Carbamazepine-induced dyskinesia and ophthalmoplegia

Author and Disclosure Information


Antiepileptic drug-induced dyskinesias are well described with phenytoin but have only occasionally been reported with carbamazepine. We present two patients with carbamazepine-induced dyskinesia, one with ocular skew deviation and down-beating nystagmus associated with a high therapeutic level, and another with systemic dyskinesia with a toxic carbamazepine level, and compare these with previously reported cases.
