Thyroid Medication question?

A friend of mine was just given CYTOMEL for an underactive thyroid.
Has any one been given this medication? I was told you need a T4 & T3 or just a T4. But never a T3 by itself…any thoughts?

    Liothyronine, a thyroid hormone, is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone (T3- Triiodothyronine). Thyroxine (T4) is a prohormone and a reservoir for the active thyroid hormone triiodothyronine (T3), which is about four times more potent.
