1. What is Montelukast VIR and what is it used for

Montelukast VIR is a leukotriene receptor antagonist that blocks substances called leukotrienes.

How Montelukast works

Leukotrienes cause the airways in the lungs to narrow and swell, and can also cause allergy symptoms. By blocking the leukotrienes, montelukast improves the symptoms of asthma, helps control asthma, and improves the symptoms of seasonal allergies (also known as hay fever or allergic rhinitis).

When to use Montelukast

Your doctor has prescribed montelukast to treat your asthma and prevent your asthma symptoms during the day and night.

• Montelukast is used for the treatment of adults and adolescents 15 years of age and older who are not adequately controlled with their medication and need additional treatment.
• Montelukast also helps prevent the narrowing of the airways caused by exercise.
• In patients with asthma who are indicated for montelukast for asthma, Montelukast VIR may also provide symptomatic relief of seasonal allergic rhinitis.

Depending on your symptoms and the severity of your asthma, your doctor will determine how you should use Montelukast VIR.

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 lining of the airways.

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

What are seasonal allergies?

Seasonal allergies (also known as hay fever or allergic rhinitis) are an allergic reaction often caused by airborne pollen from trees, grass, and weeds. The symptoms of seasonal allergies typically can include: stuffy nose, runny nose; sneezing; itchy, watery, red, and swollen eyes.
