Allergic reactions range from localized hives and itching to systemic anaphylaxis with airway swelling, wheeze, hypotension, and GI symptoms. Common triggers include foods, medications, insect stings, latex, and exercise. Mild reactions often respond to a non-sedating oral antihistamine and removal of the trigger. Anaphylaxis is a medical emergency: intramuscular epinephrine is first-line and should not be delayed for antihistamines or steroids. Anyone with a history of anaphylaxis should carry two epinephrine auto-injectors and have an action plan.
