What LUKAIR is used for
LUKAIR 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), LUKAIR also treats your allergic rhinitis symptoms.
It can be used in children 2 years of age and older, teenagers and adults.
LUKAIR 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 LUKAIR each night or as prescribed.
As a preventive medicine for asthma, LUKAIR 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 LUKAIR.
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 daytime and nighttime symptoms of seasonal allergic rhinitis typically may include: stuffy, runny,
itchy nose; sneezing; watery, swollen, red, itchy eyes.
How LUKAIR works
LUKAIR 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, LUKAIR improves seasonal
allergic rhinitis symptoms.
Your doctor may have prescribed LUKAIR for another reason. Ask your doctor if you have any questions about why LUKAIR has
been prescribed for you.
LUKAIR is not addictive.
