Switching FAQs
In practice, this means Wegovy is now a more cost-effective GLP-1 option for weight management in the UK.
We know changes like this can feel unexpected and lead to frustration. Our priority is to help you continue your weight-loss journey with minimal disruption and find the treatment that best supports your health goals and fits your lifestyle. Our medical team is always on-hand to advise on the best option for you.
Switching medications is a normal and common occurrence — it’s something medical professionals recommend regularly for conditions like high blood pressure or high cholesterol, whether it’s to reduce side effects or lower costs.
However, you may not need to switch from Mounjaro, but instead explore a lower dose. We’ll work with you to find the solution that’s right for your needs, budget and goals.
For those who need a more cost-effective option, Wegovy offers similar weight-loss results and some additional benefits, including support for heart health. If you choose to switch, our clinicians will make sure the change is safe, smooth, and tailored to you. That way, you can keep moving towards your health goals with minimal disruption.
Both Mounjaro and Wegovy are highly effective prescription treatments for weight management. Each works a little differently, but both have helped people achieve meaningful, long-term results when combined with healthy lifestyle changes.
In clinical studies, people taking Mounjaro (tirzepatide 15mg) lost an average of around 21% of their body weight over 72 weeks, while those using Wegovy (semaglutide 2.4mg) lost around 15% over 68 weeks.¹ ²
Both can be excellent options. The right choice comes down to your health needs, goals, lifestyle and how your body responds to treatment. Our medical team will help you find what works best for you.
¹ SURMOUNT-1, 72-week study of adults with obesity using Mounjaro (tirzepatide 15mg).
² STEP-1, 68-week study of adults with obesity using Wegovy (semaglutide 2.4mg). Individual results vary.
In some cases, we may recommend a lower starting dose to maximise comfort and minimise side effects during the switch. This isn't a step backwards — it's a clinically safe way to help your body adjust while keeping progress on track.
Our aim is always steady, sustainable weight loss without compromising tolerability.

Results that speak for themselves
Management of my appetite was the biggest challenge, so the medication [Wegovy] has really just been game-changing. I've been trying to lose weight for 14 years. As soon as I knew about this medication from my research, I ordered it the same night I found out it was available.
Chloe J. after 2 months
I had tried every diet under the sun. I finally plucked up the courage… and it has changed my life. I am happier, more confident, full of energy and able to run around after my children for longer. [It] has drastically improved my physical, emotional and mental health.
Rosie G. lost 25kg after 6 months
I was starting to get a pain in my knee which seems to have decreased a lot since losing the weight. I don't get any more back pain. It's made me a lot more confident within myself. I actually want to go out and do things. I want to go clothes shopping. I want to enjoy things with my kids.
Roisin S. lost 19.5kg after 3 months
I can do more. I feel more energetic. I can play more with my kids, whereas before I was restricted. It's mostly the breathlessness, the being slow, being out of breath, feeling heavy, not being able to put my clothes on properly because they were too tight. It's been a brilliant experience with MedExpress.
Magdalena S. lost 22kg after 4 months
I used to hide away in oversized clothes, just trying to feel comfortable—but I had no confidence. Now, I'm fitting back into clothes I haven't worn in years, and I actually enjoy getting dressed in the morning. I feel happier, more confident, and like I'm finally showing up as myself.
Natasha T. lost 29kg after 4 months
It's making me more happy about myself. I'm feeling more confident. I'm not hiding. If my friend invites me for a coffee, I won't say no anymore. I'm dressing-up! I'm taking care of myself now. I feel more happy every day. I'm more talkative. I'm going to more family events.
Premila C. lost 23kg after 4 months
The thing I like most is the aftercare. I get really helpful emails with tips and advice. After week one I’m 6lb down, so let’s see where it takes me on my weight loss journey.
Sonia, weight loss customer
Products are very effective. I’ve lost weight already in just 14 days so happy. Would recommend this company highly. In fact I’ve already introduced 3 people to MedExpress.
Shireen, weight loss customer
I am one week into treatment and feeling good — less cravings and fuller for longer in between meals. The website is really informative and ordering a straightforward process.
Mrs Roe, weight loss customer
I am having a good experience. No side effects presently. I love the feeling of not feeling hungry, it’s very calming for me. I am enjoying the journey so far.
Mr Gale, weight loss customer
Professional, quick to respond, quick delivery and the product has made me feel the most confident I have felt in years.
