Frequently asked
How long does Liraglutide stay in your system?
With a half-life of ≈ 13 h, roughly 97% of a single Liraglutide dose is cleared after five half-lives — about 2.7 days. Repeated dosing accumulates and takes correspondingly longer to clear.
What does a ≈ 13 h half-life mean in practice?
Every 13 h, the remaining amount halves: 100% → 50% → 25% → 12.5%, and so on. The curve above plots exactly this decay for a single dose.
Where does this Liraglutide half-life number come from?
FDA Saxenda label (NDA 206321); plasma half-life ≈ 13 h (once-daily). We cite a primary source for every half-life we publish and version every change.
