200+ Allergens

From your beautiful garden to your furry friends, there are over 200 different airborne allergens out there that can cause allergies to flare up. Learn more about these triggers and find out how Claritin® allergy products can help relieve your symptoms.

What Are Airborne Allergies?

The 200+ different airborne allergens come from four categories, including animals, mold, dust mites, and the pollen from grass, trees, weeds and flowers.

These sources of airborne allergens are light so they can travel through the air and stick to your clothes and hair. In fact, ragweed pollen has been found as far as 400 miles out to sea and two miles up in the atmosphere.1 And one study showed the most common cat allergen was detected in 100 percent of airplane seats tested.2

Claritin® Provides 24-Hour Relief of Symptoms That Can Be Triggered by These Allergens

To understand how Claritin® provides 24-hour, non-drowsy relief from tough allergy symptoms, it’s important to know what causes an allergic reaction.

When you take a breath or rub your nose or eyes, allergens enter your body and your immune system triggers a hypersensitivity reaction. To get rid of the substance it thinks is harmful, your body undergoes various reactions and releases inflammatory mediators like histamine.

When the histamine binds to receptors on other cells in your body, it causes you to experience allergy symptoms, including runny nose, sneezing, itchy/watery eyes, itchy nose or throat, nasal congestion and sinus pressure.

How Claritin® Works

Claritin® is an antihistamine so it hinders the cascade triggered by allergens. By hindering this cascade, Claritin® relieves allergy symptoms that can be caused by 200+ different airborne allergens.

When to Take Claritin®

Follow label indications. Claritin® should be taken when you experience allergy symptoms like sneezing, running nose or itchy, watery eyes.
