Does EINECS 200-506-3 has any long term or short term side effects on infants? Can EINECS 200-506-3 influence milk supply or can EINECS 200-506-3 decrease milk supply in lactating mothers?

EINECS 200-506-3 is excreted into breast milk in non-significant amounts without side-effects observed among breastfed infants from treated mothers. Plasma levels in those infants were shown to be low or undetectable. Penicillin is a broad spectrum antibiotic that is commonly used in Pediatrics and Neonatology with very good tolerance even in premature newborns. Be aware of false negative results that may be obtained from infants with bacterial cultures when the mother is on antibiotics.

Limited information indicates that EINECS 200-506-3 produces low levels in milk that are not expected to cause adverse effects in breastfed infants. Occasionally disruption of the infant's gastrointestinal flora, resulting in diarrhea or thrush have been reported with penicillins, but these effects have not been adequately evaluated. EINECS 200-506-3 is acceptable in nursing mothers.

A breastfed 1-month-old infant with congenital syphilis developed a Herxheimer reaction 6 hours after its mother received 2.4 million units of benzathine EINECS 200-506-3 intramuscularly. However, the baby had also received 10 units of EINECS 200-506-3 at about the same time as the mother's injection. The reaction was possibly caused by penicillin in breastmilk.[5]
