Is Sodium iotalamate (125I) Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Sodium iotalamate (125I)? Is Sodium iotalamate (125I) safe for nursing mother and child? Does Sodium iotalamate (125I) extracts into breast milk? Does Sodium iotalamate (125I) has any long term or short term side effects on infants? Can Sodium iotalamate (125I) influence milk supply or can Sodium iotalamate (125I) decrease milk supply in lactating mothers?

Information in this record refers to the use of Sodium iotalamate (125I) as a kidney function diagnostic agent. No information is available on the use of Sodium iotalamate (125I) during breastfeeding. However, the biologic half-life of iothalamate after intravenous administration is 1.5 hours with normal kidney function, so the drug will be almost completely eliminated from the body in 8 hours. This time may be longer in patients with impaired kidney function and in patients who receive the drug by subcutaneous injection.[1] 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.[2][3][4] 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 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.[5]
