1. What MONTELUKAST TARBIS 4 mg is and what it is used for

MONTELUKAST TARBIS 4 mg 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 TARBIS 4 mg improves asthma symptoms and helps control asthma.

Your doctor has prescribed MONTELUKAST TARBIS 4 mg to treat your child's asthma and prevent asthma symptoms during the day and night.

MONTELUKAST TARBIS 4 mg 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 TARBIS 4 mg 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 unable to use inhaled corticosteroids.
MONTELUKAST TARBIS 4 mg 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, your doctor will determine how to use MONTELUKAST TARBIS 4 mg.
