Answer by Dr. Ru: About M 118 usage in lactation

The high molecular weight of both standard or non-fractionated M 118, and, so-called low molecular weight M 118 makes excretion into breast milk extremely difficult. Dalteparin has been shown not to be excreted into breast milk . In addition, M 118s 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 M 118-induced Thrombocytopenia or Osteoporosis in the mother is lower with low weight M 118s. Eleventh WHO Model List of Essential Drugs 2002: Compatible with breastfeeding.

Answer by DrLact: About M 118 usage in lactation

Although M 118 itself has not been studied, low molecular weight M 118s (e.g., dalteparin, enoxaparin) are not excreted into breastmilk in clinically relevant amounts. Because M 118 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]
