  • For two hours before the procedure, do not eat or drink anything. Water may be allowed.
  • If you are a woman of childbearing age, the doctor will do a pregnancy test.
  • A thyroid uptake and scan may be done before the treatment.

At least an hour

Will It Hurt?

The treatment is painless.

Postoperative Care

Any radioactive iodine that is not taken up directly by the thyroid will be passed through the urine. Be sure to follow your doctor's instructions , which may include:

  • Do not eat any solid foods for at least two hours following the treatment. Drink a lot of clear liquids (water or juice).
  • For the first 8-12 hours following treatment, use the bathroom every hour. This will help flush the excess iodine from your body.
  • Limit your contact with others. Do not enter a room with any infants or children in it. Stay at least three feet away from other adults. Do not stay near any other adult for more than a few minutes. Do not share a bed with anyone for 48 hours following the treatment.
  • Do not share any food, drink, or dishes with anyone for the first week. Do not allow your saliva to come into contact with anyone. Avoid kissing and sexual contact.
  • Flush the toilet twice after use.
  • Wash hands often and thoroughly.
  • Resume normal thyroid medicines 48 hours after the treatment.

The majority of people who undergo the treatment will have their thyroid levels return to normal within 8-12 weeks. However, in a small number of patients, a second dose of radioactive iodine treatment is needed.

A follow-up visit with your doctor will be scheduled 4-6 weeks after treatment. Radioactive active iodine treatment can cause hypothyroidism (low thyroid function). This can occur at any time after treatment. Your doctor will need to check your thyroid status every few months until levels are stable.
