Tardive dyskinesia (TD) is a movement disorder characterized by uncontrollable, abnormal, and repetitive movements of the face, torso, and/or other body parts. It can develop as a side effect of medication, most commonly antipsychotic drugs, and certain anti-nausea medications. TD can cause mild to severe twitching, shaking, or jerking in the hands, feet, face, or torso, and involuntary blinking, tongue movements, and facial grimacing. The symptoms of TD often can be persistent and potentially disabling, and may be disruptive to peoples lives due to the symptoms themselves and the impact they have on emotional and social well-being. TD can be hard to diagnose, and symptoms might not appear until months or years after you start taking antipsychotic medicine. The uncontrollable movements may be disruptive to peoples lives due to the symptoms themselves and the impact they have on emotional and social well-being. The U.S. Food and Drug Administration (FDA) has approved valbenazine (Ingrezza) and deutetrabenazine (Austedo) as treatments for TD.
