Montelukast Teva (Montelukast Sodium)

Montelukast, the active ingredient in Montelukast Teva, is a leukotriene receptor antagonist presented as an oral tablet for oral use. It is used to manage asthma, allergic rhinitis, and exercise‑induced bronchoconstriction in adults and children. By selectively blocking cysteinyl leukotriene receptors, it helps reduce airway inflammation, bronchoconstriction, and related symptoms.

GNH USA supplies Montelukast Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable logistics for global distribution.

Montelukast is a leukotriene receptor antagonist used to treat conditions driven by leukotriene‑mediated inflammation.

- Asthma: improves long‑term control and reduces the frequency of exacerbations. - Allergic rhinitis: relieves nasal congestion, sneezing, itching and rhinorrhea. - Exercise‑induced bronchoconstriction: prevents airway narrowing that occurs during physical activity.

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

Common Side Effects: - Headache: mild to moderate intensity. - Abdominal pain or dyspepsia. - Cough or throat irritation. - Dizziness or fatigue. - Nasopharyngitis. - Diarrhoea.

Serious or Rare Side Effects: - Neuropsychiatric events such as agitation, depression, suicidal thoughts or behaviour. - Severe allergic reactions including rash, angio‑edema or anaphylaxis. - Hepatic enzyme elevations. - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Parotid gland enlargement. - Blood dyscrasias (rare).

When prescribing Montelukast, clinicians should consider several safety aspects.

- Assess asthma control: ensure optimal inhaled therapy before adding Montelukast. - Monitor neuropsychiatric symptoms: watch for mood changes, depression or suicidal ideation. - Use with caution in hepatic impairment: dose adjustment may be required. - Avoid in patients with known hypersensitivity to Montelukast or any excipients. - Review concomitant medications for potential interactions. - Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Montelukast may interact with other medicines, requiring attention to the level of risk.

Major Interactions (Avoid): - Phenobarbital, rifampin or St. John's wort: strong enzyme inducers that can markedly reduce Montelukast plasma concentrations.

Moderate Interactions (Monitor Closely): - Warfarin: possible alteration of anticoagulant effect; monitor INR. - Carbamazepine: may modestly decrease Montelukast exposure. - Fluconazole: potential increase in Montelukast levels. - Oral contraceptives: Montelukast may slightly reduce hormonal efficacy; advise backup contraception if needed.
