Is Tauroselcholic Acid Se-75 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 Tauroselcholic Acid Se-75. 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 tauroselcholic acid Se-75 (SeHCAT; selenium-75 homocholic acid taurine) as a diagnostic agent. Information from one patient indicates that the effective radiation dose to the infant from SeHCAT excreted in breastmilk over 6 months is below any established dose limits and no special precautions are required.[1]
Effects on the breastfed infant

Effects on milk supply

Levels in milk
Selenium Se 75 decays by electron capture with a physical half-life of approximately 119 days.
Maternal Levels. A nursing mother who was 3 months postpartum was given a capsule containing 370 kBq of SeHCAT as a diagnostic test. She collected 3 milk samples daily for 7 days. The effective radiation dose to the infant was 7 microSv over the 7-day period and the radiation dose over a 6-month period of exclusive breastfeeding was estimated to be 17 microSv.[1]
Infant Levels. Relevant published information was not found as of the revision date.
“No published information” means the studies do not exist yet — not that Tauroselcholic Acid Se-75 is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
