Max Misoprostol Total Dose For Ripening?

The earliest studies of misoprostol’s use in cervical ripening and labor induction were done by South American investigators, who reported their experience using intravaginal misoprostol. This was published in the Lancet in 1992. Despite its widespread incorporation into obstetrical practice, there’s still some lack of uniformity in its administration. Is there a cumulative maximum dose allowed for cervical ripening? What about time… is there a maximal amount of time in which misoprostol can be used? Is that 12 hours, 18 hours, 24 hours? In this episode we will review important misoprostol’s FDA label information, summarize position statement from the ACOG and AWHONN, and discuss issues with “scoring” the 100mcg tablet to give a 25mcg dose. And of course, we will summarize the important peer-reviewed data regarding “maximum vaginal cumulative doses” of this medication for cervical ripening/labor induction.
