藥物流產(英語:medical abortion,也稱為藥物墮胎(英語:medication abortion,non-surgical abortion),是指使用藥物進行流產[1],是子宮抽吸或擴張和清宮等手術流產的替代方法。[2][3][1]藥物流產在大多數地方都較為常見,包括歐洲、印度、中國大陸和美國等。[4] [5]

典型的建議是使用兩種藥物,先用米非司酮,再用米索前列醇[3]儘管還有其他選擇,當沒有米非司酮時,可以單獨使用米索前列醇[3] [2]妊娠初期,可以安全地在家中服用這些藥物。[1]妊娠中期,建議在醫院內使用。[3]

藥物流產在各個孕周內都是安全有效的,包括妊娠中期(13至24周)。[3]有部分證據支持在妊娠晚期使用。[6]副作用通常包括陰道出血子宮痙攣噁心和腹瀉。[2]它對精神健康問題乳腺癌不孕症的風險不造成影響。[1]在美國,母親的死亡率比分娩死亡率低14倍;需要住院、輸血或手術的人數不到千分之四。[7]

藥物流產於20世紀70年代開始使用。[2]2020年,美國進行了超過50萬次藥物流產。[8]世界衛生組織建議所有婦女和女孩都能獲得藥物流產,以減少不安全墮胎及其導致的死亡率。[9]截至2023年,在美國這些藥物的成本可能超過500美元;儘管一些慈善機構可能會免費或以低成本提供這些藥物。[10] [11] [12]在加拿大,加拿大人可以享受醫療保險。 [13]截至2018年,在中低收入國家,費用從4美元到36美元不等。[14]藥物流產不應與緊急避孕藥(事後避孕藥)混淆,後者是在性交後不久立即服用以防止懷孕。[15]
