Why this page exists separately from semaglutide
Searchers use the brand name when they want a fast answer. The source-level answer still belongs to semaglutide, but an exact Wegovy page helps connect the brand query to the evidence profile and calculator.
Wegovy, semaglutide, and the five-week estimate
With a one-week half-life, five half-lives is about 35 days. That is a population-level model, not a guarantee of when a person will feel effects stop or when clinical decisions should change.
