1. What Montelukast 4 mg chewable tablets

Montelukast 4 mg chewable tablets are a

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

year old patients who are not adequately
controlled on their medication and need
additional therapy.
 This medicine 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.
 This medicine also helps prevent the narrowing
of airways triggered by exercise for patients 2
years of age and older.
Your doctor will determine how these tablets
should be used depending on the symptoms and
severity of your child's asthma.
