Wegovy vs Ozempic UK: Which Semaglutide Is Right for You?
Both Wegovy and Ozempic contain the same active ingredient — semaglutide — but they are very different products designed for different purposes. If you’re considering semaglutide treatment in the UK, understanding the key distinctions between these two medications is essential for making the right choice with your prescriber.
What Is Wegovy?
Wegovy (semaglutide 2.4mg) is a GLP-1 receptor agonist specifically approved for chronic weight management in adults. It is manufactured by Novo Nordisk and was approved by the MHRA for use in the UK in 2023. Wegovy is indicated for adults with a BMI of 30 or above, or 27 or above with at least one weight-related condition such as type 2 diabetes, high blood pressure, or high cholesterol. It is administered as a weekly subcutaneous injection and is titrated from 0.25mg up to the full maintenance dose of 2.4mg over a 16-week period. Wegovy is now available on the NHS in England through specialist weight management services, though private access remains more immediately available for most patients.
What Is Ozempic?
Ozempic (semaglutide 0.5mg, 1mg, or 2mg) is also manufactured by Novo Nordisk, but it is licensed specifically for the treatment of type 2 diabetes in adults. It helps improve blood sugar control and has been shown in clinical trials to significantly reduce the risk of cardiovascular events in people with diabetes. While Ozempic also causes weight loss as a side effect, it is not licensed for weight management in the UK. This means any use of Ozempic purely for weight loss is considered “off-label”. It is available on NHS prescription for eligible diabetes patients and can also be prescribed privately. The maximum approved dose of Ozempic is 2mg weekly.
Key Differences Between Wegovy and Ozempic
Approved Uses
The most fundamental difference is the licensed indication. Wegovy is approved for weight management; Ozempic is approved for type 2 diabetes. Using Ozempic off-label for weight loss is practised by some private clinics, but this approach carries regulatory and clinical considerations that should be discussed with a qualified prescriber.
Dosing
Wegovy reaches a maximum maintenance dose of 2.4mg weekly, while Ozempic’s maximum approved dose is 2mg weekly. The higher dose in Wegovy is thought to contribute to greater weight loss outcomes. Both medications follow a gradual titration schedule to minimise side effects such as nausea and gastrointestinal discomfort during the first weeks of treatment.
Pricing
In the UK private market, Wegovy typically costs between £200 and £350 per month, depending on the provider and dosage level. Ozempic pricing through private providers is broadly similar, though some clinics may offer it at a slightly lower cost. NHS pricing is not applicable for weight loss purposes, as Wegovy access through the NHS is still limited and Ozempic is only NHS-prescribed for diabetes.
Availability
Both medications have experienced supply shortages in the UK since 2023 due to global demand. However, Wegovy availability has been improving as Novo Nordisk increases production capacity. Ozempic shortages remain a significant concern for people with type 2 diabetes who rely on it for blood sugar management — this is one reason why NHS guidelines discourage off-label use of Ozempic for weight loss when it can affect supply for diabetes patients.
Which Should You Choose?
The choice between Wegovy and Ozempic should always be made in consultation with a qualified prescriber. As a general guideline:
- If your primary goal is weight loss and you do not have type 2 diabetes, Wegovy is the appropriate choice as it is specifically licensed for this purpose
- If you have type 2 diabetes and also wish to lose weight, Ozempic may be prescribed as it addresses both blood sugar control and supports weight reduction
- If you have access to NHS weight management services, Wegovy may be available to you through that route
- For private treatment, discuss both options with your prescriber, who will recommend the most suitable medication based on your health profile

Frequently Asked Questions
Can I use Ozempic for weight loss in the UK?
Ozempic is not licensed for weight loss in the UK, but some private clinics may prescribe it off-label for this purpose. This should only be done after a thorough medical consultation. Wegovy is the licensed and recommended option for weight management.
Is Wegovy the same as Ozempic?
Both contain semaglutide, but they are different products with different licensed indications, dosing regimens, and approved maximum doses. Wegovy (2.4mg) is for weight management; Ozempic (up to 2mg) is for type 2 diabetes.
How long does it take to see results with Wegovy?
Clinical trials show meaningful weight loss typically begins within 12–16 weeks of starting Wegovy. The STEP 1 trial demonstrated an average weight loss of approximately 15% of body weight over 68 weeks in patients who completed the full titration schedule.
Which is more effective for weight loss — Wegovy or Ozempic?
Clinical evidence suggests Wegovy produces greater weight loss than Ozempic due to its higher dose (2.4mg vs 2mg maximum). However, individual responses vary, and the most effective medication is always the one prescribed and monitored by a qualified clinician for your specific situation.
