The problem is high dose radio-iodine. If this is a standard thyrogen protocol with a 4 mCi dose of I-131 then there is little restriction. If it is a high dose of I-131, then you would need restriction and should discuss this with the physician giving the I-131. If high dose, I usually tell patients 5-7 days away from small children.
I just took Thyrogen 2 wks ago. I did not have any special restrictions. I have a 5 year old boy and I shared food and slept with him. If you have high dose of radiation, that is a problem, you have to stay away for 3 days at least.
