Thyroid (Pork)

Pronounced

"THYE-roid"

Uses

Thyroid hormone is used to treat underactive thyroid (hypothyroidism). It is a natural product made from animal thyroid glands (usually a pig's). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone is important for maintaining normal mental and physical activity. In children, having enough thyroid hormone is important for normal mental and physical development.

This medication is also used to treat other types of thyroid disorders (such as certain types of goiters, thyroid cancer) and also to test for thyroid function.

This medication should not be used to treat infertility unless it is caused by low thyroid hormone levels.

Older adults should discuss the risks and benefits of this medication with their doctor or pharmacist.
