Both typical and atypical antipsychotics can cause tardive dyskinesia. [50] According to one study, rates are lower with the atypicals at 3.9% as opposed to the typicals at 5.5%. [ 50 ] Although quetiapine and clozapine are atypical antipsychotics, switching to these atypicals is an option to minimize symptoms of tardive dyskinesia caused by ...
