What it means

A drug allergy is an immune system reaction to a medication in which your body mistakenly identifies the drug as harmful and mounts a defensive response. Reactions range from mild hives, itching, or skin rash to life-threatening anaphylaxis involving throat swelling, difficulty breathing, and dangerously low blood pressure. A drug allergy differs from a side effect because it involves your immune system and can become more severe with each repeated exposure. Common drug allergies include reactions to penicillin, sulfa antibiotics, aspirin, and certain pain relievers. Always disclose known drug allergies to every healthcare provider and pharmacist before receiving any new medication or procedure.
