Which drug stops Post-Birth bleeding best? new trial has answers
NCT ID NCT03584854
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two medications, methylergonovine and carboprost, to treat heavy bleeding after a C-section when the first drug (oxytocin) doesn't work. 100 women with postpartum hemorrhage due to a relaxed uterus were randomly assigned to one drug. Doctors measured how well the uterus tightened up. The goal is to find which drug works better to stop dangerous bleeding.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- methylergonovine and carboprost
- What this could lead to
- If one drug works better, it could become the preferred second-line treatment for severe bleeding after childbirth, improving outcomes for mothers.
- What could go wrong
- This is a small, completed trial with only 100 participants, so results may not apply to all women. The drugs also have side effects like high blood pressure or breathing problems.
