What is Levothyroxine?
Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It is commonly prescribed to treat hypothyroidism, a condition where the thyroid gland does not produce enough hormones.
This medication helps restore normal hormone levels, supporting metabolism, energy production, and overall body function.
How Levothyroxine Works
Levothyroxine replaces or supplements the natural thyroid hormone in the body. Once absorbed, it is converted into the active hormone (T3), which regulates:
- Metabolism
- Heart rate
- Body temperature
- Energy levels
By restoring hormone balance, it helps relieve symptoms of hypothyroidism.

Doctors commonly prescribe levothyroxine for:
