Blood thinner showdown: which drug best prevents Post-Delivery clots?
NCT ID NCT01588171
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study compared two blood-thinning drugs, Bemiparin and Enoxaparin, to prevent venous thromboembolism (dangerous blood clots) in 7020 women after vaginal or cesarean delivery. All participants had risk factors for clots and received daily injections for up to 7 days after giving birth. The goal was to see which drug worked better and had fewer side effects like bleeding or bruising.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Bemiparin (a blood thinner) and Enoxaparin (a blood thinner)
- What this could lead to
- If successful, this could show that Bemiparin is as good as or better than Enoxaparin at preventing blood clots after childbirth, offering another safe option for new mothers.
- What could go wrong
- This trial is completed, but results may not apply to all women. Both drugs carry risks like bleeding or bruising. The study did not test long-term outcomes.
