What is valbenazine?

Valbenazine blocks certain chemicals in the body that may be involved with involuntary muscle movement.

Valbenazine is used to treat symptoms of tardive dyskinesia, a nervous system disorder. Tardive dyskinesia causes repetitive uncontrolled muscle movements, usually in the face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement). Valbenazine is not a permanent cure for this condition.

Valbenazine may also be used for purposes not listed in this medication guide.
