1. What is Singulair Mini and what is it used for

What is Singulair Mini

Singulair Mini is a leukotriene receptor antagonist that blocks the action of substances called leukotrienes.

How Singulair Mini works

Leukotrienes cause narrowing and swelling of the airways. By blocking the action of leukotrienes, Singulair Mini relieves asthma symptoms and helps control asthma.

When to use Singulair Mini

The doctor has prescribed Singulair Mini for the treatment of asthma in a child to prevent asthma symptoms from occurring during the day and at night.

• Singulair Mini is used in the treatment of patients from 6 months to 5 years of age who have not achieved adequate control of asthma with their current medications and require additional treatment.
• Singulair Mini may also be used instead of inhaled corticosteroids in patients from 2 to 5 years of age who have not recently taken oral corticosteroids for asthma and are unable to use inhaled corticosteroids.
• Singulair Mini also helps prevent narrowing of the airways caused by physical exertion in patients 2 years of age and older.

The doctor will determine how to use Singulair Mini based on the child's symptoms and the severity of the asthma.

What is asthma?

Asthma is a chronic disease.

In asthma, there are:

• breathing difficulties caused by narrowing of the airways, which worsens and improves in response to various factors.
• sensitivity of the airways, which react to many factors, such as cigarette smoke, pollen, cold air, or physical exertion.
• swelling (inflammation) of the lining of the airways.

Asthma symptoms include: coughing, wheezing, and a feeling of tightness in the chest.

2. Important information before giving Singulair Mini to a child
