A systematic review of 87 trials has concluded that emergency contraception containing mifepristone is more effective at preventing pregnancy than some other common emergency contraceptive pills, including levonorgestrel. The analysis, reported by Medical Xpress, found that mifepristone also came with fewer side effects than the comparator drugs.
The review compared mifepristone against other widely used emergency contraceptives, such as levonorgestrel. Across the included trials, mifepristone consistently outperformed levonorgestrel on both efficacy and tolerability. The findings suggest that mifepristone could be a preferred option where available, though the source does not discuss regulatory status or access issues.
Because this is a single review article, the conclusions rest on the strength of the underlying trials. No conflicting evidence is presented in the source, and the authors of the review appear to support mifepristone's advantage. Further research may still be needed to clarify optimal dosing and real-world effectiveness, but the current evidence points clearly in one direction.
