What a half-life chart means
A conceptual model of decay, with its assumptions and limits made visible.
A half-life is a model parameter
This conceptual chart starts at an arbitrary 100% and halves once per illustrative interval. The horizontal axis counts half-lives, not calendar days. No drug, personal regimen or individual concentration is modeled.
Illustrative fraction = 0.5number of half-lives. Absorption, formulation, repeated administration and individual differences can make a real time course more complicated. Neither symptoms nor a safe restart or dose time can be read from this chart.
The Wegovy label, section 12.3 illustrates why pharmacokinetic context is product specific. Source checked November 12, 2026.
