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).
