Uses
This medication is used to help prepare your cervix (the lower opening of the womb) for labor and delivery. It is used in women who are having a normal pregnancy and who are at or near their delivery due date. Dinoprostone is a natural substance that your body makes in preparation for labor. It relaxes and softens your cervix (cervical ripening) to allow the baby to pass through the birth canal during delivery.
How To Use
This drug is inserted high in your vagina next to the cervix by a health care professional. You will be lying down while the medication is placed, and you will usually need to continue lying down for 2 hours after insertion. The health care professional will tell you when you can get up and walk around.
This medication should only be used in a hospital setting with trained medical care available. You will be monitored for changes in your cervix, for signs of active labor (such as water breaking, strong sustained contractions), and for your baby's condition. The health care professional will remove the insert if there are side effects, after 12 hours, or when it is no longer needed. The drug's effects wear off quickly after the insert is removed.
Side Effects
Side effects such as fever, nausea, vomiting, diarrhea, or abdominal pain are uncommon and usually mild. If any of these effects last or get worse, tell your doctor or midwife right away.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
