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

Montelukast Sandoz 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 improves asthma symptoms and helps control asthma.

Your doctor has prescribed montelukast for your child to treat asthma, preventing asthma symptoms during the day and night.

• Montelukast Sandoz is used for the treatment of patients between 2 and 5 years of age who are not adequately controlled with their medication and need additional treatment.
• Montelukast Sandoz 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 not able to use inhaled corticosteroids.

Montelukast Sandoz also helps prevent narrowing of the airways caused by exercise in patients 2 years of age and older.

• Montelukast Sandoz 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, their doctor will determine how to use montelukast.
