How Much Is Mounjaro – UK Price per Dose & Best Deals (2025)
For anyone considering Mounjaro (tirzepatide) for weight loss in the UK, the first question is usually about cost. Prices vary widely depending on the dose, the pharmacy, and when you buy. As of 2025, the monthly price for a single pen can range from around £120 to over £370. This guide breaks down those costs by dose and by the major UK pharmacies, explains why prices have changed, and points to the cheapest options available.
The most useful way to compare prices is by the cost per month. In the UK, Mounjaro is typically supplied as one pre-filled pen containing four doses, which lasts for four weeks. This means the price you see is usually the price for a full month of treatment.

Mounjaro 2.5mg / 5mg / 7.5mg / 10mg Price: Full Dose Breakdown
The price you pay depends on the dose strength you are prescribed. The 2.5mg dose is the introductory level, while higher doses like 10mg, 12.5mg, and 15mg are used for maintenance and typically cost more. Based on available comparison data, the cheapest provider across all doses is Pills2U, according to the discount Mounjaro price list.
Cheapest Price for Each Dose
- 2.5mg: £123.99 (Pills2U)
- 5mg: £142.99 (Pills2U)
- 7.5mg: £196.98 (Pills2U)

It is also worth looking at a Mounjaro price comparison to see how different retailers stack up against each other. The 15mg dose, while the most expensive in absolute terms, often offers the best value when calculated per milligram of the active ingredient.
The Pharmaceutical Journal reported that from 1 September 2025, Lilly’s UK private list prices rose to £133 for 2.5mg and up to £330 for 12.5mg and 15mg pens. These are manufacturer-level list prices paid by pharmacies, not necessarily the final price paid by patients.
Which UK Pharmacy Has the Cheapest Mounjaro? (Boots, Superdrug, Asda, Pharmacy2U)
Prices from the major high-street and online pharmacies show significant variation. Based on the available data, Asda Online Doctor is the cheapest among the four well-known providers for most doses. The table below shows the public prices for each provider.
| Provider | 2.5mg | 5mg | 7.5mg | 10mg | 12.5mg | 15mg |
|---|---|---|---|---|---|---|
| Boots | £176.97 | £189.97 | £267.97 | £302.97 | £314.97 | £334.97 |
| Asda | £148.97 | £192.47 | £252.47 | £282.47 | £292.47 | £302.47 |
| Pharmacy2U | £189.99 | £214.99 | £264.99 | £294.99 | £309.99 | £324.99 |
| Superdrug | £195.00 | £245.00 | £295.00 | £335.00 | £345.00 | £370.00 |
Asda is cheaper than Boots, Superdrug, and Pharmacy2U for the 2.5mg, 7.5mg, 10mg, 12.5mg, and 15mg doses. Boots is cheaper than Superdrug and Pharmacy2U for the 2.5mg and 5mg doses. Pharmacy2U stated it would freeze its Mounjaro prices after the September 2025 manufacturer price rise, which may make it more competitive for some doses than the others, though its public prices still sit above those found on comparison sites.
The biggest savings come from using independent pharmacy comparison lists rather than going directly to a high-street brand. The difference between the cheapest online option and the most expensive brand-name pharmacy can be over £100 per month for the same dose.
Why Have Mounjaro Prices Risen So Much in 2025?
The primary reason for the price increase is a change in the manufacturer’s list price. Eli Lilly, the company that makes Mounjaro, increased its prices across all strength levels from 1 September 2025. Boots Online Doctor confirmed this price increase and noted that price variation across legitimate UK providers is expected. This has pushed the cost of pens upward by roughly £20 to £60, depending on the dose and the pharmacy.
Whether prices will continue to rise or stabilise in 2026 is not officially confirmed. Similarly, it remains unclear if or when the NHS will cover Mounjaro for more indications, which could affect private pricing. The exact cheapest price also changes frequently, as no single pharmacy holds the lowest price permanently.

Understanding the UK Mounjaro Market
UK Mounjaro prices can appear higher than in some other markets, partly due to the private healthcare model which includes consultation fees. Most online pharmacies operate an online consultation service that must be completed before purchase, and the cost of this assessment is sometimes included in the advertised pen price.
The economics of titration also play a role. Starting doses like 2.5mg seem cheaper, but patients are typically moved up through the dose ladder over several months. This means the total cost of a full treatment course can be substantial. Supply chain factors, including stock shortages, can also temporarily spike prices at certain pharmacies.
