Corticosteroid allergy
Corticosteroid allergy: A delayed allergic reaction to corticosteroid (drugs similar to cortisone). This occurs in 1-4% of people who use corticosteroids for asthma or other allergic diseases. A positive patch test to a corticosteroid means the patient cannot use that particular steroid.
