Cephradine and Breastfeeding

Summary of use during lactation

Limited information indicates cephradine produces low levels in milk that are not expected to cause adverse effects in breastfed infants. Occasionally disruption of the infant's gastrointestinal flora, resulting in diarrhea or thrush have been reported with cephalosporins, but these effects have not been adequately evaluated. cephradine is acceptable in nursing mothers.
