چکیده
Betalactams are the most frequent cause of hypersensitivity reactions to drugs mediated by a specific immune mechanism. Immediate occur within 1 6 hours after betalactam administration, and generally IgE-mediated. They clinically translate into urticaria, angioedema anaphylaxis. Non-immediate or delayed hour administration. These common usually T cells. The type is maculopapular morbilliform exanthematous eruption. Most individuals who report allergies penicillin betalactams can tolerate this group antibiotics. To make diagnosis, detailed medical history essential verify whether it was an immediate non-immediate reaction. Thereafter, in vivo and/or vitro tests for investigation may be performed. challenging test considered gold standard method diagnosis hypersensitivity. first approach when suspecting reaction discontinue exposure drug, only treatment desensitization, which has very precise indications. misdiagnosis allergy affects health system, since label associated with increased bacterial resistance, higher rate therapeutic failure, prolonged hospitalizations, readmissions, costs. Thus, develop strategies assist prescription antibiotics patients identified at hospitals, enhance education their caregivers, as well non-specialist physicians.
