Leuprolide / norethindrone Pregnancy Warnings

Administration of leuprolide acetate for depot suspension at doses of 1/300 to 1/3 the human dose on day 6 of pregnancy in rabbits produced a dose-related increase in major fetal abnormalities. Similar studies in rats failed to demonstrate an increase in fetal malformations. Increased fetal mortality and decreased fetal weights were observed with 2 higher doses in rabbits and with the highest dose of 0.024 mg/kg in rats. There are no controlled data in human pregnancy.

US FDA pregnancy category X: Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.
