Frequently asked
How long does Cagrilintide stay in your system?
With a half-life of ≈ 7–8 days, roughly 97% of a single Cagrilintide dose is cleared after five half-lives — about 37.5 days. Repeated dosing accumulates and takes correspondingly longer to clear.
What does a ≈ 7–8 days half-life mean in practice?
Every 7–8 days, 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 Cagrilintide half-life number come from?
Cagrilintide review (Cardiology in Review 2023, PMID 36883831); half-life ≈ 7–8 days. We cite a primary source for every half-life we publish and version every change.
