Rhenium-186 HEDP use while Breastfeeding

Summary of Use during Lactation

Information in this record refers to the use of rhenium-186 HEDP (rhenium-186 etidronate) as a therapeutic agent. No information is available on the therapeutic use of rhenium HEDP during breastfeeding. Because strontium can substitute for calcium in infant bones, the manufacturer and expert opinion recommend discontinuing breastfeeding before a nursing mother receives rhenium HEDP.[1]
