Cervidil (generic: dinoprostone) is a prescription medication used to soften and dilate the cervix (known medically as cervical ripening) for the induction of labor in pregnant women who are at or near term. This medication is a synthetic version of prostaglandin E2, a naturally occuring hormone important for preparing the cervix during labor.

Cervidil comes as a vaginal insert to be placed on the cervix. It is designed to release the medication slowly over 12 hours and is removed upon active labor onset or 12 hours after insertion.

Common side effects include strong uterine contractions.
