Society of Family Planning Clinical Recommendation: Medication abortion between 14 0/7 and 27 6/7 weeks of gestation : Jointly developed with the Society for Maternal-Fetal Medicine - 10/10/23
Résumé |
The objective of this Clinical Recommendation is to review relevant literature and provide evidence-based recommendations for medication abortion between 14 0/7 and 27 6/7 weeks of gestation, with a focus on mifepristone-misoprostol and misoprostol-only regimens. We systematically reviewed PubMed articles published between 2008 and 2022 and reviewed reference lists of included articles to identify additional publications. See Search Strategy for more details. Several randomized trials of medication abortion between 14 0/7 and 27 6/7 weeks of gestation demonstrate that mifepristone 200 mg orally before misoprostol increases effectiveness (complete abortion at 24 or 48 hours) compared to misoprostol only. Studies continue to evaluate different doses, routes, and dosing intervals for misoprostol. If mifepristone is unavailable, several misoprostol regimens with individual doses of at least 200 mcg or more are effective. Adjunctive osmotic dilators are of limited benefit. It is important to individualize care, with consideration to reducing misoprostol dose in low-resource settings or at 24 0/7 weeks of gestation or later (or equivalent uterine size). Misoprostol in the setting of two or more previous cesarean sections is associated with increased risk of uterine rupture compared to one or none, but risk remains low. Most contraceptives can be started during or immediately following abortion. Appropriately trained and credentialed advanced practice clinicians can provide medication abortion between 14 0/7 and 27 6/7 weeks of gestation with appropriate backup within the confines of local regulations and licensure.
