DISCOVER HOW SINGULAIR WORKS

Do allergy symptoms keep you from doing what you want to do? Once-a-day SINGULAIR is proven to help relieve indoor and outdoor allergy symptoms. So if allergies are bothering you, it may be time to try a different way to help relieve allergy symptoms.

Although many allergy medicines block histamine, SINGULAIR is an indoor and outdoor allergy medicine that blocks leukotrienes (loo-ko-TRY-eens), an underlying cause of allergy symptoms.

How SINGULAIR helps relieve indoor and outdoor allergy symptoms

Triggers

What happens?

When you breathe in allergens, such as pollen, mold spores, pet dander, or dust, you trigger a chain of events in your body.

Your body's response

In response, your body makes chemicals, including histamine, leukotrienes, and others.

These chemicals cause sneezing and an itchy, stuffy, runny nose.

Many allergy medicines work by blocking histamine.

How SINGULAIR works
