Antibiotic therapy with rifaximin is commonly used, but relapse rates remain high.\n\nThis randomized, placebo-controlled clinical trial aims to evaluate whether supplementation with a multispecies probiotic containing Enterococcus faecium and Bacillus subtilis improves the effectiveness of rifaximin therapy in adult patients with SIBO.\n\nParticipants will be randomly assigned to receive either rifaximin plus the probiotic or rifaximin plus placebo. Clinical assessments will include hydrogen breath testing and evaluation of gastrointestinal symptoms using standardized questionnaires at baseline and during follow-up visits.\n\nThe study is being conducted at a single academic medical center in Poland and is sponsored by Państwowy Instytut Medyczny MSWiA.
