1. What is Singulair 10 and what is it used for
What is Singulair 10
Singulair 10 is a leukotriene receptor antagonist, which blocks the action of substances called leukotrienes.
How Singulair 10 works
Leukotrienes cause the airways to narrow and swell, and also cause allergy symptoms. By blocking the action of leukotrienes, Singulair 10 relieves asthma symptoms, helps control asthma, and relieves symptoms of seasonal allergies (also known as hay fever or seasonal allergic rhinitis).
When to use Singulair 10
Your doctor has prescribed Singulair 10 for the treatment of asthma, to prevent asthma symptoms from occurring during the day and at night.
- Singulair 10 is used in the treatment of adult and adolescent patients 15 years and older who have not achieved adequate control of asthma with their current medications and require additional treatment.
- Singulair 10 also helps prevent narrowing of the airways caused by exercise.
- In patients with asthma, Singulair 10 may also relieve symptoms of seasonal allergic rhinitis.
Your doctor will determine how to take Singulair 10, depending on the symptoms and severity of asthma.
What is asthma?
Asthma is a chronic disease. In asthma, there are:
- breathing difficulties caused by narrowing of the airways. This narrowing worsens and improves in response to various factors.
- airway hypersensitivity, which reacts 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.
What are seasonal allergies?
Seasonal allergies (also known as hay fever or seasonal allergic rhinitis) are allergic reactions that occur frequently due to airborne pollen from trees, grasses, and weeds. Typical symptoms of seasonal allergies may include: stuffy nose, runny nose; sneezing; tearing, swelling, redness, and itching of the eyes.
