Mounjaro is a prescription weight loss treatment in the UK. It is given as a weekly injection and is available in six doses: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg. The price can increase with the dose, so it is useful to compare the cost of the strength you have been prescribed.
This guide sets out the current price for each dose, explains what is worth comparing between providers and looks at clinical trial results by dose. This gives you a clearer idea of what the different strengths have shown in research, rather than relying only on a headline percentage.
Every order requires a clinical consultation with a UK registered prescriber before a prescription can be issued. Private Mounjaro prices can vary between providers and doses, so checking the full cost is important when comparing treatment options.
Key things to know
- Pricing is shown in three tiers: a regular price, a current price with a discount applied, and a Future Orders price for repeat orders
- Be cautious about claims that a pharmacy is the "lowest" or "best" priced provider in the UK, as prices and offers can change
- Everyone starts at 2.5mg, regardless of their eventual dose. The price can increase later if your prescribed dose is increased
- Clinical trial data is available for the 5mg, 10mg and 15mg maintenance doses, which can help you understand the average results reported at these strengths
- When comparing prices, look at the ongoing Future Orders price as well as the first order price, particularly if you expect to continue treatment
How Mounjaro Works and Why Dosing Is Gradual
Mounjaro is a weekly injection containing tirzepatide. It is a dual GIP and GLP 1 receptor agonist, which means it acts on two hormone pathways involved in appetite and blood sugar regulation.
Mounjaro is authorised in the UK for weight management in adults who meet the relevant BMI criteria, alongside a reduced calorie diet and increased physical activity. It is also used for certain adults with type 2 diabetes. NICE has issued guidance on the use of tirzepatide for weight management in certain circumstances.
Clinical trials have shown weight loss with tirzepatide, although the amount of weight lost varies from person to person. In the SURMOUNT 1 trial, the average weight loss reported at 72 weeks was higher at the 15mg dose than at the lower maintenance doses studied.
The six dose strengths allow treatment to be increased gradually. Everyone starts at 2.5mg, which is the licensed starting dose. The dose is usually increased in 2.5mg steps after at least 4 weeks on the current dose, if your prescriber considers an increase appropriate.
Starting at a higher dose is not recommended. Increasing the dose can also make side effects such as nausea and other digestive symptoms more likely or more noticeable. Your prescriber will decide whether to increase your dose based on your response to treatment and how well you tolerate it.
Eligibility and Safety Considerations
Mounjaro is not suitable for everyone, which is why a clinical assessment is needed before treatment is prescribed. Your prescriber will consider your medical history, current medicines and other relevant factors before deciding whether it is suitable for you.
Mounjaro should not be used during pregnancy. If you are planning to become pregnant or are breastfeeding, speak to your prescriber before using tirzepatide. It may also not be suitable for people with certain medical conditions or a history of certain health problems, so these should be discussed during your assessment.
Tell your prescriber if you have severe gastrointestinal problems, a history of pancreatitis, or other conditions that may affect your treatment. You should also mention any medicines you take, particularly medicines that lower blood sugar.
Common side effects can include nausea, reduced appetite, diarrhoea and constipation. These effects can be more noticeable when starting treatment or increasing the dose.
Seek urgent medical advice if you develop severe or persistent abdominal pain, as this can be a sign of pancreatitis. You should also seek urgent help if you develop signs of a serious allergic reaction.
If you take an oral contraceptive pill, tell your prescriber. They can advise you about whether additional contraception is recommended when starting or increasing tirzepatide.
Complete Price Comparison: All Six Doses
| Dose | Regular price | Current price | Future Orders price |
|---|---|---|---|
| 2.5mg | £174.99 | £144.99 | £149.99 |
| 5mg | £204.99 | £174.99 | £179.99 |
| 7.5mg | £254.99 | £224.99 | £229.99 |
| 10mg | £274.99 | £244.99 | £249.99 |
| 12.5mg | £304.99 | £274.99 | £279.99 |
| 15mg | £323.99 | £293.99 | £298.99 |
Private Mounjaro prices can vary across the UK depending on the provider, dose and any current offers. Some providers may advertise prices from around £120 per month, while other private prices can be higher, particularly for larger doses.
For a fair comparison, compare the same dose across providers. A lower starting dose may cost less than a higher dose, but your prescribed dose should be based on your clinical needs rather than price alone.
The regular price is the reference price before the current discount. The current price is the rate available for a first order. The Future Orders price is the price shown for repeat orders.
If you are planning to continue treatment, the Future Orders price can give you a more useful idea of your ongoing medicine costs than a first order offer.
Why "Lowest Price" and "Best Deal" Claims Are Hard to Verify
You may see pharmacies describe their Mounjaro service as the "lowest price" or a "best deal". These claims can be difficult to compare because prices, discounts and services can change.
A better approach is to look at the total cost over a realistic period. Check whether the price includes the clinical consultation, prescription, dispensing and delivery. Also check whether any additional charges apply.
