Hypothyroidism - primary
Treatment
The purpose of treatment is to replace the thyroid hormone that is lacking. Levothyroxine (T4) is the most commonly used medication. However a form of T3 is sometimes used together with thyroxine. A combination of T4 and T3 is also available. Most people feel their best when TSH level is brought into the 1 - 2 mcIU/mL range. People get the lowest dose that effectively relieves their symptoms and brings their blood tests into the normal range.
