What Mounjaro actually costs per month — and what that price should include

Step 1: Understand what UK private pricing actually reflects

Mounjaro is supplied as a once-weekly KwikPen, so a monthly cost generally means one pen covering four doses. Eli Lilly raised its UK list price from 1 September 2025; the highest-dose pen's list price rose from around £122 to around £330, and private providers have adjusted accordingly. Reported private prices since then run roughly £149 to £375 per month depending on the dose and provider, figures that circulate widely but should always be treated as indicative rather than fixed.

The starting dose is 2.5mg, which exists to let your body adjust before the prescriber steps things up. That means your first month's cost will sit at the lower end of the range, and what you pay in month four or six may look quite different. If you're trying to work out how much Mounjaro is per month across the full treatment course, it's worth reading up before you commit to any provider, because a monthly number quoted in isolation rarely covers the whole journey.

Step 2: Work out what the headline price actually includes

This is a question our prescribers hear most weeks: someone has found a lower monthly price elsewhere and wants to know whether it's comparable. Often it isn't. Headline prices sometimes exclude the consultation fee, the prescription charge, delivery costs, or any ongoing clinical support, each of which can be billed separately on top. Understanding the true Mounjaro cost per month means adding up every line item, because a £149 pen price plus a £30 consultation plus a £9 delivery charge is not a £149 month.

Beyond the line items, consider what happens when you need a dose review, have a question at the weekend, or need to transfer to a higher strength. Some providers charge per interaction; others include nothing beyond dispensing the medicine. For a prescription medicine taken weekly over months, aftercare isn't an optional extra.

The Mounjaro price comparison page sets out the categories worth checking side by side. If a provider's website doesn't list what their price includes, that's useful information in itself.

Step 3: Know what you're paying for at nume, and why we've priced it the way we have

nume is not the cheapest option in the UK market. That's a deliberate choice, not an oversight. One transparent monthly price covers your free consultation, the prescription, your treatment, and free next-working-day tracked delivery via DPD, in plain, unbranded packaging. There are no subscription commitments. Every repeat order is clinically re-reviewed by a GPhC-registered Independent Prescriber before anything is dispensed, and our prescribers are available for aftercare seven days a week.

You can verify our pharmacy on the GPhC register at registration number 9012878. Every medicine we dispense comes through the licensed UK supply chain, including our authorised supplier relationship with Eli Lilly. Current treatment pricing is shown on our treatment and consultation page.

We don't run discount codes, vouchers or promotional pricing for Mounjaro. A prescription medicine supplied at an unusually low price (especially with a discount code attached) is a red flag, not a bargain. The MHRA has warned publicly about counterfeit weight-loss pens sold online, some containing insulin rather than tirzepatide. Genuine supply costs what it costs, and anyone researching what Mounjaro costs per month from a legitimate provider will find that reflected consistently across the licensed market.

Why 'cheapest' is the wrong question for a prescription medicine

Price is a reasonable thing to consider. It's the wrong thing to optimise for. Mounjaro requires clinical assessment before it can be prescribed, which means the service behind the medicine matters as much as the medicine itself. A prescriber who reviews your health history, checks for contraindications, monitors your response and adjusts your dose appropriately is not an add-on, it's the legal and clinical requirement that makes the treatment safe.

The NICE appraisal of tirzepatide (TA1026) and the NHS England guidance on weight-management injections both make clear that these medicines work within a framework of clinical oversight. That framework has a cost. What you're really comparing when you compare providers is the quality and completeness of that oversight, not just the price of the pen.

If you'd like to understand more about how the treatment works before thinking about cost at all, the weight-loss treatment overview is a good place to start. Some patients also find it helpful to review what a £99 per month Mounjaro offer actually involves before drawing comparisons, since the structure of those deals varies considerably. Or if you have specific questions about how we assess suitability, our frequently asked questions cover the most common ones. When you're ready, speak to our prescribers, the consultation is free, and it takes the same day to hear back.
