Hyperthyroidism is a commonly diagnosed endocrine disease in cats. Current treatment options include long-term use of antithyroid medications, thyroidectomy, and administration of radioactive iodine (‘”I). All 3 of these treatment , modalities are commonly used and effective. Each also has disadvantages. The most commonly used antithyroid medication, methimazole, usually requires daily administration; may cause anorexia, vomiting, and self-excoriation; and less commonly has been associated with hematologic abnormalities, hepatopathies, and bleeding disorders. Thyroidectomy and treatment with “‘1 can provide permanent resolution of hyperthyroidism. Treatment with I3lI, however, may be limited by availability, hospitalization time, and expense. Surgery may be limited by anesthetic risk and concem of iatrogenic hypoparathyroidism.
