Indications & Clinical Uses

Montelukast Teva belongs to the leukotriene‑modifier class and is used to control inflammatory airway diseases.

  • Asthma: improves long‑term control and reduces the frequency of exacerbations.
  • Allergic rhinitis: relieves nasal congestion, sneezing and itchy eyes associated with seasonal allergies.
  • Exercise‑induced bronchoconstriction: prevents airway narrowing that occurs during physical activity.

How It Works

  • Montelukast Sodium 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 may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects

  • Headache: mild to moderate discomfort.
  • Abdominal pain: occasional stomach discomfort.
  • Cough: transient irritation of the throat.
  • Nausea: occasional feeling of queasiness.
  • Dizziness: brief episodes of light‑headedness.
  • Fatigue: mild tiredness.

Serious or Rare Side Effects

  • Angioedema: swelling of face, lips or tongue that may impair breathing.
  • Neuropsychiatric events: mood changes, depression or suicidal thoughts.
  • Severe rash: including Stevens‑Johnson syndrome.
  • Hepatic injury: abnormal liver function tests.
  • Anaphylaxis: rare, life‑threatening allergic reaction.

Precautions & Warnings

Before prescribing Montelukast, clinicians should consider several safety aspects.

  • Assess asthma control: ensure baseline therapy is optimized.
  • Monitor neuropsychiatric symptoms: watch for mood changes or suicidal ideation.
  • Use caution in hepatic impairment: adjust therapy if liver disease is present.
  • Avoid in patients with known hypersensitivity to montelukast or any excipients.
  • Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Avoid Interactions

Montelukast can interact with other medicines that affect its metabolism or pharmacodynamic profile.

Major Interactions (Avoid)

  • Ritonavir: may increase montelukast plasma concentrations.
  • Phenobarbital: may markedly reduce montelukast exposure.
  • Carbamazepine: may lower montelukast levels, reducing efficacy.

Moderate Interactions (Monitor Closely)

  • Fluconazole: can raise montelukast concentrations modestly.
  • Warfarin: monitor INR as montelukast may affect anticoagulation.
  • Theophylline: observe for additive bronchodilator effects.

Frequently Asked Questions

Montelukast Teva is a prescription medication indicated for the long‑term management of asthma and for relief of symptoms associated with seasonal or perennial allergic rhinitis. It may also be used to prevent exercise‑induced bronchoconstriction in patients who experience airway narrowing during physical activity.

Montelukast Sodium works by selectively blocking the cysteinyl leukotriene receptor CysLT1. By preventing leukotriene D4 from binding, it reduces bronchoconstriction, vascular leakage, and inflammatory cell recruitment in the airways, leading to improved breathing and decreased allergy‑related inflammation.

The appropriate dose of Montelukast Teva is determined by the prescribing healthcare professional based on the patient’s age, weight, disease severity, and response to therapy. Dosage instructions are provided on the prescription label and should be followed exactly as directed.

Safety data for Montelukast during pregnancy and lactation are limited. The drug should only be used if the potential benefit to the mother outweighs any possible risk to the fetus or infant. Healthcare providers will evaluate individual circumstances before prescribing.

To place an order, submit an enquiry on the Montelukast Teva 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‑modifier class, offering an oral alternative to inhaled corticosteroids or long‑acting beta‑agonists. While inhaled steroids directly reduce airway inflammation, montelukast provides a convenient once‑daily tablet that can be added to existing regimens, especially for patients with allergic components or difficulty using inhalers.

Montelukast Teva should be stored at room temperature, below 25 °C (77 °F). Keep the tablets in the original blister pack or bottle, protect them from moisture, heat and direct sunlight, and keep out of reach of children.

Montelukast Teva is taken orally as a tablet, usually once daily in the evening. The tablet should be swallowed whole with a glass of water and can be taken with or without food. Patients should follow the dosing schedule prescribed by their clinician.

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

Montelukast Teva is contraindicated in individuals with known hypersensitivity to montelukast sodium or any of the tablet’s excipients. Caution is also advised for patients with severe hepatic impairment, and it should be avoided in those who have experienced serious allergic reactions to leukotriene‑modifier drugs.
