Austedo (deutetrabenazine) decreases the amount of certain substances in the body that are overly active in people with Huntington’s disease. It is used to for people that experience involuntary muscle movements (chorea) caused by Huntington’s disease. Deutetrabenazine is not a cure for Huntington’s disease and will not treat other symptoms of this condition.
Austedo is also used to treat manifestations of tardive dyskinesia, a nervous system disorder. Tardive dyskinesia leads to repetitive uncontrolled muscle movements, usually in the face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement). This drug is not a permanent cure for involuntary movement disorders.
