Isoniazid, in therapeutic doses, may produce convulsions which resemble grand mal epilepsy.1 This problem may occur in patients without a previous history of epilepsy. The hazards of isoniazid therapy in epileptics have been reported by Fetterhoff,2 who cited a case of status epilepticus precipitated by
