1. 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 your lungs. By blocking leukotrienes, Montelukast improves asthma symptoms and helps control asthma.
Your doctor has prescribed this medicine to treat asthma, preventing your asthma symptoms during the day and night.
• This medicine is used for the treatment of 6 to 14 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 6 to 14 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.
Your doctor will determine how this medicine should be used depending on the symptoms and severity of your child's asthma.
What is asthma?
Asthma is a long-term disease
Asthma includes:
• Difficulty breathing because of narrowed airways. This narrowing of airways worsens and improves in response to various conditions.
• Sensitive airways that react to many things, such as cigarette smoke, pollen, cold air or exercise.
• Swelling (inflammation) in the lining of the airways.
Symptoms of asthma include: Coughing, wheezing and chest tightness.

• If your or your child’s asthma or breathing gets worse, tell your doctor immediately.
• Oral Montelukast is not meant to treat acute asthma attacks. If an attack occurs, follow the instructions your doctor has given you for your
child. Always have your inhaled rescue medicine for asthma attacks with you.

needles or numbness of arms or legs, worsening of pulmonary symptoms, and/or rash, you should consult your doctor.
