Ibs Free 400mg Tablet contains Rifaximin 400mg, a broad-spectrum, non-systemic antibiotic primarily indicated for the treatment of irritable bowel syndrome with diarrhea (IBS-D) and certain gastrointestinal infections. Rifaximin acts by inhibiting bacterial RNA synthesis, thereby reducing the overgrowth of pathogenic bacteria in the intestines without significant systemic absorption. This targeted action helps alleviate symptoms such as abdominal pain, bloating, and diarrhea associated with IBS-D. Ibs Free 400mg is also effective in managing traveler’s diarrhea caused by non-invasive strains of Escherichia coli and in reducing the risk of hepatic encephalopathy recurrence by decreasing gut ammonia-producing bacteria. The recommended dosage and duration of therapy should be strictly followed as per the prescribing physician’s instructions to optimize efficacy and minimize resistance development. Common side effects are generally mild and may include nausea, headache, and abdominal discomfort. Use of Ibs Free 400mg is contraindicated in patients with hypersensitivity to rifaximin or any of its components. Caution is advised in patients with severe hepatic impairment. This medication should be used under medical supervision, and any adverse reactions or lack of therapeutic response should be promptly reported to a healthcare professional.
