Here are some reasons why rifaximin may not work: 1 If the hydrogen and/or methane levels from the breath test were really high, then one round may not cut it and several rounds may be warranted. Unfortunately, insurance varies on how many rounds are covered and the allowable timing between rounds. However, specific herbs can be used after you’ve stopped taking it to help reduce levels. 2 If your SIBO is from predominantly methane producing bacteria, then another drug such as Neomycin will need to be taken at the same time. 3 Other infections may be involved, like small intestinal fungal overgrowth (SIFO) or parasites. 4 Improperly functioning digestive system-this is a big, big category and many factors need to be addressed to set the stage for a healthy digestive tract. For example, researchers have learned that the presence of bile acids greatly increases (100 fold!) the ability of rifaximin to dissolve.3 For those of us without gallbladders-yes, me included, we may need extra digestive support to get maximum effectiveness when taking rifaximin
