Concurrent Use of Mifepristone and Misoprostol for Early Medical Abortion
Article Outline
Summary
Objective
This study was designed to evaluate the efficacy of using mifepristone and misoprostol concurrently for early medical abortion.
Materials and Methods
A total of 90 women with undesired pregnancies ≤ 49 days' gestation were enrolled. All women concurrently received oral mifepristone 200 mg and vaginal misoprostol 800 mg. Follow-up evaluation with transvaginal ultrasonography was performed 4 days and 2 weeks after treatment.
Results
The complete abortion rate was 97.8% (88/90 women). The mean induction to abortion interval was 5.5 hours. The mean bleeding duration was 11.8 days. Patients found the side effects acceptable and reported a 91.1% (82 patients) satisfaction rate.
Conclusion
Concurrent administration of oral mifepristone and vaginal misoprostol is an efficacious regimen for medical abortion of pregnancies ≤ 49 days of gestation.
