Can Progesterone Prevent Miscarriage in the First Trimester?
First trimester bleeding is very common and very stressful. For decades, clinicians and researchers have looked for ways to prevent miscarriage and other pregnancy complications. A recent trial called the PREEMPT trial, investigated whether progesterone can prevent miscarriage in the first trimester. Specifically, whether vaginal progesterone supplementation could effectively prevent miscarriage or preterm delivery in patients with first-trimester vaginal bleeding.
Can Progesterone Prevent Miscarriage in the First Trimester?
This study was a multi-center, double-blind, randomized trial conducted between 2016 and 2020. Patients who presented with first-trimester vaginal bleeding were randomized to either vaginal progesterone or a placebo that was administered from the start of bleeding until 34 weeks gestation. Unfortunately, the outcomes were the same in both groups, and vaginal progesterone did not prevent miscarriage or preterm delivery.
