Indications & Clinical Uses

Montelukast acts on the leukotriene pathway to control respiratory and allergic conditions.

  • Asthma: Improves long‑term control of symptoms and reduces the frequency of exacerbations.
  • Exercise‑induced bronchoconstriction: Prevents narrowing of airways triggered by physical activity.
  • Allergic rhinitis: Alleviates nasal congestion, sneezing and itching associated with seasonal allergies.

How It Works

  • Montelukast is a selective antagonist of the cysteinyl leukotriene receptor CysLT1. By binding to this receptor, it blocks the action of leukotrienes that cause bronchoconstriction, mucus secretion, and airway edema, thereby reducing airway inflammation and improving airflow in the respiratory tract.

Side Effects

Montelukast may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

  • Headache: mild to moderate intensity.
  • Abdominal pain: occasional discomfort or cramping.
  • Cough: transient irritation of the throat.
  • Dyspepsia: indigestion or upset stomach.

Serious or Rare Side Effects

  • Mood changes or suicidal thoughts: monitor for depression or anxiety.
  • Angioedema: swelling of face, lips, tongue, or throat.
  • Anaphylaxis: severe allergic reaction requiring immediate medical attention.

Precautions & Warnings

Before prescribing Montelukast, clinicians should consider several safety measures.

  • Assess asthma control before initiating: ensure patient is on appropriate inhaled therapy.
  • Monitor for neuropsychiatric events: watch for mood changes, depression, or suicidal thoughts.
  • Use with caution in hepatic impairment: adjust therapy if liver function is compromised.
  • Avoid in patients with known hypersensitivity to montelukast or any excipients.
  • Store at ambient temperature below 25°C: keep in the original pack, protect from moisture.

Avoid Interactions

Montelukast can interact with other medicines, requiring attention to the level of risk.

Major Interactions (Avoid)

  • Phenobarbital, rifampin, carbamazepine: may markedly reduce montelukast plasma concentrations.
  • Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase montelukast exposure and risk of adverse effects.

Moderate Interactions (Monitor Closely)

  • Warfarin: potential increase in INR; monitor coagulation parameters.
  • Theophylline: additive bronchial effects; observe for changes in respiratory status.
  • Epinephrine: may diminish the acute relief provided by epinephrine in severe asthma attacks; monitor response.

Frequently Asked Questions

Montelukast Sandoz is used as a maintenance therapy for asthma, to prevent exercise‑induced bronchoconstriction, and to relieve symptoms of allergic rhinitis such as nasal congestion, sneezing and itching.

Montelukast selectively blocks the cysteinyl leukotriene receptor CysLT1, preventing leukotrienes from causing bronchoconstriction, mucus production, and airway inflammation, which helps keep the airways open and reduces allergic symptoms.

The dose of Montelukast is determined by the prescribing healthcare professional based on the patient’s age, condition and response. Typical dosing ranges are established in clinical guidelines, but the exact regimen should be set by a qualified prescriber.

Safety data for Montelukast during pregnancy and lactation are limited. It should only be used if the potential benefit justifies any potential risk to the fetus or infant, and the decision must be made in consultation with a healthcare provider.

To order, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Montelukast targets leukotriene‑mediated inflammation, whereas inhaled corticosteroids act broadly on airway inflammation. Montelukast is often used as an add‑on therapy for patients whose asthma is not fully controlled with inhaled steroids, but it does not replace the anti‑inflammatory effect of corticosteroids.

Montelukast tablets should be stored at ambient temperature below 25 °C, kept in the original packaging, and protected from moisture and direct sunlight. Do not store in a location where temperature may exceed the recommended range.

Montelukast is taken orally as a tablet. The tablet should be swallowed whole with water and can be taken with or without food. Patients should follow the dosing schedule prescribed by their healthcare professional.

Serious risks include neuropsychiatric events such as mood changes, depression, or suicidal thoughts, as well as rare allergic reactions like angioedema and anaphylaxis. Any sudden changes in mood or signs of severe allergic response should prompt immediate medical evaluation.

Montelukast should not be used by individuals with known hypersensitivity to the drug or any of its excipients. Caution is advised in patients with severe hepatic impairment, and it should be prescribed only after a healthcare professional assesses the suitability for each patient.
