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

Montelukast Viatris contains montelukast, which is a leukotriene receptor antagonist that blocks substances called leukotrienes. Leukotrienes cause the airways to narrow and swell, and can also cause allergy symptoms. By blocking the leukotrienes, Montelukast Viatris improves asthma symptoms, helps control asthma, and improves symptoms of seasonal allergies (also known as hay fever or allergic rhinitis).

Your doctor has prescribed Montelukast Viatris to treat asthma and prevent asthma symptoms during the day and night.

• Montelukast Viatris 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 Viatris also helps prevent narrowing of the airways caused by exercise.
• In patients with asthma who are indicated for Montelukast Viatris for asthma, it 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 Viatris.

Montelukast Viatris 10 mg film-coated tablets are used in adults and adolescents 15 years of age and older.

What is Asthma?

Asthma is a chronic disease.

Asthma includes:

• Difficulty breathing due to narrowing of the airways. This narrowing of the airways gets worse and better in response to various diseases.
• Airways that are sensitive and react 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: 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. Symptoms of seasonal allergies typically include: stuffy nose, runny nose; sneezing; itchy, watery, red, and swollen eyes.
