Allergy Overview

A child with allergies is sensitive to certain substances called allergens. Allergens are tiny particles (such as pollen and mold spores) that are carried in the air and bring on allergy symptoms in some people. Allergens are normally harmless to a child without allergies. But for children with allergies, it is a different story. If your child is sensitive to a particular allergen, exposure to it can trigger an allergic response. (That is why allergens are also known as triggers.)

SINGULAIR® (montelukast sodium) is a prescription medicine approved to help control asthma in adults and children as young as 12 months and to help relieve the symptoms of indoor and outdoor allergies (outdoor allergies in adults and children as young as 2 years, and indoor allergies in adults and children as young as 6 months).

IMPORTANT SAFETY INFORMATION

SINGULAIR should be taken once a day, as prescribed. SINGULAIR is available by prescription only.

Side effects are generally mild and vary by age, and may include headache, ear infection, sore throat, and upper respiratory infection. Side effects generally did not stop patients from taking SINGULAIR. SINGULAIR should not be taken by people who are sensitive to any of its ingredients.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
