If you are a UK adult comparing private prescription weight management costs or trying to understand the difference between private treatment and NHS access, this page gives you the 2026 price information by dose first. It also explains why prices changed after 2024, what may affect the amount you pay, how to compare pharmacy prices, which extra costs may apply, how payment plans work and why overseas prices are not always useful for UK patients.
Mounjaro is a prescription only medicine containing tirzepatide. It can only be supplied following an appropriate clinical assessment, and a prescriber may decide that treatment is not suitable.
Key things to know
- One KwikPen holds four weekly doses, so one pen generally covers about four weeks
- Treatment normally starts at the lowest strength, although the exact treatment plan is decided by the prescriber
- The figures in this guide refer to standard prices rather than promotional or first order offers
- Prices published in 2024 and early 2025 may no longer reflect current private prices
- The live price shown by the provider when you order should always take precedence over an older published figure
Mounjaro Price List UK: Every Dose
The table below shows the standard price per pen at each strength, what that works out at per weekly injection, and what 13 pens would cost across a year if someone stayed on the same strength throughout that period.
The 10mg Mounjaro price UK 2026 patients may see at standard rates is around £244.99 per pen. Across the full range, private prices can be around £120 to £340 for a four week supply, depending on the strength and provider.
The annual figure should be treated as a simple calculation rather than a prediction of what your treatment will cost. Many people do not remain on the same strength for a full year, and your prescriber decides whether a dose change is appropriate.
Prices also vary between providers. The lowest strength may be available from around £120 per month, while higher strengths can cost considerably more. For example, a 5mg pen may be around £174.99 and a 15mg pen around £293.99 at the prices used for this guide.
When comparing prices, do not look only at the starter pen. Your treatment plan may change over time, and the price can increase if your prescribed strength changes.
Why 2026 Prices Look So Different From 2024
Older Mounjaro prices can look very different from the figures available today. One reason is the change to UK pricing announced by Eli Lilly in 2025.
On 14 August 2025, Eli Lilly announced that the UK list price of Mounjaro would increase from 1 September 2025, with increases of up to around 170 per cent at the highest strengths. The highest strength increased from roughly £144.99 to around £293.99 per pen at list price. The NHS price was not affected by that announcement.
Because Eli Lilly is the manufacturer of Mounjaro, changes to its list pricing can affect the wider private market. However, the final price paid by a patient can still vary between providers because pharmacies may have different fees, margins, discounts and service costs.
This is why older guides can show figures that no longer match current prices. If you find a Mounjaro price list UK or a mounjaro price uk 2025 guide, check when it was published and whether the figures have been updated since 1 September 2025.
Private retail prices can also change over time. Future changes are difficult to predict, so it is better to check the current price before ordering rather than relying on an older estimate.
Will the Price of Mounjaro Go Down in 2026?
Two common questions are whether the private price of Mounjaro will go down in 2026 UK and whether the price will go down for NHS patients. These are different questions because private and NHS access work differently.
The private answer
There is no reliable way to predict whether private Mounjaro prices will fall during 2026. The manufacturer price, pharmacy costs, competition, discounts and demand can all affect the final amount you pay.
Price comparison services and greater transparency can make it easier to compare providers. Some pharmacies may also offer introductory discounts or other promotions. However, a lower first order price does not necessarily mean a lower cost over several months.
When comparing providers, look at the standard price for the strength you are likely to use and include any consultation, prescription, delivery, needle or follow up fees.
The NHS answer
Wider NHS access changes how eligible patients pay for treatment rather than setting a separate retail price.
If you qualify for NHS treatment, what you pay depends on the UK nation where you receive treatment and the relevant prescription rules. NHS eligibility criteria also differ from private prescribing criteria.
This means the Mounjaro prescription cost UK patients face depends largely on whether they are using a private or NHS route and whether they meet the relevant eligibility requirements.
Mounjaro NHS Price Compared With Private
There is no publicly available Mounjaro NHS price in the same way that private pharmacies publish retail prices. The price paid by the NHS is based on its purchasing and contractual arrangements.
For patients, prescription charges depend on where they live. In England, eligible patients normally pay the standard prescription charge per item unless they are exempt or have another form of support. Prescriptions are free in Scotland, Wales and Northern Ireland under their respective NHS arrangements.
The main point is eligibility. NHS access to tirzepatide for weight management is subject to clinical criteria and is being introduced in phases. Private prescribing follows a separate route and also requires a clinical assessment.
