What is Montelukast?

Montelukast, the active ingredient in this product, is a leukotriene receptor antagonist presented as an oral tablet for oral administration. It selectively blocks cysteinyl leukotriene receptors, helping to control bronchoconstriction and inflammation associated with asthma, allergic rhinitis, and exercise‑induced bronchoconstriction in both adults and children.

GNH USA supplies Montelukast as a licensed, GMP‑qualified, GDP‑compliant international pharmaceutical supplier, providing the medication to hospitals, pharmacies and clinics worldwide under strict quality standards.

What is Montelukast used for?

Montelukast is indicated for conditions involving leukotriene‑mediated airway inflammation. - Asthma: reduces frequency of symptoms and improves lung function. - Allergic rhinitis: alleviates nasal congestion, sneezing and itching. - Exercise‑induced bronchoconstriction: prevents narrowing of airways during physical activity.

What are the side effects of Montelukast?

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

Common Side Effects: - Headache - Abdominal pain - Cough - Nausea

Serious or Rare Side Effects: - Allergic reactions such as rash or angioedema - Mood changes including depression or suicidal thoughts - Elevated liver enzymes - Eosinophilic granulomatosis with polyangiitis (Churg‑Strauss syndrome)

What precautions apply to Montelukast?

When prescribing Montelukast, clinicians should consider several safety aspects. - Pregnancy: safety not established; use only if benefit outweighs risk. - Breastfeeding: unknown; evaluate potential risk to infant. - Hepatic impairment: use with caution and monitor liver function. - Neuropsychiatric events: monitor for mood changes, depression, or suicidal thoughts. - Drug interactions: review concomitant medications for potential interactions. - Store below 25°C: keep in original container, protect from moisture.

What does Montelukast interact with?

Montelukast can interact with other medicines; interactions vary in clinical significance.

Major Interactions (Avoid): - Phenobarbital: may reduce plasma concentrations of Montelukast. - Rifampin: may decrease efficacy by inducing metabolism. - Ketoconazole: may increase Montelukast levels.

Moderate Interactions (Monitor Closely): - Warfarin: possible alteration of anticoagulant effect; monitor INR. - Beta‑agonists: additive bronchodilation; monitor response. - Antidepressants: potential for increased neuropsychiatric effects.

Frequently asked questions

What is Montelukast used for?+
Montelukast is prescribed to manage asthma, allergic rhinitis, and exercise‑induced bronchoconstriction. By targeting leukotriene pathways, it helps reduce airway inflammation, prevent bronchospasm, and relieve nasal symptoms such as congestion, sneezing, and itching.
How does Montelukast work?+
Montelukast selectively blocks the cysteinyl leukotriene receptor CysLT1. This inhibition prevents leukotriene D4 from binding, which in turn reduces bronchoconstriction, mucus production, and inflammatory cell recruitment in the respiratory tract.
What is the usual dose of Montelukast?+
The appropriate dose of Montelukast is determined by the prescribing healthcare professional based on the patient’s age, condition, and clinical response. Typical regimens may vary, but the exact dosage and frequency should always follow the prescriber’s instructions.
Is Montelukast safe during pregnancy or breastfeeding?+
Safety data for Montelukast in pregnancy and lactation are limited. It should be used only if the potential benefit justifies any possible risk to the fetus or infant, and the decision should be made in consultation with a qualified healthcare provider.
How do I order Montelukast from GNH USA?+
To place an order, submit an enquiry on the product page at gnh-usa.com specifying the required quantity. GNH USA 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.
How does Montelukast compare with the main alternative drug or class?+
Montelukast belongs to the leukotriene receptor antagonist class, offering an oral alternative to inhaled corticosteroids or other leukotriene blockers such as zafirlukast. It is generally well‑tolerated and convenient for once‑daily dosing, but the choice depends on individual disease severity, response, and physician preference.
What are the storage and handling requirements for Montelukast?+
Montelukast tablets should be stored below 25 °C in their original packaging, protected from moisture and direct sunlight. Keep the container tightly closed and out of reach of children to maintain product stability and potency.
How is Montelukast administered?+
Montelukast is taken orally as a tablet, swallowed whole with or without food. The tablet should be consumed at the same time each day, and patients should follow the dosing schedule prescribed by their healthcare professional.
What are the most serious risks to watch for while taking Montelukast?+
Serious adverse events include allergic reactions such as rash or angioedema, neuropsychiatric effects like depression or suicidal thoughts, elevated liver enzymes, and rare conditions such as eosinophilic granulomatosis with polyangiitis. Any of these symptoms warrant immediate medical attention.
Who should not use Montelukast?+
Montelukast is contraindicated in individuals with known hypersensitivity to the drug or any of its excipients. Patients with a history of severe neuropsychiatric disorders or uncontrolled liver disease should discuss risks with their clinician before initiating therapy.
