What this is

FDA approved Rebyota (Nov 2022) and Vowst (Apr 2023) as first standardized microbiota products for recurrent CDI. DIY FMT has caused deaths from pathogen transmission. Non-CDI indications remain investigational despite hype. Stool banks closing has limited research FMT access.

Mechanism

Infusion of processed donor stool to restore diversity and specific taxa; lyophilized oral capsules (SER-109/Vowst FDA-approved 2023 for CDI) or traditional colonoscopic/enema delivery; mechanism goes beyond any single strain

Dose & route

Rebyota 150 mL enema once; Vowst 4 capsules daily x3 days
