What is Montelukast?

Montelukast is a leukotriene receptor blocker used to manage chronic asthma, exercise-induced breathing issues, and allergic rhinitis. It is often provided in tablet, chewable tablet, and granule form for different age groups. By reducing airway inflammation, Montelukast helps patients breathe more comfortably and prevents long-term flare-ups.

Montelukast used for

This medicine is used for:

  • Long-term management of asthma

  • Prevention of exercise-induced bronchoconstriction

  • Relief from seasonal or perennial allergic rhinitis

  • Reducing nighttime asthma symptoms in children

It is not meant for emergency asthma attacks.

Chemical composition

Montelukast contains the active ingredient Montelukast Sodium, a selective leukotriene receptor antagonist. Inactive ingredients vary by form but may include mannitol, cellulose, flavoring agents (in chewables), and lactose-free fillers.

Montelukast Mechanism

When allergens or irritants enter the airway, the body releases leukotrienes, chemicals that cause inflammation, tightening of airway muscles, and excess mucus. Montelukast blocks leukotriene receptors, preventing these reactions and helping keep airways open.

How does it help with asthma and allergies?

Montelukast helps maintain steady breathing by reducing airway swelling and preventing sudden tightening. For allergy sufferers, it decreases symptoms like sneezing, nasal congestion, watery eyes, and itching. When taken daily, it lowers the frequency and intensity of asthma attacks and improves overall respiratory comfort.

What are the other benefits?

  • Reduces nighttime coughing

  • Helps patients who cannot tolerate inhaled corticosteroids

  • Improves breathing comfort during physical activity

  • Provides once-daily symptom control

  • Safe and effective for children when used correctly

  • 10 mg tablets (for adults)

  • 5 mg chewable tablets (for children 6–14 years)

  • 4 mg chewable tablets or oral granules (for children 2–5 years)

Your doctor will choose the appropriate strength based on age and condition.

  • Usually taken once daily in the evening for asthma.

  • For allergies, it may be taken once daily anytime, based on medical advice.

  • Chewable tablets should be fully chewed before swallowing.
