Simple antibiotic pill may protect mothers and babies during induced labor
NCT ID NCT06543290
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether giving a single 2-gram dose of azithromycin before starting labor induction can lower the risk of infections in both the mother and newborn. Researchers plan to enroll 400 pregnant women in their third trimester who are scheduled for labor induction. Half will receive the antibiotic and half a placebo, and the rates of infections like chorioamnionitis will be compared.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- azithromycin
- What this could lead to
- If it works, this could provide a simple, low-cost way to prevent serious infections during childbirth.
- What could go wrong
- This is an early Phase 1 trial, so the results are uncertain. The drug may not reduce infections as hoped, and side effects are possible.
