Drug Levels and Effects

Summary of Use during Lactation

Limited information indicates that cefotaxime 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 cephalosporins, but these effects have not been adequately evaluated. Cefotaxime is acceptable in nursing mothers.

Drug Levels

Maternal Levels. Five postpartum women were given 2 grams of cefotaxime twice daily for 4 days. The average peak milk level on day 4 was 0.68 mg/L (range 0.29 to1.57 mg/L). By 12 hours after the dose the drug was undetectable in milk of all 5 women.[1]

After a single 1 gram dose of cefotaxime to 12 women, average peak levels of 0.32 mg/L occurred 2 hours after the dose. The highest milk level recorded was 0.52 mg/L in one woman at 3 hours after the dose.[2][3]

After a single 1 gram dose of cefotaxime to 5 women, the drug was not measurable (<0.1 mg/L) in the mothers' milk at any time up to 6 hours after the dose.[4]

After a single 1 gram intravenous dose in 2 women, cefotaxime milk levels were not measurable at any time up to 6 hours after the dose.[5]
