and at bedtime, or as a single dose at bedtime. 
  • Measure your dose with a special measuring spoon or device to ensure accuracy if using the oral solution. 
  • Take Cogentin regularly at the same time each day to optimize its effectiveness and aid in remembering to take it. 
  • Take Cogentin at least 1 hour before antacids containing magnesium, aluminum, or calcium. 
  • Allow at least 1-2 hours between doses of Cogentin and certain drugs for diarrhea (adsorbent antidiarrheals such as kaolin, pectin, and attapulgite). 
  • Take Cogentin at least 2 hours after ketoconazole to avoid interactions. 
  • Follow your healthcare provider's instructions closely. 
  • Talk to your healthcare provider if you notice that the medication is no longer effective. 


  • Do not use a household spoon to measure Cogentin oral solution, as it may not provide the correct dose. 

The dosage and administration of Cogentin (benztropine) may vary depending on the individual's medical condition, age, and response to therapy. Your healthcare provider may start you at a low dose and gradually increase it to find the best dose for you. Antacids and some drugs for diarrhea may affect the absorption of Cogentin or the absorption of other medications when taken together. If you are taking Cogentin for Parkinson's disease, your healthcare provider may adjust the dose of your other medications, such as levodopa. When Cogentin is used for a long time, it may not work as well.
