Answer by DrLact: About VX-950 usage in lactation

VX-950 is not marketed in the United States and has not been studied in nursing mothers. Because it must be used with ribavirin and peginterferon alfa, it is not considered a good choice during breastfeeding. When it was marketed, the manufacturer recommended that mothers taking VX-950 not breastfeed their infants.
