What is biperiden (Akineton)?

Biperiden reduces the effects of certain naturally occurring chemicals in your body that may become unbalanced as a result of disease (such as Parkinson's disease), drug therapy, or other causes.

Biperiden is used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinson's disease. It is also used to treat and prevent these same muscular conditions when they are caused by drugs such as chlorpromazine (Thorazine), fluphenazine (Prolixin), perphenazine (Trilafon), and others.

Biperiden may also be used for purposes other than those listed in this medication guide.
