This medication can help decrease the number of times you need to use your quick relief inhaler.Montelukast is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose).

It does not work right away and should not be used to relieve sudden asthma attacks or breathing problems. If an asthma attack or sudden shortness of breath occurs, use your quick-relief inhaler as prescribed.This drug works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies.
