What is the function of the thyroid?
The thyroid is equipped with an active system or “pump” for moving iodine into its cells, where it is concentrated as iodide. The thyroid gland is the only tissue in the body that takes up and holds onto iodine.
Do you need to have your thyroid destroyed to treat hyperthyroidism?
While there may be instances when you won't need to have the entire thyroid gland rendered nonfunctional to alleviate your hyperthyroid symptoms, total destruction of the thyroid is most often necessary. Your doctor may refer to it as radioactive iodine ablation (ablation is a term that refers to destruction or erosion).
What is used to destroy thyroid tissue?
Because of this, radioactive iodine (RAI, also called I-131) can be used to treat thyroid cancer. The RAI collects mainly in thyroid cells, where the radiation can destroy the thyroid gland and any other thyroid cells (including cancer cells) that take up iodine, with little effect on the rest of your body.
What medication destroys the thyroid gland?
Radioiodine therapy is a common and effective treatment for hyperthyroidism. It involves taking radioactive iodine by mouth as a capsule or liquid. This slowly destroys the cells of the thyroid gland that produce thyroid hormone. It does not affect other body tissues.
What is radioiodine ablation?
Radioiodine remnant ablation (RRA) is the destruction of this remnant thyroid tissue with the administration of radioactive iodine (RAI). RRA is considered as a safe and effective method for eliminating residual thyroid tissue, as well as microscopic disease if at all present in thyroid bed.

Surgery for hyperthyroidism was associated with a lower risk of all-cause and cardiovascular death as compared to radioactive iodine therapy during long-term follow-up, particularly in men.
What is the best treatment for thyroid?
The most common treatment is levothyroxine (Levoxyl, Synthroid, Tirosint, Unithroid, Unithroid Direct), a man-made version of the thyroid hormone thyroxine (T4). It acts just like the hormone your thyroid gland normally makes. The right dose can make you feel a lot better.
How is radioactive iodine administered?
Radioactive iodine is usually given in pill form, but it can also be given in liquid form if needed. Some people have trouble swallowing pills. If you do, tell your doctor in Molecular Imaging and Therapy Service (MITS) before your treatment. This is sometimes called the Nuclear Medicine service.

How long does radioiodine stay in your system?
The radioiodine from your treatment will temporarily remain in your body. Most of the radioiodine not taken up by your thyroid gland will be eliminated within the first (2) two days after treatment. Radioiodine leaves your body primarily by your urine. Very small amounts may leave in your saliva, sweat, or feces.
Which patient would be a candidate for radioactive iodine therapy?
Patients who have papillary or follicular thyroid cancer that has spread to the lymph nodes, neck or other areas of the body are the best candidates for radioiodine therapy. Patients who have localized thyroid cancer that has not spread may be better candidates for surgery.
Is radioiodine therapy safe?
Radioactive iodine (RAI) is treatment for overactive thyroid (hyperthyroidism) and certain types of thyroid cancer. The term “radioactive” may sound frightening, but it is a safe, generally well-tolerated, and reliable treatment that targets thyroid cells so there is little exposure to the rest of your body's cells.

What is the I-131 thyroid?
THYROID TISSUE – I-131 is given to destroy overactive thyroid tissue (see Hyperthyroidism brochure) or to shrink thyroid glands that are functioning normally but are causing problems because of their size (see Goiter brochure ). Patients are asked to follow some radiation precautions after treatment in order to limit radiation exposure to others (see chart). I-131 may occasionally cause mild pain in the neck that can be treated with aspirin, ibuprofen or acetaminophen. The RAI treatment may take up to several months to have its effect. Frequently, the end result of RAI treatment of hyperthyroidism is hypothyroidism, which is treated by thyroid hormone replacement (see Hypothyroidism brochure ).
What is the I-123 isotope used for?
I-123 is the usual isotope used to take pictures and determine the activity of the intact thyroid gland ( Thyroid Scan and Radioactive Iodine Uptake, RAIU ), since it is harmless to thyroid cells.

How does I-131 work?
This is performed after the remaining thyroid cells ( including any cancer cells) are stimulated by raising TSH levels by either withdrawing the thyroid hormone pills or by treating with recombinant human TSH. Patients are asked to follow some radiation precautions after treatment in order to limit radiation exposure to others ( see below ). Depending on state regulations, patients may have to stay isolated in the hospital for about 24 hours to avoid exposing other people to radiation, especially if there are young children living in the same home.
What is iodine used for?
Iodine, in the form of iodide, is made into two radioactive forms of iodine that are commonly used in patients with thyroid diseases: I-123 ( harmless to thyroid cells) and I-131 ( destroys thyroid cells ).

Is rai safe for thyroid?
In general, RAI is a safe and effective treatment for the thyroid disorders mentioned above. Hypothyroidism is a common side effect of RAI for hyperthyroidism and always seen after RAI for thyroid cancer. This is usually easily treated with thyroid hormone replacement (see Hypothyroidism brochure ). Some studies suggest a slight increase in thyroid cancers may be seen after RAI treatment for hyperthyroidism. Loss of taste and dry mouth due to salivary gland damage may be seen. The use of lemon drops, vitamin C or sour stimulation to potentially decrease the exposure of the salivary glands to RAI is controversial and should be discussed with your physician. Importantly, once you have been treated with RAI, regular medical follow-up is lifelong.

What is the purpose of iodine 131?
I-131 is the destructive form used to destroy thyroid tissue in the treatment of thyroid cancer and with an overactive thyroid. I-123 is the non-destructive form that does not damage the thyroid and is used in scans to take pictures of the thyroid (Thyroid Scan) or to take pictures of the whole body to look for thyroid cancer (Whole Body Scan).
Why do we need radioactive iodine?
Radioactive iodine initially is given to destroy any residual thyroid cancer cells left behind after surgery. Once routine in all thyroid cancer patients, newer guidelines by the American Thyroid Association have recommended more limited use of radioactive iodine therapy.
Does radioactive iodine therapy affect thyroid cancer?
This study suggests that the timing of radioactive iodine therapy relative to thyroidectomy did not alter disease outcomes in thyroid cancer. This finding allows for more flexibility in timing when scheduling radioactive iodine therapy following thyroidectomy and, thus, patients can have more input on this timing relative to their life schedule.
