Wegovy in the UK: The Current Picture
Wegovy contains semaglutide and is a prescription-only medicine manufactured by Novo Nordisk. It has received authorisation in the UK for specified weight management indications, and NICE has issued guidance supporting its use for patients who meet specific eligibility criteria. The UK marketing authorisation specifies the clinical indication for Wegovy. NHS prescribing is subject to additional NICE and NHS eligibility criteria and local service arrangements, which are separate from the licensed indication.
According to the NHS, Wegovy is a prescription-only medicine that should always be used under the supervision of a qualified healthcare professional, alongside a reduced-calorie diet and increased physical activity.
NHS access and eligibility depend on the healthcare system and local arrangements applicable to where you live. This blog is written for patients in South Wales, where NHS arrangements are governed by NHS Wales rather than NHS England. For the most up-to-date information on NHS access in your area, speaking with your GP is recommended. For a fuller picture of the NHS versus private prescribing landscape, our guide on Mounjaro and NHS access covers the key differences in detail, many of which apply equally to Wegovy.
How Wegovy Works
Semaglutide is a GLP-1 receptor agonist that helps regulate appetite and food intake, contributing to weight loss when used alongside a reduced-calorie diet and increased physical activity. It is injected once weekly using a pre-filled auto-injector pen.
The dose is increased gradually over 16 weeks from 0.25 mg once weekly to the 2.4 mg maintenance dose. The current UK Summary of Product Characteristics (SmPC) also describes the possibility of increasing to 7.2 mg once weekly for certain adults with obesity where needed, after at least four weeks on the 2.4 mg dose. Dose escalation may be delayed or adjusted by the prescriber if clinically appropriate, including where significant gastrointestinal symptoms occur.
What the Clinical Evidence Shows for Wegovy in the UK
| Trial | Key Finding | Duration |
|---|---|---|
| STEP 1 | Average weight loss of approximately 14.9% in adults without type 2 diabetes | 68 weeks |
| STEP 2 | Average weight loss of approximately 9.6% in adults with type 2 diabetes | 68 weeks |
| STEP 3 | Average weight loss of approximately 16.0% when combined with intensive behavioural therapy alongside reduced-calorie diet and increased physical activity | 68 weeks |
| STEP 4 | Participants who continued semaglutide after the initial treatment period continued to lose weight, while those switched to placebo regained weight | 48 weeks |
What Affects How Well Wegovy Works for You?
Whether you have type 2 diabetes
The STEP trial data shows consistently stronger average weight loss in patients without type 2 diabetes compared to those with it. This does not mean Wegovy is not effective for patients with type 2 diabetes, but expectations should be calibrated accordingly.
Lifestyle changes alongside treatment
Wegovy is intended to be used alongside a reduced-calorie diet and increased physical activity. The STEP 3 trial, which combined semaglutide with intensive behavioural therapy alongside dietary and activity changes, produced the highest average weight loss of any arm of the programme at approximately 16.0%.
Dose progression and adherence
Treatment response varies between individuals. Dose escalation should follow the authorised dosing schedule and may be delayed or adjusted by the prescriber if clinically appropriate, including where significant gastrointestinal symptoms occur. The STEP 4 data showed that participants who continued semaglutide after an initial treatment period continued to lose weight, while those switched to placebo regained weight.
Wegovy versus Mounjaro: which is right for you?
Both Wegovy and Mounjaro are prescription-only medicines licensed for weight management in the UK. Wegovy contains semaglutide and acts on the GLP-1 receptor, while Mounjaro contains tirzepatide and acts on both GIP and GLP-1 receptors. Clinical trial evidence has shown substantial weight loss with both medicines, but results from different trials are not directly comparable. Treatment choice depends on the individual’s clinical circumstances and should be discussed with a prescriber. Our guide on switching between Mounjaro and Wegovy covers the key differences between the two treatments in more detail.
