Iodine 131 treatment

Radioactive iodine (I 131) can be used to provide a safe and effective cure for hyperthyroidism, which is a common disorder of older cats.  The radioactive iodine is taken up by active thyroid tissue, but not by other body tissues, selectively destroying the affected thyroid tissue. A single injection of I 131 is curative in around 95% of cases, and in those cats where hyperthyroidism persists, treatment can be repeated.

Dr. Morna Hill manages our iodine 131 facility. Morna is an enthusiastic feline practitioner, currently studying for her Australian College Feline Medicine exams. If you have any queries in regards to the disease hyperthyroidism, iodine 131 treatment or any other challenging feline medical conditions, please contact Dr. Morna.

A single treatment of iodine 131 is often curative and has no serious side effects.  Given by injection, the treatment is painless and does not require an anaesthetic. Precautionary measures are required to protect our staff during the treatment period.  For this reason the treatment can only be carried out at an approved facility, and the cat must be kept in the licensed hospital until the radiation levels have fallen to within acceptable limits.  This means cats must be kept in hospital for 5-7 days following treatment. 

Spacious cattery style accommodation is provided in our radioactive iodine ward. Ourvets is an approved and licensed facility for this form of treatment.

We also provide a referral service for other veterinary clinics.  Please read our FAQ below and feel free to contact us if you have any further questions.
