Safe substance and/or breastfeeding is the best option.

First-generation cephalosporins for oral administration. Actions and uses similar to those of cefalexin.

At latest update no published data on excretion into breast milk were found.

Their short half-life span make unlikely the milk passage of significant amounts into breast milk.

Most cephalosporins are excreted into milk in insignificant amounts from a therapeutic point of view without reported complications in infants.

Cephalosporins are widely used in the Pediatric practice with a good tolerance, even in the neonatal period, so it is very unlikely that in small amounts through milk would be a cause of problems in the infant.

Be aware of the possibility of false negative results of cultures in febrile infants whose mothers are taking antibiotics as well as the possibility of gastroenteritis (Ito 1993) by altering the intestinal flora.


  • Cefalotin Sodium (Safe substance and/or breastfeeding is the best option.)
  • Cephalexin (Safe substance and/or breastfeeding is the best option.)

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
