Gifaxin 400 Tablet contains Rifaximin 400 mg, a broad-spectrum, non-absorbable antibiotic primarily used to treat gastrointestinal infections caused by susceptible bacteria. Rifaximin acts by inhibiting bacterial RNA synthesis through binding to the beta-subunit of bacterial DNA-dependent RNA polymerase, leading to the suppression of bacterial growth. Due to its minimal systemic absorption, Gifaxin 400 is effective locally within the gastrointestinal tract, making it suitable for conditions such as traveler's diarrhea caused by non-invasive strains of Escherichia coli, hepatic encephalopathy prevention by reducing gut ammonia-producing bacteria, and irritable bowel syndrome with diarrhea (IBS-D). The medication is generally well-tolerated, with a low incidence of systemic side effects. It is contraindicated in patients with known hypersensitivity to rifaximin or any rifamycin derivatives. Dosage and duration of therapy should be determined based on the specific indication and clinical response. Caution is advised in patients with severe hepatic impairment. Gifaxin 400 should be used under medical supervision, and patients should complete the prescribed course to prevent bacterial resistance. It is important to monitor for any adverse reactions and report them promptly to a healthcare professional.
