How to treat RAI?
For RAI therapy to be most effective, you must have a high level of thyroid-stimulating hormone (TSH or thyrotropin) in the blood. This hormone is what makes thyroid tissue (and cancer cells) take up radioactive iodine. If your thyroid has been removed, there are a couple of ways to raise TSH levels before being treated with RAI: 1 One way is to stop taking thyroid hormone pills for several weeks. This causes very low thyroid hormone levels (hypothyroidism), which makes the pituitary gland to release more TSH. This intentional hypothyroidism is temporary, but it often causes symptoms like tiredness, depression, weight gain, constipation, muscle aches, and reduced concentration. 2 Another way is to get an injection (shot) of thyrotropin (Thyrogen), which can make withholding thyroid hormone for a long period of time unnecessary.

Mechanism of action
Contraindications
- The American Thyroid Association recommends that all pregnant and breastfeeding women in the United States and Canada take a prenatal vitamin containing 150 mcg of iodine a day as part of an overall recommended intake of 220 mcg/day and 290 mg/day, respectively. Excess iodine, however, can be particularly dangerous in these women.
Effects
- The impact of too little iodine reaches further. Children born to mothers with severe iodine deficiency can suffer from stunted growth, severe and irreversible intellectual disabilities, and problems with movement, speech, and hearing.
Prognosis
- Even mild iodine deficiency during pregnancy can lead to subtle intellectual deficits, although many children improve with iodine supplementation.
Clinical significance
- Fibrocystic breast disease, a benign condition characterized by lumpy, painful breasts mostly in women of reproductive age, is also associated with iodine deficiency.
Epidemiology
- The World Health Organization (WHO) estimates that two billion people, including 285 million school children, are iodine deficient. Among them, iodine deficiency disorders (IDD) affect some 740 million. In the United States, however, the risk of iodine deficiency is relatively low; incidence of IDD has dropped significantly since the iodization of salt first began in the 1920s. To further s…
Risks
- That said, there are certain risk factors for iodine deficiency that everyone should be aware of no matter where they live:
Treatment
- Some practitioners are almost knee-jerk in their insistence that anyone with a thyroid problem requires iodine supplementation; alternative practitioners may recommend iodine-containing herbs, like kelp or seaweed.
Interactions
- This can be particularly risky, in part because iodine supplements can interact with several types of drugs, including anti-thyroid drugs used to treat hyperthyroidism. Taking high doses of iodine with anti-thyroid medications can have an additive effect and could cause hypothyroidism.
Adverse effects
- In addition, large amounts of iodine block the thyroid's ability to make thyroid hormones. The conclusion of two studies, one published in 2006 in the New England Journal of Medicine (NEJM), the other in 2014 in the journal Endocrinology and Metabolism, is that more-than-adequate or excessive iodine levels are unsafe and may lead to hypothyroidism and autoimmune thyroiditis (…
Diagnosis
- While iodine can be detected in urine, relying on such a test is not helpful, since 90 percent of the iodine you ingest is quickly expelled. Rather, doctors use thyroid tests to determine if your iodine intake is concerning or not. In addition, iodine deficiency is typically suspected based on the development of goiter, hypothyroidism, or congenital hypothyroidism (low thyroid function at birt…
