Definition
Tardive dyskinesia is a disorder that involves involuntary movements, especially of the lower face. Tardive means “delayed” and dyskinesia means “abnormal movement.”
Overview, Causes, & Risk Factors
Tardive dyskinesia is a serious side effect that occurs when you take medications called neuroleptics. It occurs most frequently when the medications are taken for a long time, but in some cases it can also occur after you take them for a short amount of time.
The drugs that most commonly cause this disorder are older antipsychotic drugs, including:
- Haloperidol
- Fluphenazine
- Trifluoperazine
Other drugs, similar to antipsychotic drugs, that can cause tardive dyskinesia include:
- Cinnarizine
- Flunarizine (Sibelium)
- Metoclopramide
