Pregnancy & Breastfeeding
8.1 Pregnancy Risk Summary Based on findings in animal studies and mechanism of action, TRELSTAR can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . Expected hormonal changes that occur with TRELSTAR treatment increase the risk for pregnancy loss. In animal developmental and reproductive toxicology studies, daily administration of triptorelin to pregnant rats during the period of organogenesis caused maternal toxicity and embryo-fetal toxicities, including loss of pregnancy, at doses as low as 0.2, 0.8, and 8 times the estimated human daily dose based on body surface area. Advise pregnant patients and females of reproductive potential of the potential risk to the fetus. Data Animal Data Studies in pregnant rats administered triptorelin at doses of 2, 10, and 100 mcg/kg/day (approximately equivalent to 0.2, 0.8, and 8 times the estimated human daily dose based on body surface area) during the period of organogenesis demonstrated maternal toxicity and embryo-fetal toxicities. Embryo-fetal toxicities consisted of pre-implantation loss, increased resorption, and reduced mean number of viable fetuses at the high dose. Teratogenic effects were not observed in viable fetuses in rats or mice. Doses administered to mice were 2, 20, and 200 mcg/kg/day (approximately equivalent to 0.1, 0.7, and 7 times the estimated human daily dose based on body surface area).
