Wegovy has quickly become a key treatment option in obesity management, particularly for adults living with excess weight and health conditions linked to obesity.
With recent price increases for Mounjaro®, another GLP-1 medication, many patients and healthcare providers are now turning to Wegovy as a strong alternative.
Clinical research shows that Wegovy can deliver significant weight loss results, often comparable to those seen with Mounjaro, making it one of the most effective options currently available.
Recent news and clinical trial data reveal that higher doses of Wegovy specifically at 7.2 mg weekly, have led to average weight loss of around 21% in adults with obesity, with approximately one-third of participants achieving a weight loss of 25% or more over 72 weeks. This is notably greater than the 15% average weight loss seen at the standard 2.4 mg dose.
Latest Clinical Data on Higher Doses
The 2025 STEP UP phase 3b trial evaluated semaglutide at both 7.2 mg and 2.4 mg weekly doses versus placebo in people with obesity who did not have diabetes. The results indicated a clear dose-response effect:
- Mean weight loss was 21% at 7.2 mg, compared to 17.5% at 2.4 mg, and much lower with placebo.
- Specifically, 51% of those on 7.2 mg lost at least 20% of their body weight, and 33% achieved a reduction of 25% or more.
- For 2.4 mg, 35% lost 20% or more, and 17% achieved 25% or greater weight loss.
Regulatory and Safety Considerations
- Novo Nordisk has announced plans to seek regulatory approval for the higher 7.2 mg dose in the EU and other regions in late 2025.
- Safety and tolerability of the 7.2 mg weekly dose were consistent with the known profile of semaglutide, with gastrointestinal side effects remaining most common, except for a low discontinuation rate for adverse effects (about 3%).
- These findings extend the potential of Wegovy for people requiring greater degrees of weight loss, emphasising the dose-dependent effect of semaglutide GLP-1 therapy.
Comparing New findings with Mounjaro
At higher doses (7.2 mg), Wegovy has demonstrated weight loss outcomes that closely mirror those achieved with Mounjaro. Clinical data show an average 21% reduction in body weight over 72 weeks with Wegovy, with around half of patients reaching at least 20% weight loss. By comparison, Mounjaro studies report average reductions of up to 22–23% at higher doses over a similar treatment duration. While Wegovy’s 7.2 mg dose remains under regulatory review and is not yet standard practice, these findings highlight that patients considering a switch may be able to achieve results that are highly comparable to those seen with Mounjaro, offering another strong option in pharmacological obesity management.
Head-to-head style snapshot (72-week outcomes)
In conclusion, if you are considering switching from Mounjaro to Wegovy, now is an excellent opportunity. Wegovy offers a highly effective alternative for weight management with similar clinical results, and - importantly - comes at a considerably lower price, especially as Mounjaro prices are set to rise sharply in the UK from September 2025. Choosing Wegovy can help maintain your weight loss goals while making your treatment more affordable.

When new medical studies are released, they can feel full of numbers and complex terms. At SheMed, our role is to help you understand what they really mean for you, your health, and your future.
Recently, Novo Nordisk released the results of the STEER study, one of the most significant pieces of research yet on GLP-1 medicines like Wegovy. And the findings show something powerful: Wegovy is not only about weight loss, it’s also about heart health.
The Big Picture: What the STEER Study Looked At
The STEER study explored how GLP-1 medicines affect heart health in people living with Overweight or Obesity and established cardiovascular disease (but without diabetes).
Researchers compared Wegovy (Semaglutide 2.4mg) with Tirzepatide (Mounjaro). They focused on the risk of serious heart problems, what doctors call “major adverse cardiovascular events” (MACE). These include:
- Heart attack
- Stroke
- Death from heart disease
What They Found
The results were striking:
- For people who stayed on treatment without big gaps, Wegovy reduced the risk of heart attack, stroke, or cardiovascular death by 57% more than Mounjaro.
- When looking at all treated people, even those with breaks in care Wegovy still showed a 29% reduction in these serious events overall.
In short, Wegovy is not only helping people lose weight, it is also showing clear cardiovascular protection, especially when used consistently.
Why This Matters for You
We’ve always known GLP-1 medicines are powerful tools for weight loss, but the STEER study highlights something even bigger: they can also protect your heart. For anyone living with Obesity and cardiovascular disease, this is game-changing.
It also reinforces an important truth - long-term commitment matters most. The people who saw the greatest benefits were those who stayed consistent with their medication. That’s why at SheMed, we design every part of our programme to keep you supported, motivated, and engaged for the long run.
The SheMed Difference: Seeing the Bigger Picture
Medication is only one part of your health journey. At SheMed, we combine Wegovy with wraparound care:
- Regular blood tests to track key markers like cholesterol, blood sugar, and liver health.
- Weekly check-ins and app reminders to help you stay on track.
- Education and content designed specifically for women, covering sleep, hormones, activity, and nutrition.
- Proactive Side effect care and support to keep you comfortable and supported as your body adjusts.
