Emergency contraception (EC) is a way to significantly reduce the chance of becoming pregnant after an episode of unprotected intercourse. Considerable data support the safety of all available and emerging options for EC. Areas covered: This review presents a comprehensive summary of the literature regarding the safety of EC as well as directions for further study. PubMed was searched for all relevant studies published prior to June 2017. Expertopinion: All available methods of EC (i.e., ulipristal acetate pills, levonorgestrel pills, and the copper-IUD), carry only mild side effects and serious adverse events are essentially unknown. The copper IUD has the highest efficacy of EC methods. Given the excellent safety profiles of mifepristone and the levonorgestrel IUD, research is ongoing related to use of these products for EC.
紧急避孕（EC）是一种在无保护性交后显著降低怀孕几率的方法。大量数据支持所有现有及新出现的紧急避孕方法的安全性。涵盖领域：本综述全面总结了关于紧急避孕安全性的文献以及进一步研究的方向。检索了PubMed数据库中2017年6月之前发表的所有相关研究。专家观点：所有现有的紧急避孕方法（即醋酸乌利司他片、左炔诺孕酮片和铜宫内节育器）仅伴有轻微副作用，基本上不存在严重不良事件。铜宫内节育器是紧急避孕方法中效果最佳的。鉴于米非司酮和左炔诺孕酮宫内节育器具有出色的安全性，有关将这些产品用于紧急避孕的研究正在进行。
