C16H17N3O5S,H2O

Compatible

Safe substance and/or breastfeeding is the best option.

It is a First generation Cephalosporin.

Like other Cephalosporins, Cefadroxil is excreted into the breast milk in clinically non-significant amounts. (Matsuda 1984, Kafetzis 1981, Takase 1979 )

Although rare, the possibility of transient gastroenteritis due to alteration of the intestinal flora in infants whose mothers take antibiotics should be taken into account. (Ito 1993)

Expert authors consider the use of this medication to be compatible during breastfeeding (Hale, LactMed, Briggs 2015, Bar-Oz 2003, Fulton 1992). American Academy of Pediatrics: medication usually compatible with breastfeeding.(AAP 2001)

Alternatives

We do not have alternatives for C16H17N3O5S,H2O since it is relatively safe.

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.

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