Mounjaro Price Guide
At The Family Chemist, Mounjaro costs between £164.99 and £293.99 a month. The price depends on your dose and varies across the UK, largely because the manufacturer raised its prices in September 2025.
Key Takeaways
- At The Family Chemist, Mounjaro costs £164.99–£293.99 a month, depending on your dose and whether you need a starter pack.
- Prices rose across the UK market after Eli Lilly raised its list price by up to 170% on 1 September 2025.
- Your price covers everything: a clinical assessment with a UK-registered prescriber, dispensing by our GPhC-registered pharmacy, and genuine UK-sourced medication.
- Treatment starts low, at 2.5 mg, and builds up gradually. Higher doses cost more because each pen holds more medicine and is more expensive to buy.
- There’s no cheaper generic yet – Mounjaro is still under patent in the UK.
- NHS access is rolling out slowly and in stages, so many people don’t qualify yet. Paying privately is a regulated way to start without waiting.

Why did Mounjaro prices change in 2025?
Mounjaro costs noticeably more than it did a year ago, and there’s one reason behind it. In August 2025, Eli Lilly told providers it would raise its UK list price – the wholesale price pharmacies pay increased by as much as 170% from 1 September.
Eli Lilly reasoned that Mounjaro had originally launched in the UK at a price below the European average, and that it was bringing prices in line with other countries. Every pharmacy in the UK buys medication at the higher price, so prices have increased across the market.
Some pharmacies absorbed part of the rise; others passed it on in full. That’s why you’ll see such a wide range of prices. NHS pricing sits under a separate agreement and wasn’t affected in the same way.
How our pricing compares
Our prices are towards the lower-to-middle end. If you’re comparing pharmacies, it’s worth checking what each price includes. A cheaper headline figure can be more expensive in the end once a separate consultation fee, delivery, or continued support is added on top.
With us, all of that is part of the price. To weigh up your options properly, our guide to comparing weight-loss pharmacies in the UK sets out what to look for.
What is included in the price?
Your price isn’t just for the pen. Every order includes a clinical assessment with a UK-registered prescriber and, where it’s appropriate, a private prescription. We dispense from our own GPhC-registered pharmacy using genuine UK-sourced stock from licensed wholesalers.
- Tracked delivery, in temperature-controlled packaging
- Complimentary access to Nutrable app – nutritional coaching, meal plans and recipes, advice on food, lifestyle habits and more
- Direct access to prescribers via email whenever you need ongoing support, at no extra cost
You won’t be signed up to a subscription, and treatment only goes ahead once a prescriber has approved it.
Why does the price of Mounjaro vary by dose?
The price goes up as the dose goes up, for two simple reasons. Each pen is made at a set strength, and stronger pens contain more of the active ingredient, tirzepatide. Additionally, higher-dose pens cost pharmacies more to purchase from the manufacturer, so the supply cost increases with higher dose strength.
The gap between doses really comes down to how much medicine is in the pen and what it costs to supply—cold-chain handling, UK wholesale costs and regulated dispensing all feed into the retail price as well.
Not everyone ends up on the highest dose, either. Plenty of people do well on the middle strengths. Our clinicians will decide which suits you based on how you respond and what you can tolerate.
Still under patent — no generic available
Mounjaro (tirzepatide) is still under patent in the UK, which means no company can legally make or sell a cheaper generic version of tirzepatide yet. Until then, pharmacies must source the branded product. Prices often fall once a medicine is no longer under patent and a generic version is approved.
- Can you get Mounjaro on the NHS?
Yes, but access is limited. Mounjaro became available on NHS prescription in primary care from 23 June 2025.
However, the NHS is introducing it in phases over several years, and whether you can get it depends on your local Integrated Care Board (ICB) and whether specialist weight-management services are operating near you.
Pharmacy-based weight-management pilot trials are expected to begin during 2026. For now, a lot of people aren’t eligible yet.
If you do qualify and services are available locally, the NHS route is cheaper than private care. In England you’ll pay the standard prescription charge of £9.90 per item unless you’re exempt; prescriptions are free in Scotland, Wales and Northern Ireland.
Who is eligible on the NHS first?
The current criteria for getting treatment on the NHS is:
a BMI of 40 kg/m² or above (adjusted for ethnicity where appropriate)
at least four obesity-linked conditions:
- hypertension
- dyslipidaemia
- obstructive sleep apnoea
- cardiovascular disease type 2 diabetes.
Early on, prescribing often happens through specialist weight-management services rather than a standard GP appointment, and access should widen as the rollout expands. Your GP or local ICB can tell you about the current criteria in your area.
Private access through The Family Chemist
With the NHS rollout moving slowly and the thresholds set high, many people don’t currently qualify – or face a wait before local services open up.
If it’s clinically right for you, private treatment is a suitable way to get started.
Private treatment process
- Complete a structured medical assessment,
- One of our clinicians reviews it
- Issue a private prescription if you’re suitable
- Dispensed from our pharmacy.
Already taking Mounjaro elsewhere?
Our prescribers can review your history and assess whether to continue at your current dose.
Whether you’re new or transferring, it’s worth letting your NHS GP know about any private medication so your care stays joined up.
Consultation and eligibility
Mounjaro is suitable for adults who meet certain clinical criteria and can use it safely with medical supervision.
You may be eligible if your BMI is 30 or above between 27 and 30 alongside a weight-related condition such as;
- hypertension,
- dyslipidaemia,
- pre-diabetes
- or cardiovascular disease.
For patients from ethnic backgrounds, you can be eligible with a BMI of 27.5 because health risks can appear at a lower BMI.
Everyone completes a medical consultation first to ensure that Mounjaro is clinically appropriate and safe for you before a prescription is issued.
Safety and regulation
Mounjaro (tirzepatide) is a prescription-only medicine (POM) in the UK, so it can’t be supplied without a prescription.
A few things to be aware of
Tirzepatide shouldn’t be used during pregnancy or while breastfeeding, and it may not suit certain conditions. Because it can slow stomach emptying, we might advise you to use extra contraception alongside the pill, and if you’re on HRT, we might suggest a patch instead of tablets.
Tell your healthcare provider you’re taking it if you’re due to have surgery.
Side effects can happen with any medicine; with Mounjaro, nausea and other stomach upsets are common, usually when you’re moving up a dose. You can report any suspected reaction through the MHRA Yellow Card Scheme.
When you’re choosing where to go, put regulation, clinical oversight and honest pricing first.

