Montelukast: Uses, Benefits, and Side Effects

Introduction to Montelukast

Montelukast is a prescription medication commonly used to manage and prevent symptoms of asthma, allergies, and breathing difficulties. It belongs to a class of drugs known as leukotriene receptor antagonists, which work by blocking the action of leukotrienes — chemicals in the body that cause inflammation, constrict airways, and lead to allergy symptoms.

If you or a loved one suffer from asthma or chronic allergies, Montelukast could be a life-changing medication to manage symptoms and improve your quality of life.

How Montelukast Works

Leukotrienes are chemicals your body releases when you breathe in an allergen, such as pollen. These chemicals cause swelling in your lungs and tighten the muscles around your airways. By blocking leukotrienes, Montelukast reduces inflammation, prevents airway narrowing, and improves airflow, making breathing easier.

Dosage and Administration

Montelukast is available in several forms, including:

• Tablets (10 mg): Typically taken once daily, usually in the evening.
• Chewable Tablets (4 mg and 5 mg): Commonly prescribed for children aged 2-5 years.
• Granules (4 mg): Often given to younger children by mixing with a spoonful of food.

It is important to follow your doctor’s instructions regarding the dosage and how to take Montelukast. For asthma, the medicine is usually taken once in the evening. For exercise-induced bronchoconstriction, it is taken at least 2 hours before physical activity.
