Indications & Clinical Uses

Montelukast acts on the leukotriene pathway to reduce airway inflammation and bronchoconstriction.

  • Asthma: improves control of chronic asthma and reduces frequency of exacerbations.
  • Allergic rhinitis: relieves nasal congestion, sneezing and itching caused by seasonal or perennial allergies.
  • Exercise‑induced bronchoconstriction: prevents narrowing of the airways during or after physical activity.

How It Works

  • Montelukast selectively blocks the cysteinyl leukotriene receptor CysLT1, preventing leukotriene D4 from binding. This inhibition reduces leukotriene‑mediated bronchoconstriction, vascular permeability, and inflammatory cell recruitment in the respiratory tract, thereby improving airway patency and decreasing allergic inflammation.

Side Effects

Montelukast is generally well tolerated, but adverse reactions can occur.

Common Side Effects

  • Headache: mild to moderate pain in the head region.
  • Upper respiratory tract infection: symptoms of cold or flu.
  • Abdominal pain: discomfort in the stomach area.
  • Cough: persistent dry cough.
  • Diarrhoea: loose stools.
  • Rash: mild skin irritation or redness.

Serious or Rare Side Effects

  • Mood changes: depression, anxiety, or suicidal thoughts.
  • Allergic reactions: hives, swelling, or difficulty breathing.
  • Liver enzyme elevation: abnormal liver function tests.
  • Stevens‑Johnson syndrome: severe skin blistering.
  • Angio‑edema: rapid swelling of face, lips, or tongue.
  • Anaphylaxis: life‑threatening systemic allergic response.

Precautions & Warnings

Montelukast should be used with consideration of the following precautions.

  • Pregnancy: consult a healthcare provider; safety data are limited.
  • Breastfeeding: discuss risks and benefits with a clinician.
  • Hepatic impairment: monitor liver function in patients with liver disease.
  • Psychiatric disorders: observe for mood changes or suicidal ideation.
  • Drug interactions: review concomitant medications for potential interactions.
  • Store at ambient temperature: keep below 25°C, retain in original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Montelukast may interact with other medicines; monitoring is advised.

Major Interactions (Avoid)

  • Phenobarbital: may reduce montelukast plasma concentrations.
  • Rifampin: can decrease therapeutic effect by inducing metabolism.

Moderate Interactions (Monitor Closely)

  • Antidepressants (SSRIs, SNRIs): potential additive psychiatric effects.
  • Warfarin: occasional reports of altered INR; monitor coagulation.
  • Other leukotriene modifiers: no added benefit and increased risk of side effects.
  • CYP3A4 inhibitors (ketoconazole, erythromycin): may increase montelukast levels.
  • CYP2C9 inhibitors (fluconazole): possible modest increase in exposure.

Frequently Asked Questions

Montelukast Eurogenerics is prescribed to manage chronic asthma, relieve symptoms of allergic rhinitis, and prevent exercise‑induced bronchoconstriction. It works by reducing airway inflammation and narrowing, helping patients achieve better respiratory control.

Montelukast blocks the cysteinyl leukotriene receptor CysLT1, preventing leukotriene D4 from triggering bronchoconstriction and inflammation. This selective antagonism reduces airway swelling, mucus production, and smooth‑muscle tightening, improving breathing.

The specific dose of Montelukast Eurogenerics is determined by a prescriber based on the patient’s age, condition severity, and clinical response. Healthcare professionals tailor the regimen to each individual’s needs.

Safety data for Montelukast in pregnancy are limited, so it should only be used if the potential benefit outweighs the risk and after consulting a healthcare provider. While breastfeeding, discuss possible effects with a clinician, as the drug can be excreted in breast milk.

To place an 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 belongs to the leukotriene receptor antagonist class, offering an oral alternative to inhaled corticosteroids or long‑acting beta‑agonists. It is particularly useful for patients with aspirin‑sensitive asthma or those who prefer a once‑daily tablet, but it may be less potent for acute symptom relief compared with inhaled bronchodilators.

Store Montelukast Eurogenerics at ambient temperature, below 25 °C. Keep the tablets in the original container, protect them from moisture, heat and direct sunlight to maintain stability and potency.

Montelukast Eurogenerics is taken orally, usually as a whole tablet with or without food. The exact timing (e.g., morning or evening) is set by the prescribing clinician based on the therapeutic goal.

Serious risks include mood changes such as depression or suicidal thoughts, severe allergic reactions like anaphylaxis, and rare skin conditions such as Stevens‑Johnson syndrome. Patients should seek immediate medical attention if they experience any of these symptoms.

Montelukast is contraindicated in individuals with known hypersensitivity to the drug or any of its components. Patients with uncontrolled psychiatric disorders should use it only under close medical supervision.
