Trihexyphenidyl — Uses, Dosage, Side Effects & Safety

Drug class: Anticholinergic (Antiparkinsonian agent)

Overview

Trihexyphenidyl is a prescription medication used to treat symptoms of Parkinson's disease and certain movement disorders caused by other medications, such as antipsychotics. It helps reduce muscle stiffness, tremors, and spasms, making movement easier for people with these conditions. Trihexyphenidyl works by blocking the action of acetylcholine, a chemical messenger in the brain that can become overactive in Parkinson's disease. By restoring the balance between acetylcholine and dopamine, it helps control abnormal movements. Patients should know that Trihexyphenidyl does not cure Parkinson's disease but can help manage its symptoms. It is important to take this medication exactly as prescribed and to report any side effects or changes in symptoms to your healthcare provider.
