Skin eruption with gabapentin in a patient with repeated AED-induced Stevens-Johnson's syndrome.
Skin eruptions have been reported with the use of all antiepileptic drugs and there is a significant risk of cross-reactivity between these agents in causing serious eruptions such as Stevens-Johnson's syndrome. Gabepentin is usually considered a safe agent for patients with a previous history of drug allergies and there have been no cases of skin eruption reported to the gabapentin post marketing surveillance. We report a patient who had severe Stevens-Johnson's syndrome induced by phenytoin and later by carbamazepine. Subsequent use of gabapentin also resulted in a skin eruption which was limited to the lower extremities but without systemic or mucosal involvement. This case suggests that patients with a strong history of drug-induced idiosyncratic reactions may experience such reactions to gabapentin as well.
