What this medicine is used for

The name of your medicine is Chemmart Montelukast.
It contains the active ingredient montelukast (as montelukast sodium).
It is used to:
prevent asthma symptoms, including those that occur during the day and at night-time
prevent the narrowing of airways triggered by exercise
seasonal allergic rhinitis (hay fever) symptoms.
Montelukast tablets are not used to treat an acute attack of asthma. If an acute attack occurs, follow your doctor's instructions for your reliever medicine, and keep taking your montelukast tablets each night or as prescribed.
As a preventive medicine for asthma, montelukast can be used alone or in combination with other preventive medicines, such as inhaled corticosteroids. Your doctor may reduce your dose of inhaled corticosteroid while you are taking montelukast.
Asthma is a lung disease and has the following characteristics:
narrowed airways causing breathing to become difficult
inflamed airways, which means the lining of airways become swollen
sensitive airways that react to many things, such as cigarette smoke, pollen, or cold air.
Symptoms of asthma include coughing, wheezing and chest tightness. Not all people with asthma wheeze. For some, coughing may be the only symptom of asthma.
Symptoms often occur during the night or after exercise.
Seasonal allergic rhinitis (also known as hay fever) is an allergic response often caused by airborne pollens from trees, grasses, and weeds. The daytime and night-time symptoms of seasonal allergic rhinitis typically may include: stuffy, runny, itchy nose; sneezing; watery, swollen, red, itchy eyes.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.

How it works

Montelukast belongs to a group of medicines called leukotriene receptor antagonists. It works by blocking substances in your lungs called leukotrienes that cause narrowing and swelling of airways. Blocking leukotrienes improves asthma symptoms and helps prevent asthma attacks. Leukotrienes also cause allergic rhinitis symptoms. By blocking leukotrienes, montelukast improves seasonal allergic rhinitis symptoms.
There is no evidence that this medicine is addictive.

Use in children

Montelukast should not be used in children under 2 years of age.
Safety and effectiveness in children younger than 2 years of age have not been studied.
