Tildrakizumab Pregnancy Warnings

Animal studies have revealed no evidence of embryotoxicity or teratogenicity. There are no controlled data in human pregnancy. It is not known whether this drug can cause fetal harm or adversely affect reproductive capacity in humans.

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.

This drug should be used during pregnancy only if the benefit outweighs the risk.

US FDA pregnancy category: Not assigned.

Risk Summary: Limited available data with use in pregnant women are insufficient to inform a drug associated risk of adverse developmental outcomes. Human IgG is known to cross the placental barrier; therefore, this drug may be transferred from the mother to the fetus.

Comments:
-Adequate methods of contraception should be encouraged.
