Levothyroxine

Liothyronine and levothyroxine are key medications for managing hypothyroidism, with distinct differences in use and action. Levothyroxine, the synthetic form of thyroxine (T4), is favored for its stability and ease of once-daily dosing. Liothyronine, a synthetic triiodothyronine (T3), offers a rapid response but necessitates frequent dosing due to its shorter half-life. The choice between them depends on individual needs and medical conditions, with levothyroxine often preferred for its predictability. However, some patients may benefit from a combination of both, requiring close monitoring to achieve optimal thyroid hormone levels.
