Hyperthyroidism, also know as thyrotoxicosis, occurs when a cat’s thyroid produces excessive amounts of the T3 and T4 thyroid hormones. The condition typically strikes middle-aged or older cats, between the ages of 8 and 13 years, and is often caused by tumors on the thyroid.
The thyroid hormones affect many organ functions and play an important role in regulating metabolism. Hyperthyroidism, therefore, can really wreak havoc on a cat’s overall health.
Fortunately, there are three different treatment options available for cats suffering with hyperthyroidism. These options include surgery, radioactive-iodine therapy, and medication. Your veterinarian will determine which one is right for your cat based on the type of tumor on the thyroid and your cat’s general health.
Hyperthyroidism Medication for Cats
Methimazole is the most commonly prescribed medication for hyperthyroidism in cats. It is an anti-thyroid medication that comes in tablet form. It works to restore normal thyroid levels by interfering with iodine, which is an element that enables the thyroid gland to produce thyroid hormones.
