Radioactive iodine therapy for feline hyperthyroidism

Options for Owners of Hyperthyroid Cats

As every cat owner knows, giving medications to our feline companions can be a frustrating and unpredictable experience. Some cats take medications regularly and without fuss, while other have personalities that make regular treatment much more challenging. So, while methimazole (Tapazoleâ„•) is a medical treatment option, it is not optimal for all families.


Surgery is also fraught with its own issues, when trying to remove only the abnormal thyroid tissue while maintaining thyroid and parathyroid function post-operatively.


Our Radioactive Iodine Treatment for cats with hyperthyroidism is designed to provide this modern treatment at a reasonable cost. A single injection of a small dose of radioactive iodine usually (>90%) results in normal thyroid function after treatment, without the need for continued medication. You can learn more about Radioactive Iodine (Feline I-131) treatment here.
