Gentamicin

Very Low Risk for breastfeeding


Compatible.
Not risky for breastfeeding or infant.

Excreted into breast milk in non-significant amount. Harmful effect has not been shown in breastfed infants whose mothers were treated with Gentamicin, except on case of a child who presented with bloody stools while the mother was receiving Gentamicin and Clindamycin.

Low intestinal absorption leads to low or nil concentration in blood serum, with exception of premature infants or early neonatal period in which higher absorption may occur.

Consider the possibility of false negative results of bacterial cultures among febrile breastfed infants whose mothers are treated with Gentamicin. Gastroenteritis due to intestinal flora imbalance is also likely.

When eye drops are used like many other topical ophtalmologic preparations that use low doses with scanty excretion into serum are considered to be compatible with breastfeeding.

The American Academy of Pediatrics rates it compatible with breastfeeding.

The WHO Model List of Essential Medicines 2002 rates it as compatible with breastfeeding.

Alternatives

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

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, 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
