Medicine information
Uses & overview
Rifaximin 400 mg is an intestinal antibiotic belonging to the rifamycin group. It works by inhibiting bacterial RNA synthesis, helping prevent susceptible bacteria from growing. Because rifaximin is minimally absorbed into the bloodstream, its antibacterial activity occurs mainly within the gastrointestinal tract. Healthcare professionals may prescribe rifaximin for certain intestinal infections or other approved gastrointestinal conditions, depending on the patient's diagnosis, local treatment guidelines, and the specific product's authorised indications. It is important to understand that rifaximin does not treat viral infections or every cause of diarrhoea, and the 400 mg strength is not suitable for every patient or condition. Patients searching for Rifaximin 400 mg uses or planning to buy Rifaximin 400 mg online in India should consult a qualified healthcare professional before starting treatment. Your doctor can determine whether an antibiotic is necessary and recommend the appropriate strength and duration. For online medicine purchases in India, select a reputable, licensed pharmacy and verify the manufacturer's details, packaging, product strength, and expiry date. Possible side effects include nausea, abdominal discomfort, headache, and changes in bowel movements. Seek medical attention if you develop severe or persistent diarrhoea, blood in your stools, high fever, or signs of dehydration. Use rifaximin exactly as prescribed and do not share antibiotics with others.
