Résumé
Oral fecal microbiota contains live bacterial spores intended to restore the gut flora. Rifaximin acts in the gut lumen and can reduce the engrafting organisms, lowering efficacy. Antibiotic courses should end before the microbiota product is given.
Ce que signifie cette interaction, en termes simples
Microbiota and Rifaximin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Pourquoi elle survient
Luminal antibacterial activity of rifaximin suppresses the administered live bacterial spores and impairs engraftment.
Conduite à tenir
Finish the antibiotic course and allow the interval in the product labeling before giving microbiota. Avoid concurrent rifaximin unless essential.
