Answer by Dr. Ru: About Heparinum usage in lactation

The high molecular weight of both standard or non-fractionated Heparinum, and, so-called low molecular weight Heparinum makes excretion into breast milk extremely difficult. Dalteparin has been shown not to be excreted into breast milk . In addition, Heparinums are inactivated in the GE tract where they are not absorbed which is reason to have a nil oral bioavailability. Absence of anti-clotting activity in breastfed infants has been shown after treatment of the mother with Enoxaparin. Risk of Heparinum-induced Thrombocytopenia or Osteoporosis in the mother is lower with low weight Heparinums. Eleventh WHO Model List of Essential Drugs 2002: Compatible with breastfeeding.

Answer by DrLact: About Heparinum usage in lactation

Although Heparinum itself has not been studied, low molecular weight Heparinums (e.g., dalteparin, enoxaparin) are not excreted into breastmilk in clinically relevant amounts. Because Heparinum has an even higher molecular weight of 3000 to 30,000 daltons, it would not be expected to be appreciably excreted into breastmilk or absorbed by the infant. No special precautions are required.[1]
