Methods: 82 patients with intrauterine uterus after induced abortion treated in our hospital from April 2012 to April 2013 were randomly divided into control group and observation group, 41 cases each. The control group was given oral mifepristone 100mg / d; the observation group was given oral mifepristone 50mg / d for 14 consecutive days. The therapeutic effect was observed in two groups and the incidence of adverse reactions was compared. Results: After treatment, there was no significant difference in the total effective rate between two groups (P> 0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group (P <0.05). CONCLUSION: Oral mifepristone treatment of intrauterine abortion after induced abortion can be more satisfactory clinical treatment, high doses of medication will increase the incidence of adverse reactions, it is worth the clinical attention.
