A recent meta-analysis evaluates the efficacy of low-dose mifepristone as an emergency contraceptive compared to other interventions. Beyond its effectiveness in reducing pregnancy rates, its mechanism of action and ability to interfere with endometrial receptivity has reignited the debate surrounding its bioethical implications and the information women receive about its possible effects.
A recent article analyzes the efficacy of low-dose mifepristone as an emergency (postcoital) contraceptive.
The paper, authored by Shaalini Ramanadhan et al. from Oregon Health and Science University (USA), was published in the Cochrane Database of Systematic Reviews, 2026 (Issue 9. Art. No.: CD016275).
It examines 87 clinical trials conducted over the last three decades, with data from approximately 36,000 women of reproductive age.
The study evaluates the effectiveness, safety, side effects, and acceptability of mifepristone compared to other emergency contraceptive measures--specifically oral regimens (levonorgestrel, the Yuzpe method, and ulipristal acetate) and copper or levonorgestrel intrauterine devices (IUDs)--in reproductive-age women within 5 days of unprotected intercourse.
