Ceftriaxone Levels and Effects while Breastfeeding
Summary of Use during Lactation
Ceftriaxone is acceptable to use during breastfeeding. Limited information indicates that maternal doses of ceftriaxone of 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 cephalosporins, but these effects have not been adequately evaluated.
Drug Levels
Maternal Levels. Following administration of a 1 gram dose of ceftriaxone intramuscularly or intravenously on day 3 postpartum to 20 women, peak milk levels averaged about 0.7 and 0.5 mg/L, respectively.[1] Peaks occurred about 4 hours after the dose and fell very slowly over 24 hours with half-lives of 13 to 17 hours. The amounts in milk represent an infant dosage of about 0.5% of the maternal weight-adjusted dosage. The infant would be expected to ingest only a few milligrams of ceftriaxone per day with usual doses.
