The usual sodium iodide I 131 dose ranges from 4-10 mCi to treat hyperthyroidism. Doses to treat thyroid cancer are individualized and are usually 10-27 times greater than for hyperthyroidism.

Which drugs or supplements interact with sodium iodide I 131?

Non-radioactive iodine, thyroid hormone, propylthiouracil (PTU) or methimazole (Tapazole, Northyx) may all interfere with the trapping of sodium iodide I 131 by the thyroid gland. Thyroid hormone, drugs that contain iodine (for example, amiodarone [Coradone]), and iodine containing contrast agents all interfere with the action of sodium iodide I 131.
