Is Ro 1-4849 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Ro 1-4849? Is Ro 1-4849 safe for nursing mother and child? Does Ro 1-4849 extracts into breast milk? Does Ro 1-4849 has any long term or short term side effects on infants? Can Ro 1-4849 influence milk supply or can Ro 1-4849 decrease milk supply in lactating mothers?

Ro 1-4849 is not approved for sale by the U.S. Food and Drug Administration (FDA). Limited information indicates that anticoagulant maternal doses of Ro 1-4849 produce low levels in milk. Until more data are available, shorter-acting anticoagulants are preferred, especially if the infant is younger than 2 months.
