Montelukast is prescribed to prevent asthma symptoms (like coughing, wheezing, or difficulty breathing) in adults and children. It is also prescribed to prevent bronchospasm symptoms (difficulty breathing) after exercise (known as exercise-induced bronchospasm).
In addition, montelukast may be prescribed to treat seasonal allergic rhinitis (allergy symptoms like congestion, difficulty breathing, and itching that occur at a specific time of year) or perennial allergic rhinitis (allergy symptoms that occur year-round) in adults and children.
Montelukast is used to prevent asthma symptoms. It is not a fast-acting asthma relief medication.
Montelukast is classified as a leukotriene receptor antagonist. Leukotrienes are chemicals released by your body in response to an allergen. They cause effects similar to those of histamine. By blocking the release of leukotrienes, these medications prevent the inflammation that causes asthma symptoms and the symptoms of allergic rhinitis.
Montelukast is available as an oral tablet, chewable tablet, and oral granules.
