RIFACOOL 400, 200, and 550 Mg Tablets contain Rifaximin, an antibiotic used to treat specific gastrointestinal conditions. Rifaximin works by inhibiting bacterial RNA synthesis, targeting gut bacteria without significant absorption into the bloodstream, making it effective for intestinal infections. It is commonly prescribed to treat traveler’s diarrhea, caused by certain strains of E. coli, and for managing irritable bowel syndrome (IBS) with diarrhea. Additionally, Rifaximin 550 mg is used to reduce the risk of hepatic encephalopathy in patients with liver disease by lowering the amount of ammonia-producing bacteria in the gut. RIFACOOL is generally well-tolerated, but common side effects may include nausea, bloating, or headache. It’s essential to follow the prescribed dosage and complete the full course of treatment, even if symptoms improve, to avoid bacterial resistance.
