Infusions of dinoprostone.

Therapeutic termination of pregnancy in missed abortion
Maintenance of patency of ductus arteriosus (before corrective surgery)
Initially: Prepare a sterile solution of dinoprostone in normal saline or 5% dextrose containing 5 micrograms per ml and infuse at 2.5 micrograms per minute for 30 minutes.
If a satisfactory uterine contractility response is produced, maintain infusion rate of 2.5 micrograms per minute. In unsatisfactory uterine contractility response, increase infusion rate to 5 micrograms per minute. If satisfactory uterine activity is not produced after at least 4 hours the rate may be increased to 10 micrograms per minute, maintaining until abortion occurs or the treatment is considered a failure. If significant side effects occur, the rate of infusion should be decreased by 50% or discontinued.
If a constant rate infusion pump is used, a different concentration of solution (e.g 15 micrograms/per ml) may be required, dependent on the type of pump, but the dose rates (micrograms/per minute) should remain the same.
Continuous administration for more than 2 days is not recommended.

Pregnancy: Monitor for disseminated intravascular coagulation postpartum
Discontinue & re-assess patient if uterine hypertonia occurs
Women aged 35 years or older, those with complications during pregnancy and those with a gestational age over 40 weeks have been shown to have an increased risk of post-partum disseminated intravascular coagulation. In addition, these factors may further increase the risk associated with labour induction. Therefore, in these women, use of dinoprostone should be undertaken with caution. Measures should be applied to detect as soon as possible an evolving fibrinolysis in the immediate post-partum phase.
Dinoprostone should not be administered by the intramyometrial route as there is a possible association between this route and cardiac arrest in severely ill patients.
Pregnancy and Lactation
Dinoprostone infusion is used for termination of pregnancy, missed abortion and hydatidiform mole.
Animal studies have shown teratogenic effects. If abortion does not occur or is suspected to be incomplete as a result of prostaglandin therapy (as in spontaneous abortion, where the process is sometimes incomplete), the appropriate treatment for complete evacuation of the pregnant uterus should be instituted in all instances.
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame.

Dinoprostone infusion is excreted in breast milk. This is not expected to be harmful due to the nature in which the product is used.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
