What it's for (Indications)

  • Montelukast is indicated for the control and prevention of symptoms caused by asthma (a chronic inflammatory disease of the lungs, characterized by narrowing of the airways) in patients 12 months and older.
  • It is also used for the acute prevention of exercise-induced bronchoconstriction (EIB) in patients 6 years and older.
  • Additionally, it is used to relieve symptoms of allergic rhinitis, including seasonal allergic rhinitis (in patients 2 years and older) and perennial allergic rhinitis (in patients 6 months and older), such as sneezing, stuffy/runny/itchy nose, and hay fever.

Dosage Information

Type Guideline
Standard Montelukast should be administered orally once daily. Tablets should be swallowed whole with a glass of water and should not be crushed, chewed, or broken. Oral granules must be administered within 15 minutes after opening the sachet, with or without mixing with food. Take regularly for consistent effect. If a dose is missed, take it as soon as remembered unless it's almost time for the next dose; do not double dose. **Asthma:** Administer once daily in the evening. * **Patients 15 years and older:** One 10-mg tablet. * **Patients 6 to 14 years:** One 5-mg chewable tablet. * **Patients 2 to 5 years:** One 4-mg chewable tablet or one sachet of 4-mg oral granules. * **Patients 12 months to 23 months:** One sachet of 4-mg oral granules. **Acute Prevention of Exercise-Induced Bronchoconstriction (EIB):** Administer one dose at least 2 hours before exercise. * **Patients 15 years and older:** One 10-mg tablet. * **Patients 6 to 14 years:** One 5-mg chewable tablet. * An additional dose should not be taken within 24 hours of a previous dose. Patients already taking montelukast daily for another indication should not take an additional dose for EIB. **Allergic Rhinitis:** Administer once daily. The timing of administration can be in the evening for better control of nocturnal symptoms and adherence, or as directed by a healthcare provider. * **Seasonal Allergic Rhinitis (patients 2 years and older):** * **Patients 15 years and older:** One 10-mg tablet. * **Patients 6 to 14 years:** One 5-mg chewable tablet. * **Patients 2 to 5 years:** One 4-mg chewable tablet or one sachet of 4-mg oral granules. * **Perennial Allergic Rhinitis (patients 6 months and older):** * **Patients 15 years and older:** One 10-mg tablet. * **Patients 6 to 14 years:** One 5-mg chewable tablet. * **Patients 2 to 5 years:** One 4-mg chewable tablet or one sachet of 4-mg oral granules. * **Patients 6 months to 23 months:** One sachet of 4-mg oral granules. **Patients with both Asthma and Allergic Rhinitis:** Take only one dose daily in the evening.

These include, but are not limited to, agitation, aggression, depression, sleep disturbances, hallucinations, tremors, suicidal thoughts and behavior. Patients and caregivers should be advised to be alert for the emergence or worsening of any neuropsychiatric symptoms and to seek medical advice immediately if these changes occur.
  • Patients and caregivers should be advised to be alert for the emergence or worsening of any neuropsychiatric symptoms and to seek medical advice immediately if these changes occur.
  • Montelukast is not indicated for the reversal of bronchospasm in acute asthma attacks and should not be used as a rescue medication.
  • Patients should be advised to have appropriate rescue medication available.
  • Do not abruptly substitute montelukast for oral or inhaled corticosteroid therapy.
  • Dosage reduction of systemic corticosteroids should be gradual and under medical supervision.
  • Systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss Syndrome, has been reported.
  • These events are sometimes associated with the reduction of oral corticosteroid therapy.
  • Discontinue montelukast if symptoms of Churg-Strauss Syndrome appear.
  • Use with caution in patients with liver disease.
  • Regular liver function tests may be required during treatment.
  • Inform your doctor about any history of liver disease.
  • Severe allergic reactions, including anaphylaxis, angioedema, and hives, can occur.
  • Seek immediate medical attention if you experience symptoms such as difficulty breathing or swelling of the face, lips, tongue, or throat.
  • While montelukast is not known to cause lung infections, people with asthma are at an increased risk of developing respiratory infections, including pneumonia, bronchitis, or tuberculosis.
  • Seek medical attention if symptoms such as fever, cough, or difficulty breathing develop.
  • Montelukast is not a substitute for non-steroidal anti-inflammatory drugs (NSAIDs) for individuals with aspirin-sensitive asthma.
  • Chewable tablets may contain aspartame, a source of phenylalanine.
  • Patients with phenylketonuria should inform their doctor prior to use.
  • The effects of montelukast during pregnancy and breastfeeding are undetermined, and caution is advised.

How it Works (Mechanism of Action)
Montelukast is a leukotriene receptor antagonist that binds with high affinity and selectivity to the cysteinyl leukotriene type-1 (CysLT1) receptor. It works by blocking the action of cysteinyl leukotrienes (LTC4, LTD4, LTE4), which are products of arachidonic acid metabolism released from cells like mast cells and eosinophils. These leukotrienes are involved in the pathophysiology of asthma and allergic rhinitis, causing airway edema, smooth muscle contraction, and inflammation in the airways. By inhibiting these effects, Montelukast reduces inflammation and swelling in the airways, making it easier to breathe and alleviating symptoms of asthma and allergic rhinitis. It is not a bronchodilator or an immunosuppressant.