If you would like to see current availability and confirm your eligibility, you can begin a secure online consultation at any time.
How much does Mounjaro cost per month?

How much is the 2.5 mg and 5 mg dose?
The 2.5 mg pen is £164.99, or £178.99 as a starter pack with needles, swabs and a sharps bin. The 5 mg dose is £234.99 for four weeks.
Why did Mounjaro get more expensive in 2025?
Eli Lilly raised its UK list price by up to 170% from 1 September 2025, to bring UK pricing in line with other countries. Because pharmacies now pay more for medication, private prices have gone up across the board. The NHS price was handled separately.
Can I transfer my Mounjaro prescription from another provider?
Yes. If you’re already on Mounjaro, our prescribers will review your treatment history from your previous provider and assess whether to continue at your current dose. You’ll still need to complete a medical assessment so we can prescribe safely.
Is Mounjaro cheaper on the NHS?
If you qualify and services are running in your area, yes, it is cheaper (£9.90 per item in England, free elsewhere in the UK). The catch is that NHS access is limited and phased, so many people don’t qualify yet. If that’s you, private treatment is an alternative without the wait. Talk to your GP about this, or complete our online assessment.
Does the price include the consultation, and what happens after I order?
The consultation is included in the price. If Mounjaro is right for you, we issue a private prescription, dispense it from our GPhC-registered pharmacy, and send it out via tracked delivery in temperature-controlled packaging.
Why does the dose affect the price?
Higher strengths contain more tirzepatide and cost pharmacies more to buy, and there’s no generic version yet because Mounjaro is still under patent. The price reflects the manufacturer’s supply cost, cold-chain handling and proper dispensing. Your prescriber suggests the dose based on your clinical needs.
