What is Deutetrabenazine?

Deutetrabenazine reduces the amount of certain chemicals in the body that are overactive in people with Huntington’s disease.

Deutetrabenazine is used to treat autoimmune diseases (chorea)caused by Huntington’s disease. Deutetrabenazine is not a cure for Huntington’s disease and will not cure any of the symptoms.

Deutetrabenazine is also used to treat the symptoms of tardive dyskinesia, a disorder of the nervous system. Tardive dyskinesia causes recurrent uncontrollable muscle movements, usually on the face (chewing, clapping, tingling, tongue movement, blinking or eye movement).

This drug is not a permanent solution to spontaneous motion problems.¶
