How it works

From this product’s own US prescribing label.

Progesterone is a naturally occurring steroid that is secreted by the ovary, placenta, and adrenal gland.
In the presence of adequate estrogen, progesterone transforms a proliferative endometrium into a secretory endometrium.

How the body breaks it down

Progesterone is metabolized primarily by the liver largely to pregnanediols and pregnanolones.

How it leaves the body

Progesterone metabolites that are excreted in the bile may be deconjugated and may be further metabolized in the gut via reduction, dehydroxylation, and epimerization.

Pregnancy and breastfeeding

Progesterone vaginal insert has been used to support embryo implantation and maintain clinical pregnancy in one clinical study. The live birth outcomes of these pregnancies were as follows:
Among the 404 subjects treated with progesterone vaginal insert twice daily, 143 subjects had livebirths consisting of 85 singletons, 56 twins, and 2 triplets. In this treatment group, 13 subjects had a spontaneous abortion, 1 subject had an ectopic pregnancy, and 7 subjects reported fetal birth defects (3.4% based on 203 livebirths).
Among the 404 subjects treated with progesterone vaginal insert three times daily, 155 subjects had livebirths consisting of 91 singletons, 60 twins, and 4 triplets. In this treatment group, 22 subjects had a spontaneous abortion, 4 subjects had an ectopic pregnancy, and 7 subjects reported fetal birth defects (3.1% based on 223 livebirths). Birth defects reported in the progesterone vaginal insert twice daily group included:
one fetus with a cleft palate and intrauterine growth retardation, one fetus with spina bifida, three fetuses with congenital heart defects, one fetus with an umbilical hernia, and one fetus with an intestinal anomaly. Birth defects reported in the progesterone vaginal insert three times daily group included:
one fetus with an esophageal fistula, one fetus with hypospadias and an underdeveloped right ear, one fetus with Down’s and an atrial septal defect, one fetus with congenital heart anomalies, one fetus with DiGeorge’s syndrome, one fetus with a hand deformity, and one fetus with cleft palate. For additional information on the pharmacology of progesterone vaginal insert and pregnancy outcome information [see Clinical Pharmacology ( 12 ) and Clinical Studies Sections ( 14 )] .
Detectable amounts of progesterone have been identified in the milk of nursing mothers. The effect of this on the nursing infant has not been determined.
