Sensitization to corticosteroids can occur through many routes such as nasal, aerosol, parenteral, oral and topical. Delayed allergic reactions may be observed after topically applied glucocorticoids, but IgE-mediated type 1 (immediate) allergic reactions, which occur after systemic application of glucocorticoids, are very rare. When case-based publications were examined, it was noticed that corticosteroid-associated IgE-mediated type 1 hypersensitivity reactions were more common in patients with nonsteroidal anti-inflammatory drug-exacerbated respiratory diseases (NERD). We present a 32-year-old patient with nonsteroidal anti-inflammatory drug-exacerbated airway disease and a hypersensitivity reaction due to methylprednisolone.enIntravenous hydrocortisoneCellsCorticosteroidsDiagnosisMethylprednisoloneHypersensitivityDrug allergyCorticosteroidsSamter's triad (nonsteroidal anti-inflammatory drug-exacerbated respiratory disease)Science & technologyLife sciences & biomedicineAllergyArticle00048041370000911111417210.21911/aai.346
