Wegovy and Ozempic contain the same medicine, semaglutide. The difference is what they are approved for, the dose and how insurance covers them.
The short answer
Wegovy and Ozempic are both semaglutide made by Novo Nordisk. Ozempic is approved to treat type 2 diabetes and reduce heart risk in people with diabetes, up to 2 mg a week. Wegovy is approved for chronic weight management, with a maintenance dose of 2.4 mg a week, and to lower heart risk in people with heart disease and excess weight. Prescribing Ozempic for weight loss alone is off-label.

The short version
Why the weight loss differs
Wegovy’s higher dose and its trials in people without diabetes explain most of the gap. People with type 2 diabetes generally lose less weight on the same medicine.
Side effects
The side effects are the same: nausea, constipation, diarrhoea and fullness, usually easing with time. Doses are increased slowly to limit them.
Which one will I be prescribed?
It depends on your diagnosis, coverage and supply. If you have type 2 diabetes, Ozempic or another diabetes medicine is usual. For weight management without diabetes, Wegovy (or tirzepatide as Zepbound, where available) is the approved option.
