Is Sodium Chromate Cr 51 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 Sodium Chromate Cr 51. 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 sodium chromate Cr 51 as a diagnostic agent. No information is available on the use of sodium chromate Cr 51 during breastfeeding. The manufacturer recommends withholding breastfeeding after a diagnostic dose of sodium chromate Cr 51, but does not provide a specific duration. The long biological and physical half-lives of chromium may preclude resumption of breastfeeding of the infant. Mothers concerned about the level of radioactivity in their milk could ask to have it tested at a nuclear medicine facility at their hospital and when the radioactivity is at background levels they may safely resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[1]

Chromium 51 is a gamma emitter with a principal photon energy of 320 keV and a physical half-life of 27.7 days.[2] Chromate binds to red blood cells and is eliminated with a biologic half-life of 25 to 35 days.
