How Much Is Mounjaro on Prescription in the UK?

Step 1: understand what a private Mounjaro prescription really costs

Private Mounjaro prescription pricing in the UK changed substantially from autumn 2025 after Eli Lilly revised its list prices. The highest-strength dose saw its list price rise from roughly £122 to around £330 per four-week pen. Private providers price above the list price to cover their own clinical and dispensing costs, which is why published retail figures across the market now commonly sit between £149 and £375 a month, varying by dose, provider, and what the quoted fee actually includes.

These are the only per-pen cost figures you will find cited in our content, drawn from widely reported coverage of the Lilly pricing change. A lower dose like 2.5mg typically costs less than a maintenance dose at 10mg or above, so the figure you see on a price page only makes sense once you know which dose it refers to. Our overview of Mounjaro pricing breaks this down dose by dose so you can compare like with like.

One thing worth noting early: Mounjaro prescription cost and Mounjaro total cost are not the same question. If you are also wondering how much Mounjaro costs on the NHS, that is a separate question worth understanding before you decide whether to go private. The prescription is one line item; what surrounds it varies enormously between services.

Step 2: work out what the headline price does and does not include

This is where pricing comparisons between providers get genuinely complicated. A quoted monthly figure might cover the pen and nothing else, with consultation fees, prescription fees and delivery charged separately. Or it might bundle some of those elements but not others. A question our prescribers hear regularly is why two apparently similar prices produced very different totals at checkout.

Common extras that are not always bundled: an initial consultation fee (sometimes £25–£50 separately), a prescription-writing fee, delivery charges, dose-review appointments before a titration step, and ongoing clinical support between doses. If you are using a service that requires a subscription, there may also be a monthly platform fee on top of the medicine price. How Mounjaro subscriptions work is worth reading if you have seen those models advertised, because the commitment structure affects total cost considerably.

For the purposes of comparing any two services honestly, the right number to use is the total cost of treatment for a full month, including every fee, at the dose you expect to reach. That is a harder figure to find, but it is the only one that means anything.

Step 3: understand where nume sits, and why

We are not trying to win on price. Cheapest is not a race we entered, and that is deliberate. What we offer is one transparent figure that covers the consultation, the prescription, the treatment, and free next-working-day delivery, no extras, no subscription, no auto-renewal. Every repeat order is clinically re-reviewed before dispatch; nothing ships automatically.

Once your consultation is approved, your pen is dispatched the same day if you order before noon on a weekday. DPD deliver it the next working day; the tracking link arrives on your phone and the box itself is plain, with nothing on the outside to say what is inside. The pen arrives ready to use alongside its Patient Information Leaflet. Why we do not offer subscriptions explains the reasoning if you want the longer version.

Our clinical team reviews every application personally. No algorithm approves you; a named GPhC-registered Independent Prescriber reads your answers the same day. Current treatment prices are shown on our weight-loss treatments page.

Step 4: apply the right test before choosing any provider

For a prescription medicine, the cheapest listing is the answer to the wrong question. The question that matters is whether the supply chain is genuine, the clinical assessment is real, and the pharmacy is registered. Fake weight-loss pens have been seized at scale in the UK, the MHRA has a Yellow Card mechanism for reporting suspect sellers, and its public warnings make clear that pens sold via social media or at prices well below market rate carry real safety risks.

Any legitimate UK online pharmacy can be found on the GPhC register. Ours is listed under registration number 9012878, you can verify it directly at the GPhC pharmacy register in about thirty seconds. If a seller cannot point you to a verifiable GPhC registration, that alone is reason to stop. Sellers offering these medicines without a full clinical assessment are operating outside the law.

The NICE guidance on tirzepatide (Mounjaro) sets out the clinical criteria for who the medicine is appropriate for, you can read it at NICE technology appraisal TA1026. A prescriber's job is to apply that kind of clinical judgement to your individual circumstances, and if you want a clear picture of how much Mounjaro costs across all the variables before you begin, that page brings it together in one place. That judgement is what a genuine private prescription actually buys you, and it is the part that matters most.
