Information in this record refers to the use of 131Iodine-Anti-B1 as a therapeutic agent. No information is available on the use of 131Iodine-Anti-B1 during breastfeeding. Because of the potential for serious adverse reactions in nursing infants, the manufacturer and expert opinion recommend not administering the drug in women who wish to continue breastfeeding.[1] If the drug is given, breastfeeding should be discontinued. Parents should limit close contact with their infants and small children after therapeutic 131Iodine-Anti-B1 administration. Suggested contact times by one group are 30 minutes per day or less of contact at a distance of 2 meters or less for a period of 6 to 23 days.[2] Another group suggests avoiding contact with small children at a distance of 10 cm for an average of 8.1 days (range 3.5 to 12.9 days).[3] Additionally, nursing mothers may have excessive I 131 uptake by the breasts, so they should receive potassium iodide or Lugol's solution before receiving 131Iodine-Anti-B1 to block uptake by the breasts and thyroid. Nursing mothers should not work with substances containing I 131 in their workplace.[4]
