1. What Montelukast is and what it is used for
Montelukast is a leukotriene receptor antagonist that blocks substances called leukotrienes. Leukotrienes cause narrowing and swelling of airways in the lungs. By blocking leukotrienes, Montelukast improves asthma symptoms and helps control asthma.
Your doctor has prescribed Montelukast to treat you or your child’s asthma, preventing asthma symptoms during the day and night.
• Montelukast is used for the treatment of patients who are not adequately controlled on their medication and need additional therapy.
• Montelukast may also be used as an alternative treatment to inhaled corticosteroids for 6 to 14 year old patients who have not recently taken oral corticosteroids for their asthma and have shown that they are unable to use inhaled corticosteroids.
• Montelukast also helps prevent the narrowing of airways triggered by exercise.
Your doctor will determine how Montelukast should be used depending on the symptoms and severity of your or your child's asthma.
What is asthma?
Asthma is a long-term disease.
Asthma includes:
• difficulty breathing because of narrowed airways. This narrowing of airways worsens and improves in response to various conditions.
• sensitive airways that react to many things, such as cigarette smoke, pollen, cold air, or exercise.
• swelling (inflammation) in the lining of the airways.
Symptoms of asthma include: Coughing, wheezing, and chest tightness.
