How long does Liothyronine Sodium stay in your body?

The elimination half-life of liothyronine sodium is about 2-1/2 days (the label's "biological half-life") — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. Liothyronine IS the active thyroid hormone T3 itself — it is not a prodrug, and it has no active metabolite that outlasts it (T3 is degraded by deiodination to inactive diiodothyronine). Note that T3 is the shorter-lived hormone; the related, separate drug levothyroxine (T4) has a longer half-life and is peripherally converted to T3, but that is a different drug, not a metabolite of liothyronine. The label gives a single "biological half-life" and does not break it into distinct distribution/terminal phases, nor does it state how the half-life changes in older adults or in kidney or liver impairment.

It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.
