About radioactive iodine treatment
Radioiodine is a form of iodine that is radioactive and is used to treat thyroid glands that are overactive or enlarged. It is given as a capsule or drink if required. It is safe, effective and has been in use for over 75 years. Most of the radioactivity is taken up by the thyroid, where it slows down the production of thyroid hormone and causes it to get smaller. The rest of the radioiodine is passed harmlessly out of the body, mostly in the urine.
Radioiodine is a permanent, painless and effective treatment for thyroid activity which in most cases avoids the need for surgery.
