FAQ – Radioiodine Treatment for Cats
Radioiodine Treatment FAQs | Common Questions Answered
Answers to common questions about radioiodine treatment for cats, including safety, hospital stay and success rates.
My cat has just been diagnosed, should I wait before radioiodine treatment?
There is no necessity to wait, or to trial medications prior to radioiodine treatment. Even with daily medication, the thyroid may continue to grow abnormally, so earlier treatment in the disease course is preferred. If your cat is on a daily antithyroid medication or a low iodine diet, this should be stopped two weeks before your appointment with us.
Is radioiodine safe?
Yes. Radioiodine treatment has no side effects. However, because of strict legislation, we are limited to the care we can give cats after they have been administered radioiodine.
Will my cat be stressed during their stay?
Most cats settle well in the ward environment. The kennels are spacious and include multiple areas for resting, eating and using the litter tray. It’s important to understand that, because of the nature of this treatment, there are strict legal limits on how much we can handle or treat cats while they are radioactive. This means that if a cat were to become unwell during their stay, our ability to examine them closely, carry out investigations, or provide certain treatments is restricted.
Although this situation is very uncommon, there is a small risk that a serious problem could arise that we are unable to fully manage while your cat is in the radioiodine unit. For this reason, we carry out thorough screening beforehand, including a detailed history and appropriate tests, to make sure your cat is suitable for treatment and to minimise any risks as much as possible.
Will my cat need treatment again?
Most cats only need one treatment. A small percentage may require a second injection if thyroid levels do not fully normalise. If your cat needs a second treatment, this is free.
Will my insurance cover treatment?
Radioiodine treatment is covered by most insurers. Please get in touch with your insurer and give them permission for the Feline Hyperthyroid Cinic to contact them to discuss your policy. We may also be able to arrange a direct payment so the treatment fee is paid directly by the insurer.
Is radioiodine the best treatment for hyperthyroidism?
For many cats, yes. Unlike medication, radioiodine treats the underlying problem rather than just controlling it, meaning no lifelong medications are required. Although there is a higher initial cost, radioiodine treatment can often work out comparable in the long run as there is no requirement for ongoing medication, tests and vet visits. The only cats we may not consider treating are those that will not allow handling, or those with other uncontrolled diseases, such as diabetes.
How do I arrange treatment?
You can speak to your usual vet about referral to the Feline Hyperthyroid Clinic, or contact us directly to discuss your cat and the next steps.