Some UK providers include clinical and prescribing costs in one price, while others may list certain costs separately. Delivery charges, consultation fees and other services can therefore affect the final amount you pay.
First order discounts and Mounjaro discount codes can make an initial order cheaper. However, if you expect to continue treatment, the repeat order price is usually more useful when comparing providers.
Private Mounjaro prices can differ by more than £100 per month between providers, depending on the dose and services included. This is why it is useful to compare the complete service rather than choosing a provider based only on a "cheapest Mounjaro" claim.
Real Trial Data by Dose
The SURMOUNT 1 trial, published in the New England Journal of Medicine, studied tirzepatide at 5mg, 10mg and 15mg maintenance doses. After 72 weeks, the reported average weight loss was 15.0% with 5mg, 19.5% with 10mg and 20.9% with 15mg, compared with 3.1% with placebo.
These are average results from a clinical trial and do not predict exactly how much weight an individual will lose.
The results can still be useful when comparing doses. Higher doses produced greater average weight loss in the trial, although the difference between 10mg and 15mg was smaller than the difference between 5mg and 10mg.
The 12.5mg dose is used as a dose escalation step between 10mg and 15mg and was not one of the main maintenance doses reported in the SURMOUNT 1 results above.
Why Your Price Changes Over Time
Everyone starts treatment at 2.5mg, regardless of their eventual dose. Your prescriber will review how you are responding to treatment and whether you are tolerating it before deciding whether a dose increase is appropriate.
The dose is usually increased gradually rather than moving straight to a higher strength. This means your treatment cost may change during the first few months if your prescribed dose increases.
You should stay on your current dose unless your prescriber advises you to change it. Do not increase the dose yourself because a higher strength is available.
How to Compare Providers Fairly
- Check whether the quoted price is for a first order or an ongoing repeat order
- Compare the same dose across pharmacies rather than comparing different strengths or introductory offers
- Check that a genuine clinical consultation with an appropriately registered prescriber is included
- Verify GPhC registration independently using the regulator's public register rather than relying only on a badge displayed on a pharmacy website
- Use a GPhC registered pharmacy or another appropriately regulated UK service when buying Mounjaro online
- Calculate a realistic annual cost using the ongoing price rather than the first order price
- Check whether cold chain delivery is included and whether needles or other supplies are provided separately
- Do not assume that the cheapest Mounjaro provider is automatically the best option. Consider the clinical support, dispensing service, delivery arrangements and overall cost
- Be cautious about claims relating to supply, competitor pricing or guarantees about the authenticity of medicine if these claims cannot be independently checked
Estimating Annual Cost
| Dose | Future Orders price (per pen) | Approx. annual cost (13 pens) |
|---|---|---|
| 2.5mg | £149.99 | £1,949.87 |
| 15mg | £298.99 | £3,886.87 |
Mounjaro is taken once a week, and a KwikPen is designed to provide four weekly doses when used according to the instructions supplied with the medicine. This means that a full year of weekly treatment would require around 13 pens.
The figures above are estimates based on 13 pens at the stated Future Orders price. Your actual yearly cost may be different because your prescribed dose can change during treatment, and prices or offers may also change.
If your dose increases during the year, your total cost is likely to be different from simply multiplying the price of one strength by 13.
What's Included in the Price
The Mounjaro price includes your online clinical consultation with a UK registered prescriber, your prescription if you are clinically suitable for treatment, and dispensing through a GPhC registered pharmacy.
Some providers may also include clinical support and delivery within their advertised price, while others may charge separately. It is therefore worth checking exactly what is included before you order.
Standard approval typically takes around 3 working days. A paid express option may also be available for a faster review, depending on the current service.
Mounjaro requires appropriate temperature controlled handling. Check how the pharmacy manages cold chain delivery and whether any additional delivery or needle charges apply.
Bundle Options
Multi pen bundles may offer a saving compared with ordering individual pens, particularly once your dose has been established. However, the value depends on the current price of the bundle and the individual pens.
Current bundle prices are shown in the live pricing information at checkout. If you are comparing a bundle with individual pens, check the total cost and make sure the bundle matches the dose and treatment plan recommended by your prescriber.
Getting Started with EverydayMeds
Treatment begins with a free online clinical consultation reviewed by our UK registered prescribing team. Mounjaro is a prescription only medicine, so it should only be supplied after an appropriate clinical assessment.
Your consultation covers relevant information such as your medical history, current medicines and weight related health. Your prescriber will then decide whether Mounjaro is suitable and, if so, whether the treatment can be prescribed.
Mounjaro is supplied through our GPhC registered pharmacy. You should always check that an online pharmacy is properly registered before ordering prescription medicines online.
NHS access to Mounjaro for weight management is subject to eligibility criteria and the NHS rollout arrangements. Private treatment is separate from NHS prescribing and is paid for by the patient.
The consultation is an important part of the process because it allows a healthcare professional to assess whether the medicine is appropriate for you rather than treating the purchase as a simple online transaction.
