Abstract
A case of severe allergy induced by cefaclor is presented in this article. A 61-year-old man with the perimaxillary inflammation was referred to our department by his family dentist on August 13, 2001. The pathogenic tooth was extracted on August 23, because the inflammation had disappeared with administering the antibiotics in about one week. The patient was given one 250mg capsule of cefaclor for evading the postoperative infection. General weakness and urticaria appeared within about two hours. When he revisited the our hospital three hours after taking the drug, the state of the middle degree shock to be accompanied by the blood pressure decrease and bradycardia was admitted. Epinephrine, hydrocortisone and lactate Ringer's solution were admin-istered immediately, and the state of general condition has been improved successfully. He was discharged 6 days later. Drug-induced lymphocyte stimulation test (DLST) showed the positive for cefaclor.
