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.
“No published information” means the studies do not exist yet — not that Pentoxifylline is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
