Cervidil
Cervidil (dinoprostone) is a small vaginal insert used during pregnancy to help induce (start) labor. The insert is placed in the vagina by your labor and delivery team in the hospital. It works by slowly releasing medication to soften your cervix, which helps prepare your body to give birth. Common side effects include more frequent or longer contractions.

Pharmacist tips for Cervidil (dinoprostone)
- Cervidil (dinoprostone) is placed in your vagina by the labor and delivery team while you’re in the hospital.
- Your care team might use a small amount of water-based lubricant when placing Cervidil (dinoprostone). They'll use just enough lubricant, since too much can block the insert from releasing the medication.
- After Cervidil (dinoprostone) is placed, you’ll need to lie down for at least 2 hours. This helps keep the insert in place.
- If you need to use the bathroom after Cervidil (dinoprostone) is placed, gently blot instead of wiping. This helps keep the insert from moving.
- Tell your care team right away if you feel discomfort, irritation, or think Cervidil (dinoprostone) has moved out of place.
- Cervidil (dinoprostone) can cause contractions that are very frequent or last a long time. Your care team will monitor you and your baby closely to make sure blood flow to the baby stays safe.
Risks and warnings for Cervidil (dinoprostone)
Cervidil (dinoprostone) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Blood-clotting problem
- Risk factors: Age 30 years and older | Complications during pregnancy | More than 40 weeks pregnant before labor
Labor induction, whether it happens naturally or with medications like Cervidil (dinoprostone), can raise your risk of a rare but serious blood-clotting problem called disseminated intravascular coagulation (DIC) right after delivery. DIC can cause severe bleeding in different parts of your body. Your risk is higher if you’re 30 or older, have pregnancy complications, or are more than 40 weeks pregnant. Your care team will monitor you closely after birth and give treatment right away if needed.
Amniotic fluid embolism syndrome
Cervidil (dinoprostone) can rarely cause a very serious condition called amniotic fluid embolism syndrome during or shortly after childbirth. This happens when amniotic fluid enters the mother’s bloodstream. It is a medical emergency that needs fast treatment. Your care team will watch closely for warning signs like seizures, loss of consciousness, low blood pressure, low oxygen levels, trouble breathing, or heavy bleeding.
Frequent or very strong contractions
Cervidil (dinoprostone) can cause very frequent or very strong contractions, with or without changes in your baby's heart rate. While Cervidil (dinoprostone) is in place, your care team will closely monitor your contractions, your baby’s heart rate, and how your cervix is changing. And it will be removed right away if contractions become too strong or too frequent, if your baby shows signs of stress, or if active labor begins.
Cervidil (dinoprostone) shouldn't be used if long or strong contractions could be unsafe for you or your baby. This includes people who’ve had a previous C-section or major surgery on the uterus, because of a higher risk of serious complications.
Glaucoma
Prostaglandins like Cervidil (dinoprostone) can raise pressure inside your eyes and make your pupils smaller. If you have glaucoma, this medication can worsen your eye condition. Tell your OB-GYN if you have glaucoma so they can decide whether a different medication would be safer to use to prepare your cervix and start labor.
Cervidil (dinoprostone) dosage
Typical dosage for Cervidil (dinoprostone)
Cervidil (dinoprostone) is given by a healthcare professional in the hospital.
The typical dose is one 10 mg insert placed in the vagina once and left in place for up to 12 hours. The insert slowly releases 0.3 mg of medication each hour.
Interactions between Cervidil (dinoprostone) and other drugs
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
