摘要 目的探讨米非司酮分别用于月经周期二个阶段的避孕效果。方法选择年龄<45岁,无保护性交或避孕措施失败后72 h主动要求采取补救措施220例患者为对象,随机分成二组,单次服用米非司酮10 mg为观察组1,下次月经来潮前10 d内服米非司酮100 mg,48 h后服米索前列醇400μg为观察组2。观察妊娠率、月经来潮时间及不良反应。结果两组患者的妊娠率分别为5.3%和8.6%,差异无显著性(P>0.05),两组患者的下次月经恢复正常的比率,差异也无显著性(P>0.05);药物不良反应发生率中组2比组1明显增高,差异有显著性(P<0.01)。结论米非司酮用于月经周期的不同阶段均有较好的避孕效果,不影响月经,卵泡期用药不良反应少。
