Ozempic vs Wegovy is a common search because both brand names are tied to semaglutide. The important distinction is that “same active ingredient” does not mean “same label, same approved use, same device, or interchangeable prescription.” (Ozempic PI; Wegovy PI)
This guide compares label facts only. It does not tell you which medication to take, whether to switch, or how to change a dose.

Every row above comes from a label, not from a comparison of how well either one works.
Same active ingredient, different approved uses
Ozempic’s current label says it is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. The same label also lists risk-reduction indications for major adverse cardiovascular events in adults with type 2 diabetes and established cardiovascular disease, and for kidney disease progression and cardiovascular death in adults with type 2 diabetes and chronic kidney disease. (Ozempic PI)
Wegovy’s current label says Wegovy injection is indicated with reduced-calorie diet and increased physical activity to reduce major adverse cardiovascular event risk in adults with established cardiovascular disease and obesity or overweight, to reduce excess body weight and maintain weight reduction long term in specified adults and adolescents, and to treat noncirrhotic MASH with moderate to advanced liver fibrosis under accelerated approval. (Wegovy PI)
Those label differences are why a prescriber decision matters. A comparison article can describe approved uses; it cannot decide which approved use applies to you.
Injection routine similarities
Both labels describe weekly subcutaneous injection for the injectable product and list the abdomen, thigh, or upper arm as injection regions. The Ozempic label says to use a different injection site each week when injecting in the same body region. The Wegovy label says to rotate injection sites with each dose. (Ozempic PI; Wegovy PI)
If you are tracking a weekly routine, those shared categories matter: date, product, prescribed dose, and injection body region. For the broader routine, see the GLP-1 injection guide.
Product presentation is different
Ozempic’s current prescribing information lists multi-dose single-patient-use pens. The dose-count table is why people ask how long a pen lasts. See How long does an Ozempic pen last? for that label-based arithmetic. (Ozempic PI)
Wegovy’s current prescribing information covers Wegovy injection and Wegovy tablets. This guide does not compare tablet routines or suggest switching between presentations. Use the current label and your prescriber’s instructions for the exact product you have. (Wegovy PI)
Missed-dose language is product-specific
Do not assume a missed-dose rule is interchangeable just because two products contain semaglutide. The two labels use different windows, and Wegovy’s injection and tablet instructions differ from each other. The missed GLP-1 dose guide reproduces both labels’ wording verbatim, with attribution, and explains why Dosley records the event instead of telling you what to do. (Ozempic PI; Wegovy PI)
After the prescription decision
Dosley does not help you choose between these two. It helps once the choice is made and the weekly routine starts. Which brand, which pen strength, which day, which body region. If you switch from one to the other, the injection dates on either side of the change are worth having in front of you at the next appointment.
