Brand name: Singulair
Pronounced: sing-you-LAIR
Generic name: Montelukast sodium
Why is Singulair prescribed?
Singulair is used for long-term prevention of asthma. It reduces the
swelling and inflammation that tend to close up the airways, and relaxes
the walls of the bronchial tubes, expanding the airways and permitting
more air to pass through.
Singulair is also used to relieve the stuffy, runny nose and sneezing
caused by seasonal allergies.
Most important fact about Singulair
Singulair alleviates the on-going symptoms of asthma, but it won't
stop an acute asthma attack. For that you need a fast-acting, orally
inhaled airway opener such as Alupent or Proventil.
How should you take Singulair?
Take a Singulair tablet once daily, whether or not you have any symptoms.
The tablet can be taken with or without food.
If you have asthma, or asthma plus allergies, take Singulair in the
evening. If you have only allergies, you can take Singulair at any
time.
The oral granules should be given directly in the child's mouth. The
granules can also be mixed with a spoonful of one of the following
soft foods: applesauce, carrots, rice, or ice cream. The food should
be cold or at room temperature.
The granules should not be dissolved in liquids before giving them
to your child. However, the child can drink liquids after the granules
have been swallowed. Do not open the granules packet until your child
is ready to take them. Once the packet is opened, the full dose of
medication must be given within 15 minutes. Throw away any unused portion
of the granules; do not store them for future use.
If you miss a dose...
Take it as soon as you remember. If it is almost time for your next
dose, skip the one you missed and go back to your regular schedule.
Do not take 2 doses at once.
Storage instructions...
Store at room temperature, away from moisture and light.

Special warnings about Singulair
After you begin taking Singulair, your doctor may be able to slowly
reduce the dosage of other asthma medications such as inhaled steroids.
However, Singulair is not a complete replacement for such drugs, so
you should not abruptly stop using them unless your doctor recommends
it. If your asthma symptoms get worse or you develop a rash, numbness,
or heart problems as you reduce your dose of steroids, check with your
doctor. Such reactions usually result from a reduction in oral steroid
therapy.
If your asthma gets worse after exercise, you'll need to continue
using a short-acting inhaled airway opener to prevent the problem and
relieve attacks.
If you are allergic to aspirin and other nonsteroidal anti-inflammatory
drugs (NSAIDs), you should continue to avoid them. Singulair does not
remedy this problem.
If you have difficulty breathing while taking Singulair, or find that
you need your orally inhaled bronchodilator more often than usual (or
require more puffs than prescribed), notify your doctor.
If you have a child with phenylketonuria--an inability to process
phenylalanine that quickly leads to mental retardation--you should
be aware that Singulair chewable tablets contains this substance.
Possible food and drug interactions when
taking Singulair
If Singulair is taken with certain other drugs, the effects of either
could be increased, decreased, or altered. It is especially important
to check with your doctor before combining Singulair with the following:
Phenobarbital
Rifampin (Rifadin, Rifamate, Rimactane)
Special information if you are pregnant or breastfeeding
Singulair should be used during pregnancy only if clearly needed.
If you are pregnant or plan to become pregnant, inform your doctor
immediately.
It is not known whether Singulair appears in breast milk. Because
many drugs do make their way into breast milk, use Singulair with caution
if you are breastfeeding.

Little is known about the effects of Singulair overdose. However,
