Can patients who are pregnant receive Herceptin?
• A: Herceptin can cause fetal harm when administered to a pregnant woman. • Post-marketing reports suggest that Herceptin use during pregnancy increases the risk of oligohydramnios (insufficient amount of amniotic fluid) during the second and third trimester. • Advise women with reproductive potential to use effective contraceptive methods during treatment and for a minimum of six months following Herceptin. • If Herceptin is used during pregnancy or if a woman becomes pregnant while taking Herceptin, she should be apprised of the potential hazard to the fetus. • Pregnant women with breast cancer who are using Herceptin are encouraged to enroll in MotHER, the Herceptin Pregnancy Registry (1-800-690-6720).
