Summary

This trial is testing whether giving a certain antibiotic to pregnant women in their third trimester during labor induction can help reduce infections in both the mother and the baby.

Who is the study for?
This trial is for pregnant women in their third trimester (28 weeks or more) who are undergoing labor induction. Participants should be aged 18-45, have a single pregnancy with no complications that would prevent vaginal delivery, and can give informed consent. Women with recent antibiotic use, active infections, substance abuse issues, or inability to understand English or Spanish are excluded.
What is being tested?
The study tests if taking a one-time dose of 2 grams of Azithromycin before inducing labor can reduce maternal and neonatal infections. It's a double-blind trial meaning neither the participants nor the researchers know who gets the real medicine versus a placebo.
What are the potential side effects?
Azithromycin may cause side effects like nausea, vomiting, diarrhea, stomach pain and could potentially lead to allergic reactions. The risk of yeast infections might also increase due to disturbance in natural bacterial balance.
