Felimazole is used in the treatment of hyperthyroidism in cats. This is a condition when the thyroid gland is producing too much thyroid hormone. Felimazole blocks part of the pathway involved in making this thyroid hormone and so reduces the amount of thyroid hormone circulating in the body. Thyroid hormone, also called thyroxine, up regulates the metabolism causing a faster heart rate, an increased appetite and weight loss amongst other signs. Giving Felimazole at a dose that suppresses the hormone will reduce these signs.
