How Much Is 10 mg Mounjaro, and Is the Price Telling You the Right Thing?

The decision you're really making at 10 mg

By the time most people reach 10 mg, they've already been on Mounjaro for several months. The licensed titration schedule starts at 2.5 mg and moves up in steps, and if you're curious about how much the 2.5 mg starting dose costs relative to where you are now, that page sets out the detail; 10 mg sits in the middle of the range, above 7.5 mg and below 12.5 mg and 15 mg. At this stage you're not buying a starter product, you're continuing a supervised course, and the clinical check before this pen ships matters just as much as it did on the first one.

When you're comparing prices at this dose, you're not comparing like-for-like unless every quote includes the same components. A consultation fee, a prescription fee, a clinical review of your progress, and delivery can each be charged separately by different providers. Some charge nothing upfront and recoup those costs elsewhere; others bundle everything. Neither approach is automatically better, the question is whether the total is honest and whether the clinical process behind it is real.

You can find background on how Mounjaro is priced across the dose range if you want a broader picture before focusing on 10 mg specifically.

What a 10 mg Mounjaro listing may not include

Headline prices in search results tend to show the medicine cost alone. What they often leave out: an initial or ongoing consultation charge, a prescription-writing fee (separate from the consultation at some providers), delivery (which can run to £5–£15 per shipment) and any fee for a clinical review when you move between doses. At 10 mg you've almost certainly moved up at least twice from where you started, and each of those steps should, under good clinical practice, involve a check of your weight, how you're tolerating the medicine, and whether the next dose is appropriate.

There's also the question of aftercare. If something doesn't feel right (persistent nausea beyond the usual adjustment window, an injection-site reaction, a question about whether to delay a dose) who do you call? Some providers don't offer structured aftercare at all. Others charge for it. Worth factoring in before the cheapest listing wins.

The full breakdown of what private Mounjaro costs covers these components in more detail, including how post-September 2025 list price changes affected the market.

Why 10 mg costs more than earlier doses, and what that means for your budget

Higher Mounjaro doses contain more active medicine per pen, and Lilly's UK list pricing scales with dose. If you're wondering how much it costs to manufacture Mounjaro, that context can help explain why the price gap between doses is structured the way it is. The September 2025 price increase was steepest at the upper end of the range: the 15 mg pen's list price reportedly rose from around £122 to around £330, as widely reported at the time. The 10 mg pen sits below the top, but the same directional logic applies, it costs more than the 5 mg pen you may have started on.

If budget is a genuine constraint, it's worth discussing that openly with your prescriber. Dose isn't just a ladder to climb as fast as possible; some people stay at 10 mg for longer than the minimum titration window because it's working well and tolerability is good. That's a clinical conversation, not a commercial one. Our clinical team profile gives a sense of who's reviewing these decisions at nume.

For context on how the 10 mg price compares to doses immediately above and below it, the 7.5 mg cost page and the 15 mg page set out the market picture at those strengths.

The right yardstick isn't price, and here's why that matters

Mounjaro is a prescription-only medicine. The MHRA has been clear, and enforcement actions have followed, that fake GLP-1 pens are being sold online and through social media. Counterfeit tirzepatide pens have been seized in significant quantities; in October 2025 the first UK illicit manufacturing site producing them was raided. The MHRA's guidance is unambiguous: buy only through pharmacies you can verify on the GPhC register.

A legitimately dispensed 10 mg Mounjaro pen has been through a licensed UK supply chain, prescribed by a qualified clinician who has reviewed your case, and dispensed by a GPhC-regulated pharmacy. You can verify any online pharmacy at pharmacyregulation.org/registers; nume's GPhC premises registration is 9012878. A price that looks notably lower than the market range deserves a question: what's missing?

At nume, we're not trying to win a price comparison. One transparent charge covers everything, consultation, prescription, the medicine, and next-working-day delivery. Your pen arrives in a plain box via DPD, tracked to your door, with no indication of what's inside. That's a deliberate choice, not an afterthought. The full list of what's included in treatment is on the consultation and treatment page, and a free consultation with our prescribers is the right starting point if 10 mg is where you're headed next.
