You could try some over the counter herb-based supplements: Herbal Therapy Is Equivalent to Rifaximin for the Treatment of Small Intestinal Bacterial Overgrowth https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4030608/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4030608/ Subjects with newly diagnosed SIBO by lactulose breath testing (LBT) were given two open-label treatment choices based upon individualized treatment preference; either two 200 mg rifaximin tablets three times daily (TID) or 2 capsules twice daily of the following commercial herbal preparations; Dysbiocide and FC Cidal (Biotics Research Laboratories, Rosenberg, Texas) or Candibactin-AR and Candibactin-BR (Metagenics, Inc, Aliso Viejo, California) for 4 consecutive weeks immediately followed by a repeat LBT. I have been taking Candibactin-AR and Candibactin-BR with my meals and have seen an improvement in my stool consistency (I have recently diagnosed SIBO/Crohn's). I was given the metronidazole for one week and it helped as well, but symptoms came back.
