Read this information before you start taking
SINGULAIR . Also, read the leaflet you get each time
you refill SINGULAIR, since there may be new information
in the leaflet since the last time you saw it. This leaflet
does not take the place of talking with your doctor
about your medical condition and/or your treatment.
What is SINGULAIR*?
• SINGULAIR is a medicine called a leukotriene
receptor antagonist. It works by blocking
substances in the body called leukotrienes.
Blocking leukotrienes improves asthma and allergic
rhinitis. SINGULAIR is not a steroid. Studies have
shown that SINGULAIR does not affect the growth
rate of children. (See the end of this leaflet for more
information about asthma and allergic rhinitis.)
SINGULAIR is prescribed for the treatment of asthma,
the prevention of exercise-induced asthma, and
allergic rhinitis:
1. Asthma.
SINGULAIR should be used for the long-term
management of asthma in adults and children
ages
12
months and older.
Do not take SINGULAIR for the immediate relief
of an asthma attack. If you get an asthma attack,
you should follow the instructions your doctor
gave you for treating asthma attacks.
2. Prevention of exercise-induced asthma.
SINGULAIR is used for the prevention of exercise-
induced asthma in patients 15 years of age and older.
3. Allergic Rhinitis.
SINGULAIR is used to help control the symptoms
of allergic rhinitis (sneezing, stuffy nose, runny
nose, itching of the nose). SINGULAIR is used to
treat seasonal allergic rhinitis (outdoor allergies
that happen part of the year) in adults and children
ages
2
years and older, and perennial allergic
rhinitis (indoor allergies that happen all year) in
adults and children ages
6
months and older.

These occur usually, but not always, in patients who
were taking steroid pills by mouth for asthma and
those steroids were being slowly lowered or stopped.

this condition, you must tell your doctor right away if
you get one or more of these symptoms:
• a feeling of pins and needles or numbness of
arms or legs
• a flu-like illness
• rash
• severe inflammation (pain and swelling) of the
sinuses (sinusitis)
These are not all the possible side effects of SINGULAIR.
For more information ask your doctor or pharmacist.
