Abstract
Drug reaction with eosinophilia and systemic symptoms syndrome is a severe type IV (delayed T-cell-dependent reaction) hypersensitivity reaction, characterized by fever, mucocutaneous eruptions, eosinophilia, and systemic inflammatory involvement. It usually begins a few weeks after the exposure to offending drug. Commonly implicated drugs are aromatic anticonvulsants (phenytoin, phenobarbitone, and carbamazepine) and sulfa drugs (sulfonamides, sulfasalazine, and dapsone). It is a potentially life-threatening hypersensitivity reaction. Here we report a case of drug reaction with eosinophilia and systemic symptoms syndrome associated with carbamazepine, which was successfully treated with intravenous methylprednisolone.
