ALLERGIC type 1 (anaphylactic) reactions to corticosteroid compounds are rare, but a few well-documented case reports of allergic reactions to prednisolone1 and methylprednisolone sodium succinate1 have been reported. We describe a patient who experienced an anaphylactic reaction to systemically administered methylprednisolone. Allergic sensitivity to this compound as well as to hydrocortisone hemisuccinate was documented by results of intradermal and skin prick testing. Furthermore, our patient demonstrated his allergic reaction only to the succinate esters of the parent corticosteroids. This is the first reported case, to our knowledge, of an anaphylactic reaction to only the succinate acid ester of methylprednisolone without reaction to methylprednisolone acetate.
