What is Liothyronine?
Liothyronine is a prescription thyroid medication that contains a synthetic form of triiodothyronine (T3), an active thyroid hormone.
It is used to treat thyroid hormone deficiencies, especially in patients who need direct T3 supplementation rather than or alongside T4 therapy.
How Liothyronine Works
Liothyronine works by replacing or supplementing the natural T3 hormone in the body. T3 is the active thyroid hormone responsible for regulating:
- Metabolism and energy production
- Heart rate
- Body temperature
- Brain and nervous system function
Because it is active immediately, liothyronine works faster than T4-only medications.
Conditions Treated with Liothyronine
Doctors may prescribe liothyronine for:
- Hypothyroidism (low thyroid hormone levels)
- Thyroid hormone replacement therapy (when T4 alone is not sufficient)
- Certain cases of thyroid cancer management
- Diagnostic thyroid suppression tests
- Combination therapy with levothyroxine
Liothyronine Dosage & How to Take It
- Taken once or multiple times daily depending on prescription
- Commonly starts with a low dose (e.g., 5–25 mcg)
- Should be taken on an empty stomach
- Take at the same time each day for consistency
Dosage must be carefully adjusted based on thyroid function tests.
