What does Mounjaro cost once you reach a maintenance dose?

Step 1: how UK private Mounjaro pricing is actually structured

Mounjaro is dispensed as a pre-filled KwikPen covering four weekly doses. The price you pay is set per pen, and the pen's strength determines the price. Starting at 2.5mg and titrating upward through 5mg, 7.5mg, 10mg, 12.5mg and 15mg means that by the time most people reach a maintenance dose (the highest dose they tolerate well and continue on long-term) they are often paying noticeably more per month than they did in week one. Following Eli Lilly's price increase in September 2025, reported private market prices range from around £149 at lower doses to around £375 at the highest, depending on the provider, and if you want to understand how much one dose of Mounjaro works out to at each stage, that figure shifts considerably as you titrate up. These figures are widely reported market observations, not a price guarantee from any specific clinic; the exact figure varies. The Mounjaro price landscape in the UK shifted substantially after that list-price change, so quotes you received before autumn 2025 may be outdated.

The key practical point: budget for the maintenance strength, not the starter strength, when working out your annual cost. The difference is real.

Step 2: what headline prices often leave out

A price you see quoted online for Mounjaro may be the medicine cost alone. It is worth reading the small print. Some providers charge separately for the initial consultation, for repeat prescriptions, for clinical reviews before dose increases, and for delivery. Each of those adds to your monthly outgoing. On top of that, services vary in what clinical oversight they offer: does a real prescriber review your repeat before it is sent, or is it automated? Is there someone to contact if you feel unwell at the weekend? These are not small questions when you are injecting a prescription medicine weekly. If you are trying to work out how much each dose of Mounjaro actually costs once those extras are factored in, the total can look quite different from the headline figure. Aftercare is the thing most people only notice when they need it. A lower headline price that excludes clinical support may cost more in anxiety and missed guidance than the saving is worth.

Step 3: where nume sits on price, and why

Spending weeks comparing prices when you have already decided to take your health seriously is frustrating, and we understand that. So here is the plain version: at nume, one price covers your consultation, your prescription, your treatment, delivery, and 7-day aftercare. Nothing is billed separately. We also do not run discount codes, promotional pricing or seasonal offers, Mounjaro is a prescription medicine, and reducing its price to drive purchases is not something a responsible pharmacy does. Our current pricing is shown on the treatment page, updated whenever it changes.

We are not the cheapest option on the market. That is a deliberate choice. What the price buys is a consultation reviewed the same day by a real prescriber (a GPhC-registered Independent Prescriber on our clinical team, not software) identity and weight verification, and the clinical reassessment before every repeat. You can see how we approach clinical oversight on our clinical team page. For more on how the dose steps interact with cost, the Mounjaro doses and cost page is the natural next read.

Step 4: why 'cheapest' is the wrong measure for a prescription medicine

The MHRA has warned publicly about counterfeit weight-loss pens circulating online, including fake tirzepatide pens seized from an illicit UK manufacturing site in late 2025. Prices well below the reported market range are a recognised red flag, along with sellers offering these medicines without a prescription, or via social media channels outside a regulated pharmacy. A question many people ask at this point is whether tirzepatide is cheaper than Mounjaro, and the answer depends on factors that are worth understanding before you compare providers. You can verify any online pharmacy on the GPhC register, and you can report suspect sellers at the MHRA's Yellow Card service. For background on how Mounjaro works and what it is licensed for in the UK, the pillar page covers the clinical and regulatory picture in full.

For a prescription medicine that requires clinical assessment, an ongoing prescriber relationship and a verified supply chain, the question to ask is not which provider is cheapest. It is which provider you would trust to notice if something was wrong. If you are still working out how much a dose of Mounjaro costs across the full titration journey, that page pulls together the figures in one place. NICE's appraisal of tirzepatide, TA1026, sets out the clinical framework within which this medicine is recommended, it is built around supervised treatment, not just supply. That context is worth holding on to when a headline price looks attractive.
