1. What is Monkasta and what is it used for

What is Monkasta

Monkasta 10 mg is a leukotriene receptor antagonist that blocks substances called leukotrienes.

How Monkasta works

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

When should Monkasta be used

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

  • Monkasta is used for the treatment of adults and adolescents 15 years and older who are not adequately controlled with their medication and need additional treatment.
  • Monkasta also helps prevent narrowing of the airways caused by exercise.
  • In patients with asthma where Monkasta is indicated for asthma, Monkasta 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 Monkasta.

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: Cough, wheezing, and congestion in the chest.

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, swollen, red, and stinging eyes.

  • Any patient being treated with asthma medications should 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.
  • Do not take acetylsalicylic acid (aspirin) or anti-inflammatory medications (also known as non-steroidal anti-inflammatory drugs or NSAIDs) if they make your asthma worse.
