What does the Mounjaro jab cost — and what should that price include?

How UK private pricing for Mounjaro actually works

Private pricing for tirzepatide reflects several things at once: the medicine itself, whichever clinical services wrap around it, and the provider's margin. Prices are typically quoted per four-week pen, since each KwikPen delivers one dose a week across a month. Treatment starts at 2.5mg (a tolerability dose) and most people move through higher strengths over time, so the monthly cost tends to rise as the dose does.

The market range reported since Lilly's September 2025 price change sits roughly between £149 and £375 per month depending on dose and provider. Those figures come from widely reported industry coverage of the list-price adjustment and are hedged here for good reason: private prices shift, individual circumstances affect what you pay, and some providers quote the starting dose only. When you see a low headline figure, it almost always reflects the 2.5mg starter pen, not the maintenance dose you're likely to be on for the majority of your treatment.

The full breakdown of what drives that monthly figure is worth reading before you compare providers, because the same dose from two different pharmacies can represent very different levels of clinical involvement.

What a headline price often leaves out

A question our prescribers hear most weeks is some version of: "I've seen it for X, why is yours different?" The honest answer is that a bare medicine price and a full-service price are not the same thing, even when the pen is identical.

Common extras that may not be included in a quoted price: an initial consultation fee (charged separately by some providers), the prescription charge itself, delivery costs, and any ongoing clinical review before a repeat order goes out. If you want a clear picture of the Mounjaro jab price alongside what that figure typically includes or excludes, it helps to look at each component individually before committing to a provider. Some services also charge separately for dose-escalation support or treat aftercare as a premium add-on.

Under UK pharmacy law, Mounjaro can only be dispensed against a valid prescription, and that prescription must follow a genuine clinical assessment. If a price seems to sidestep that process entirely, that is worth noting. The MHRA has issued public warnings about fake weight-loss pens sold through unverified online channels, and the MHRA's Yellow Card scheme is the place to report anything suspicious. Legitimate supply always starts with a prescriber's clinical judgement.

You can check whether any online pharmacy is properly registered in under a minute using the GPhC pharmacy register. It is one of the most practical things you can do before handing over payment details.

What nume charges, and why the price is structured as it is

We are not the cheapest option. That is a deliberate decision, not an oversight. The single price you pay at nume includes your consultation, the prescription, the medicine, and next-working-day DPD delivery, tracked, in plain packaging, at no extra charge. Seven-day aftercare from the clinical team is also included. There are no subscription arrangements and no auto-renewals; every repeat order is reviewed by a prescriber before it is approved and dispatched.

Consultations are read the same day by a GPhC-registered Independent Prescriber. A real clinician reviews your answers, not a queue for automated decision software. For patients who order before 12pm on a working day and are clinically approved, treatment is dispatched the same day.

Our current treatment pricing is shown on the weight-loss treatments page. We do not publish per-pen figures in editorial content, because a price without the clinical context around it answers the wrong question.

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

Price comparison makes sense for most things you buy online. For a prescription-only medicine, it answers a different question than the one you actually need answered. The relevant questions are: is this pharmacy GPhC-registered, is there a genuine prescriber involved, is the medicine coming through the licensed UK supply chain, and what happens if you have a concern mid-treatment?

NICE's appraisal of tirzepatide, TA1026, sets out the clinical criteria under which this medicine is recommended, and it is unambiguous that treatment should happen alongside clinical oversight, not independently of it. People researching how much the Mounjaro jab costs across different service models often find that a small difference in monthly cost matters much less than whether the clinical infrastructure behind their supply is robust.
