How is iobenguane I-123 given (AdreView)?

Iobenguane I-123 is injected into a vein through an IV. You will receive this injection in a clinic or hospital setting. It is usually given about 24 hours before your radiologic test.

At least 1 hour before you are treated with iobenguane I-123, you will be given a liquid drink that contains medicine to protect your thyroid from harmful radioactive effects of iobenguane I-123.

Drink extra fluids before you receive iobenguane I-123, and for at least 48 hours afterward. Follow your doctor's instructions about the types and amount of liquids you should drink before and after your test. Iobenguane I-123 is radioactive and it can cause dangerous effects on your bladder if it is not properly eliminated from your body through urination.

Expect to urinate often during the first 48 hours after your test. You will know you are getting enough extra fluid if you are urinating more than usual during this time. Urinating often will help rid your body of the radioactive iodine.
