Maternal Levels. A single dose of cefaclor 250 mg was given orally to 2 nursing mothers. In one mother it was undetectable in milk. In the other, levels of 0.15 to 0.19 mg/L occurred 2 to 4 hours after the dose; by 5 hours it was undetectable. In 5 mothers who received a single 500 mg oral dose, an average peak level of 0.21 mg/L occurred 4 hours after the dose. In individual patients, peak levels of 0.18 to 0.35 mg/L occurred 2 to 5 hours after the dose.[ 1 ] Infant Levels. Relevant published information was not found as of the revision date.
