[Corticosteroid allergy: a paradox?]

Although corticosteroids have both antiinflammatory and immunosuppressive effects, they can occasionally induce allergic reactions when given topically or systemically. Since cross-reactions exist within the corticosteroid groups A-D, the corticosteroid should be changed to another group whenever suspicion arises. It makes sense to render an allergy-related diagnosis early so that a suitable corticosteroid is ready for an emergency.
