Can Probiotics Prevent Side Effects of Antibiotics?

The Article: Probiotics to Prevent Clostridium difficile Infection in Patients Receiving Antibiotics Joshua Z Goldenberg, ND; Dominik Mertz, MD; Bradley C. Johnston, PhD

A JAMA Clinical Evidence Synopsis summary of Cochrane review article of 31 articles

The Clinical Question: In adults and children prescribed antibiotics, is co-administration of a probiotic associated with a lower risk of symptomatic C. diff infection without an increase in adverse events?

The Evidence: Clinical trials sited: 39 (33 adults, 6 peds) Study years: 1988-2012 Number of patients: 9955 Setting: inpatient, outpatient, and combined Primary outcomes: C. diff infection and adverse events Secondary outcomes: C. diff detection and antibiotic associated diarrhea

The Results: Probiotics lowered risk of C. diff for all comers from 4% to 1.5% with a NNT of 40 to prevent one C. diff infection. NNT did not change significantly when looking at treatment setting, patient age, or probiotic species/dose. NNT for cramping and nausea: 37 NNT for diarrhea: 17

The Takeaway: When co-administered with antibiotics, probiotics are associated with a lower risk of C. diff infection and other common GI side effects. They are considered a cheap and low risk option that should be considered whenever we prescribe antibiotics.
