Pentoxifylline Levels and Effects while Breastfeeding

Summary of Use during Lactation

Limited data indicate that pentoxifylline is poorly excreted into breastmilk. It would not be expected to cause any adverse effects in breastfed infants, especially if the infant is older than 2 months.

Drug Levels

Maternal Levels. Five women who had been breastfeeding for at least 6 weeks received a single 400 mg oral dose of a sustained-release form of pentoxifylline. The average total milk concentration of pentoxifylline plus its 3 active metabolites was 419 mcg/L at 2 hours after the dose and 982 mcg/L at 4 hours.[1] Using the peak milk level data from this study, an exclusively breastfed infant would receive an estimated maximum of 147 mcg/kg daily with this maternal dosage regimen or about 2% of the maternal weight-adjusted dosage. Infant Levels. Relevant published information was not found as of the revision date.
