How Much Does Mounjaro Cost Per Month in the UK?

What does Mounjaro actually cost per month in the UK right now?

Privately, Mounjaro is priced per pen — and each pen covers four weekly doses. So the monthly figure you see advertised is, in practice, one pen per billing cycle. Since Eli Lilly raised its UK list prices from 1 September 2025, the cost has risen noticeably at higher doses. If you want a detailed sense of how much Mounjaro is per month across different doses and providers, we cover that in full elsewhere, but broadly, monthly prices have typically sat somewhere between £149 and £375, depending on the dose and who you're buying from, though those figures are widely reported and will shift as the market adjusts.

One thing worth clearing up: many people search expecting a single flat price. Mounjaro is available in six strengths (2.5mg through to 15mg), and the cost rises with the dose. The 2.5mg starter pen costs considerably less than the 15mg maintenance pen. So a quoted price that doesn't specify a dose is difficult to compare with anything else. What 5mg Mounjaro costs, for example, sits meaningfully below what the higher strengths cost, a distinction that matters when you're planning ahead for several months of treatment.

It is also worth knowing that Mounjaro is titrated over time. Most people don't stay at the starting dose, so a realistic budget for a course of treatment should account for dose increases across the months, not just the first pen's price. Our prescribers discuss what that trajectory might look like during your consultation.

What do headline Mounjaro prices tend to leave out?

Advertised per-pen prices don't always include everything you'll actually need. Some providers charge separately for the initial consultation, the prescription, any follow-up clinical reviews, or delivery. Aftercare (someone qualified to call if you have a reaction, a question about side effects, or a concern about how treatment is going) isn't a luxury; for a prescription medicine, it's part of safe use.

Delivery is another one. Mounjaro must be kept refrigerated, so getting it to you safely and promptly is a logistical requirement, not just a perk. A provider that charges separately for tracked cold-chain delivery can make what looked like a lower starting price considerably less competitive once you add everything up. A fuller breakdown of Mounjaro pricing covers these variables in more detail.

Clinical re-review before every repeat order is something our prescribers do as standard. Not all services do. For a prescription medicine where your dose is likely to change and your health picture needs regular checking, that oversight matters. It's the kind of thing that disappears from a price comparison table but doesn't disappear from your experience of treatment.

How does nume approach Mounjaro pricing?

We're not the cheapest. That's a deliberate position, not an oversight. Our single transparent price covers the consultation, the prescription, the treatment itself, delivery, and aftercare, nothing added at checkout, no subscription locking you in, no auto-renewal. Every repeat order is clinically re-reviewed before it's processed.

You can see exactly what treatment costs on our treatment page. We don't print per-pen figures in articles because they date quickly and a decontextualised number tends to mislead more than it helps. What we can say is that the price you see there is the price you pay. Our pharmacy is GPhC-registered (registration 9012878, verifiable at pharmacyregulation.org), and every consultation is read by a real clinician, you can read about our clinical team if you'd like to know more.

We also don't run discount codes, vouchers or promotional offers. If you've seen a code promising reduced-price Mounjaro from an unverified seller, that's a meaningful red flag for a prescription medicine. Mounjaro should only reach you through a licensed UK supply chain, following a genuine clinical assessment. The MHRA's Yellow Card scheme allows you to report any suspect seller.

Is 'cheapest per month' the right question to ask?

For most purchases, price is a reasonable shorthand for value. For a prescription medicine, it isn't, at least not on its own. The MHRA has warned publicly about counterfeit weight-loss pens circulating online and via social media, some of which have contained insulin rather than the labelled medicine. Sellers offering these treatments without a prescription, at prices far below the private market, are a category to avoid rather than pursue. The MHRA's Drug Safety Updates cover this pattern in detail.

The right question is probably closer to: does this provider have a genuine clinical process, a verifiable pharmacy registration, and a supply chain you can trust? Understanding the Mounjaro price per month in that fuller context, factoring in consultation, aftercare, and supply chain integrity, gives you a much more useful basis for comparison than a headline figure alone. A note on Mounjaro discounts covers what legitimate pricing does and doesn't look like in more detail, if that's useful.

Speak to our prescribers through a free consultation. There's no obligation, and it's the clearest way to understand whether Mounjaro is clinically suitable for you and what a realistic Mounjaro cost per month would look like across your treatment.
