TARDIVE-DYSKINESIA INDUCED BY SULPIRIDE

Although tardive dyskinesia is a known adverse reaction of sustained treatment with traditional neuroleptic agents, it was only rarely reported in association with sulpiride, a selective D2-receptor antagonist. We describe six patients who developed tardive dyskinesia after treatment with sulpiride for depression or gastrointestinal symptoms. In three patients, involuntary movements emerged during the course of treatment and in the others only after discontinuation of the drug. These cases indicate that sulpiride can cause tardive dyskinesia and that this drug should be administered with caution.
