A case of levosulpiride-induced tardive dyskinesia

Levosulpiride is chemically a substituted benzamide which acts as an atypical antipsychotic and prokinetic agent. There is dearth of study and limited research on levosulpiride-induced tardive dyskinesia (TD) and its abuse potential till date. Levosulpiride can cause TD which is related to an apparent dopaminergic hyperactivity after long-term blockade of presynaptic dopaminergic D2 receptors. So, detailed drug history should be taken to detect the rare cases of levosulpiride-induced TD and physicians should be cautious in using levosulpiride, particularly in elderly patients.
