What MONTELUKAST SANDOZ is used for
MONTELUKAST SANDOZ is used to prevent asthma symptoms, including those that occur during the day and at night-time. It also prevents the narrowing of airways triggered by exercise.
If you have seasonal allergic rhinitis (hay fever), MONTELUKAST SANDOZ also treats your allergic rhinitis symptoms.
It can be used in children 2 years of age and older, teenagers and adults.
MONTELUKAST SANDOZ is 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 SANDOZ each night or as prescribed.
As a preventive medicine for asthma, MONTELUKAST SANDOZ 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 SANDOZ.
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.
For further information about asthma, contact the Asthma Foundation in your state on 1800 645 130, or www.asthmaaustralia.org.au.
Seasonal allergic rhinitis (also known as hay fever) is an allergic response often caused by airborne pollens from trees, grasses, and weeds. The day-time and night-time symptoms of seasonal allergic rhinitis typically may include: stuffy, runny, itchy nose; sneezing; watery, swollen, red, itchy eyes.
How MONTELUKAST SANDOZ 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.
Your doctor may have prescribed MONTELUKAST SANDOZ for another reason. Ask your doctor if you have any questions about why MONTELUKAST SANDOZ has been prescribed for you.
Montelukast is not addictive.
