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.
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.
