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 childʼs asthma, preventing asthma
symptoms during the day and night.
• Montelukast is used for the treatment of
6 months to 5 year old 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 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
• Montelukast 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.
