Patients who stop using weight loss medications are likely to return to their baseline weight within two years, a new analysis finds. Newer medications, such as Mounjaro and Wegovy, exhibit both more total weight lost and faster weight regain than older medications.

Those who take tirzepatide, the drug sold as Zepbound and Mounjaro, could lose more weight than those who take semaglutide, known as Ozempic and Wegovy, according to new research.

A new study shows that people Zepbound lost about 50% more weight than those using Wegovy. It was the first head-to-head trial of the blockbuster weight-loss medications.
