Is Ozempic cheaper than Mounjaro for weight loss in the UK?

You've seen Ozempic listed cheaper, here's what the listing doesn't say

It is true that Ozempic pens circulate at lower private prices than Mounjaro pens in the UK. Mounjaro's list price rose sharply from September 2025, with the highest dose climbing from around £122 to around £330 per four-week pen according to widely reported figures from Eli Lilly's UK pricing announcement. If you want a fuller picture of how Mounjaro vs Ozempic cost breaks down across doses and supply types, the differences are more layered than any single headline figure suggests. The critical detail: Ozempic is not licensed for weight management in the UK. It is licensed for type 2 diabetes. Prescribing it off-label for weight loss is, at best, clinically contentious and, at private clinics, represents a prescribing decision that many responsible practitioners will not make. The MHRA has explicitly stated that GLP-1 medicines should not be used for quick or cosmetic weight loss, and NHS England's guidance on weight-management medicines lists Wegovy and Mounjaro as the two licensed options, not Ozempic. So when you see an Ozempic price, you are not comparing a like-for-like alternative. You are looking at a diabetes medicine that happens to share an active ingredient with a weight-loss medicine. That is a meaningful distinction, not a technicality.

What a legitimate private weight-loss price actually covers, and what many quotes leave out

Private weight-loss treatment in the UK is priced per pen or per month, and the gap between a headline price and the real cost can be wide. Consultation fees, prescription charges, delivery and ongoing clinical support are sometimes bundled in and sometimes not. A prescription for a Prescription-Only Medicine cannot legally be issued without a proper clinical assessment; any quote that appears to skip that step is a red flag worth taking seriously. For context on how Wegovy and Mounjaro compare on price when you are looking at genuinely licensed weight-management options, our Wegovy vs Mounjaro cost comparison breaks down the key differences. The short version: many patients asking whether Mounjaro or Wegovy is cheaper find that Wegovy has historically been priced lower than higher-dose Mounjaro, though trial evidence suggests tirzepatide tends to produce greater average weight loss, a point NICE's appraisal of tirzepatide (TA1026) addresses in its clinical review. Price and clinical suitability are separate questions, and your prescriber weighs both.

Why chasing the cheapest listing is the wrong test for a prescription medicine

For a POM, the lowest price answers the wrong question. The question that keeps you safe is whether the supply chain is legitimate, the clinical assessment is real, and the medicine in your hand is what the label says it is. The MHRA has warned publicly about counterfeit weight-loss pens sold online and via social media, fake pens have contained insulin rather than the stated active ingredient, and in 2025 enforcement operations uncovered roughly 20 million doses of illegally traded weight-loss medicine worth around £45 million, including the first UK site manufacturing counterfeit tirzepatide pens. Understanding why Wegovy is cheaper than Mounjaro in legitimate supply chains also helps explain why pricing that falls dramatically below either benchmark is a warning sign rather than a bargain. Sellers offering these medicines without a prescription, at prices far below the market, or through social media channels are the pattern to avoid.

What nume offers, and why we are not the cheapest option

If you are looking at weight-loss injections and want to understand your actual options, our treatment overview covers what is licensed, how the clinical pathway works, and what eligibility looks like in practice. At nume, one price covers the consultation, the prescription, the medicine, and next-working-day delivery, order before midday on a working day and, once our prescriber has reviewed and approved your consultation, your treatment goes out the same day. We do not run discount codes or promotional pricing for these medicines, and for anyone still weighing up what's cheaper between Mounjaro or Ozempic, the licensed pathway and clinical suitability should come before the price comparison. We are not trying to be the cheapest option on a comparison table, because for a prescription medicine that figure tells you almost nothing useful. Our prescribers (you can read about our clinical team at our clinical lead's profile) personally review every consultation and every repeat order. If you have questions before you start, our FAQs cover the most common ones, and our team is reachable seven days a week.
