Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

It is a First generation Cephalosporin.

Like other Cephalosporins, Cefadroxil is excreted into the breast milk in clinically non-significant amounts.

Be aware of the possibility of negative results of cultures done to febrile infants whose mothers are on antibiotics.

The American Academy of Pediatrics rates it as usually compatible with breastfeeding.


We do not have alternatives for Cefadroxil since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

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.

Thank you for helping to protect and promote breastfeeding.
