Nitrofurantoin is a nitrofuran antibiotic that acts on urinary pathogens causing cystitis and related infections.

Acute uncomplicated cystitis: reduces bacterial load and resolves infection symptoms. Recurrent urinary tract infection prophylaxis: helps prevent recurrence when administered over a longer period. Urinary tract infection in patients with normal renal function: provides targeted antibacterial activity within the urinary tract.

Nitrofurantoin may cause a range of adverse reactions, from mild gastrointestinal symptoms to rare but serious organ toxicities.

Common Side Effects: - Nausea or vomiting - Loss of appetite - Headache - Diarrhea - Metallic taste in the mouth - Discoloration of urine (yellow‑brown)

Serious or Rare Side Effects: - Pulmonary toxicity (interstitial pneumonitis or fibrosis) - Hepatic injury (hepatitis or jaundice) - Severe allergic reactions (anaphylaxis, Stevens‑Johnson syndrome) - Hemolytic anemia, especially in patients with G6PD deficiency - Peripheral neuropathy - Acute kidney injury

Before prescribing Nitrofurantoïne Mc Viatris, clinicians should consider several safety aspects.

Assess renal function: contraindicated in severe renal impairment (eGFR <30 mL/min). Avoid in patients with known hypersensitivity to nitrofurantoin or other nitrofurans. Monitor for pulmonary symptoms: discontinue if cough, dyspnea, or fever develop. Use caution in patients with liver disease or a history of hepatic dysfunction. Store at ambient temperature: keep in the original packaging, protect from moisture and light.

Nitrofurantoin can interact with other medicines, affecting its absorption or toxicity profile.

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: significantly reduce nitrofurantoin absorption. - Probenecid: may increase nitrofurantoin plasma concentrations and risk of toxicity. - Warfarin: nitrofurantoin can potentiate anticoagulant effects, requiring closer INR monitoring.

Moderate Interactions (Monitor Closely): - Fluoroquinolones: combined use may increase the risk of tendonitis or tendon rupture. - Oral hypoglycemic agents: nitrofurantoin may alter glucose control, necessitating blood sugar monitoring.
