Benztropine Mesylate Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Benztropine mesylate is used as an adjunct treatment in the therapy of all forms of Parkinsonism. It is also used to help control extrapyramidal disorders, which are side effects that may result from taking anti-psychotic medications. It is an anti-Parkinson's agent and anticholinergic agent. This medication is available in generic form. Common side effects include rapid heart rate, constipation, vomiting, nausea, dry mouth, confusion, visual hallucinations, nervousness, depression, blurred vision, or problems with urination.

To treat Parkinson's disease, the usual daily dose of benztropine mesylate is 1 to 2 mg, with a range of 0.5 to 6 mg orally or parenterally. In treating extrapyramidal disorders due to neuroleptic drugs (e.g., phenothiazines), the recommended dosage is 1 to 4 mg once or twice a day orally or parenterally. Benztropine mesylate may interact with antipsychotic drugs, or antidepressants. Tell your doctor all medications and supplements you use. Safe use in pregnancy has not been established. Consult your doctor before breastfeeding.
