Acute management of hypersensitivity reactions and seizures.
The most crucial step in the management of an antiepileptic drug (AED) hypersensitivity reaction is the recognition of the clinical syndrome and cessation of the presumed offending agent. The severity of the developing reaction will shape the course of treatment because multiple organ systems may become affected. Management of conjunctival involvement and treatment of skin lesions dominate care, with patients whose skin lesions are extensive benefitting from treatment in a structured burn unit. Neutropenia and sepsis are common and potentially fatal complicating factors. The use of steroids remains controversial, as is the utility of immune modulation with other agents such as cyclophosphamide and i.v. immunoglobulin. Acute treatment of seizures should be addressed with i.v. benzodiazepines, given either intermittently or by continuous infusion. Choice of long-term maintenance AEDs should take into consideration the crossreactivity among AEDs that share an arene oxide metabolite.
