Within one week: If you don't feel improvement within 2 weeks then it won't help you.

Difficult to answer: Unlike rescue inhalers which work very quickly, oral drugs like singulair (montelukast) do take awhile. It would not be a very good substitute for a rescue inhaler because of this. Continue your other medications while taking singulair (montelukast) and don't be discouraged. Good Luck

2: Singulair (montelukast) can be effective in as few as 2 hours. For patients with exercise induced asthma should take singulair (montelukast) at least 2 hours before exercise to be able to feel the effect of the medication. Because of the inflammatory nature of asthma in most other cases it can take several days to achieve full benefit of the singulair (montelukast).

Yes: Montelukast is effective as a "controller" medication in mild asthma and also is approved by the fda for allergic rhinitis (hay fever). It may be used alone or with other allergy/asthma medications. All ashtmatics should have a "reliever inhaler" in addition to their controller medication.

Discuss with Ur Dr: Any medication strong enough to do some good may have side effects or do harm.To fine tune therapy you need the person who took a history & did an exam to know the side effects u are dealing with & to offer alternate solutions based on your kids unique findings.This med is rx for both asthma and allergy issues, there are a variety of rx available but all have pros & cons. I know of no perfect meds.
A member asked:

Any side effects to taking singulair (montelukast) off-label for chronic headaches?

1 doctor answer2 doctors weighed in
Dr. Geoffrey Rutledge
Internal Medicine 41 years experience
Not an indication: Singulair (montelukast, now also available in a generic form) is a medicine for treating asthma and chronic allergy syndromes (including severe hay fever). It is not indicated for the treatment of chronic headaches, unless those headaches are part of a persistent allergy syndrome. In fact, one of it's common side effects is headache.

Anti-inflammatory: It is an oral medicine. It belongs to a class of medications known as leukotriene receptor blockers. Leukotrienes are chemicals produced by white blood cells that cause inflammation and cause changes in the airway that lead to asthma. Blocking the leukotriene receptor is a very useful and effective way of controlling asthma. It is also useful in some forms of cough

Singulair is also approved for the treatment of allergic rhinitis in children. The effectiveness is similar to that of antihistamines.
