Methimazole Compound

• Methimazole is an anti-thyroid agent.

• The thyroid gland takes in iodine that is digested and turned into the thyroid hormones T4 and T3.

• The thyroid hormone is responsible for regulating the body's metabolism.

• When the thyroid gland produces too much T3 and T4, weight loss, abnormal appetite, and heart problems occur.

• High levels of T3 and T4 are fairly common in older cats.

• Methimazole is used to treat...

• hyperthyroidism, or an overactive thyroid gland

• Methimazole works by blocking iodine's entry to the thyroid gland.

• Without iodine, the thyroid gland cannot produce T4 and T3.
