Antibiotics vs. placebo for Kids' sinus infections: which works best?

NCT ID NCT07732699

First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time

Summary

This trial tests whether common antibiotics—amoxicillin or amoxicillin-clavulanate—actually reduce symptoms in children aged 2 to 12 with acute sinusitis. About 1,100 children are randomly assigned to one of the two antibiotics or a placebo, and parents track daily symptoms. The goal is to see if antibiotics meaningfully improve recovery and whether factors like allergy or illness severity affect their effectiveness.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
amoxicillin, amoxicillin-clavulanate, or placebo
What this could lead to
If antibiotics prove clearly better than placebo, this could confirm their value for childhood sinus infections and help doctors choose the right one.
What could go wrong
This is a Phase 4 trial, but antibiotics may not work for all children, and some may experience side effects like diarrhea. The placebo group helps clarify true benefit.
