When your immune system identifies allergens in the body, it releases histamines to combat them which cause your hay fever symptoms like sneezing, runny nose, and itchy watery eyes or throat. Allegra blocks histamine and relieves symptoms, so you can get back to living your life.

Allergy symptoms can be caused by a number of different indoor or outdoor allergens including pollen, ragweed, dust mites, and pet dander. There are things you can do to help alleviate exposure to allergens around your home. Wash your bedding weekly in hot water and dry it in a hot dryer. Vaccum frequently or replace your carpets with hardwood flooring, tile or linoleum. Keep humidity low by using a dehumidifier. Before getting a pet, ask your allergist to determine if you are allergic to animals.

What causes "a-choos": Histamine is a chemical that’s like a warrior living inside your body. When pollen comes in, histamine tries to push it out by making you sneeze, giving you itchy, watery eyes, or making your nose run.

Pollen season—every allergy sufferer’s worst nightmare. Why? When you experience allergies, pollen can irritate your nose, causing more mucus and sneezing than normal. To help reduce symptoms, monitor pollen counts so you can limit your exposure on days when the counts are high.
