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.
