Is R 218 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use R 218? Is R 218 safe for nursing mother and child? Does R 218 extracts into breast milk? Does R 218 has any long term or short term side effects on infants? Can R 218 influence milk supply or can R 218 decrease milk supply in lactating mothers?

No information is available on the clinical use of R 218 during breastfeeding. Because of the extremely short elimination half-life of R 218 (<2 minutes) from the body, use of R 218 either as albumin microspheres or lipid microspheres is acceptable in nursing mothers.[1] Because of the lack of information, the American College of Radiology states that temporary (~24 hours) pumping and discarding of milk may be considered.[2] However, this recommendation appears to be excessively cautious.
