Cervidil
® (
dinoprostone vaginal insert) is a prescription medication approved to relax and soften the cervix (known as cervical ripening) in preparation for
labor and delivery. It is used in women who are near the time of delivery and have a medical reason that labor must be induced.
The active ingredient in Cervidil is
dinoprostone. Dinoprostone is also available in gel form (
Prepidil®).
Who Makes This Medication?
Cervidil is made by Controlled Therapeutics for Forest Pharmaceuticals, Inc.
Cervidil is a manufactured (synthetic) version of a hormone in the body known as prostaglandin E2. Prostaglandin E2 is naturally secreted by the fetus and placenta during pregnancy, and plays an important role in the steps leading to labor. Importantly, the hormone is involved in cervical ripening, which is when the cervix softens and relaxes to allow passage of the baby during birth.
The Cervidil vaginal insert slowly releases medication over a 12-hour period. The effects of the medication are expected to reverse quickly after the insert is removed.
In one clinical study, 65 percent of women were more likely to go into labor or deliver a baby vaginally within 12 hours of receiving Cervidil, compared with 28 percent of women who received a placebo (a similar product that did not contain any active ingredients). Women who received Cervidil also went into labor about 19.5 hours sooner than women who received a placebo.
