Sleep hormone melatonin tested as painkiller for C-Section moms
NCT ID NCT07380568
First seen Jun 24, 2026 · Last updated Jul 15, 2026 · Updated 4 times
Summary
This study tests whether taking melatonin before a planned C-section can lower pain afterward. Sixty women will receive either 5 mg, 10 mg, or a placebo pill one hour before surgery. Researchers will track pain levels, how soon they need extra pain relief, and any side effects over 24 hours.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Melatonin
- What this could lead to
- If it works, this could offer a simple, low-cost way to reduce pain after C-section and cut down on opioid use.
- What could go wrong
- This is a small, early-phase trial with only 60 participants. Melatonin may not reduce pain significantly, and side effects like drowsiness or dizziness are possible.
