Abstract
Allergic reactions and systemic desensitization to corticosteroids have been documented rarely in English language literature. These reactions appear more often when the agent is applied topically and may lead to dangerous complications in patients if administered i.v. Therefore, the safety and efficacy of using an i.v. corticosteroid for desensitization in a patient who has a history of allergy to corticosteroid must be weighed carefully, especially when the aim of its use is to prevent an allergic reaction from a second drug. We report a case of successful systemic hydrocortisone desensitization in a patient with radiocontrast-induced anaphylactoid reaction and corticosteroid allergy. Sensitization to corticosteroids was determined through skin testing. The patient was desensitized to hydrocortisone and premedicated with hydrocortisone and diphenhydramine and subsequently underwent cardiac catheterization with radiocontrast without adverse reaction.
