Antiepileptic drugs toxicity: A case of toxic epidermal necrolysis in patient with phenytoin prophylaxis post-cranial radiation for brain metastases

摘要

BackgroundTreatment of epilepsy with antiepileptic drugs (AED) is effective and remains the principal mode of management. A group of adverse effects and drug toxicity can develop immediately or later in the course of treatment. AEDs also have the potential of precipitating idiosyncratic adverse effects including serious cutaneous, hematological and hepatic events. Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but severe cutaneous adverse reactions are related to or caused by a variety of medications including AEDs, they carry a high mortality and morbidity rate, accurate diagnosis and rapid treatment may improve the prognosis.
