CAS Number: 32986-56-4
Excreted into breast milk in non-significant amount without harm effects observed among breastfed infants of mothers treated with Tobramycin. In addition, a low oral bioavailability renders concentration in the infant's plasma be nil or low. Be aware of false negative results that may be obtained from infants with bacterial cultures when the mother is on antibiotics and higher risk of acute diarrhea by alteration of normal gut flora. When used in eye drops, because of a low dose and topical application with minimal absorption in the serum, it is compatible while breastfeeding.
CAS Number: 32986-56-4
Tobramycin is poorly excreted into breastmilk. Newborn infants apparently absorb small amounts of other aminoglycosides, but serum levels with typical three times per day dosages are far below those attained when treating newborn infections and systemic effects of tobramycin are unlikely. Older infants would be expected to absorb even less tobramycin. Because there is little variability in the milk tobramycin levels during multiple daily dose regimens, timing breastfeeding with respect to the dose is of little or no benefit in reducing infant exposure. Data are not available with single daily dose regimens. Monitor the infant for possible effects on the gastrointestinal flora, such as diarrhea, candidiasis (e.g., thrush, diaper rash) or rarely, blood in the stool indicating possible antibiotic-associated colitis. Maternal use of an ear drop or eye drop that contains tobramycin presents little or no risk for the nursing infant
