Your 2-Week Hypothyroid Regimen

During the first week of your regimen, you will have blood work and scans. These scans let us know where the thyroid cancer is. You will then receive your radioactive iodine treatment. You may be admitted to the hospital for treatment. If you are admitted, you will be discharged from the hospital when your level of radioactivity is low enough. If you are not admitted, you will receive other instructions.

During the second week, you will have a post-treatment scan, which a staff member in Nuclear Medicine will arrange for you.

Below is a typical regimen schedule:

Week 1
May start Monday-Thursday
Day 1
(2 to 3 hours)
  • Blood work
  • Diagnostic dose of radioactive iodine
Day 2
(30 to 60 minutes)
  • Scan
  • Treatment dose of radioactive iodine
Week 2

Other tests that you may have include:

  • A pregnancy test (blood draw) for women before treatment to make sure that they are not pregnant. This is a hospital requirement for treatment.
