I-131 Radiation Therapy: What You Need to Know About Treating Feline Hyperthyroidism

​If your cat has been diagnosed with hyperthyroidism, you may feel overwhelmed by the treatment options. At our hospital, VSP, we are proud to offer a gold-standard solution: I-131 therapy, the most effective, safe, and non-invasive treatment available for feline hyperthyroidism.

How Does Radioactive Iodine Therapy (I-131) Work?
I-131 therapy uses a single injection of radioactive iodine to target and destroy overactive thyroid tissue while sparing healthy cells. This approach restores normal thyroid function without the need for surgery or daily medications. It’s highly effective, with success rates exceeding 95%. Most cats show noticeable improvements in just a few weeks .

What to Expect During Treatment
    •    Pre-Treatment Evaluation: Includes blood tests, imaging, and a thorough health assessment to ensure your cat is a suitable candidate.
    •    Hospitalization: Your cat will stay in a dedicated ward for a few days to ensure radiation safety.
    •    Single Injection: The treatment involves one quick, painless subcutaneous injection of I-131.
    •    Monitoring and Discharge: Once radiation levels fall to safe limits, your cat will return home healthier and happier .

Why Choose I-131 Therapy? Compared to other treatments like medication or surgery, I-131 offers significant advantages:
    •    No Daily Medications: Eliminates the struggle of giving pills to your cat.
    •    Minimally Invasive: No anesthesia or surgical risks.
    •    Long-Term Solution: One treatment often cures hyperthyroidism for life.
    •    Cost-Effective: Over time, I-131 is more affordable than ongoing medication or repeated procedures.
    •    Preserves Healthy Tissue: Targets only the overactive thyroid cells.
    •    Veterinarian-Recommended: Preferred by veterinary endocrinologists as the gold standard .
