Does Rifaximin cure SIBO permanently?

While Rifaximin is highly effective at clearing small intestinal bacterial overgrowth, it does not cure SIBO permanently on its own. SIBO is a secondary condition, meaning it is always caused by an underlying motility failure, structural issue, or digestive deficiency. Clinical trials show that without addressing these fundamental dysfunctions or implementing a prokinetic agent post-treatment, up to 40% of patients experience a relapse within 3 to 6 months of finishing antibiotics. Lasting eradication requires identifying the specific trigger that allowed the bacteria to accumulate, such as low stomach acid or nerve damage from food poisoning. For a comprehensive strategy to identify your triggers and prevent relapse, read our guide on [SIBO root causes](/sibo-root-causes).
