Within days, the radioactive iodine
passes out of your body in your urine. How long it takes will depend on the dose you received and your age. Young people get rid of radioactive iodine faster than older adults.
Most people don't feel different after treatment. But a few people may feel a little nauseated.
Your doctor will give you written instructions. To avoid exposing other
people to radioactivity, it is important to follow your doctor's instructions carefully. He or she will instruct you on how far to stay away from people, how long you need to sleep alone, and other ways to stay safe. You will be directed to avoid
close contact, kissing, sex, and sharing cups, dishes, or utensils.
Wash your hands well with soap and lots of water
each time you use the toilet.
Use separate towels, washcloths, and sheets. Wash
these and your personal clothing by themselves and not with other people's laundry.
You may want to use a special plastic trash bag for all your trash, such as bandages, paper or plastic dishes, menstrual pads, tissues, or paper towels. Talk to your treatment facility to see if they will handle the disposal. Or after 80 days, this bag can be thrown out with your other trash.
Don't cook for other people. If cooking is necessary, use plastic gloves and throw them away in the special plastic trash bag.
Wash your dishes in a dishwasher or by hand. If you use disposable dishes, they must be thrown away in the special plastic trash bag.
Why It Is Done
Radioactive iodine may be used to
treat hyperthyroidism in people who have noncancerous (benign) thyroid nodules
that make too much
Radioactive iodine is
also used if you have your thyroid removed (thyroidectomy) because of thyroid
cancer. Radioactive iodine therapy destroys any remaining thyroid tissue or
cancer cells that were not removed during surgery.
How Well It Works
In almost all cases, your thyroid
hormone levels will return to normal or below normal after radioactive iodine
treatment. This may take 8 to 12 weeks or longer. If your thyroid hormone level
does not go down after 6 months, you may need another dose of radioactive
If you have thyroid cancer and you are treated with
radioactive iodine, it may take from several weeks to many months for your body
to get rid of any remaining cancer cells.
Your thyroid nodule is
unlikely to grow after being treated with radioactive iodine.
The risks from radioactive iodine treatment
Metallic taste in your mouth.
Neck pain. Radioactive iodine
treatment can make your neck swell up or hurt.
If you are pregnant, you should
not receive radioactive iodine treatment. This kind of treatment can damage
your fetus's thyroid gland or expose your fetus to radioactivity.
You should not breast-feed your baby after you have been treated with
radioactive iodine. Ask your doctor when it is safe to breast-feed.
people with thyroid cancer will receive different doses of radioactive iodine.
If you are young and you do not have a great risk of your cancer coming back,
you will probably need less radioactive iodine than an older person. Sometimes
this means that a younger person who receives radioactive iodine treatment will
not have to stay overnight in a hospital.
Traveling after treatment
If you have had
radioactive iodine treatment and you want to travel 3 to 4 days after
treatment, it is important to prepare for any problems you may have at airport
security. People who have had radioactive iodine treatment can set off the
radiation detection machines in airports for a week to 10 days.
If you plan to travel by airplane within 3 or 4 days after your treatment, check with local authorities about any steps or permission you may need to travel.
If you plan to travel on the interstate, you may set off radiation detectors. Most police and transportation workers are aware of medical radiation, but it may be a good idea to carry some paperwork from your doctor.
