Ertapenem Levels and Effects while Breastfeeding
Summary of Use during Lactation
Limited information indicates that single maternal doses of ertapenem up to 1 gram produce 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 has been reported with beta-lactams, but these effects have not been adequately evaluated.
Drug Levels
Maternal Levels. Five women who were 5 to 14 days postpartum received ertapenem 1 gram daily for 3 to 10 days for acute pelvic infections. Breastmilk samples were obtained before the first dose and twice during the 24 hours after the last dose as well as daily in the morning for 2 to 5 days after the last dose. Milk concentrations during the first 24 hours of the last dose ranged from <0.125 mg/L to 0.3 mg/L. Milk concentration was <0.125 mg/L by day 3 in 4 of the women and after 5 days in the 5th.[1]
