Summary of Use during Lactation
Rifaximin is poorly absorbed orally and used only for gastrointestinal infections. It is not likely to reach the breastmilk or bloodstream of the infant or cause any adverse effects in breastfed infants after maternal use. However, no published experience exists with rifaximin during breastfeeding; therefore, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
