Reporte de caso: mioclonias inducidas por quetiapina

Abstract

Quetiapine is an atypical antipsychotic, derived from dibenzothiazepine, widely used for its improved safety profile, particularly in patients with Parkinson's disease. Despite its favorable profile, there have been isolated reports of myoclonus induced by this drug, even at low doses. We present the case of a 71-year-old patient with Parkinson's disease who developed myoclonus after administration of quetiapine at subtherapeutic levels (12.5 mg). The myoclonus completely resolved after discontinuation of the drug and the introduction of clonazepam, highlighting the importance of recognizing this rare adverse effect.
