Is Perflutren Protein-Type A Microspheres injection Safe in Breastfeeding

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

No information is available on the clinical use of Perflutren Protein-Type A Microspheres injection during breastfeeding. Because of the extremely short elimination half-life of Perflutren Protein-Type A Microspheres injection (<2 minutes) from the body, use of Perflutren Protein-Type A Microspheres injection 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.
