Dicloxacillin Levels and Effects while Breastfeeding
Summary of Use during Lactation
Dicloxacillin is acceptable to use during breastfeeding and is frequently used to treat mastitis in nursing mothers.[1][2] Limited information indicates that dicloxacillin levels in milk are low and 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 penicillins, but these effects have not been adequately evaluated.
Drug Levels
Maternal Levels. After a single oral dose of 250 mg of dicloxacillin in 2 women, milk levels ranged from 0.2 to 0.3 mg/L between 2 and 4 hours after the dose. The drug was undetectable in milk at 1 and 6 hours after the dose.[3]
