1. What is MONTELUKAST ASTHMAPHARMA and what is it used for

Montelukast 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 to treat your child's asthma and prevent asthma symptoms during the day and night.

Montelukast is used to treat patients between 2 and 5 years of age who are not adequately controlled with their medication and need additional treatment.

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

Depending on the symptoms and severity of your child's asthma, your doctor will determine how to use Montelukast.

What is asthma?

Asthma is a chronic disease.

Asthma includes:

Difficulty breathing due to narrowing of the airways. This narrowing of the airways worsens and improves in response to various diseases.

Airways that are sensitive to many things, such as cigarette smoke, pollen, cold air, or exercise.

Swelling (inflammation) of the inner layer of the airways.

The symptoms of asthma include: Cough, wheezing, and chest congestion.

2. Before taking MONTELUKAST ASTHMAPHARMA

Tell your doctor about any allergy or medical problem your child has now or has had.

They are allergic (hypersensitive) to montelukast or any of the other components of Montelukast (see section 6).

Be careful with MONTELUKAST ASTHMAPHARMA

If your child's asthma or breathing worsens, tell your doctor immediately.

Oral Montelukast is not indicated for the treatment of acute asthma attacks. If an attack occurs, follow the instructions your doctor has given your child. Always have your child's rescue inhaler medication for asthma attacks.

It is important that your child uses all the asthma medications prescribed by their doctor.

Montelukast should not be used instead of other asthma medications prescribed by your doctor for your child.

If your child is being treated with asthma medications, be aware that if they develop a combination of symptoms such as flu-like illness, tingling or numbness of arms or legs, worsening of lung symptoms, and/or skin rash, they should consult their doctor.

Your child should not take acetylsalicylic acid (aspirin) or anti-inflammatory medications (also known as non-steroidal anti-inflammatory medications or NSAIDs) if they worsen their asthma.

Several neuropsychiatric events (such as changes in behavior and mood, depression, and suicidal tendencies) have been reported in patients of all ages (see section 4). If these symptoms develop while taking Montelukast, contact your doctor.
