How to treat hyperthyroidism in cats?
Feline Hyperthyroidism may be treated with medicine, surgery, or radioactive iodine: 1 Medical therapy for feline hyperthyroidism (methimazole - Tapazole®) is required daily, is a life-long treatment, and does not cure the cat's hyperthyroid condition. The difficulties associated with giving pills to cats often causes stress to both the animal and owner. Tapazole may have side effects, especially relative to the liver and blood system. The drug therapy must be adjusted, based on periodic blood tests, and the cost of therapy and tests is usually over $800 per year. 2 Surgical therapy for feline hyperthyroidism requires anesthesia, may need to be repeated, and may result in a deficiency of parathyroid hormone if these glands are inadvertently removed. Surgery may not be effective in removing all of the affected thyroid tissue causing feline hyperthyroidism. 3 Radioactive Iodine (I-131) therapy for feline hyperthyroidism is very effective, has few side effects, is a one-time treatment in over 95% of cats with hyperthyroidism, and does not require administration of pills or anesthesia. One injection under your cat's skin is all that is needed! The cost of radioactive iodine therapy is similar to the other forms of therapy, and is often less expensive when compared to long term medical therapy or the higher probability of a required second surgery.

Once his radiation levels come down and you can bring him home, you still have to keep him away from young children and pregnant women, as he'll pass small amounts of radioactive iodine through his urine for approximately two weeks. He also can't sleep with you during that time, and the facility will inform you about special arrangements you'll have to make for disposing of his litter.
