1. What is Montelukast Alter and what is it used for
What is Montelukast Alter
Montelukast is a leukotriene receptor antagonist that blocks substances called leukotrienes.
How it worksMontelukast Alter
Leukotrienes cause narrowing and swelling of the airways in the lungs. By blocking leukotrienes, montelukast 4 mg improves asthma symptoms and helps control asthma.
When to useMontelukast Alter
Your doctor has prescribed montelukast 4 mg to treat your child's asthma and prevent asthma symptoms during the day and night.
- Montelukast is used to treat patients between 2 and 5 years of age who are not adequately controlled with their medication and need additional treatment.
- Montelukast is also used as an alternative treatment to inhaled corticosteroids in patients between 2 and 5 years of age 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 narrowing of the airways caused by exercise in patients 2 years of age and older.
Depending on your child's symptoms and the severity of their asthma, your doctor will determine how to use montelukast.
What is asthma?
Asthma is a chronic disease.
Asthma includes:
- difficulty breathing due to narrowing of the airways. This narrowing of the airways worsens and improves in response to various diseases.
- airways that are sensitive and react to many things, such as cigarette smoke, pollen, cold air, or exercise.
- swelling (inflammation) of the inner layer of the airways.
Asthma symptoms include: coughing, wheezing, and chest congestion.
