Neo Furadantin (Nitrofurantoin, Macrocrystalline)

Nitrofurantoin, the active ingredient in Neo Furadantin, is a nitrofuran antibiotic presented as an oral dosage form for oral use. It treats uncomplicated urinary tract infections in adult patients by targeting bacteria in the urinary tract.

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

Neo Furadantin belongs to the nitrofuran class and is used to manage infections of the urinary system.

- Uncomplicated urinary tract infections: provides bacterial eradication in the bladder and urethra, relieving symptoms and preventing progression. - Recurrent urinary tract infection prophylaxis: reduces the frequency of future infections when administered as directed by a healthcare professional.

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

Common Side Effects: - Nausea: mild to moderate upset stomach. - Headache: transient cranial discomfort. - Urine discoloration: yellow‑brown tint without clinical significance.

Serious or Rare Side Effects: - Pulmonary toxicity: interstitial lung disease or acute respiratory distress. - Hepatic injury: elevated liver enzymes or hepatitis. - Hemolytic anemia in G6PD‑deficient patients: rapid red‑cell destruction. - Severe allergic reactions: rash, angioedema, or anaphylaxis. - Peripheral neuropathy: tingling or numbness in extremities. - Acute kidney injury: reduced renal function, especially in patients with pre‑existing impairment.

Before prescribing Neo Furadantin, clinicians should consider several safety measures.

- Assess renal function: ensure adequate glomerular filtration before initiating therapy. - Monitor pulmonary status: watch for new cough or dyspnea indicating lung toxicity. - Evaluate G6PD deficiency: avoid in patients with known deficiency to prevent hemolysis. - Check for hypersensitivity: discontinue if rash, swelling, or anaphylaxis occurs. - Use caution in hepatic impairment: adjust therapy if liver disease is present. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Nitrofurantoin can interact with other medicines, altering its effectiveness or safety.

Major Interactions (Avoid): - Probenecid: reduces renal clearance, increasing nitrofurantoin toxicity. - Antacids containing magnesium or aluminum: markedly decrease oral absorption. - Trimethoprim‑sulfamethoxazole: additive risk of renal toxicity.

Moderate Interactions (Monitor Closely): - Warfarin: may enhance anticoagulant effect, requiring INR monitoring. - Oral contraceptives: possible reduction in contraceptive efficacy. - Diuretics: may affect renal function and nitrofurantoin excretion.
