Cefotaxime Sodium


Safe substance and/or breastfeeding is the best option.

Third-generation cephalosporin for injection or parenteral administration.

Like most cephalosporins for which data are available, excretion occurs in breast milk in very small or undetectable amount and it is clinically insignificant. (Matsuda 1984, Takase 1982, Cho 1982, Yasuda 1982, Kafetzis 1981 & 1980)

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, Rowe 2013, Bar-Oz 2003, Scott 1996, Fulton 1992). American Academy of Pediatrics: medication usually compatible with breastfeeding.(AAP 2001)


We do not have alternatives for Cefotaxime Sodium 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

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.

José María Paricio, founder of e-lactancia.
