What is an allergic reaction?

An allergic reaction is an overreaction of your immune system to allergens, which releases chemicals such as histamines into your system. The release creates symptoms like a runny nose, watery eyes, sneezing or itchy skin as allergens are driven from your body.

Allergic reactions can happen anywhere, anytime.

In severe cases, histamines can cause anaphylaxis, a reaction that may cause dizziness, shortness of breath or difficulty breathing, a swollen throat or tongue or severe anxiety. If any of these symptoms occur, call 911 or go to your nearest emergency room.
