Is Strontium Chloride Sr 89 safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Strontium Chloride Sr 89. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
Information in this record refers to the use of strontium 89 as a therapeutic agent. No information is available on the therapeutic use of strontium 89 during breastfeeding. It has been estimated that about 9% of the strontium in the maternal bloodstream reaches breastmilk for another strontium isotope, strontium 90.[1] Because strontium can substitute for calcium in infant bones, the manufacturer and expert opinion recommend discontinuing breastfeeding before a nursing mother receives strontium 89 chloride.[2]
