1. What is Montelukast UR 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 and can also cause allergy symptoms. By blocking leukotrienes, Montelukast UR improves asthma symptoms, helps control asthma, and improves symptoms of seasonal allergies (also known as hay fever or seasonal allergic rhinitis).

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

  • Montelukast UR is used for the treatment of patients who are not adequately controlled with their medication and need additional treatment.
  • Montelukast UR also helps prevent narrowing of the airways caused by exercise.
  • In asthmatic patients with Montelukast UR indicated for the treatment of asthma, Montelukast UR 10 mg may also provide relief from symptoms of seasonal allergic rhinitis.

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

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. Asthma symptoms include: Coughing, wheezing, and chest congestion.

What are seasonal allergies?

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