NCT ID NCT05695352

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This completed phase 2 study tested whether taking levonorgestrel (the hormone in Plan B) plus meloxicam (an anti-inflammatory) can delay ovulation by 7 days in healthy women. Nineteen women aged 18-40 took either placebo or the drug combo around ovulation. The goal was to see if the combo could give a longer window to prevent pregnancy. Results are pending.

What this could lead to
