Current guideline recommendations and pooled comparative evidence support both misoprostol and dinoprostone as effective options for cervical ripening and labor induction in term, singleton pregnancies with intact membranes, with misoprostol administered orally or vaginally and dinoprostone available as a vaginal gel or sustained-release vaginal insert. Across multiple analyses, rates of vaginal delivery, cesarean delivery, and key neonatal outcomes such as low Apgar scores and neonatal inten...
A 2025 Clinical Practice Guideline from the American College of Obstetricians and Gynecologists (ACOG) extensively evaluates contemporary methods for cervical ripening in term, singleton, vertex pregnancies with intact membranes. The panel highlighted that commonly used pharmacologic agents for cervical ripening include misoprostol, a prostaglandin E1 analogue, and dinoprostone, a prostaglandin E2 preparation. Both are recommended options, with oral or vaginal misoprostol supported by strong recommendations and high quality evidence, and vaginal dinoprostone supported by strong recommendations with moderate quality evidence. Misoprostol may be administered orally or vaginally in a range of dosing regimens, whereas dinoprostone is available as a vaginal gel or a 10 mg vaginal insert. Misoprostol is contraindicated in patients with a history of uterine surgery, including cesarean delivery, because of the risk of uterine rupture, and selection of any agent should consider patient chara...
