SINGULAIR works differently to treat allergies.
Although many allergy medicines work by blocking histamine, SINGULAIR works differently to relieve symptoms by blocking leukotrienes, an underlying cause of indoor and outdoor allergy symptoms. Ask your or your child's doctor about prescription SINGULAIR—a different way to treat allergies.
