Ceftizoxime Levels and Effects while Breastfeeding

Summary of Use during Lactation

Ceftizoxime is acceptable to use during breastfeeding. Limited information indicates that single maternal doses of ceftizoxime 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 cephalosporins, but these effects have not been adequately evaluated.

Drug Levels

Maternal Levels. After a single 1 gram intravenous dose of ceftizoxime in 2 women, milk levels ranged from 0.31 to 0.43 mg/L from 2 to 8 hours after the dose. The peak milk level occurred at 2 hours after the dose in one and 6 hours after the dose in the other.[1]

Five women were given 1 gram of ceftizoxime intravenously. Average peak milk levels of 0.39 mg/L occurred 3 hours after the dose, although individuals had peak levels ranging from 0.31 mg/L at 3 hours after the dose to 0.83 mg/L at 6 hours after the dose. Four of the women had undetectable milk levels by 6 hours after the dose.[2]

In six women given 1 gram of ceftizoxime intravenously, average milk levels were 0.25 mg/L 1 hour after the dose.[3]

After a single 1 gram intravenous dose in 2 women, ceftizoxime milk levels were measurable only 4 hours after the dose and averaged 0.1 mg/L.[4]
