Is Meropenem compatible with breastfeeding? Do we have alternatives for Meropenem?


December 8, 2017 (Very Low Risk)

Antibacterial carbapenem beta-lactam with indications similar to imipenem.
Intravenous administration every 8 hours.

It is excreted in breast milk in a clinically insignificant amount (Sauberan 2012) and no problems have been observed in infants whose mothers took it (Festini 2004).

Authorized pediatric use in infants and newborns.

It is considered by experts to be compatible with breastfeeding (Rowe 2013).

The possible negativity of cultures in febrile infants whose mothers take antibiotics should be taken into account, as well as the possibility of gastroenteritis due to altered intestinal flora (Benyamini 2005, Ito 1993, Kafetzis 1981).


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