About company

In people with allergies, the immune system mistakes a substance that’s ordinarily harmless to most people (substances from pollen, mold, pet dander and dust mites) for something dangerous and attacks it. These normally harmless substances are called allergens
Allergen
A substance that your body perceives as foreign and harmful; initiates the 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.
Reducing Your Exposure to Airborne Allergens
In addition to taking Claritin® to help tackle tough symptoms, it’s important to help reduce your exposure to allergy triggers in the first place. You can find simple tips for helping to reduce your exposure to the different indoor and outdoor allergy triggers below.

Outdoor Seasonal Allergies
Outdoor allergies are often called seasonal allergies because they change with the seasons. They’re caused by an overreaction of the immune system to ordinarily harmless allergens found outside, such as those from mold spores and tree, grass and weed pollens. While these allergens can be difficult to avoid, you can find easy tips to help minimize your exposure so you can enjoy more of the great outdoors.
