Abstract

Background: In an attempt to improve efficacy for women who desire medical management of early pregnancy failure (EPF), we studied the efficacy and acceptability of mifepristone 200 mg, orally (po), followed 24 h later by misoprostol 800 μg, vaginally (pv), for the treatment of EPF. Methods: We enrolled 30 women with EPF in this pilot clinical trial. All women used misoprostol 800 μg, pv, 24 h after ingesting 200 mg mifepristone. Follow-up evaluations with transvaginal ultrasonography occurred at 24 h and 1 week after treatment. Participants were offered a repeat dose of misoprostol if the pregnancy had not been expelled at the first follow-up. Results: The expulsion rate with one dose of misoprostol was 90% (95% CI=79-100%). The overall success rate of the treatment was 93% (95% CI=84-100%). Conclusion: This regimen of mifepristone followed by vaginal misoprostol appears to be an efficacious and acceptable treatment for EPF and may have improved results over a single dose of misoprostol alone.
