What symptoms indicate someone might be having an allergic reaction?
Updated: 11-Apr-2025

Allergic reaction symptoms vary based on the trigger but often include sneezing, runny nose, itchy eyes, skin rashes, or swelling. Food or medication allergies may cause hives, abdominal pain, or nausea. Severe reactions, like anaphylaxis, involve difficulty breathing, throat swelling, rapid heartbeat, and drop in blood pressure.

Anaphylaxis is a medical emergency requiring immediate epinephrine injection and hospital care. Identifying and avoiding allergens is the best prevention. Antihistamines and corticosteroids help with mild symptoms. Allergy testing can identify specific triggers. Always inform doctors about known allergies before treatment or procedures.
