(Cancer dosages are typically stronger.) The therapy’s complete effects are sometimes not seen until six months have passed. A decade ago, we gave radioactive iodine therapy to everybody — even someone with the smallest papillary carcinoma. But review of the data shows that not all patients need it. We may not need to treat all thyroid cancers, as most grow slowly and patients have excellent outcomes with surgery alone. When we’re using radioactive iodine therapy to treat thyroid cancer or hyperthyroidism, higher doses are required. The iodine molecules emit radiation, which destroys the malfunctioning thyroid cells.
People may take RAI orally, in the form of capsules or a drink, or through intravenous injections.

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.
We will also make sure that they are comfortable and willing to eat in the hospital. People must avoid any activities at work or home that put them in close contact with young children or pregnant people. They will need to avoid these activities for several days. People will usually be able to return home after having RAI treatment. They must avoid close contact with people for several days following treatment.

Radioiodine stays in your body for only a short time. Most of the radioiodine that does not go to thyroid tissue will be eliminated from your body during the first few days after treatment. Radioiodine leaves your body primarily through your urine, but very small amounts can be found in your saliva, sweat and bowel movements.
Don’t eat for 1 to 2 hours after you take this medication, or as instructed by your doctor. From diagnosis to treatment, our experts provide the care and support you need, when you need it.

Radioactive Iodine (Radioiodine) Therapy for Thyroid Cancer
You'll be checked regularly for the amount of radiation in your body. You can go home as soon as it falls to a safe level for the people around you, usually after about 4 to 7 days. In the meantime you stay in a single room at the hospital. Radioactive iodine therapy is a type of internal radiotherapy treatment for thyroid cancer. It can also help to diagnose and treat some other cancers and conditions.
Keep your dishes away from other dishes and utensils. Also, wash these items separately from other household dishes so you don't spread radioactive particles to other items. You can use the dishwasher, as long as you're washing separate loads for your dishes. Your doctor will give you more written instructions. The instructions will tell you how far to stay away from people and how long you need to follow precautions. They will list other ways to keep other people safe.
In the days immediately following your RAI therapy, be aware of these general precautions to prevent radioactive exposure to others. Your thyroid gland absorbs nearly all of the iodine in your body. Because of this, radioactive iodine (RAI, also called I-131) can be used to treat thyroid cancer.
In the body, thyroid hormone and thyroglobulin are the only molecules that require iodine. Therefore, all ingested iodine goes only to the thyroid gland through the Na+/I- symporter. If iodine is tagged with radioactivity (I-131), beta particles will destroy the local tissues in the hyperactive adenomas. Adjacent normal tissues can also be destroyed by collateral damage. Radioiodine can be administered subcutaneously, intramuscularly, or through the mouth.
If you’re getting the liquid form of radioactive iodine, you’ll need to drink about a teaspoon of liquid . You’ll drink it out of a small vial through a straw. Most people say it tastes like water, but some say that it has a slightly stale or musty taste. Another way is to get an injection of thyrotropin , which can make withholding thyroid hormone for a long period of time unnecessary.

Arrangements should be made for others to provide childcare for infants and very young children.

Similarly, when you brush your teeth, spit into the toilet bowl. On both occasions, flush the toilet twice after use. Avoid close contact, kissing, and sexual activity. You may need to sleep in a separate bed from your partner. Same ones used in nuclear medicine facilities, can be purchased for home use as well.
If you drink alcohol, drink no more than 1 or 2 drinks per day. You can shower with soap and water the night before or the morning of your treatment. Your doctor will discuss your treatment plan with you. American Cancer Society medical information is copyrighted material.
