Antibiotics such as Xifaxan will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment. This results in the blockage of the translocation step that normally follows the formation of the first phosphodiester bond, which occurs in the transcription process. This in turn results in a reduction of bacteria populations, including gas producing bacteria, which may reduce mucosal inflammation, epithelial dysfunction and visceral hypersensitivity.

Xifaxan has broad spectrum antibacterial properties against both gram positive and gram negative anaerobic and aerobic bacteria. As a result of bile acid solubility, its antibacterial action is limited mostly to the small intestine and less so the colon.

A resetting of the bacteria composition has also been suggested as a possible mechanism of action for relief of IBS symptoms. Additionally, Xifaxan may have a direct anti-inflammatory effect on gut mucosa via modulation of the pregnane X receptor.

A two-week course of the antibiotic rifaximin Xifaxan helps to relieve the symptoms of irritable bowel syndrome IBS , and the relief lasts up to 10 weeks after stopping the medication, according to new research.
