1. What is montelukast cinfa and what is it used for

montelukast cinfa is a leukotriene receptor antagonist that blocks substances called leukotrienes.

How does montelukast cinfa work?

Leukotrienes cause narrowing and swelling of the airways in the lungs. By blocking leukotrienes, montelukast improves asthma symptoms and helps control asthma.

When should montelukast cinfa be used?

Your doctor has prescribed montelukast to treat your child's asthma and prevent asthma symptoms during the day and night.

  • Montelukast is used to treat patients between 6 months 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 the treatment of their asthma and have demonstrated 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 cinfa.

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.
