1. What Montelukast 4 mg Chewable Tablet is and what it is used for
Montelukast 4 mg Chewable Tablet contains montelukast, which is a leukotriene receptor antagonist that blocks substances called leukotrienes.
Leukotrienes cause narrowing and swelling of airways in your lungs. By blocking leukotrienes, Montelukast 4 mg Chewable Tablet improves asthma symptoms and helps control asthma.
Your doctor has prescribed Montelukast 4 mg Chewable Tablets to treat your child's asthma, preventing asthma symptoms during the day and night.
• Montelukast 4 mg Chewable Tablet 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 Chewable Tablet 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 Chewable Tablet also helps prevent the narrowing of airways triggered by exercise for patients 2 years of age and older.
Your doctor will determine how Montelukast 4 mg Chewable Tablets should be used depending on the symptoms and severity of your child's asthma.
