Yes, Zaxine (rifaximin) is effective in treating SIBO. It is a minimally absorbed antibiotic that targets the small intestine. This makes it less likely to cause side effects than other antibiotics.
In clinical trials, rifaximin has been shown to be effective in eradicating SIBO in about 70% of patients. Please consult a health care professional who can provide personalised advice based on your medical history and condition.
