Radioactive Iodine (I131) - A Cure for Feline Hyperthyroidism

Radioactive Iodine is the safest, best and ultimately least costly lifetime treatment for most hyperthyroid cats.

I131 is a great alternative to lifelong daily medications that must be given to cats. These medications also have serious side effects in up to 10% of cats. The cost of these medications and follow ups can cost $550-$700 per year.
I131 is very effective in treating hyperthyroidism. The first dose will treat 97-98% of cats. 70% of cats will have normal thyroid levels within one week of therapy. 90% will have normal thyroid levels by one month and 97% have normal levels by three months. Following successful therapy, only 0.3% cats will become hyperthyroid again in their lifetime.

The I131 is administered as a single injection under the skin just like a vaccine is given. Treated cats are kept in the hospital for 4-5 days to allow most of the radioactive iodine to be excreted per Radiation Protection Statutes.
