I was prescribed Cyclokapron (Tranexamic Acid) to treat heavy menstrual bleeding. I am breastfeeding my 21 month-old twins. The specialist didn't ask if I was still nursing before prescribing the drug and my Internet research suggests that it s not appropriate for nursing mothers. Your input is appreciated.

We know practically nothing about this product, but the levels in breastmilk seem low, about 1% of the moms dose. This would probably not affect the breastfed infant.

Tranexamic acid is used to reduce or prevent hemorrhage (excessive bleeding) in hemophilia and in other bleeding disorders. This is accomplished by inhibiting the conversion of plasminogen to plasmin.[1] From unpublished data from the manufacturer, tranexamic acid is excreted into human milk and is present in the mother's milk at a concentration of about one-hundredth of the corresponding serum concentrations.[1] In one unpublished study, it was determined that after a 2 day treatment of tranexamic acid in lactating women, the milk concentration was approximately 1% of the peak serum concentration. The effects on an infant receiving a small amount of tranexamic acid is not known.
