Animal data
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
Lactation
There are no data on presence of drug or metabolites in human milk, or effects on breast-fed child or on milk production; because many drugs are excreted in human milk and because of tumorigenicity shown for anastrozole in animal studies, or potential for serious adverse reactions in breast-fed child from treatment, advise lactating women not to breastfeed during treatment and for 2 weeks after last dose
Interactions
Efficacy decreased by oestrogens. Plasma concentrations decreased by tamoxifen.
