Possible precipitation of myoclonic seizures with oxcarbazepine

Oxcarbazepine is an antiepileptic drug widely used to treat partial seizures in children and adults. We report two children who developed mycolonic seizures and had abnormal electroencephalograms when oxcarbazepine was introduced. Although it is possible that the emergence of myoclonic seizures and deterioration of the electroencephalograms were due to the natural course of the disorder, clinicians should be aware of the possible detrimental effects of oxcarbazepine in children with seizures.
