How Much Does Mounjaro Cost in the UK?
Mounjaro (tirzepatide) costs between £130 and £340 per pen in the UK private market in 2026, depending on the dose strength and pharmacy provider. The starter dose of 2.5 mg begins at approximately £130 per pen from some GPhC registered pharmacies, while the highest maintenance dose of 15 mg reaches up to £340 across the market.
Because treatment follows a titration schedule, meaning the dose usually increases every four weeks, most people will see their monthly costs rise progressively throughout their first several months. That is why the headline starter price is useful, but it should not be treated as the full cost expectation for an ongoing course.
This article is a fully independent Mounjaro price UK guide. No pharmacy or provider is being promoted, and nothing here constitutes medical advice. All treatments mentioned are prescription only medicines.
What Is Mounjaro and Why Does Dose Affect Price So Much?
Mounjaro is the brand name for tirzepatide, a medication that acts on two separate receptors in the body: GIP, which stands for glucose dependent insulinotropic polypeptide, and GLP 1, which stands for glucagon like peptide 1. This dual action mechanism is what distinguishes it from older single receptor treatments. Clinical data from the SURMOUNT trial programme has positioned it as one of the most effective pharmaceutical weight management options currently available.
If you want the mechanism before you compare pharmacy prices, the independent Mounjaro tirzepatide weight loss guide explains how appetite, blood sugar and dose progression fit together in plain English.
The reason dose affects price so significantly is straightforward: each pen contains a higher concentration of active ingredient at higher doses. Manufacturers price accordingly, and pharmacies usually follow the same stepped pricing structure across all available strengths.
Mounjaro Price by Dose: Full UK Breakdown 2026
The table below reflects approximate pricing across GPhC registered UK pharmacies as of 2026. Prices vary between providers and are subject to change, so always confirm with the pharmacy directly before placing an order.
| Dose Strength | Injection Frequency | Approximate Price Per Pen | Estimated Monthly Cost |
|---|---|---|---|
| 2.5 mg | Weekly | £130 to £180 | £130 to £180 |
| 5 mg | Weekly | £155 to £200 | £155 to £200 |
| 7.5 mg | Weekly | £200 to £270 | £200 to £270 |
| 10 mg | Weekly | £220 to £305 | £220 to £305 |
| 12.5 mg | Weekly | £245 to £315 | £245 to £315 |
| 15 mg | Weekly | £260 to £340 | £260 to £340 |
Each pen delivers four weekly doses, making the per pen cost equivalent to the monthly medication cost at most standard dose steps.

How Mounjaro Titration Works and What It Means for Your Budget
Understanding the Mounjaro titration schedule is essential for accurate cost planning. Most clinical guidance follows a structure similar to this:
- Weeks 1 to 4: 2.5 mg starter dose
- Weeks 5 to 8: 5 mg
- Weeks 9 to 12: 7.5 mg, although some patients may maintain here
- Weeks 13 to 16: 10 mg
- Weeks 17 to 20: 12.5 mg
- Week 21 and beyond: 15 mg, which is the maximum licensed dose if tolerated and required
Not every person will progress to the highest dose. Some individuals respond well at 5 mg or 7.5 mg and may remain there long term, which has a significant impact on total costs. However, titration speed and the dose at which someone stabilises is a clinical decision, not one driven by price.
Therefore, when planning for Mounjaro costs, it is more useful to estimate for the dose range most likely for you rather than to anchor on the starter price. A practical approach is to compare both your current pen cost and the possible maintenance dose cost before beginning treatment.
Total Mounjaro Cost: First Year vs Ongoing
Estimated Year One Cost
During year one, most patients spend several months on lower starter doses before reaching their maintenance dose. A rough year one projection, assuming gradual titration, looks like this:
| Scenario | Approximate Year 1 Cost |
|---|---|
| Stabilise at 5 mg | £1,860 to £2,400 |
| Stabilise at 7.5 mg | £2,200 to £2,900 |
| Stabilise at 10 mg | £2,600 to £3,400 |
| Stabilise at 15 mg full course | £2,900 to £4,000 |
Estimated Ongoing Annual Cost at Maintenance
| Maintenance Dose | Estimated Annual Cost |
|---|---|
| 5 mg | £1,860 to £2,400 |
| 7.5 mg | £2,400 to £3,240 |
| 10 mg | £2,640 to £3,660 |
| 12.5 mg | £2,940 to £3,780 |
| 15 mg | £3,120 to £4,080 |
These are estimates only and do not include any consultation, delivery, or programme fees that may apply. For a more realistic budget, add the recurring non medication costs to the pen price rather than treating them as separate one off extras.
What Else Affects the Total Cost of Mounjaro?
The pen price is the largest component of your monthly spend, but it is not always the only one. Before committing to a provider, check whether any of the following apply:
Consultation fees. Some providers charge separately for the initial clinical assessment and for ongoing prescription renewals. This can range from £20 to £50 per episode, charged outside the medication cost.
Delivery charges. Mounjaro requires cold chain delivery due to refrigeration requirements. Delivery fees vary widely, from zero to around £15 per order, and on a monthly ordering cycle this adds up meaningfully.
Programme or monitoring fees. Certain providers include structured coaching or clinical check ins as part of their service, priced as a subscription layer on top of the medication cost.
Subscription vs single order pricing. Some pharmacies offer a lower per pen price for patients who commit to a monthly subscription plan rather than ordering individual pens.

How Does Mounjaro Compare in Price to Wegovy and Saxenda?
At the starter dose, Mounjaro and Wegovy are priced within a broadly similar range. However, the comparison shifts at higher doses:
| Treatment | Starter Dose Price | Maintenance Dose Price |
|---|---|---|
| Mounjaro (tirzepatide) | £130 to £180 | £260 to £340 |
| Wegovy (semaglutide) | £130 to £170 | £240 to £295 |
| Saxenda (liraglutide) | £150 to £290 per month | £200 to £290 per month |
Mounjaro tends to be the most expensive at higher dose levels. Whether that cost difference represents good value depends on how each person responds to treatment, which is a clinical variable rather than a pricing one.

Is Mounjaro Available on the NHS?
Mounjaro received NICE approval for use in weight management in the UK and is currently being introduced into NHS commissioning through a phased rollout. However, NHS access remains limited by local clinical commissioning criteria and capacity, and the majority of UK patients still access tirzepatide through private prescriptions in 2026.
If NHS eligibility is relevant to your situation, your GP or a specialist weight management service is the right point of contact. This article covers only private market pricing.
How to Verify a Pharmacy Before Buying Mounjaro
Because Mounjaro is a prescription only medicine, it must only be supplied following a proper clinical assessment. Before ordering from any pharmacy, verify the following:
- GPhC registration: check the pharmacy registration number on the official GPhC pharmacy register.
- Prescriber credentials: the prescribing clinician should be named and GMC registered.
- MHRA internet pharmacy logo: it should be displayed and clickable on the pharmacy homepage.
- Full fee disclosure: all costs, including medication, consultation, delivery and monitoring, should be visible before checkout.
For a structured way to evaluate online pharmacy credentials alongside pricing, the UK online pharmacy verification and GPhC safety standards guide gives useful independent context before you compare providers.
