Is Sodium Iodide I 123 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Sodium Iodide I 123? Is Sodium Iodide I 123 safe for nursing mother and child? Does Sodium Iodide I 123 extracts into breast milk? Does Sodium Iodide I 123 has any long term or short term side effects on infants? Can Sodium Iodide I 123 influence milk supply or can Sodium Iodide I 123 decrease milk supply in lactating mothers?

Information in this record refers to the use of sodium iodide I 123 as a diagnostic agent. Considerable controversy exists in the literature concerning the breastfeeding interruption time after the diagnostic use of sodium iodide I 123, partly depending on assumptions used for the levels of impurities, especially I 125, in commercial products. The International Commission on Radiological Protection states that breastfeeding should be interrupted for more than 3 weeks following diagnostic use of sodium iodide I 123. This usually will result in permanent discontinuation of breastfeeding for this infant.[1] However, other experts recommend much shorter times. Recent information indicates that I 125 contamination is currently much less than earlier estimates.[2] The American Thyroid Association recommends discontinuation of breastfeeding for only 3 to 4 days after a diagnostic scan.[3] The safest course of action may be to have breastmilk tested at a nuclear medicine facility at a hospital. When the radioactivity is at a safe level the mother may resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[4] Mothers who receive a dose less than 400 MBq for a thyroid scan need not refrain from close contact with their infants.[5]
