What Ozempic and Wegovy Have in Common — and How They Differ
Both Ozempic and Wegovy contain semaglutide, a GLP-1 receptor agonist that acts on appetite-regulating pathways in the brain and slows gastric emptying. That shared mechanism is why the two names are so often used interchangeably in everyday conversation — but from a regulatory and clinical standpoint, they are separate products with separate licences.
The key differences
- Licensed indication: Ozempic is licensed for the management of type 2 diabetes; Wegovy is licensed specifically for chronic weight management in adults who meet certain criteria. Your prescriber determines which is appropriate for you.
- Dose range: Wegovy reaches a maintenance dose of 2.4 mg weekly. Ozempic is used at lower doses in its diabetes indication. Both start at a lower dose and are adjusted over time — always under prescriber guidance.
- Pen device and presentation: The two products are supplied in different pre-filled pen devices, even though the active substance is the same.
Because the underlying molecule is identical, people sometimes encounter the name Ozempic when researching Wegovy, or vice versa. If you have been prescribed Wegovy, your treatment is governed by the Wegovy licence, dosing schedule, and patient information — not Ozempic's. Any questions about which product you have been given, or why, are best directed to your prescriber or doctor.
Semaglutide is also the active substance in Rybelsus, an oral (tablet) formulation used in type 2 diabetes management — another related but distinct product.
For a detailed factual comparison of semaglutide-based medicines and tirzepatide (the active substance in Mounjaro), see our page on how Ozempic and Mounjaro compare, or read more about whether Ozempic and Wegovy are the same medicine. You can also explore whether Ozempic and Mounjaro are the same for further context on these two different active substances.

Tracking Your Wegovy Journey with GLP Trackr
Whichever semaglutide product you have been prescribed, staying consistent with your weekly injection schedule and understanding how your body is responding are two of the most valuable things you can do on your journey. GLP Trackr is built specifically for people already taking Wegovy or Mounjaro, and it starts with dose and injection logging — recording each shot, the date, dose strength, and site so you always have a clear record of where you are in your treatment.
Beyond logging injections, the app's side-effect tracker lets you note how you feel day to day — nausea, fatigue, changes in appetite — and surfaces patterns over time. That kind of structured record can be genuinely useful to bring to your next prescriber appointment, so your healthcare professional has a clear picture of your experience rather than relying on memory alone.
GLP Trackr also brings together weight tracking, food logging, and daily check-ins in one place, so your progress is visible as a whole rather than scattered across notes and spreadsheets.

GLP Trackr provides general information and tracking tools — it is not a substitute for guidance from your prescriber or doctor. If you have questions about which medicine you have been prescribed or how to take it, always follow your prescriber's instructions and the patient information leaflet supplied with your pen.

Frequently asked questions.
Ozempic and Wegovy both contain semaglutide, but they are separate prescription products with different licences. Ozempic is licensed for type 2 diabetes management; Wegovy is licensed for chronic weight management. Your prescriber determines which is appropriate for you.
Switching between products or using one in place of the other is a clinical decision for your prescriber, not something to do independently. They differ in licensed indication, dose range, and pen device. Always follow your prescriber's instructions and the patient information leaflet for the product you have been given.
Both contain semaglutide, a GLP-1 receptor agonist, so they share the same mechanism of action — acting on appetite-regulating pathways and slowing gastric emptying. However, they are used at different doses and for different licensed purposes.
The active substance is the same molecule in both products. The differences lie in the licensed indication, the dose range (Wegovy reaches 2.4 mg weekly for weight management), and the pen device used. Your prescriber or the patient information leaflet for your product is the best source of detail.
Yes. GLP Trackr is built for people already prescribed Wegovy or Mounjaro. It lets you log doses, injection sites, side effects, weight, and food in one place, and surfaces patterns you can discuss with your prescriber.
