Best antimicrobials for small intestinal bacterial overgrowth?

Discuss with your MD: Be sure to discuss this with the doctor that diagnosed you with small intestinal bacterial overgrowth. A number of antibiotics will work; which one prescribed depends on your history (drug allergies, intolerances) and the specific situation.

Maybe temporary fix: If you have ibs due to sibo (small intestinal bacterial overgrowth)--antibiotics like xifaxan (rifaximin) may help. Sibo may also occur from anatomic variations in the small bowel, altered small bowel motility, or a variety of systemic conditions that prevent permanent cure (e.g. The bacteria just grow back).
