"Adding misoprostol to oxytocin immediately after childbirth did not additionally prevent postpartum hemorrhage and may have increased women's risks for adverse events compared with administering oxytocin alone, according to a new randomized contr"...
For hospital use only
Cervidil (dinoprostone) should be administered only by trained obstetrical personnel in a hospital setting with appropriate obstetrical care facilities.
Women aged 30 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 postpartum disseminated intravascular coagulation. In addition, these factors may further increase the risk associated with labor induction (See ADVERSE REACTIONS, Post-marketing surveillance). 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 period.
The Clinician should be alert that use of dinoprostone may result in inadvertent disruption and subsequent embolization of antigenic tissue causing in rare circumstances the development of Anaphylactoid Syndrome of Pregnancy (Amniotic Fluid Embolism).
Since prostaglandins potentiate the effect of oxytocin, Cervidil (dinoprostone) must be removed before oxytocin administration is initiated and the patient's uterine activity carefully monitored for uterine hyperstimulation. If uterine hyperstimulation is encountered or if labor commences, the vaginal insert should be removed. Cervidil (dinoprostone) should also be removed prior to amniotomy.
Cervidil (dinoprostone) is contraindicated when prolonged contraction of the uterus may be detrimental to fetal safety and uterine integrity. Therefore, Cervidil (dinoprostone) should not be administered to patients with a history of previous cesarean section or uterine surgery given the potential risk for uterine rupture and associated obstetrical complications, including the need for hysterectomy and the occurrence of fetal or neonatal death.
Caution should be exercised in the administration of Cervidil (dinoprostone) for cervical ripening in patients with ruptured membranes, in cases of non-vertex or non-singleton presentation, and in patients with a history of previous uterine hypertony, glaucoma, or a history of childhood asthma, even though there have been no asthma attacks in adulthood.
Uterine activity, fetal status and the progression of cervical dilatation and effacement should be carefully monitored whenever the dinoprostone vaginal insert is in place. With any evidence of uterine hyperstimulation, sustained uterine contractions, fetal distress, or other fetal or maternal adverse reactions, the vaginal insert should be removed.
An increased risk of post-partum disseminated intravascular coagulation has been described in patients whose labor was induced by physiologic means, either with dinoprostone or oxytocin.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term carcinogenicity and fertility studies have not been conducted with Cervidil (dinoprostone) Vaginal Insert. No evidence of mutagenicity has been observed with prostaglandin E2 in the Unscheduled DNA Synthesis Assay, the Micronucleus Test, or Ames Assay.
Teratogenic Effects - Pregnancy Category C
Prostaglandin E2 has produced an increase in skeletal anomalies in rats and rabbits. No effect would be expected clinically, when used as indicated, since Cervidil (dinoprostone) Vaginal Insert is administered after the period of organogenesis. Prostaglandin E2 has been shown to be embryotoxic in rats and rabbits, and any dose that produces sustained increased uterine tone could put the embryo or fetus at risk.
The safety and efficacy of Cervidil (dinoprostone) has been established in women of a reproductive age and women who are pregnant. Although safety and efficacy has not been established in pediatric patients, safety and efficacy are expected to be the same for adolescents.This monograph has been modified to include the generic and brand name in many instances.
