Is Phenprocoumarol Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Phenprocoumarol? Is Phenprocoumarol safe for nursing mother and child? Does Phenprocoumarol extracts into breast milk? Does Phenprocoumarol has any long term or short term side effects on infants? Can Phenprocoumarol influence milk supply or can Phenprocoumarol decrease milk supply in lactating mothers?

Phenprocoumarol is not approved for sale by the U.S. Food and Drug Administration (FDA). Limited information indicates that anticoagulant maternal doses of Phenprocoumarol produce low levels in milk. Until more data are available, shorter-acting anticoagulants are preferred, especially if the infant is younger than 2 months.
