What does tirzepatide cost per month in the UK?

How is UK private tirzepatide pricing actually structured?

In the UK private market, tirzepatide is priced per pen. Each pen contains four weekly doses, so one pen covers one month of treatment. The dose you are prescribed determines the price: lower doses cost less, higher doses cost considerably more, and since Eli Lilly's September 2025 list-price revision, the gap between the two ends of the range has widened significantly. If you want a clear picture of what that looks like in practice, the page covering Mounjaro cost per month breaks down reported private prices by dose, which have run roughly £149 to £375 depending on dose and provider, though individual services set their own retail figures above the list price.

It is worth knowing that tirzepatide treatment starts at 2.5mg (a dose whose job is to help your system adjust, not to deliver the full therapeutic effect) and titrates upward over several months. So the cost you face at month one is not the cost you will face at month six, and comparing a starter-dose price to a maintenance-dose price across different providers is comparing very different things. The 5mg cost page breaks down that particular step in more detail.

One more structural point: these medicines are available on the NHS through a phased rollout, currently limited to people with high clinical need and specific comorbidities. If you do not yet meet the NHS criteria (or you would rather not wait) private treatment through a regulated pharmacy is the alternative. Our weight-loss overview explains both routes plainly.

What do headline prices often leave out?

A price displayed on a treatment page is usually just the pen. Whether anything else is included depends entirely on the provider, and it is surprisingly variable.

Some services charge a separate consultation fee, payable whether or not you are approved. Others add a prescription-writing charge on top. Delivery is not always free, and expedited or tracked options can carry a premium. Aftercare (follow-up clinical support between doses, help if you have a reaction, review before a dose increase) is sometimes bundled, sometimes sold as an add-on plan, and sometimes simply absent.

When you add those components back in, a headline price that looks lower can end up costing more in practice. The honest comparison is total monthly spend for treatment plus everything required to take it safely. A breakdown of what the monthly cost really covers can help you build that comparison accurately.

There is also the question of clinical rigour. A review that takes ten seconds and ticks boxes is not the same as a prescriber actually reading your answers. That distinction does not show up in the price column, but it shapes whether the treatment is appropriate for you at all.

Where does nume sit on price, and what does that include?

We do not compete on price. That is a deliberate choice, not an oversight. At nume, a single transparent price covers your consultation, the prescription, the medicine, and free next-working-day tracked delivery, plus seven-day-a-week aftercare and a clinical review before every repeat order. Nothing is hidden, and there is no subscription pulling the next payment out automatically. Current treatment pricing is shown on the treatment page.

Every consultation is personally reviewed by a GPhC-registered Independent Prescriber, a real clinician reads your answers the same day, not a scoring algorithm. Before any dose increase, our prescribers check the evidence. Transfer patients are asked to provide documentation of their current treatment. You can verify our pharmacy on the GPhC register at any point; our about page links directly to our registration.

That pen you keep in the fridge door alongside your orange juice should come from a supply chain you can trace. Our medicines are sourced through the licensed UK supply chain, via Eli Lilly's authorised distributors. That is what the price buys.

Why is 'cheapest' the wrong test for a prescription medicine?

Mounjaro is a prescription-only medicine. UK law exists precisely because medicines of this kind carry real risks (interactions, contraindications, conditions that need to be excluded before treatment starts) that require a trained prescriber to assess. The MHRA has warned publicly about fake weight-loss pens sold online, some containing insulin rather than tirzepatide, after large enforcement operations including a counterfeit tirzepatide manufacturing site raided in Northampton in October 2025. Approximately 20 million doses of illegally traded weight-loss medicines worth around £45m were seized in 2025 alone. You can report suspect sellers via the MHRA's Yellow Card scheme.

The right question, then, is not which provider charges the least, it is which provider gives you a genuine prescription from a real clinician, genuine medicine from a verified supply chain, and genuine clinical support if something does not feel right. Price is one variable in that picture, not the primary one.

If you want to understand the broader cost context across the Mounjaro range, the Mounjaro monthly cost page covers every licensed dose. For a straight price overview, our Mounjaro price page sets out what is included plainly. And if you have specific questions about your situation, our team is available seven days a week.
