Febuxostat Pregnancy Warnings

Use is not recommended during pregnancy unless the benefit outweighs the risk to the fetus.
-Some experts recommend: Use should be avoided.

AU TGA pregnancy category: B1
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.

Animal models have revealed evidence of neonatal mortality and reductions in neonatal weight gain when rats were given oral doses up to 40 times the human plasma exposure (80 mg/day) during organogenesis through lactation. Limited human exposure data have not indicated adverse effects on the health of the fetus or newborn infant. There are no controlled data in human pregnancy.

AU TGA pregnancy category B1: 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 have not shown 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.
