Short answer

**Whether you should receive aducanumab-avwa injection during pregnancy requires a clinician's review because its pregnancy safety is unknown.**

Aducanumab-avwa, also called Aduhelm, is an intravenous treatment for Alzheimer's disease. Available human data cannot establish its risks of birth defects, miscarriage, or other pregnancy complications. Your prescriber and prenatal clinician need to weigh your treatment needs against these unknown risks. If you become pregnant during treatment, call your prescriber and discuss the plan before your next infusion.

Common questions

Can you take Aducanumab-avwa Injection while pregnant?

Aducanumab-avwa injection (Aduhelm) has not been established as safe during pregnancy. There are not enough human data to assess risks of birth defects, miscarriage, or other pregnancy complications. If you are pregnant or planning pregnancy, discuss treatment with your prescriber and prenatal clinician before an infusion. They need to weigh your Alzheimer's treatment needs against the unknown pregnancy risks. If you become pregnant during treatment, call your prescriber promptly and ask how to handle your next dose. An exposure does not by itself establish that your baby was harmed.
