Summary
In this study the investigators aim to compare the efficacy of neomycin to a combination of rifaximin and neomycin in the treatment of C-IBS subjects with methane on their breath test. This study will be conducted in collaboration with Dr. John DiBaise at the Mayo Clinic in Scottsdale, AZ and Dr. Satish Rao in Georgia Regents University in Augusta, GA.
