Category N/ANote that the FDA has deprecated the use of pregnancy categories, so for some medications, this information isn’t available. We still think it’s useful to list historical info, however, given what a common proxy this has been in the past.

Taking Elbasvir While Breastfeeding
What are recommendations for lactation if you're taking Elbasvir?
Elbasvir has not been studied in nursing mothers being treated for hepatitis C infection. Because it is greater than 99.9% bound to maternal plasma proteins, amounts in breastmilk are likely to be very low. Some sources recommend against breastfeeding when elbasvir is used with ribavirin. Hepatitis C is not transmitted through breastmilk[1][2] and breastmilk has been shown to inactivate hepatitis C virus (HCV).[3][4] However, the Centers for Disease Control recommends that mothers with HCV infection should consider abstaining from breastfeeding if their nipples are cracked or bleeding. It is not clear if this warning would apply to mothers who are being treated for hepatitis C. Infants born to mothers with HCV infection should be tested for HCV infection; because maternal antibody is present for the first 18 months of life and before the infant mounts an immunologic response, nucleic acid testing is recommended.[1][2]
