Answer by Dr. Ru: About Heparine [INN-French] usage in lactation

The high molecular weight of both standard or non-fractionated Heparine [INN-French], and, so-called low molecular weight Heparine [INN-French] makes excretion into breast milk extremely difficult. Dalteparin has been shown not to be excreted into breast milk . In addition, Heparine [INN-French]s 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 Heparine [INN-French]-induced Thrombocytopenia or Osteoporosis in the mother is lower with low weight Heparine [INN-French]s.

Answer by DrLact: About Heparine [INN-French] usage in lactation

Although Heparine [INN-French] itself has not been studied, low molecular weight Heparine [INN-French]s (e.g., dalteparin, enoxaparin) are not excreted into breastmilk in clinically relevant amounts. Because Heparine [INN-French] 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]
