Nifuroksazyd Gedeon Richter (Nifuroxazide)

Nifuroxazide is used to manage infections of the intestinal tract and related diarrheal conditions.

• Acute diarrhea: reduces stool frequency and improves stool consistency.
• Enteritis: alleviates inflammation and bacterial overgrowth in the gut.
• Intestinal bacterial infections: eradicates susceptible pathogens within the intestinal lumen.

• Nifuroxazide is reduced by bacterial nitroreductases to reactive metabolites that bind to bacterial DNA and interfere with protein synthesis. This dual action damages bacterial genetic material and halts essential protein production, resulting in bacteriostatic or bactericidal activity confined to the intestinal lumen where the drug remains largely unabsorbed.

Adverse reactions are generally mild and limited to the gastrointestinal tract.

Common Side Effects

• Nausea: mild discomfort after oral intake.
• Abdominal cramps: intermittent stomach pain.
• Flatulence: increased intestinal gas.
• Altered taste: temporary metallic or bitter sensation.
• Mild rash: localized skin irritation.

Serious or Rare Side Effects

• Severe allergic reaction: hives, swelling, or difficulty breathing.
• Persistent diarrhea: worsening of symptoms despite therapy.
• Hepatic dysfunction: abnormal liver enzyme levels.
• Hematologic changes: unexplained bruising or bleeding.
• Clostridioides difficile infection: severe colitis following disruption of normal flora.

Before using Nifuroxazide, consider the following safety measures.

• Pregnancy: consult a healthcare professional; safety data are limited.
• Breastfeeding: discuss potential exposure with a physician.
• Pediatric use: dosage and duration should be determined by a prescriber.
• Renal or hepatic impairment: monitor closely if underlying disease exists.
• Allergies: avoid if known hypersensitivity to nitrofurans.
• Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Nifuroxazide may interact with other agents that affect gut flora or absorption.

Major Interactions (Avoid)

• Broad‑spectrum antibiotics: may reduce efficacy by altering intestinal bacteria.
• Antacids containing aluminum or magnesium: can interfere with drug dissolution.

Moderate Interactions (Monitor Closely)

• Probiotics: may modify therapeutic effect, monitor clinical response.
• Antidiarrheal agents (e.g., loperamide): could mask symptoms, assess need.
• Oral contraceptives: no direct interaction, but monitor for gastrointestinal disturbances that could affect absorption.
