Nitrofurantoin Activase

Nitrofurantoin, the active ingredient in Nitrofurantoin Activase, is a nitrofuran antibiotic presented as an oral dosage form for oral use. It treats uncomplicated urinary tract infections, including cystitis, in adult patients. GNH USA supplies Nitrofurantoin Activase as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Nitrofurantoin is used to treat bacterial infections of the urinary tract. - Uncomplicated urinary tract infection: eradicates common uropathogens and relieves symptoms such as dysuria and frequency. - Cystitis: provides bactericidal activity against the organisms that cause bladder inflammation. - Prophylaxis of recurrent urinary tract infections: reduces the incidence of repeat infections when taken as a preventive regimen.

Nitrofurantoin may cause a range of adverse reactions.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Loss of appetite: reduced desire to eat. - Headache: transient cranial discomfort. - Diarrhea: loose stools, usually self‑limiting. - Metallic taste: altered taste perception. - Rash: mild skin irritation.

Serious or Rare Side Effects: - Pulmonary toxicity: interstitial lung disease or acute respiratory distress. - Hepatic injury: elevated liver enzymes or hepatitis. - Hemolytic anemia: especially in patients with G6PD deficiency. - Severe allergic reactions: anaphylaxis or Stevens‑Johnson syndrome. - Peripheral neuropathy: numbness or tingling in extremities. - Blood dyscrasias: agranulocytosis or aplastic anemia.

Before prescribing Nitrofurantoin, clinicians should consider several safety factors. - Renal function: assess creatinine clearance; avoid if impaired. - Pregnancy: avoid unless benefits outweigh risks, especially in later trimesters. - Elderly: monitor for accumulation and toxicity. - G6PD deficiency: contraindicated due to risk of hemolysis. - Concomitant medications: review for potential interactions. - Store at room temperature: keep in the original container, protect from moisture.

Nitrofurantoin can interact with other medicines, requiring careful management.

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: markedly reduce absorption. - Probenecid: may increase serum concentrations, raising toxicity risk. - Cimetidine: can elevate nitrofurantoin levels.

Moderate Interactions (Monitor Closely): - Warfarin: may potentiate anticoagulant effect, requiring INR monitoring. - Methenamine: urinary alkalinization can diminish nitrofurantoin efficacy. - Fluoroquinolones: overlapping neurotoxic potential warrants observation.
