Quick Answer
Understanding Why People Look for a Mounjaro Alternative
Mounjaro (tirzepatide) has attracted significant attention since its approval for weight management in the UK. It works on two receptors, GIP and GLP-1, making it a dual-action treatment that many patients find highly effective. However, there are several reasons someone might need or want an alternative:
- Mounjaro is unavailable or out of stock at their pharmacy
- They have experienced side effects that have not settled
- Cost or access through a private prescription has become a barrier
- A clinician has recommended a different approach based on their health profile
- They are needle-averse and interested in a tablet option
Whatever the reason, understanding what is actually available, and what each option does, is a sensible starting point.

Wegovy: The Most Comparable Alternative
Wegovy (semaglutide 2.4mg) is the most clinically similar alternative to Mounjaro for weight management. It is a GLP-1 receptor agonist, meaning it mimics a hormone released after eating that helps regulate appetite, slow gastric emptying, and promote a feeling of fullness. Crucially, unlike Ozempic, Wegovy is specifically licensed for weight loss in the UK.
Clinical trials have shown that patients using Wegovy alongside lifestyle changes can achieve meaningful and sustained weight loss. It is administered as a weekly subcutaneous injection, with the dose gradually increased over several months to reduce side effects.
Key points about Wegovy:
- Licensed in the UK specifically for weight management
- Weekly injection, self-administered
- Dose titrated gradually over 16 to 20 weeks
- Most common side effects are gastrointestinal, particularly in the early stages
- Not suitable for those with a personal or family history of medullary thyroid carcinoma or MEN2
What About Ozempic?
Ozempic contains the same active ingredient as Wegovy (semaglutide), but at a lower dose (up to 2mg) and with a different licence. Ozempic is approved for the management of type 2 diabetes, not for weight loss. This is an important distinction.
While Ozempic is often discussed in the same breath as Mounjaro and Wegovy in popular media, it is not something we are able to prescribe for weight loss purposes at our clinic. Prescribing it off-licence for weight management would not be appropriate in a standard private pharmacy setting, and patients who are not diabetic should not be accessing it through channels that bypass proper clinical oversight.
If you have type 2 diabetes and are also managing your weight, Ozempic may be relevant, but that conversation needs to happen with your GP or specialist, not through a weight loss pathway.
Orlistat: The Tablet Option
Orlistat works in an entirely different way to GLP-1 receptor agonists. Rather than acting on appetite hormones, it reduces the absorption of dietary fat in the gut by approximately one third. It is available as a prescription-only tablet (Xenical 120mg) and is taken with meals up to three times daily.
The results with Orlistat are typically more modest than those achieved with injectable GLP-1 medications. It tends to suit patients who are making significant dietary changes and want support with fat absorption, but who are not candidates for or are not comfortable with injections.
It is also worth noting that the side effects of Orlistat are closely tied to fat intake. If a patient continues to eat a high-fat diet, they may experience oily stools, urgency, and gastrointestinal discomfort. Adhering to a lower-fat diet while using Orlistat significantly reduces these effects.
The Wegovy Pill: A New Development Worth Knowing About
For those who are interested in the benefits of semaglutide but prefer to avoid injections, there is genuinely encouraging news. In 2025, the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) approved the first oral GLP-1 tablet for weight loss in the UK, an oral version of semaglutide developed by Novo Nordisk.
This is a significant milestone. Until this approval, all GLP-1 medications for weight loss required injection. The oral formulation offers the same active ingredient as Wegovy, making it a genuine injection-free alternative for eligible patients. Availability is still rolling out, and as with all new treatments, suitability will depend on individual health factors. If this is of interest to you, our team is happy to discuss whether it might be appropriate.

How to Choose the Right Option
Choosing between these treatments is not something that should happen based on a blog post alone. A thorough clinical assessment, covering your weight history, health conditions, current medications, and lifestyle, is essential before starting any weight loss treatment. That said, here are some general pointers that may help frame the conversation:
- Wegovy is currently the most comparable alternative to Mounjaro and is properly licensed for weight management in the UK
- Ozempic is not an appropriate route for weight loss unless you have type 2 diabetes and it is prescribed for that condition
- Orlistat suits those who prefer a tablet, are making meaningful dietary changes, and have more modest weight loss goals
- The Wegovy pill is worth exploring if you are eligible and strongly prefer to avoid injections

Frequently Asked Questions
Can I switch from Mounjaro to Wegovy directly?
It is possible to transition between GLP-1 treatments, but this should always be done under clinical guidance. There is no standard universal protocol, and the timing of any switch, along with the starting dose of the new medication, will depend on where you are in your current treatment, your side effect history, and your overall health picture. Please do not attempt to switch without speaking to a healthcare professional first.
Why can’t I get Ozempic for weight loss if it contains the same ingredient as Wegovy?
This is a very common question. Ozempic and Wegovy both contain semaglutide, but they are licensed for different purposes and at different doses. Ozempic (maximum 2mg) is licensed for type 2 diabetes. Wegovy (2.4mg) is licensed for chronic weight management. Prescribing Ozempic off-licence to non-diabetic patients for weight loss is not considered appropriate practice in a standard private setting, and in recent years the NHS has also raised concerns about Ozempic being diverted from diabetic patients for cosmetic weight loss purposes. Wegovy is the correctly licensed route for non-diabetic weight management.
How does the new Wegovy pill compare to the injection?
The oral semaglutide tablet uses the same active ingredient as the Wegovy injection, but the delivery mechanism and absorption route are different. Because oral absorption of semaglutide is limited, the tablet uses a higher milligram dose than the injection alongside a specific absorption enhancer called SNAC, to achieve effective blood levels. Clinical trials suggest it is effective for weight loss, though data comparing it head-to-head with the injection is still emerging. For those who have a strong aversion to needles, it represents a genuinely new option. Availability is still expanding across the UK, so do ask our team about current access.
Is Orlistat worth trying if GLP-1 treatments are not suitable for me?
Orlistat can be a reasonable option in the right context. It works differently to GLP-1 medications and will not suppress appetite in the same way, but it can reduce the amount of dietary fat your body absorbs. Its effectiveness is closely tied to dietary adherence. If you continue eating a high-fat diet, the side effects can be unpleasant. However, if you are genuinely committed to reducing fat intake and need additional support, it can add value as part of a broader plan. It is also the longest-standing pharmaceutical weight loss treatment available in the UK, so there is a well-established safety profile.
What should I expect at a weight loss consultation in Chelsea?
At our Chelsea clinic, a weight loss consultation involves a full review of your health history, current medications, BMI, any underlying conditions, and your personal goals. We will discuss which treatments are appropriate for you specifically, explain the expected results, side effect profile, and titration schedule, and answer any questions you have. We do not operate a one-size-fits-all approach. If medication is not the right starting point for you, we will tell you honestly and help direct you appropriately. Our clinic is at 6 Elystan Street, Chelsea, London, SW3 3NS.
Are there any people who should not take GLP-1 weight loss medications?
Yes. GLP-1 treatments including Wegovy and Mounjaro are not suitable for everyone. They are generally not recommended for:
- People with a personal or family history of medullary thyroid carcinoma (MTC)
- Those with Multiple Endocrine Neoplasia syndrome type 2 (MEN2)
- People with a history of pancreatitis
- Pregnant or breastfeeding women
- Those with severe gastrointestinal conditions affecting motility
- Individuals with certain kidney or liver conditions, depending on severity
A thorough clinical assessment before starting treatment is essential to ensure safety. This is why a proper consultation matters.