This holistic approach matters because weight loss is just one marker of progress. By running blood tests before starting the programme, at 6 months, and 12 months, we can show you the deeper changes happening inside your body, improvements in cholesterol, blood sugar, and overall metabolic health.
It means you’ll see the true value of GLP-1s, not just in how you look or feel, but in the measurable ways your health is improving and your risks are reducing.
Why Wegovy Through SheMed Makes Sense
At SheMed, we’ve worked hard to make Wegovy accessible and affordable. With static, transparent pricing across doses, our members know exactly what they’re paying. That means no hidden surprises and no price hikes as you move up through titration.
When you combine that cost benefit with the evidence from STEER that Wegovy offers not just weight loss but cardiovascular protection the case for choosing Wegovy through SheMed becomes even stronger.
You’re not just investing in weight management; you’re investing in heart health, future health, and a programme designed to keep you safe and supported every step of the way.
The Future of Health With SheMed
The STEER study is a reminder that the story of GLP-1s is still unfolding and it’s about so much more than weight loss. These medicines are changing how we think about obesity, cardiovascular health, and long-term wellbeing.
At SheMed, we’ll continue to keep you informed as new research emerges, but more importantly, we’ll keep showing you the bigger picture through your own results. With every blood test, every milestone, and every step forward, you’ll see how far you’ve come not just in weight, but in health.
Because at SheMed, you’re not just losing weight. You’re gaining health, protecting your future, and building the strongest version of you.
The recent price rise news of Mounjaro in the UK has been difficult for many people. If you’re feeling worried or uncertain about what this means for your treatment, you’re not alone.
Because of these changes, a growing number of people are now considering alternatives such as Wegovy (semaglutide). Wegovy is often more affordable, and studies have shown that at higher doses it can lead to weight loss of up to 20%.
Still, it’s important to remember that Mounjaro and Wegovy are not the same medication. Each works differently, and switching from one to the other needs careful thought and planning with the right support.
To make things a little easier, we’ve pulled together the key things you should know before making a decision.
Mounjaro vs Wegovy: The Key Differences
- Mounjaro (tirzepatide): Acts on both GLP-1 and GIP receptors, which may make it particularly effective for appetite suppression and glucose control.
- Wegovy (semaglutide): Works only on the GLP-1 receptor, a well-studied pathway for weight management and type 2 diabetes. Recent data suggest that Wegovy at higher doses can deliver average weight loss of around 15–20%, rivalling or even exceeding some reports for Mounjaro.
Because of these differences, there isn’t a direct like-for-like conversion between the two medicines. Instead, clinicians use approximate dose equivalents when making the switch.
Available Doses
Mounjaro is available in the following dose strengths (weekly injections):
- 2.5 mg
- 5 mg
- 7.5 mg
- 10 mg
- 12.5 mg
- 15 mg
Wegovy is available in these weekly dose strengths:
- 0.25 mg
- 0.5 mg
- 1.0 mg
- 1.7 mg
- 2.4 mg (maintenance dose)
Switching Dose Guide
At Shemed, we understand that switching between treatments can feel overwhelming, and many people want clear answers. However, there is no strict dose conversion between Mounjaro and Wegovy. The choice of starting dose when switching should always be made by a qualified healthcare professional, taking into account your current treatment, medical history, and individual response.
⚠️ Important: Please don’t feel you need to figure this out on your own. Do not attempt to switch or calculate equivalent doses without support. Always follow the advice of your prescribing clinician, who will guide you safely through the transition and answer any questions you may have.
Timing the Switch
At SheMed we recommend:
- Wait around 7 days after your last Mounjaro injection before starting Wegovy. This helps to minimise overlapping effects and reduces side-effect risks such as nausea or bloating.
Titration and Side Effects
At Shemed, your clinician will decide which starting dose of Wegovy is most suitable for you. Titration - that is, gradually increasing the dose over time - will be required to minimise side effects and ensure your body adjusts safely. The exact schedule will vary depending on your individual circumstances, and your prescribing clinician will guide you through this process step by step.
Common side effects during the switch can include:
- Nausea
- Bloating
- Diarrhoea or constipation
- Tiredness
These usually improve as your body adjusts, and your clinician will be on hand to support you if side effects persist or feel difficult to manage.
What to Expect After Switching
- Effectiveness: Some patients notice slightly different appetite suppression on Wegovy compared to Mounjaro, due to their differing mechanisms of action.
- No withdrawal symptoms: Stopping Mounjaro does not cause withdrawal, but you may feel a change in appetite control during the transition.
- Follow-up: Your clinician will likely schedule a review monthly after starting Wegovy to monitor your progress and adjust dosing.
Key Takeaways
- Rising Mounjaro prices in the UK mean many people are now considering Wegovy as a cost-effective alternative.
- Wegovy has been shown to deliver up to 20% weight loss at higher doses in recent studies.
- A minimum 7-day gap is typically recommended before starting Wegovy.
- Dose equivalents provide a starting point, but titration is still necessary.
- Always work with your healthcare professional to personalise your transition.
