Xifaxan is the brand name of the prescription drug rifaximin, which is used to treat travelers' diarrhea that's caused by Escherichia coli (E. coli).

The drug is also used to prevent a condition known as hepatic encephalopathy, which occurs when your liver doesn't work normally.

It's sometimes also given as a treatment for irritable bowel syndrome (IBS).

Xifaxan is an antibiotic that works by killing bacteria and preventing their growth.

The medicine is used to treat bacterial infections in the intestines only. It passes through the stomach and intestines without being absorbed into the bloodstream.

The Food and Drug Administration (FDA) approved Xifaxan in 2004. It's manufactured by Salix Pharmaceuticals.
