Cefmetazole Breastfeeding Warnings

There are no reports of adverse side effects in nursing infants whose mothers are receiving cefmetazole. Some experts warn of the possibility of unknown direct side effects in the nursing infant, modification of neonatal bowel flora, and difficulty in the interpretation of culture results in the evaluation of a suspected infection.

Cefmetazole is excreted into human milk in trace amounts. Adverse effects in the nursing infant are unlikely.
