Is Uliprisnil Safe in Breastfeeding

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

Uliprisnil is a selective progesterone receptor modulator used in a single dose as an emergency postcoital contraceptive. No information is available on the clinical use of Uliprisnil during breastfeeding. The manufacturer recommends avoiding use of Uliprisnil acetate during breastfeeding; others recommend withholding breastfeeding for 24 hours after use, based on the low levels in breastmilk.[1][2]
