Vancomycin Levels and Effects while Breastfeeding

Summary of Use during Lactation

Limited information indicates that vancomycin produces low levels in milk and because vancomycin is poorly absorbed orally, it is not likely to reach the bloodstream of the infant or cause any adverse effects in breastfed infants. No special precautions are required.

Drug Levels

Maternal Levels. A single colostrum level of 12.7 mg/L was found 4 hours after the end of the infusion of vancomycin 1 g intravenously given every 12 hours in one woman. Her peak and trough serum levels were 36.1 and 12.5 mg/L, respectively. The colostrum was obtained after delivery at a gestational age of about 35 to 38 weeks.[1] Assuming level reported is about the average colostral level over the dosing interval, an exclusively breastfed infant would receive 1.9 mg/kg daily by mouth in breastmilk. The amount in mature milk might be lower. This dose is only about 4.8% of the oral vancomycin dose of 40 mg/kg daily used to treat pseudomembranous colitis in infants.
