Nitrofurantoïne Focus Care (Nitrofurantoin)

Nitrofurantoin, the active ingredient in Nitrofurantïne Focus Care, is a nitrofuran antibiotic presented as a tablet for oral use. It treats uncomplicated urinary tract infections, including acute cystitis in adults, and is also used for prophylaxis of recurrent infections by targeting bacteria that colonize the bladder and urethra.

GNH USA supplies Nitrofurantïne Focus Care as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The product meets EU quality standards and is manufactured under strict GMP conditions.

Nitrofurantoin is indicated for urinary tract infections and related conditions.

Uncomplicated urinary tract infection: eliminates the causative bacteria in the bladder, relieving symptoms and preventing progression. Acute cystitis: provides rapid bacteriostatic or bactericidal activity to resolve infection. Recurrent urinary tract infection prophylaxis: reduces the frequency of future infections when taken as a preventive regimen.

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

Common Side Effects: - Nausea - Loss of appetite - Headache - Diarrhea

Serious or Rare Side Effects: - Pulmonary toxicity (interstitial pneumonitis or fibrosis) - Hepatic injury (hepatitis, jaundice) - Severe allergic reactions (anaphylaxis, Stevens‑Johnson syndrome)

When prescribing Nitrofurantïne Focus Care, clinicians should consider several safety measures. - Assess renal function: avoid use in patients with creatinine clearance below 60 mL/min. - Monitor for pulmonary symptoms: discontinue if cough, dyspnea, or fever develop. - Avoid in patients with known G6PD deficiency: risk of hemolysis. - Use with caution during pregnancy: limited data; consider alternatives when possible. - Limit duration of therapy: prolonged use increases risk of liver and lung toxicity. - Store at ambient temperature below 25°C: keep in the original container, protect from moisture and light.

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

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: reduce nitrofurantoin absorption. - Probenecid: increases plasma concentration, raising toxicity risk. - Trimethoprim‑sulfamethoxazole: additive bone‑marrow suppression.

Moderate Interactions (Monitor Closely): - Warfarin: may enhance anticoagulant effect, requiring INR monitoring. - NSAIDs: can worsen renal impairment when combined. - Diuretics: may increase risk of crystalluria, especially in dehydrated patients.
