Hypothyroidism, or an underactive thyroid, is treated with thyroid medication. Levothyroxine (Synthroid, Levoxyl, Levothroid, etc), a synthetic thyroid hormone, is most commonly used. Levothyroxine is T4 which is the long-acting storage form of thyroid hormone. This medication replaces the hormone from your thyroid.

Hypothyroidism is caused by an lack of adequate production and secretion of the thyroid hormone, a patient can often supplement the normal body's production of the hormone by injesting the hormone in pill form. Most patients are given T4  in a weight-based dose (1.6 mcg/kg) and because it administers something naturally produced by the body, there are minimal side effects or allergic reactions. However, symptoms associated with hypothyroidism and hyperthyroidism may been seen is patients are taking too much or too little thyroid hormone. It is important for patients to work closely with their thyroidologist to determine the correct dose of thyroid hormone.
