Following a diagnosis of hypothyroidism, treatment involves thyroid hormone replacement. There are many options in this area, including:1
Administration of T3 therapy only can lead to peaks and troughs of thyroid hormone levels immediately after and preceding therapy. As T4 is generally more stable than T3 and can be broken down to the biologically more active T3, most endocrinologists will prescribe T4 therapy for patients with hypothyroidism, in order to maintain acceptable levels of both T3 and T4.

Following a diagnosis of hyperthyroidism, treatment usually involves counteracting the production or effects of excessive thyroid hormone production either pharmacologically, radiotherapeutically, or surgically.
Antithyroid drugs typically make it more difficult for the body to manufacture thyroid hormones by affecting its ability to use iodine.2 There are three key antithyroid drugs:

In many countries, including the USA, radioactive iodine treatment/ablation is a common procedure for most people with Graves’ disease and hyperthyroidism.4 A single dose of Iodine-131 is administered and subsequently accumulates in the thyroid, damaging and destroying the thyroid cells and thereby modifying thyroid function. Following radioactive iodine treatment, patients will usually require thyroid hormone replacement therapy.
Thyroidectomy is often considered the last choice in the US for treating an overactive thyroid.5 However, surgical treatment may be recommended if:
