How Much Does a Course of Mounjaro Cost in the UK?

You've found a monthly price online — here's what it may not include

Picture this: you've searched around, spotted a figure that looks reasonable, and you're ready to go. Then you notice the consultation costs extra. Or the prescription fee is separate. Or delivery is added at checkout. This is common across the private weight-loss market, and it matters because a course of Mounjaro isn't a gym membership you can cancel after a bad month, it's a prescription medicine with a clinical process attached.

When Eli Lilly raised its UK list price from 1 September 2025, the highest-dose pen moved from around £122 to around £330 at list. Private providers set their own prices on top of that, which is why you'll see figures reported as widely as £149 to £375 per month depending on dose and service. If you want to understand how much Mounjaro costs across doses and services, the picture is more detailed than any single headline figure suggests. What headline prices often omit: initial consultation charges, prescription fees (which can be billed per issue), aftercare and dose-review support, and delivery. Add those together and the gap between the cheapest-looking option and a genuinely all-in price can close faster than the numbers suggest. For a closer look at how individual doses are priced, the Mounjaro price breakdown on our site sets it out plainly.

The NICE appraisal of tirzepatide (TA1026) confirmed its clinical value for weight management in adults, that appraisal also shapes what the NHS will eventually offer and when, which is relevant if you're weighing private costs against waiting.

What the starting dose costs, and why the dose changes

Mounjaro treatment begins at 2.5mg. That first pen exists so your system adjusts gradually; it's the tolerability phase, not the phase where most clinical effect is expected. As treatment progresses, most people move through 5mg, 7.5mg, and higher doses in steps typically four weeks apart, guided by their prescriber. Each step may carry a different price.

That means "how much is a course" doesn't have a fixed answer, it depends on which dose you're on, how long you stay there, and whether you continue to maintenance. Some people reach their target weight at a lower dose; others stay longer at a higher one. Your prescriber determines the right pace, not a pre-set timetable.

If you want to understand what specific doses cost, pages like how much 5mg Mounjaro costs and the 2.5mg starter cost break it down at each step. For a broader look at the full dose range, this page on per-dose pricing covers the picture across the titration schedule.

What stays constant at nume: one price, whatever the dose, covers consultation, prescription, the treatment itself, and delivery. Current pricing is shown on our treatment page, we don't print per-pen figures here because they're updated when needed and we want you to see what's live.

Why we're not the cheapest option, and what that buys you

We'll be straightforward: cheapest isn't a race we entered. The single price you pay at nume covers the free consultation, the prescription, the medicine, and free next-working-day delivery via DPD, tracked to your door in a plain, unmarked box. No follow-up fees when your dose increases. No separate charge if you need to speak to the team. Aftercare is available seven days a week.

Every consultation is read by a real clinician. A named GPhC-registered Independent Prescriber reviews your answers personally on the day you submit them, not a decision tree, not an automated system. Our pharmacy holds GPhC premises registration number 9012878, which you can verify on the regulator's public register. Before every repeat, there's a fresh clinical check. That's the standard we think a prescription medicine warrants.

There are no discount codes, no seasonal promotions, no vouchers. If you see a code circulating for Mounjaro from an online seller, that's a prompt to look more carefully at what they're actually offering. The MHRA has warned publicly about fake weight-loss pens sold through unverified channels, some containing insulin rather than tirzepatide. A price that looks too good is worth scrutinising before anything else.

The right question isn't the cheapest monthly figure, it's clinical safety and supply

For a medicine that requires a prescription, the cost question and the safety question are the same question. A low price from an unverified seller who dispenses without a proper clinical assessment isn't a bargain, it's a different product, effectively. The NHS's own guidance on weight-management injections is clear that these treatments should sit within a clinical framework, with a prescriber assessing suitability and ongoing progress.

The questions worth asking of any provider: is the pharmacy GPhC-registered and verifiable? Does a qualified prescriber personally review each consultation? Is the medicine sourced through the UK-licensed supply chain? Are repeat orders clinically reviewed, or just auto-dispatched? The answers to those questions matter more than whether one service undercuts another by £20.

If you're weighing up whether Mounjaro is the right treatment for you at all, our Mounjaro overview covers eligibility, how it works, and what the trial evidence shows. Or if you'd prefer to explore the full range of options, our weight-loss treatments page sets out what's available. Either way, a consultation is free, and the prescriber who reads it will give you a straight answer about whether treatment is right for you.
