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.

Limited information indicates that Benzopenicillin 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. Benzopenicillin 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 Benzopenicillin intramuscularly. However, the baby had also received 10 units of Benzopenicillin at about the same time as the mother's injection. The reaction was possibly caused by penicillin in breastmilk.[5]
