-Based on findings from animal studies, female fertility may be compromised by this drug.

Animal studies during organogenesis at doses far below the equivalent recommended human dose revealed embryotoxicity, fetotoxicity, and teratogenicity. Teratogenic effects included severe midline defects, missing digits, and other irreversible malformations. Abortion and complete resorption of fetuses was reported. Skeletal variations were observed when maternal exposure to this drug was below the limit of detection. There are no controlled data in human pregnancy.

AU TGA pregnancy category X: Drugs which have such a high risk of causing permanent damage to the fetus that they should not be used in pregnancy or when there is a possibility of pregnancy.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D and X are being phased out.
