Albumin, Iodinated I 125 Serum Levels and Effects while Breastfeeding
Summary of Use during Lactation
Information in this record refers to the use of albumin, iodinated I 125 serum (I 125 HSA) as a diagnostic agent. The International Commission on Radiological Protection states that breastfeeding should be interrupted for more than 3 weeks following diagnostic use of I 125 HSA. This usually will result in permanent discontinuation of breastfeeding for the current infant.[1]
Mothers concerned about the level of radioactivity in their milk could ask to have it tested at a nuclear medicine facility at their hospital. When the radioactivity is at a safe level, she may resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[2]
Drug Levels
I 125 is a low-energy pure gamma emitter with a physical half-life of 59.4 days.[1] Iodide is actively secreted into breastmilk and actively taken up by the mother's and infant's thyroid glands.
