Mounjaro and Ozempic are prescription medicines used alongside diet and exercise to help control blood sugar (glucose) levels in adults with type 2 diabetes. Ozempic is also approved to lower the risk of a major cardiovascular event (like a heart attack or stroke) in patients with type 2 diabetes. Mounjaro has not yet received this indication, although studies are ongoing.
In a large, 2024 retrospective study in adults with overweight or obesity and treated for type 2 diabetes, Mounjaro led to at least a 5% weight loss within one year in 81.8% of adults compared to 66.5% of those using Ozempic.
