Quetiapine-induced myoclonus.
We report a case of myoclonus induced by quetiapine. A 64-year-old man with schizophrenia developed myoclonic jerks when given higher doses of quetiapine. These movements were dose-related and completely abated on reducing the dose. To our knowledge, these movements have not been reported previously as an adverse effect of quetiapine.
