Drug Levels and Effects:

Summary of Use during Lactation:

Cefuroxime is acceptable to use during breastfeeding. Limited information indicates that maternal doses of cefuroxime up to 2.25 grams daily byinjectionproduce low levels in milk that are not expected to cause severe 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.

A single intravenous dose of 750 mg of cefuroxime was given to 5 women. The average peak cefuroxime level in milk was 0.37 mg/L 3 hours after the dose. Individual peak levels of 0.33 to 0.5 mg/L occurred 2 to 4 hours after the dose.[1]

A single intramuscularinjectionof 750 mg of cefuroxime was given to 8 women with endometritis. Milk cefuroxime levels increased from 0.34 mg/L at 30 minutes after theinjectionto 1.45 mg/L at 8 hours after theinjection.[2]

After cefuroxime 750 mg three times daily intramuscularly, peak milk levels averaging 1.2 mg/L occurred 6 hours after the dose. Cefuroxime was detectable at a concentration of 0.36 mg/L 30 minutes after the dose, and by 8 hours the milk level had decreased to 1.06 mg/L.[3]

No studies have measured cefuroxime in milk after oral administration, but milk levels would be expected to be much lower than the values above.
