here's my experience. i have/had grave's disease, went through years of unsuccessful treatment with medication (ptu and tapazole) and this past december finally had the RAI therapy.
best. decision. ever.
seriously. i put it off for years, partly because i was in college and was worried about it affecting my studies and also i was also freaked out by the procedure itself. i wish i had done it sooner.
you will receive a MUCH lower dose than anyone with thyroid cancer. i was given 12mci. i had it done on a friday afternoon, spent the weekend in our basement (it's finished!), and was free to return to most of my normal activities on monday. before the pill i had to go off my thyroid meds for a week (and the week after) and avoid high iodine foods for 3 days prior (i think my only restrictions were no cabbage, spinach, and seaweed?) the excess radiation not absorbed by the thyroid is eliminated through body fluids. i was told to drink lots and lots of water, use one bathroom, and flush twice. i did this for a few days then cleaned the bathroom thoroughly. i ate on regular plates and silverware, just no sharing for a week. i avoided contact with anyone for the weekend and then limited prolonged closeness with anyone for a week. i live at home with my parents and teenage siblings so honestly the hardest part was keeping the dog away. i'm a nanny so i was out of work for 3 weeks (would have only been 2 if one of the kids wasn't a baby). i was told not to get pregnant for anywhere from 6 months-2 years (diff. doctors).
i had no immediate side effects. however, i spent most of the winter sick (i caught everything the kids bought home from school) and had a sore throat that would NOT get better. the doctor thinks the RAI may have done some temporary damage to my throat/vocal cords and made me particularly susceptible to sore throats/losing my voice. i've been fine since. as i expected, the worst part of the whole procedure has been regulating my synthroid levels. i went back on antithyroid meds a week after the RAI, went off of them for good a month or two later, then on synthroid 3.5 months later. it took a few months to get my thyroid levels back to normal (mine swing from one extreme to another
very quickly so i was significantly hypothyroid before i started the synthroid.
i finally feel like myself again. it's like i've been living in a haze the past 6 years. my liver function was really starting to suffer from the anti-thyroid meds so my choices were RAI or thyroidectomy. as much as the idea of RAI freaked me out i would not for a minute have chosen surgery over it.
OP, you will be fine. it sounds like you have a really great situation with your sister living right down the street. i think staying at her place for at least a few days would be a great idea and then after to just limit your proximity to your kids and use a separate bathroom. best of luck to you. if you have ANY questions feel free to PM me
