Evaluation and management of pediatric drug allergic reactions.

Drug allergy is a common reason for consulting an allergist. Determining whether a particular drug is involved can be accomplished with a careful history and physical examination, knowledge of the common and idiosyncratic reactions of the drugs in question, and selective skin testing. If a drug reaction is suspected, alternatives exist to allow continued appropriate treatment. A practical approach to the pediatric patient is outlined along with a general discussion of common drug allergic reactions encountered in clinical practice.
