Jakafi Pregnancy Warnings
In animal studies, treatment-related malformations were not observed with administration to pregnant rats and rabbits during the period of organogenesis, but adverse developmental outcomes such as decreased fetal weights (rats and rabbits) and increased late resorptions (rabbits) were observed at maternally toxic doses. There are no controlled data in human pregnancy.
AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.
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 to the fetus.
AU TGA pregnancy category: C
