Misoprostol to treat missed abortion in the first trimester

Abstract

Missed abortion in the first trimester is characterized by the arrest of embryonic or fetal development. The cervix is closed and there is no or only slight bleeding. Ultrasound examination shows an empty gestational sac or an embryo/fetus without cardiac activity. Based on a review of the published literature a single dose of 800 μg vaginal misoprostol may be offered as an effective, safe, and acceptable alternative to the traditional surgical treatment for this indication. Alternatively, 600 μg misoprostol can be administered sublingually. After administration of misoprostol, hospitalization is not necessary and the time to expulsion varies considerably. Bleeding may last for more than 14 days with additional days of light bleeding or spotting. The woman should be advised to contact a provider in case of heavy bleeding or signs of infection. A follow-up is recommended after 1 to 2 weeks. © 2007 International Federation of Gynecology and Obstetrics.
