Is Marcumar Safe in Breastfeeding

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

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