Drug allergies, also termed adverse drug reactions (ADRs), are a problem for individuals of all ages, from paediatric to geriatric, and in all medical settings. They may be a predictable reaction to a specific drug (termed Type A) or particular to the individual (termed Type B). Health professionals, especially those caring for patients at the point of entry into the medical system, have a very important role in determining if and when a patient is having an ADR. The purpose of this article is to review the pathophysiology of ADRs, describe the signs and symptoms of different classifications of ADRs, and present the medical and wound treatment for patients with systemic and cutaneous reactions to drug allergies.
