Drug allergies are defined as any noxious, unintended, and undesired effect of a drug that occurs for prevention, diagnosis, or treatment.
The most common drug allergy is to penicillin.
Drug allergy symptoms range from mild side effects, such as rashes and nausea, to life-threatening anaphylaxis.
UT Southwestern Medical Center’s allergy program offers comprehensive allergen skin testing, pulmonary-function testing, advanced anti-immunoglobulin (IgE) therapy, and drug desensitization therapy for patients who are allergic to medications necessary for their health.
