After completion of antibiotic therapy with Xifaxan, rectal bleeding may result from irritation of the intestinal mucosa, changes in the intestinal microbiota, or exacerbation of hemorrhoids, especially if constipation or hard stools are present. Xifaxan rarely causes these symptoms, but a change in the bacterial flora can affect intestinal sensitivity. If the bleeding is getting worse or accompanied by other symptoms, such as abdominal pain or diarrhea, it is worth consulting a doctor.
