Liothyronine is a synthetic form of the thyroid hormone triiodothyronine (T3) used in hormone replacement therapy to treat hypothyroidism and other thyroid-related conditions. It helps restore normal thyroid function by supplementing low levels of T3, which is crucial for regulating metabolism, energy production, and overall cellular function. Liothyronine is typically prescribed when patients do not respond adequately to levothyroxine (T4) alone. Administered orally, it helps alleviate symptoms such as fatigue, weight gain, depression, and cognitive issues, promoting overall well-being and metabolic health.
