1. What is Montelukast Pensa and what is it used for

Montelukast Pensa is a leukotriene receptor antagonist that blocks substances called leukotrienes. Leukotrienes cause narrowing and swelling of the airways in the lungs. By blocking leukotrienes, Montelukast Pensa improves asthma symptoms and helps control asthma.

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

  • Montelukast Pensa is used for treatment in patients between 2 and 5 years of age who are not adequately controlled with their medication and need additional treatment.
  • Montelukast Pensa 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 shown that they are unable to use inhaled corticosteroids.
  • Montelukast Pensa also helps prevent exercise-induced narrowing of the airways in patients 2 years of age and older.

Depending on your child's symptoms and the severity of their asthma, your child's doctor will determine how to use Montelukast Pensa.

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.
