Side Effects of the Use of Benztropine Mesylate

Benztropine mesylate is commonly marketed under the brand name Cogentin. It is often prescribed to Parkinson's disease patients. Although Parkinson's disease has no cure, benztropine mesylate may help control some of its symptoms, such as tremors. Benztropine mesylate is a type of medication called an anticholingeric. It works by acting upon a chemical in the brain, called acetylcholine. Diminishing the effects of this chemical can reduce Parkinson's symptoms. Before taking any medication, discuss the possible side effects with your doctor.
