Indications & Clinical Uses

Montelukast acts on the leukotriene pathway to control airway inflammation and allergic symptoms.

  • Asthma maintenance therapy: reduces frequency of asthma attacks and improves overall control in patients with persistent asthma.
  • Allergic rhinitis: alleviates nasal congestion, sneezing and itching associated with seasonal or perennial allergic rhinitis.
  • Exercise‑induced bronchoconstriction: prevents narrowing of the airways that can occur during or after physical activity.

How It Works

  • Montelukast selectively blocks the cysteinyl leukotriene receptor CysLT1, preventing leukotriene D4 and related mediators from binding. By inhibiting this pathway, it reduces bronchoconstriction, mucus secretion, vascular permeability, and inflammatory cell recruitment in the respiratory tract, contributing to improved airway function.

Side Effects

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

Common Side Effects

  • Headache
  • Abdominal pain
  • Cough
  • Nausea
  • Dizziness
  • Fatigue

Serious or Rare Side Effects

  • Anaphylaxis or severe allergic reactions
  • Angioedema affecting face, lips or throat
  • Mood changes, including depression or suicidal thoughts
  • Elevated liver enzymes or hepatitis
  • Stevens‑Johnson syndrome or toxic epidermal necrolysis
  • Eosinophilic pneumonia

Precautions & Warnings

When prescribing Montelukast, clinicians should consider several safety and handling precautions.

  • Assess liver function: monitor hepatic enzymes in patients with existing liver disease.
  • Review psychiatric history: observe for mood alterations or suicidal ideation, especially in adolescents.
  • Evaluate for hypersensitivity: discontinue if signs of severe allergic reaction appear.
  • Consider drug interactions: adjust therapy when used with strong enzyme inducers or inhibitors.
  • Use caution in pregnancy: discuss potential risks and benefits with the patient.
  • Store at room temperature: keep below 25 °C, in the original packaging, protected from moisture and direct sunlight.

Avoid Interactions

Montelukast can interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

  • Phenobarbital: may markedly lower montelukast plasma concentrations, reducing therapeutic effect.
  • Rifampin: strong enzyme inducer that can decrease montelukast exposure.
  • Ketoconazole: potent CYP3A4 inhibitor that may raise montelukast levels and risk of side effects.

Moderate Interactions (Monitor Closely)

  • Warfarin: monitor INR as montelukast may affect anticoagulation control.
  • Beta‑agonists: concurrent use may increase risk of bronchospasm or tachycardia.
  • ACE inhibitors: observe for enhanced cough or angioedema when combined.

Frequently Asked Questions

Montelukast Sandoz is prescribed for the long‑term management of persistent asthma, to relieve symptoms of allergic rhinitis such as sneezing and nasal congestion, and to prevent exercise‑induced bronchoconstriction that can limit physical activity.

The drug selectively blocks the cysteinyl leukotriene receptor CysLT1, stopping leukotriene D4 and related molecules from triggering bronchoconstriction, mucus production, and inflammation in the airways, thereby improving breathing and reducing allergic responses.

The exact dose and frequency are determined by the prescribing healthcare professional based on the patient’s age, condition severity, and response to therapy. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety data for Montelukast in pregnancy are limited, and the drug should only be used if the potential benefit justifies any possible risk to the fetus. Caution is also advised during breastfeeding; the prescriber should evaluate the risk‑benefit balance.

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.

Unlike inhaled corticosteroids that target broad inflammation, Montelukast specifically blocks leukotriene‑mediated pathways. It is often used as an add‑on therapy for patients who need additional control or who cannot tolerate steroids, offering a convenient oral option.

Store the tablets at room temperature, preferably below 25 °C, in the original blister pack. Keep them away from moisture, direct sunlight and excessive heat to maintain product stability.

Montelukast is taken orally, usually as a whole tablet with or without food. The exact timing (morning or evening) should follow the prescriber’s guidance to ensure consistent blood levels.

Serious adverse events include severe allergic reactions such as anaphylaxis, angioedema, mood changes including depression or suicidal thoughts, and rare skin conditions like Stevens‑Johnson syndrome. Patients should seek immediate medical attention if any of these occur.

Montelukast should be avoided in individuals with known hypersensitivity to the drug or any of its excipients. Caution is also advised for patients with active liver disease, uncontrolled psychiatric conditions, or those taking medications that may cause major interactions.
