Is Kantrex Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Kantrex? Is Kantrex safe for nursing mother and child? Does Kantrex extracts into breast milk? Does Kantrex has any long term or short term side effects on infants? Can Kantrex influence milk supply or can Kantrex decrease milk supply in lactating mothers?

Aminoglycosides are poorly absorbed by the intestine. Large doses may affect intestinal flora. Be aware of the possibility of false negative results of bacterial cultures when the mother is on antibiotics. American Academy of Pediatrics: Maternal Medication Usually Compatible With Breastfeeding.

If Kantrex is required by the mother, it is not a reason to discontinue breastfeeding. Kantrex is poorly excreted into breastmilk. Newborn infants apparently absorb small amounts of other aminoglycosides, but serum levels with typical three times daily dosages are far below those attained when treating newborn infections and systemic effects of Kantrex are unlikely. Older infants would be expected to absorb even less Kantrex. Because there is little variability in the milk Kantrex 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.

Kantrex was used as part of a six-drug regimen to treat a pregnant woman with multidrug-resistant tuberculosis during the first trimester of pregnancy and postpartum. The infant was breastfed (extent and duration not stated). At age 1.8 years, the child had failure to thrive, possibly due to tuberculosis contracted after birth, but was otherwise developing normally.[4]
