Ozempic or Wegovy: Understanding the Difference

Both Ozempic and Wegovy are GLP-1 receptor agonists containing semaglutide, but they are distinct licensed medicines and should not be treated as interchangeable without prescriber guidance.

Ozempic (semaglutide for type 2 diabetes)

Ozempic is licensed for the management of type 2 diabetes in adults. It is a once-weekly injectable medicine, typically used alongside diet and exercise and, where appropriate, other diabetes medicines. The dose strengths commonly associated with Ozempic differ from those used in Wegovy — your prescriber and the patient information leaflet supplied with your pen are the definitive references for your specific regimen.

Wegovy (semaglutide for weight management)

Wegovy is licensed specifically for chronic weight management in adults who meet defined clinical criteria, such as a body mass index (BMI) above a set threshold, with or without weight-related health conditions. It is also a once-weekly injectable and is titrated gradually, starting at a lower dose, with the schedule managed by a prescriber. According to the electronic Medicines Compendium (eMC), Wegovy's highest maintenance dose is 2.4 mg weekly — a level not reached with Ozempic in its standard licensed use.

How do they compare to Mounjaro (tirzepatide)?

Mounjaro contains tirzepatide, a different active substance that acts on both GLP-1 and GIP receptors — making it a dual agonist rather than a single GLP-1 agonist like semaglutide. People sometimes ask about the differences between Mounjaro and Wegovy, or explore how Mounjaro and Wegovy compare in terms of studied outcomes — these are genuinely informational questions, and the answer in every case is the same: suitability and choice are decisions for a prescriber, not a search result.

Other medicines sometimes mentioned in similar searches — such as orlistat — work through entirely different mechanisms (orlistat inhibits fat absorption in the gut rather than acting on appetite pathways) and are separate medicines with their own licensed uses. Any comparison between them belongs in a conversation with your prescriber or doctor.

For a broader look at how semaglutide-based and tirzepatide-based medicines sit alongside each other, the Wegovy vs Mounjaro overview covers the key factual points. You can also read a detailed breakdown on whether Wegovy or Mounjaro may suit different situations — always with the understanding that the right choice is your prescriber's to make.

GLP Trackr is built for people already on a GLP-1 medicine — whether that is Wegovy, Mounjaro, or another prescribed treatment. The most immediately useful feature for someone starting out is dose and injection logging: every weekly shot is recorded with the date, dose strength, and injection site, so you always know exactly where you are in your schedule and which site to rotate to next.

Beyond logging shots, the app's side-effect tracker lets you note how you feel after each dose — nausea, fatigue, any changes in appetite — and builds a picture over time that is genuinely useful to bring to your next prescriber appointment. The insights tools then surface patterns across your dose history, weight, food, and wellbeing data, so you can see what is actually shifting week by week.

GLP Trackr supports both Wegovy and Mounjaro users, and the tracking features work the same way regardless of which medicine you have been prescribed. If you are partway through your titration and want a clearer record of your journey so far, the app's 7-day free trial is a straightforward way to start.

Any questions about whether your current prescription is the right one for you — or whether switching between medicines makes sense — belong with your prescriber or doctor, who knows your full clinical picture. GLP Trackr helps you record your experience clearly so those conversations are better informed, but it is not a substitute for professional medical advice.
