Additional Information

Rifaximin is used to treat traveler's diarrhea that is caused by a bacteria called Escherichia coli. It is also used to prevent hepatic encephalopathy, which is a condition that occurs when your liver does not work normally. Rifaximin is an antibiotic that works by killing the bacteria and preventing its growth. However, this medicine will not work for colds, flu, or other virus infections
Rifaximin works differently from other antibiotics because it passes through your stomach and into your intestines without being absorbed into your blood stream. Because rifaximin affects only the intestinal tract, it will not treat infections of other parts of the body.

You should not use take this medication if you are allergic to rifaximin or medications such as rifabutin (Mycobutin), rifampin (Rifater, Rifadin, Rifamate), or rifapentine (Priftin).

Before you take rifaximin, tell your doctor if you have severe liver disease, diarrhea with fever, or diarrhea that is watery or has blood in it.

Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Rifaximin will not treat a viral infection such as the common cold or flu, or any form of diarrhea that is caused by a virus. Call your doctor if your symptoms do not improve after 24 hours, or if they get worse while taking rifaximin. Rifaximin does not treat all bacterial forms of traveler's diarrhea.
