You breathe in an asthma trigger, such as pollen from trees or weeds.
Your body releases leukotrienes (loo-ko-TRY-eens) and other chemicals.
These chemicals cause the airways in the lungs to become swollen and red. Muscles around the airways also tighten. This causes asthma symptoms, such as shortness of breath, coughing, and wheezing.
Breathing with swollen airways is like trying to breathe through a narrow straw.
SINGULAIR blocks the action of leukotrienes.
By blocking leukotrienes, SINGULAIR can help prevent asthma symptoms.
SINGULAIR is also an effective treatment for indoor and outdoor allergy symptoms because leukotrienes play an important role in allergy symptoms.
Please see important safety information about SINGULAIR below as well as in the Patient Product Information.
SINGULAIR 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 will NOT replace fast-acting inhalers for sudden symptoms. You should still have rescue medication available and continue to take your other asthma medications unless your doctor tells you to stop. For asthma, SINGULAIR should be taken once a day, in the evening as prescribed, whether or not you have asthma symptoms. If your symptoms get worse or you need to increase the use of your rescue inhaler, call your doctor at once.
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. Check with your doctor if you're pregnant or nursing. SINGULAIR should be taken once a day, as prescribed. SINGULAIR is available by prescription only.
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.
