◉ 母乳喂养期间使用总结:有限的信息表明青霉素G在乳汁中产生低水平,预计不会对哺乳婴儿造成不良影响。偶尔有报道青霉素会破坏婴儿的胃肠道菌群,导致腹泻或鹅口疮,但这些影响尚未得到充分评估。青霉素G对哺乳母亲是可接受的。
◉ 对哺乳婴儿的影响:一名患有先天性梅毒的1个月大母乳喂养婴儿,在其母亲接受240万单位苄青霉素G肌肉注射后6小时出现赫克斯海默反应。然而,婴儿在大约同一时间也接受了10单位青霉素G。反应可能是由母乳中的青霉素引起的。

◉ Summary of Use during Lactation:Limited information indicates that penicillin G 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. Penicillin G is acceptable in nursing mothers.
◉ Effects in Breastfed Infants: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 penicillin G intramuscularly. However, the baby had also received 10 units of penicillin G at about the same time as the mother's injection. The reaction was possibly caused by penicillin in breastmilk.
◉ Effects on Lactation and Breastmilk:Relevant published information was not found as of the revision date.
