Indications & Clinical Uses

Montelukast acts on the leukotriene pathway to control inflammatory airway conditions.

  • Asthma: reduces frequency and severity of asthma attacks and improves symptom control.
  • Exercise‑induced bronchoconstriction: prevents narrowing of airways during physical activity.
  • Allergic rhinitis: alleviates nasal congestion, sneezing and itching caused by allergic triggers.

How It Works

  • Montelukast selectively blocks the cysteinyl leukotriene receptor CysLT1, preventing leukotrienes D4, C4 and E4 from binding. This inhibition reduces bronchoconstriction, vascular permeability, mucus secretion and inflammatory cell recruitment in the respiratory tract, thereby improving airway function and decreasing allergic inflammation.

Side Effects

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

Common Side Effects

  • Headache: mild to moderate intensity.
  • Upper respiratory tract infection: symptoms of cold or flu.
  • Abdominal pain: occasional discomfort.
  • Cough: transient irritation.
  • Diarrhoea: loose stools.
  • Rash: mild skin irritation.

Serious or Rare Side Effects

  • Mood changes: depression or suicidal thoughts.
  • Allergic reactions: hives, swelling, or anaphylaxis.
  • Liver enzyme elevation: abnormal liver function tests.
  • Stevens‑Johnson syndrome: severe skin blistering.
  • Angioedema: rapid swelling of face or throat.

Precautions & Warnings

Before using Montelukast, consider the following safety measures.

  • Pregnancy: consult a healthcare professional; safety data are limited.
  • Breastfeeding: discuss potential risks with a physician.
  • Liver disease: use with caution; monitor hepatic function.
  • Concomitant asthma therapy: do not replace inhaled steroids without medical advice.
  • Age restrictions: follow prescribing information for pediatric use.
  • Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Montelukast may interact with other medicines; monitoring is advised.

Major Interactions (Avoid)

  • Phenobarbital: may lower montelukast plasma concentrations.
  • Rifampin: can reduce therapeutic effect by inducing metabolism.
  • Ketoconazole: may increase montelukast levels, raising risk of side effects.

Moderate Interactions (Monitor Closely)

  • Warfarin: potential increase in INR; monitor coagulation.
  • Theophylline: may enhance bronchodilator effect.
  • Beta‑agonists: additive bronchodilation; observe for excessive response.

Frequently Asked Questions

Montelukast Arrow Lab is prescribed to manage asthma, prevent exercise‑induced bronchoconstriction, and relieve symptoms of allergic rhinitis such as nasal congestion, sneezing and itching.

Montelukast blocks the CysLT1 receptor, preventing cysteinyl leukotrienes from triggering bronchoconstriction, mucus production and inflammation in the airways, which helps keep breathing easier and reduces allergic responses.

The specific dose and dosing schedule are determined by the prescribing clinician based on the patient’s age, condition severity and response to therapy. Patients should follow the prescriber’s instructions exactly.

Safety data for Montelukast in pregnancy are limited, so it should only be used if the potential benefit justifies any risk. Women who are breastfeeding should discuss possible effects with their healthcare provider.

Submit an enquiry on the product page at gnhindia.com with 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 is a leukotriene receptor antagonist taken orally, whereas inhaled corticosteroids are anti‑inflammatory agents delivered directly to the lungs. Montelukast is often used as an add‑on therapy for patients who need additional control beyond inhaled steroids, but it does not replace the anti‑inflammatory benefits of steroids.

Store the tablets below 25 °C in their original container, protecting them from moisture, heat and direct sunlight to maintain potency throughout the shelf life.

Montelukast Arrow Lab is taken orally, usually as a whole tablet with or without food, according to the prescriber’s directions. Swallow the tablet whole; do not crush or chew unless instructed otherwise.

Serious concerns 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 any of these symptoms appear.

Montelukast should be avoided in individuals with known hypersensitivity to the drug or any of its components. It is also not recommended for patients with uncontrolled severe liver disease without close medical supervision.
