SINGULAIR (Montelukast) 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 seasonal allergies in adults and children as young as 2 years. Asthma is a chronic lung disease that cannot be cured - but can be controlled. Asthma is characterized by narrowed, inflamed, and sensitive airways. Narrowed airways cause breathing to become difficult. Various conditions, called triggers, may cause airways to narrow. Inflamed airways, where the lining of airways becomes swollen, make breathing difficult. Sensitive airways react to many things, such as cigarette smoke, pollen, and cold air. Symptoms of asthma include coughing, wheezing, and chest tightness, although not all people with asthma wheeze. For some, coughing may be the only symptom of asthma. Symptoms often occur during the night or after exercise. SINGULAIR (Montelukast) should NOT be used for the fast relief of acute asthma attacks or to prevent or treat asthma made worse by exercise. 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 (Montelukast) 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. SINGULAIR (Montelukast) is not a steroid and it's not an inhaler. SINGULAIR (Montelukast) is a different kind of asthma controller. SINGULAIR is a once-a-day treatment that can help control your asthma for a full 24 hours.
