Nefoxef (Fexofenadine Hydrochloride)

Fexofenadine, the active ingredient in Nefoxef, is a second‑generation antihistamine presented as an oral tablet for oral use. It alleviates symptoms of allergic conditions such as nasal congestion, sneezing, itching and hives, and is intended for adults and adolescents seeking non‑sedating relief. It is available without prescription in many European markets and is commonly used to manage seasonal allergies and chronic hives.

GNH USA supplies Nefoxef 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.

Nefoxef (fexofenadine) acts on histamine H1 receptors to relieve allergic manifestations. - Allergic rhinitis: reduces nasal congestion, sneezing, itching, and rhinorrhea, improving overall nasal comfort during exposure to seasonal or perennial allergens. - Seasonal allergic rhinitis: provides non‑sedating relief of hay‑fever symptoms such as itchy eyes, runny nose, and sneezing throughout pollen seasons. - Chronic idiopathic urticaria: diminishes the frequency, size, and itching intensity of hives, offering sustained control of chronic spontaneous urticaria.

Fexofenadine is generally well tolerated, but several adverse reactions have been reported.

Common Side Effects: - Headache: mild to moderate headache may occur. - Dry mouth: sensation of oral dryness. - Nausea: occasional stomach upset. - Fatigue: feeling of tiredness.

Serious or Rare Side Effects: - Angioedema: swelling of lips, tongue or face requiring immediate medical attention. - Cardiac arrhythmia: rare reports of irregular heartbeat. - Anaphylaxis: severe allergic reaction with difficulty breathing.

Before using Nefoxef, consider the following precautions. - Pregnancy: consult a healthcare professional as safety data are limited. - Breastfeeding: use with caution; limited information on excretion in milk. - Renal impairment: dose adjustment may be necessary in patients with reduced kidney function. - Drug interactions: avoid concomitant use with medications that may increase fexofenadine levels. - Store at ambient temperature: keep below 25 °C, retain in original packaging and protect from moisture.

Fexofenadine may interact with certain medicines, affecting its absorption or plasma concentration.

Major Interactions (Avoid): - Ketoconazole: can markedly increase fexofenadine plasma levels. - Erythromycin: may raise systemic exposure and risk of adverse effects. - Ritonavir: strong CYP3A4 inhibition can elevate fexofenadine concentrations.

Moderate Interactions (Monitor Closely): - Antacids containing aluminum or magnesium: may reduce oral absorption of fexofenadine. - Fruit juices (grapefruit, orange, apple): can decrease bioavailability. - Alcohol: may enhance sedation when combined with other CNS depressants.
