Is Y90 Zevalin Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Y90 Zevalin? Is Y90 Zevalin safe for nursing mother and child? Does Y90 Zevalin extracts into breast milk? Does Y90 Zevalin has any long term or short term side effects on infants? Can Y90 Zevalin influence milk supply or can Y90 Zevalin decrease milk supply in lactating mothers?

Information in this record refers to the use of Y90 Zevalin as a therapeutic agent. No information is available on the use of Y90 Zevalin during breastfeeding. Because of the long half-life of yttrium 90, the manufacturer and expert opinion recommend not administering the drug in women who wish to continue breastfeeding.[1] If the drug is administered to a nursing mother, breastfeeding should be discontinued. No restrictions on holding the infant after administration of the drug are necessary.[2]
