Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

Excretion into breast milk is clinically non-significant with no side-effects observed among breastfed infants from treated mothers except rare cases of diarrhea.

Do not use while the infant is younger of two weeks of age or suffers of G-6-P dehydrogenase deficiency to avoid likelihood of hemolysis.

Be aware of false negative results that may be obtained from febrile infants with bacterial cultures when the mother is on antibiotics. Also, the possibility of developing diarrhea due to bacterial flora imbalance.
