Wegovy is semaglutide dosed for chronic weight management, the same molecule as Ozempic but typically titrated to a higher maintenance dose of 2.4 mg. It shares semaglutide's roughly 7-day half-life, the longest of the common GLP-1 medications.
A single 2.4 mg dose takes about five weeks to fall to a few percent of its starting level, given the week-long half-life. With weekly dosing it builds toward steady state over roughly four to five weeks, which is why effects persist for weeks after a missed or final dose rather than stopping abruptly.
