Episode notes

The ACOG 2025 guideline specifically recommends either oral or vaginal misoprostol for cervical ripening; it does not include buccal administration among its endorsed routes. With the rising rates of both obesity and labor induction, understanding the optimal agents for induction in obese patients is crucial. In a new study released ahead of print on March 4, 2026, in the AJOG, investigators from Indianapolis released findings from a secondary analysis of the IMPROVE trial (2019, AJOG) looking at the effect of obesity on buccal vs vaginal doses of misoprostol for cervical ripening. Listen in for details.
