Dose-dependent olanzapine-induced myoclonus.

Second-generation antipsychotics (SGA), mainly clozapine have been reported to induce myoclonus. Although olanzapine-induced myoclonus is reported, dose-dependent response has not been described. We report dose-related olanzapine-induced myoclonus in an early onset schizophrenia patient. We also suggest certain management strategies for such adverse side effects.
