药物流产
 |
药物流产（英语：medical abortion，也称为药物堕胎（英语：medication abortion，non-surgical abortion），是指使用药物进行流产[1]，是子宫抽吸或扩张和清宫等手术流产的替代方法。[2][3][1]药物流产在大多数地方都较为常见，包括欧洲、印度、中国大陆和美国等。[4] [5]
典型的建议是使用两种药物，先用米非司酮，再用米索前列醇。[3]尽管还有其他选择，当没有米非司酮时，可以单独使用米索前列醇。[3] [2]在妊娠初期，可以安全地在家中服用这些药物。[1]在妊娠中期，建议在医院内使用。[3]
药物流产在各个孕周内都是安全有效的，包括妊娠中期（13至24周）。[3]有部分证据支持在妊娠晚期使用。[6]副作用通常包括阴道出血，子宫痉挛，恶心和腹泻。[2]它对精神健康问题、乳腺癌或不孕症的风险不造成影响。[1]在美国，母亲的死亡率比分娩死亡率低14倍；需要住院、输血或手术的人数不到千分之四。[7]
药物流产于20世纪70年代开始使用。[2]2020年，美国进行了超过50万次药物流产。[8]世界卫生组织建议所有妇女和女孩都能获得药物流产，以减少不安全堕胎及其导致的死亡率。[9]截至2023年，在美国这些药物的成本可能超过500美元；尽管一些慈善机构可能会免费或以低成本提供这些药物。[10] [11] [12]在加拿大，加拿大人可以享受医疗保险。 [13]截至2018年，在中低收入国家，费用从4美元到36美元不等。[14]药物流产不应与紧急避孕药（事后避孕药）混淆，后者是在性交后不久立即服用以防止怀孕。[15]

The mortality rate for women known to have had a live-born infant is 8.8 per 100,000 live births, which is about 14 times higher than the mortality rate associated with medication abortion.

More than half a million women had medication abortions in 2020 in the United States, and fewer than half of 1 percent experience serious complications, studies show. Medical interventions like hospitalizations or blood transfusions were needed by fewer than 0.4 percent of patients, according to a 2013 review of dozens of studies involving tens of thousands of patients.
