There's limited data, so the safest bet is to discuss the benefits and risks with your OBGYN. Some doctors choose to pause Repatha during pregnancy because the need for lower LDL is weighed against unknown fetal exposure.

Group	Key Consideration	Action
Pregnant/Breastfeeding	Limited safety data	Discuss with OBGYN; possible pause
