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 your child’s asthma, preventing asthma symptoms during
the day and night.





Montelukast 4 mg is used for the treatment of 2 to 5 year old patients who are not adequately controlled
on their medication and need additional therapy.
Montelukast 4 mg may also be used as an alternative treatment to inhaled corticosteroids for 2 to 5 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 4 mg also helps prevent the narrowing of airways triggered by exercise for patients 2 years
of age and older.

Your doctor will determine how Montelukast should be used depending on the symptoms and severity of
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.
