Lepirudin

Summary of Use during Lactation:


Limited information indicates that lepirudin in doses up to 100 mg daily produce very low levels in milk. Because of its large molecular weight, it would not be expected to be absorbed from breastmilk by the infant. Lepirudin 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.

One mother who was 10 weeks postpartum received lepirudin 50 mg twice daily subcutaneously. Her breastmilk had undetectable (<0.1 mg/L) lepirudin levels3hours after a dose.
