Cefaclor

Compatible

Safe substance and/or breastfeeding is the best option.

Second-generation cephalosporin. Oral administration every 8 hours.

Like most cephalosporins for which data are available, excretion occurs in breast milk in very small amount and it is clinically insignificant. (Takase 1979)

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.

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)

Alternatives

We do not have alternatives for Cefaclor 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.
