Is Sprycel safe for pregnant women?

Sprycel (dasatinib) is not recommended during pregnancy because it can harm an unborn baby. Animal studies show fetal harm and human case reports describe birth defects and pregnancy loss. Women who can become pregnant should use effective contraception while taking Sprycel and for 30 days after stopping it. Men taking Sprycel should use effective contraception with their partners for 30 days after stopping the treatment.

Why do animal studies raise concerns?

Animal reproduction studies with dasatinib showed embryo-fetal toxicity at doses below those used in humans. Researchers observed skeletal malformations, reduced fetal weight, and fetal death in rats and rabbits. These findings led the FDA to assign Sprycel a pregnancy category D rating before the current labeling system was revised.
