What Are the New Mounjaro Prices, and What Should You Expect to Pay?

Step 1: Understand what changed, and why prices vary across providers

Before September 2025, the highest-dose Mounjaro pen carried a UK list price of around £122 for a four-week supply. That figure rose to around £330 after Eli Lilly's price adjustment, and private clinics and pharmacies have priced accordingly. The full picture of current Mounjaro pricing by dose varies because lower doses sit at the bottom of that range and higher doses at the top.

A question our prescribers hear most weeks is whether prices will fall again. The honest answer is that no confirmed reduction has been announced; if you are trying to plan ahead, our page covering what the new price of Mounjaro is expected to be is hedged for a reason, list prices can shift, and any figure in an article from six months ago may already be out of date. The treatment page on our site shows current pricing; body copy across the web, including this page, deliberately avoids quoting per-pen figures that could be wrong by the time you read them.

What the range tells you is this: if you want a reliable point of reference before reading further, our up-to-date guide to new Mounjaro prices is kept current as the market moves, which matters because figures from even a few weeks ago can already be misleading. And if you see Mounjaro offered at a price that sits well below £149 a month from an unverified source, that is a red flag worth taking seriously, more on that in a moment.

Step 2: Look past the headline number, what a quoted price often leaves out

A headline monthly figure from some providers covers the medicine only. Consultation fees, prescription charges, delivery costs and any ongoing clinical support can all be billed separately. Add those up and the gap between providers narrows or reverses.

It is worth understanding what genuine clinical oversight involves: a prescriber reviewing your health history, confirming eligibility, checking for contraindications and, at each repeat, re-assessing your progress. That work takes time. Providers who absorb it into one price are not doing less, they are pricing differently.

The breakdown of what goes into a Mounjaro private prescription price is a useful read if you want to compare providers fairly. NICE's appraisal of tirzepatide sets out the clinical framework that responsible prescribing follows, and it gives a sense of how much is involved beyond dispensing the pen itself.

Step 3: Know what you are actually comparing when you compare prices

At nume, we are not the cheapest option and we made that choice deliberately. One price covers your consultation, prescription, the treatment itself, next-working-day DPD delivery and seven-day aftercare. Nothing is added at checkout. There is no subscription; every repeat order goes back to a real prescriber for a clinical re-review before it is approved.

Our prescribers are GPhC-registered Independent Prescribers. Your consultation is read by a person on the day you submit it, not processed by software. You can verify our pharmacy on the GPhC register directly: registration number 9012878 at pharmacyregulation.org.

For the people most suited to us, the maths is straightforward: a single transparent price with no add-ons, from a pharmacy you can check. More detail on how our service works is on the about us page.

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

The MHRA has been explicit about the risks of sourcing GLP-1 medicines through unverified channels. In October 2023, the agency warned publicly about counterfeit weight-loss pens being sold online and via social media, some containing insulin rather than the stated medicine, leading to hospitalisations. Enforcement through 2025 included seizures of around 20 million doses of illegally traded weight-loss medicines worth approximately £45 million, and the first illicit UK site producing counterfeit tirzepatide pens was raided.

For a prescription-only medicine, the price question that actually matters is not 'who charges least' but 'am I getting genuine medicine through a regulated supply chain, reviewed by a qualified prescriber'. Those two things are not optional extras, they are what makes treatment safe. You can report suspect sellers through the MHRA's Yellow Card scheme.

If you want to understand what private Mounjaro treatment looks like as a full package (eligibility, process, cost context) start with the free consultation. There is no charge to find out whether you qualify, and the clinical review happens the same day. If you are still weighing up the numbers beforehand, our guide to what the new Mounjaro prices will be and the companion page on the Mounjaro new price set out the current picture as clearly as we can.
