Is Rubidium Chloride Rb 82 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 Rubidium Chloride Rb 82. 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 rubidium chloride Rb 82 as a diagnostic agent. No information is available on the use of rubidium chloride Rb 82 during breastfeeding. The manufacturer recommends withholding breastfeeding for 1 hour after a diagnostic dose of rubidium chloride Rb 82.This length of time is greater than 10 half-lives of the radioisotope, so the nursing infant should not be exposed to radiation if this guideline is followed. The mother can nurse just before administration of the radiopharmaceutical. If the mother has expressed and saved milk prior to the examination, she can feed it to the infant during the period of nursing interruption.[1,2] Other authorities state that no discontinuation of breastfeeding is necessary.[3]
