Risk summary: There are no data on the developmental risk associated with use during human pregnancy; based on animal data, this drug may cause fetal harm.

Animal reproduction studies have revealed evidence of increased malformations and post-implantation loss and resorptions after subcutaneous administration at exposures greater than those used clinically. There are no controlled data in human 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.
