What are the uses of this product?

Thyroid hormone is used to treat underactive thyroid (hypothyroidism). It is a natural product made from animal thyroid glands (usually a pig's).

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.
