Rifaximin 400/550 mg is an antibiotic medication used to treat a variety of bacterial infections. It is primarily prescribed for gastrointestinal infections caused by bacteria like Escherichia coli, Salmonella, and Shigella. Rifaximin works by preventing the growth and replication of these harmful bacteria, thereby reducing the severity of the infection.
Rifaximin is available in two strengths: 400 mg and 550 mg. The dosage prescribed by the doctor may depend on the severity of the infection and the age and health of the patient. The medication is typically taken orally with a glass of water, and it can be taken with or without food.
One of the unique features of Rifaximin is that it is not absorbed into the bloodstream and remains in the gut. This makes it a useful option for treating infections that are primarily localized in the gastrointestinal tract. Moreover, Rifaximin has a low risk of causing bacterial resistance, which is a growing concern with other antibiotics.
Rifaximin has been found to be effective in treating various gastrointestinal conditions like traveler’s diarrhea, irritable bowel syndrome (IBS), and hepatic encephalopathy. It has also been used in the treatment of small intestinal bacterial overgrowth (SIBO) and diverticular disease.
In terms of side effects, Rifaximin is generally well-tolerated, and serious side effects are rare. Common side effects include nausea, abdominal pain, and diarrhea. These symptoms usually subside on their own within a few days of starting the medication.

Its unique properties make it a safe and effective option for the treatment of conditions like traveler’s diarrhea, IBS, and hepatic encephalopathy.
