title: Aplastic anemia following therapy for absence seizures with ethosuximide.
abstract: We describe a case of aplastic anemia in an 8-year-old girl which was diagnosed 8 months after initiation of ethosuximide as treatment for absence seizures. Blood counts had been previously monitored and were normal. The patient successfully underwent allogeneic bone marrow transplantation. Only 8 cases of ethosuximide-associated aplastic anemia have been reported, and in only one of these reports, was ethosuximide used as a single antiepileptic agent. This rare, but potentially fatal complication of ethosuximide raises the question of whether routine monitoring of blood counts during ethosuximide therapy is useful and should be undertaken.
