1. What is Montelukast Bluefish Pharma and what is it used for

What is Montelukast Bluefish Pharma

Montelukast Bluefish Pharma is a leukotriene receptor antagonist that blocks substances called leukotrienes.

How Montelukast Bluefish Pharma works

Leukotrienes cause narrowing and swelling of the airways in the lungs, as well as symptoms of allergy. By blocking the action of leukotrienes, Montelukast Bluefish Pharma alleviates symptoms of asthma, helps control asthma, and alleviates symptoms of seasonal allergies (also known as hay fever or seasonal allergic rhinitis).

When to use Montelukast Bluefish Pharma

The doctor has prescribed Montelukast Bluefish Pharma to treat asthma in a child and prevent asthma symptoms during the day and night. Montelukast Bluefish Pharma is used in children aged 2 to 5 years (4 mg dose) who have not achieved adequate asthma control with their current treatment and require additional treatment. Montelukast Bluefish Pharma may also be used instead of inhaled corticosteroids in children aged 2 to 5 years who have not recently taken oral corticosteroids for asthma treatment and are unable to use inhaled corticosteroids. Montelukast Bluefish Pharma also helps prevent bronchospasm caused by physical exertion in children aged 2 years and older. The doctor will determine how to use Montelukast Bluefish Pharma based on the child's symptoms and the severity of asthma.

What is asthma?

Asthma is a chronic disease. In asthma, there are:

  • Difficulty breathing due to narrowing of the airways. This narrowing of the airways worsens and improves in response to various factors.
  • Sensitivity of the airways, which react to many factors, such as cigarette smoke, pollen, cold air, or physical exertion.
  • Inflammation (swelling) of the lining of the airways.

Asthma symptoms include: coughing, wheezing, and chest tightness.

What are seasonal allergies?

Seasonal allergies (also known as hay fever or seasonal allergic rhinitis) are an allergic response of the body, often caused by airborne pollen from trees, grasses, and weeds. Seasonal allergy symptoms usually include: feeling of nasal congestion, runny nose, and itching of the nose, sneezing, tearing, swelling of the eyelids, redness, and itching of the eyes.

2. Important information before taking Montelukast Bluefish Pharma