Mounjaro Price Across UK Pharmacies
Queries such as mounjaro price across uk pharmacies uk, mounjaro price across uk pharmacies cost, mounjaro price comparison uk 2026, uk mounjaro private pharmacy prices 2026, uk mounjaro private provider prices 2026, uk mounjaro private price 2026, uk private mounjaro monthly cost 2026, mounjaro uk price private prescription 2026 and mounjaro uk pharmacy prices 2026 are usually looking for the cheapest provider.
Private Mounjaro prices can commonly fall around £140 to £260 or more per month, depending on the strength, provider and services included. Prices change regularly, so comparing the full cost is more useful than relying on one advertised figure.
When comparing providers:
- Compare the same dose rather than comparing one provider's starter pen with another provider's higher strength.
- Compare standard prices on both sides. An introductory discount usually applies only to an initial order.
- Add consultation fees, which may add around £10 to £30 to the first month, delivery charges of around £3 to £8, separate needle charges of about £5 to £10 per month at some pharmacies, and the cost of a sharps bin.
- Check the full range of doses rather than only the entry price. A low starter price may not represent the cost of treatment if your prescribed strength changes.
- Multiply the monthly figure by 13 if you want to estimate the cost of 13 pens rather than simply multiplying by 12 months.
Looking at the full cost can give you a more realistic comparison between providers. The medicine itself is the same licensed product, while the total amount you pay can vary because of pharmacy pricing, consultations, delivery and additional services.
Searches for the cheapest Mounjaro or the cheapest Mounjaro UK offers often focus on the first order price. That figure can be useful, but it does not tell you what ongoing treatment may cost.
Mounjaro price in London and regional pricing
There is no separate London price for Mounjaro. Private providers set their own prices, so the same provider will generally charge the same price for a particular strength regardless of whether you live in London, Leeds or Llandudno.
An in person clinic may cost more overall because it can include consultations, follow up appointments or other services. This does not necessarily mean that the medicine itself has a different regional price.
What the Advertised Price Does Not Include
The price shown for a Mounjaro pen may not always include every cost involved in treatment. Check the full price before ordering so you know what you are paying for.
- Pen needles. The KwikPen is supplied without needles, and a fresh needle is used for each injection. Some pharmacies charge separately for needles at around £5 to £10 per month.
- A sharps bin for safe disposal of used needles.
- Consultation fees, which may add around £10 to £30 to the first month.
- Delivery charges, which may range from around £3 to £8 depending on the provider and delivery service.
- The cost of future pens. A starter pen may cost less than a higher strength pen, so your monthly cost can change if your prescribed dose changes.
You can check the current figures directly against the full range of Mounjaro injection strengths and pricing rather than relying on an older published price range.
Mounjaro Payment Plan UK
Some providers offer interest free instalments at checkout. Availability can change, so check the payment options shown when you order rather than relying on an older website page or footer logo.
From 15 July 2026, certain interest free instalment credit arrangements are subject to Financial Conduct Authority regulation. The protections that apply can depend on the type of credit agreement you enter into.
If you use a payment plan, the credit agreement is with the lender rather than the pharmacy. Instalments change when you pay, but they do not reduce the overall cost of treatment.
Because Mounjaro prices can increase when the prescribed strength increases, make sure you understand how much you will repay and when payments are due before agreeing to a plan.
If you are worried about the cost of treatment or managing repayments, free and impartial support is available from organisations such as StepChange, National Debtline and Citizens Advice. This information is not financial advice.
Prices in Other Countries
Comparisons with overseas markets are common, including searches such as mounjaro 15mg price malaysia. However, an overseas price does not necessarily tell you what a UK patient can pay or legally access.
Prices can differ between countries because of local regulations, supply arrangements, taxes, pharmacy fees and healthcare systems. A price advertised on an overseas website may also not include delivery, medical assessment or other costs.
If you live in the UK, do not assume that you can legally order prescription medicines from another country and have them sent to you. Check the current rules before attempting to import any prescription medicine.
If you want to buy Mounjaro online in the UK, use a pharmacy that is appropriately registered with the General Pharmaceutical Council and follow the required prescribing process. The MHRA also advises patients to be cautious about buying medicines from unregulated sellers.
Buying from an unregulated source carries risks because you may not know whether the medicine is genuine, has been stored correctly or contains the stated ingredient. Mounjaro also needs appropriate temperature controlled storage, so storage during delivery is another important consideration.
