Cheapest Mounjaro at Cured Pharmacy: Price by Dose

Published: 10 November 2026

Each Mounjaro KwikPen holds four weekly doses, so one pen covers a month of treatment. Prices below include your online consultation and delivery.

What the first four months typically cost

Most patients start on 2.5mg and step up every four weeks if the dose is well tolerated. Following that schedule takes you to 10mg in the fourth month. Your first pen is £124.99 with the new-patient discount. Your prescriber decides when, or whether, to increase your dose, and many patients settle on a lower maintenance dose.

Cheapest Mounjaro UK: How Our Prices Compare

This table compares the price of one Mounjaro pen (four weekly doses) across UK online pharmacies. Our prices were checked against our live store on 25 October 2026. The Cured Pharmacy column shows the first-order price after £20 off with code Weightlossnew. The other columns are each provider's standard advertised price, before any new-customer offers, as published in Oxford Online Pharmacy's September 2026 comparison of 15 UK providers, so they may have changed since. The lowest price at each strength is in bold.

With the £20 first-order discount, our price is lower than every other provider's standard price at all six strengths. Repeat orders are charged at our standard prices (£144.99 at 2.5mg, £179 at 5mg, £220 at 7.5mg, £245 at 10mg, £270 at 12.5mg and £287 at 15mg), which are still the lowest at 7.5mg, 10mg, 12.5mg and 15mg; at 2.5mg Oxford Online Pharmacy is £1.03 cheaper, and at 5mg Medino is £9.01 cheaper.

First-order offers differ too. Our code Weightlossnew takes £20 off a new patient's first order, bringing 2.5mg to £124.99. Other pharmacies run their own new-customer offers, which are not included in their columns above (Oxford Online Pharmacy, for example, advertises £20 off with code BNEW20). Prices change often, so always check the total at checkout – including consultation, delivery and any review fees – before you order.

How we check prices: our own prices are checked against our live store pricing for every dose, and the Cured Pharmacy column shows the first-order price after £20 off with code Weightlossnew. Competitor prices are the standard advertised price for one pen at each strength, as published by Oxford Online Pharmacy in September 2026, before any new-customer offers. We re-check this page at least monthly and update it when prices change.

Why Mounjaro Prices Vary Between UK Pharmacies

Every UK pharmacy buys the same Eli Lilly pen, so price differences come from how each one sets its margin and what it bundles in. In September 2025 Eli Lilly raised the UK list price of Mounjaro, with the highest dose rising from £122 to £330 a month before pharmacy rebates.[7] Since then, private prices have varied widely depending on the rebate terms each pharmacy has and how much of the increase it passes on.

Pricing models also differ. Some pharmacies show a low pen price and then add a consultation fee, delivery charge or monthly review fee. At Cured Pharmacy (GPhC 9012511), the prescriber consultation and delivery are included in the price you see above.[1]

Extra costs to check before you buy

When comparing pharmacies, ask for the total monthly cost and check whether it includes: the prescriber consultation, tracked cold-chain delivery, follow-up reviews when your dose changes, pen needles, and a sharps bin. A pen that looks £15 cheaper can end up costing more once these are added.

How to Check You're Getting Genuine Mounjaro

A low price is only worth having if the medicine is genuine. Check that the pharmacy is on the GPhC register and names its superintendent pharmacist. At Cured Pharmacy that is Tarun Kumar (GPhC 2233073), who oversees dispensing so every tirzepatide pen is UK-licensed and traceable. Counterfeit weight loss injections are sold online and may contain the wrong ingredient or none at all.[2]

Genuine Mounjaro comes as a sealed Eli Lilly KwikPen with a batch number, and it must be kept at 2–8°C, so it should arrive in temperature-controlled packaging. If a price is far below what registered pharmacies charge, treat it as a warning sign.

Red flags when comparing Mounjaro prices

Avoid any seller that doesn't require a prescriber consultation, as tirzepatide is a prescription-only medicine. Be wary of websites with no GPhC registration number, no named pharmacist, no UK address, or payment by bank transfer or crypto only. Social media sellers and anyone offering "compounded" or "generic" tirzepatide are not legitimate UK suppliers.

How Your Dose Affects Monthly Cost

Mounjaro comes in six strengths – 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg – each taken once a week. In the SURMOUNT-1 trial, gradual dose increases over around 20 weeks helped tolerability, with average weight reductions of 15–20% of body weight at higher doses.[3]

Higher strengths cost more per pen, but staying on the starter dose just to keep costs down usually means less effective treatment. Your prescriber will recommend the lowest dose that keeps working for you, and many patients maintain their weight loss on a mid-range dose rather than 15mg.

Cheapest Mounjaro Per Month, 6 Months and a Year

One Mounjaro pen holds four weekly doses, so a pen is roughly a month of treatment. The cheapest Mounjaro per month is the 2.5mg starter pen at £144.99 (£124.99 for new patients), rising to £287 a month at 15mg. What you pay over a longer period depends mainly on how quickly your prescriber steps up your dose.

Six months of Mounjaro on a standard step-up schedule

This table assumes one pen a month, stepping up a strength each month from 2.5mg to 15mg, with the new-patient code applied to the first pen. Most people do not follow this schedule exactly, and your prescriber decides your dose.

A year at one dose

If you stay on one strength, 13 pens cover a year (52 weekly doses). Standard prices:

Many people settle on a lower maintenance dose once they reach their goal, which is where most of the long-term saving comes from. If you are weighing multi-month packs, see our Mounjaro bundle prices.

Mounjaro vs Other Weight Loss Treatments on Price

Tirzepatide acts on both GIP and GLP-1 receptors, and in head-to-head trials it produced greater weight reduction than semaglutide (Wegovy) at comparable timepoints, though individual responses vary.[4]

Wegovy (from £69), Saxenda (from £68) and Orlistat (from £32) have lower starting prices. Orlistat works by reducing fat absorption rather than appetite and typically produces more modest weight loss. Your prescriber will recommend the most suitable option for your health, goals and budget. For a fuller breakdown of how these treatments compare, see our Mounjaro price comparison UK 2026 page.

Discount Codes and Other Ways to Pay Less

New patients get £20 off their first weight loss order with code Weightlossnew. You still complete the same clinical consultation, and a prescriber has to approve treatment before anything is dispensed – based on your BMI (typically 30 or above, or 27 or above with a weight-related condition), medical history and current medicines.[5]

If you're already a patient, our refer-a-friend scheme gives you and the person you refer £40 off weight loss treatment. Over the longer term, the biggest saving usually comes from staying on the lowest dose that keeps working for you, which your prescriber reviews at each reorder.

What's Included in Our Price

The price you pay at Cured Pharmacy covers a free online consultation with a UK-registered prescriber, a genuine Eli Lilly Mounjaro KwikPen, discreet delivery in temperature-controlled packaging, and ongoing clinical support for dose changes or side effects. There's no separate consultation or review fee.

Most UK orders arrive within 24–48 hours with tracking, and next-day delivery is available. Our pharmacy team is available on +44 116 4646009 for questions about injecting, storage or reorders.[6]

Prescription renewals

Tirzepatide can't be supplied indefinitely without a clinical review. Before your pen runs out, we'll ask you to complete a short follow-up so a prescriber can check your progress, adjust your dose if needed and issue your next prescription, so there's no gap in treatment.
