What is Cervidil?

Dinoprostone should be used with strict adherence to recommended dosages and only by medically trained personnel in a hospital setting that can provide immediate intensive care and acute surgical facilities .

Dinoprostone works by causing the cervix to thin and dilate (open) and the uterus to contract (cramp) the way it does during labor.

Dinoprostone may also be used for other purposes as determined by your doctor.

Dinoprostone is to be administered only by or under the immediate care of your doctor.

After dinoprostone is given, you will need to lie down for 10 minutes to 2 hours so that the medicine can be absorbed. The length of time you must remain lying down will depend on what form of the medicine you are using.

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
