About Montelukast
Montelukast is a medicine used to prevent and manage asthma symptoms over the long term. It also helps relieve seasonal and year-round allergy symptoms, such as sneezing, a stuffy nose, and itchy eyes. Additionally, doctors prescribe this medication to prevent breathing difficulties that occur during exercise.

Patients Concern
Disease/Condition Glossary
Asthma: It is a local inflammatory disease of the lungs & airways associated with exaggerated airway narrowing to certain triggers like viruses, allergens & exercise. Asthma leads to frequent wheezing, breathlessness, chest tightness, and coughing episodes that vary in severity over time. Asthmatic attacks and narrowing of airway passages are brought about by the production & secretion of certain chemicals inside the lungs called leukotrienes. This condition is characterised by wheezing, breathlessness, chest tightness & cough with or without sputum.
Allergy: It is an immune system response to foreign elements, typically not harmful to your body. These foreign elements are known as ‘allergens. ’ Allergic condition varies from person to person. Some might be allergic to certain foods and seasonal allergies like hay fever. While others might be allergic to pollen or pet dander. One of the symptoms of an allergy is a cough. Coughing occurs as a reflex action in the throat when there is mucus or any other foreign irritant in it.
