Radio active: Wrong question. You need to work hard to avoid that happening. If possible don't share a bathroom or toilet for a week after getting the radioactive iodine. If not feasible one of you must wait an hour or longer before sharing toilet facilities.

The radioactive iodine will be in the patient's urine and sweat. With appropriate bathroom hygiene, you should not have to worry about the urine. Avoid sharing the same bed for 5-7 days, then change sheets, good hygiene. RAI does not cause "symptoms" unless you get a big dose to cause hypothyroidism. A low dose has a theoretical risk of thyroid cancer, but not with above reasonable precautions.

question on graves disease and being treated for it with radioactive iodine/ success?

2 doctor answers3 doctors weighed in

Usually successful: Success rates with i131 depend on the dose chosen, so you need to talk to your doctor on this. There are 2 schools of thought on dosing. Some doctors attempt to calculate the best dose based on thyroid size and the 24h uptake test. Others give a higher dose which works 90-95% of the time, but needs synthroid (thyroxine) supplementation sooner. Talk to your doctor about what they think is best for you.

Is radioactive iodine safe if I have multiple health issues?

Generally yes: If you're referring to radioactive iodine for treatment of hyperthyroidism, it's probably the safest treatment. Not associated with birth defects, cancer, leukemia etc. Much safer than not treating the hyperthyroidism, particularly if you have "health issues". There are also oral anti-thyroid pills. Surgery has potential risks and should be avoided except in special cases.

What to if I am having radioactive iodine 131 treatment in two weeks, does anyone have any tips for me?

Follow instruction: Just follow the instructions from your doctor, and from the nuclear medicine docs. You may have been given written instructions. Read them. Avoid dietary iodine. Follow instructions on medications, esp thyroid-related drugs (methimazole, levothyroxine, etc). If this is for graves disease, you may want to take/resume a b-blocker after the treatment since T4 and T3 (liothyronine) may increase transiently.

Radioactive iodine: Eat low i foods and avoid high i products (kelp, certain vitamins, certain cold/cough remedies). Is this for hyperthryroidism or cancer? If for hyperthyroidism, you need to wait 3-4 days, and then you can resume your (other) treatments, eg methimazole. But discuss this with your doctor. It may take 3-4 months for the rai to ablate the thyroid. Watch for symptoms of hypo.
