Does your Cat suffer from Hyperthyroidism?  Tired of fighting to get in medication?

We have the answer

Feline Radioactive Iodine Therapy

Also known as:   I - 131

  • I-131 is a calculated injection of radioactive iodine administered subcutaneously or under the skin in a veterinary hospital. It is considered the treatment of choice for Feline Hyperthyroidism by experts.
  • How it works: The thyroid gland concentrates iodine. After administration of I-131, the thyroid gland takes up the radioactive iodine, which emits radiation particles that selectively destroy the abnormal thyroid tissue without damaging other tissue.
  • Feline Hyperthyroidism (FHT) is the most common endocrine disorder in US middle age to older cats (up to 10% of cats greater than 10 yrs old and up to 11.4% of older cats worldwide). It is a relatively recent disease that was first described around 1979-1980. I-131 therapy began in the early 1990s. Treatment depend on many factors some such as: age, comorbidities, cost, and availability of treatment options.

I-131 Advantages:

  • No anesthesia is required
  • No daily medication
  • Does not destroy healthy tissue
  • Does not damage other tissue or organs, including the parathyroid glands
  • Returns thyroid function to normal usually within 1 to 3 months

I-131 Disadvantages:

  • Hospitalization (3-5 days) with no owner visits and only signed off trained staff following Isolation SOP to attend to patient
  • 2 weeks “house arrest” for cats once discharged with only short cuddling by owners; can’t be around pregnant women or children up to 16 years of age for the 2 weeks.
  • Litter must be either flushed daily or collected and stored for 3 months before disposing into garbage
  • Up front cost is high but no additional thyroid blood tests over the years or medication charges
