Neofuragina (Nitrofurantoin)

Nitrofurantoin, the active ingredient in Neofuragina, is a nitrofuran antibiotic presented as an oral tablet for oral use. It is employed to treat uncomplicated urinary tract infections caused by susceptible bacteria in adult patients. Nitrofurantoin works by disrupting bacterial carbohydrate metabolism, leading to bacterial cell death.

GNH USA supplies Neofuragina as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Neofuragina (nitrofurantoin) is indicated for infections of the urinary tract and related prophylaxis.

- Uncomplicated urinary tract infection: eradicates susceptible uropathogens and relieves urinary symptoms. - Acute cystitis: provides rapid bacterial clearance in lower urinary tract infection. - Prophylaxis of recurrent urinary tract infection: reduces the frequency of repeat infections when used as a preventive regimen.

Nitrofurantoin may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Nausea: mild to moderate upset stomach. - Loss of appetite: reduced desire to eat. - Headache: transient cranial discomfort. - Diarrhea: loose stools. - Mild rash: skin redness or itching. - Metallic taste: altered taste perception.

Serious or Rare Side Effects: - Pulmonary toxicity: interstitial lung disease or acute respiratory distress. - Hepatic injury: elevated liver enzymes or hepatitis. - Severe allergic reactions: anaphylaxis or Stevens‑Johnson syndrome. - Hemolytic anemia in G6PD deficiency: rapid red‑cell destruction. - Peripheral neuropathy: tingling or numbness in extremities.

Before prescribing Neofuragina, clinicians should consider several safety aspects.

- Renal function: assess creatinine clearance; avoid if severely impaired. - Pregnancy: avoid unless benefits outweigh potential risks; category unknown. - G6PD deficiency: contraindicated due to risk of hemolysis. - Elderly patients: monitor for pulmonary toxicity and renal clearance. - Concomitant antacids containing magnesium or aluminum: separate dosing to ensure absorption. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Nitrofurantoin can interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: markedly decrease nitrofurantoin absorption. - Probenecid: may increase nitrofurantoin plasma levels and toxicity. - Cimetidine: can raise serum concentrations, heightening adverse effects.

Moderate Interactions (Monitor Closely): - Warfarin: monitor INR for potential anticoagulant effect alteration. - Methenamine: assess urinary pH to maintain nitrofurantoin activity. - High‑dose vitamin C: may reduce nitrofurantoin efficacy by acidifying urine.
