What is this medicine?

MONTEL (Montelukast 10 mg) is a leukotriene receptor antagonist. This medicine is used to prevent and control asthma symptoms such as wheezing and shortness of breath, and to relieve symptoms of seasonal allergies like sneezing, runny nose, and nasal congestion. It works by blocking leukotrienes, substances in the body that cause asthma and allergy symptoms.
