Nitrofurantoïne Activase (Nitrofurantoin)

Nitrofurantoin, the active ingredient in Nitrofurantoïne Activase, is a nitrofuran antibacterial presented as an oral tablet for oral use. It treats uncomplicated urinary tract infections in adult patients. GNH USA supplies Nitrofurantoïne 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 susceptible uropathogens in the bladder, relieving symptoms. - Acute cystitis: provides bactericidal activity that clears infection and reduces discomfort. - Prophylaxis of recurrent urinary tract infection: reduces recurrence when administered as directed by a prescriber.

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

Common Side Effects: - Nausea: occasional upset stomach after dosing. - Diarrhea: loose stools that may occur during therapy. - Headache: mild to moderate headache reported by some patients. - Metallic taste: transient alteration in taste perception.

Serious or Rare Side Effects: - Pulmonary toxicity: interstitial lung disease or acute respiratory distress, requiring immediate medical attention. - Hepatic injury: signs of liver dysfunction such as jaundice or elevated enzymes. - Hemolytic anemia in G6PD‑deficient patients: rapid drop in red blood cells. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before prescribing Nitrofurantoin, clinicians should consider several safety factors. - Renal function: assess creatinine clearance, as reduced renal function limits urinary excretion. - G6PD deficiency: avoid in patients with known deficiency due to risk of hemolysis. - Pregnancy: category B, generally considered safe but use only if clearly needed. - Elderly patients: monitor for reduced renal function and potential toxicity. - Concomitant use with drugs that may cause lung injury: observe for respiratory symptoms. - Store at room temperature: keep in the original container, protect from moisture and light.

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

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: may decrease nitrofurantoin absorption. - Probenecid: can increase nitrofurantoin plasma concentrations, raising toxicity risk. - Cimetidine: may raise nitrofurantoin levels, enhancing adverse effects. - Warfarin: potentiates anticoagulant effect, requiring closer INR monitoring.

Moderate Interactions (Monitor Closely): - Fluoroquinolones: additive risk of tendonitis or tendon rupture. - Macrolide antibiotics (e.g., erythromycin): may increase risk of liver toxicity when used together.
