Can a probiotic shield Kids' guts from antibiotic diarrhea?
NCT ID NCT07785206
First seen Aug 25, 2026 · Last updated Aug 26, 2026 · Updated 1 time
Summary
This trial tests whether giving children a probiotic called Saccharomyces boulardii alongside a common antibiotic can prevent diarrhea, a frequent side effect. Children aged 6 months to 5 years with upper respiratory infections will receive either the antibiotic alone or the antibiotic plus the probiotic for 5 days. The study tracks how many children develop diarrhea during treatment and for two weeks after, to see if the probiotic offers protection.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Saccharomyces boulardii, a probiotic supplement, given alongside the antibiotic co-amoxiclav
- What this could lead to
- If effective, adding this probiotic to antibiotic treatment could become a simple, safe way to prevent a common side effect in children.
- What could go wrong
- This is a small, early-stage trial, so results may not apply broadly. The probiotic might not reduce diarrhea risk, and individual responses can vary.
