Remdesivir Pregnancy Warnings

This drug should not be used during pregnancy unless the benefit outweighs the risk to the fetus.

AU TGA pregnancy category: B2
US FDA pregnancy category: Not assigned.

Risk summary: Insufficient data available on use of this drug in pregnant women to inform a drug-related risk.

-According to some authorities: Patients of childbearing potential must use effective contraception during therapy.
-Pregnant patients hospitalized with coronavirus disease 2019 (COVID-19) are at risk for serious morbidity and mortality.

Animal studies have failed to reveal evidence of embryofetal toxicity. In rats and rabbits, this drug showed no adverse effect on embryofetal development when administered to pregnant animals at systemic exposures (AUC) of the main circulating metabolite of this drug (GS-441524) that were up to 4 times the exposure in humans at the recommended human dose. There are no controlled data in human pregnancy.

AU TGA pregnancy category B2: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals are inadequate or may be lacking, but available data show no evidence of an increased occurrence of fetal damage.

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.
