5 Warnings and Precautions

Newly added subsection:

5.4 Embryo-Fetal Toxicity

Based on findings from animal studies and its mechanism of action, ARIMIDEX can cause fetal harm when administered to a pregnant woman. Anastrozole caused embryo-fetal toxicities in rats at maternal exposure that were 9 times the human clinical exposure, based on area under the curve (AUC). In rabbits, anastrozole caused pregnancy failure at doses equal to or greater than 16 times the recommended human dose on a mg/m2 basis. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during therapy with ARIMIDEX and for at least 3 weeks after the last dose.

8 Use in Specific Populations

8.1 Pregnancy

8.2 Lactation

8.3 Females and Males of Reproductive Potential
