1. What is Montelukast Teva and what is it used for
What is Montelukast Teva
Montelukast Teva, chewable tablets is a leukotriene receptor antagonist, i.e. it blocks the action of substances called leukotrienes.
How Montelukast Teva works
Leukotrienes cause narrowing and swelling of the airways in the lungs. By blocking the action of leukotrienes, Montelukast Teva, chewable tablets relieves asthma symptoms and helps control asthma.
When to use Montelukast Teva
Your doctor has prescribed Montelukast Teva, chewable tablets to treat asthma and prevent asthma symptoms day and night.
- Montelukast Teva, chewable tablets is used to treat children and adolescents aged 6 to 14 years who have not achieved adequate control of asthma with their current medications and require additional treatment.
- Montelukast Teva may also be used instead of inhaled corticosteroids in patients aged 6 to 14 years who have not recently taken oral corticosteroids for asthma and are not able to use inhaled corticosteroids.
- Montelukast Teva also helps prevent narrowing of the airways caused by physical exertion.
Depending on the symptoms and severity of asthma in the patient, the doctor will decide how to use Montelukast Teva.
What is asthma?
Asthma is a chronic disease.
- difficulty breathing due to narrowing of the airways. The narrowing of the airways worsens or improves in response to various factors.
- sensitivity of the airways, which causes them to react to many factors, such as cigarette smoke, plant pollen, cold air, or physical exertion.
- swelling (inflammation) of the lining of the airways.
Asthma symptoms include: coughing, wheezing, and a feeling of pressure in the chest.
