Singulair is a leukotriene receptor antagonist. It works by blocking a substance called leukotrienes, which help reduce certain types of asthma and allergies.


If you take more dose you need in long period of time it can lead to such symptoms as thirst, drowsiness, dilated pupils, increased muscle movements, or severe stomach pain. If you experience one of them call your doctor immediately.
