Frequently Asked Questions

What is the success rate after treatment with RadioIodine (I-131)?

95-98% of cats are successfully treated with only one injection under the skin and do not need any follow-up treatments. Once the patient has been released from the Thyro-Cat facility, he (or she) is monitored by the referring veterinarian to assure that there is appropriate response to the therapy .

Are there any side effects from treatment?

There are almost no side effects from this treatment. There may; however, be a period of readjustment, due to the return of normal thyroid function, and your cat may be quieter and may eat less food. Rarely, a sore throat or change in voice may also occur. In rare situations, hypothyroidism may occur. This condition can easily be corrected with a thyroid supplement, if needed.

What if my cat is already taking Tapazole?

If the patient is currently on Tapazole, the medication should be stopped at least seven days prior to the I-131 therapy. Most cases require a thyroid blood test seven days after stopping the administration of the medication.

Can I visit my cat after the I-131 has been injected?

Unfortunately, clients are not allowed to have direct contact with their pets after the I-131 has been injected. This is due to radiation regulations as mandated by the State Department of Health and the Nuclear Regulatory Commission.

Can I remove my cat from the therapy facility before the end of the treatment period?

No pet can be removed from the facility until the level of radioactivity has decreased to a level which has been deemed to be safe by our radiation safety officer, and as mandated by the State Department of Health and the Nuclear Regulatory Commission.

Is my cat too old for I-131 treatment?

Cats of any age may be treated, as long as there are no other life-threatening medical conditions present. Thorough screening tests are performed to minimize any risks. Even cats 17 to 20 years old have been successfully treated.
