What is Singulair (Montelukast) used for?

Singulair (Montelukast)is a leukotriene receptor antagonist used to prevent exercise-induced asthma as well as treat long-term asthma. Compared to some inhalers, this medication takes longer to work, making it not suitable for sudden asthma attacks. Asthma that is hard to control usually needs a rescue inhaler in addition to long term treatments. Essentially, singulair (Montelukast) prevents the body from producing leukotrienes by blocking their receptors. Asthma and allergy symptoms can be caused by leukotrienes, which can cause inflammation and swelling. When you suffer from asthma or allergies, Singulair (Montelukast) blocks leukotrienes.
