How Much Do You Pay for Mounjaro in the UK? (October 2026)

01 · The short answer

What do you pay for Mounjaro privately?

You pay for each Mounjaro pen as you order it. A pen holds four weekly doses, so one pen is roughly a month of treatment. The 2.5mg starting pen has a standard price of £169.99, which works out at £42.50 per week. Your first 2.5mg pen costs £129.99 with code FIRST40, because the new-customer discount is already included in that first-order figure.

Price rises with the dose. The 5mg pen is £218.99 (£54.75 per week), 7.5mg is £279.99, 10mg is £290.99, 12.5mg is £319.99 and 15mg is £329.99 (£82.50 per week). Every later order after your first is £25 off the standard price, applied automatically (code DOSE25).

Switching to us from another provider at a higher dose? Your first order at 15mg is £289.99, because the new-customer discount applies at any dose. The consultation is free and the price shown is the price paid, with no hidden fees. Stock is currently in stock across the range.

02 · Fair price

How much should you pay for Mounjaro?

A fair price is one you can compare like for like: same dose, same genuine pen, same prescriber review. Our price index of the UK pharmacies we track (checked 10 October 2026) shows how wide the range is.

Those gaps are large enough that checking two or three providers is worthwhile. Compare the dose you will actually be on, not just the starter pen, because a cheap first pen can be followed by dearer later ones. See our fuller guide on how much Mounjaro costs in the UK.

03 · Payment

How do you pay for Mounjaro?

Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full.

We accept Visa and Mastercard, Klarna and pay-monthly options, with no subscriptions. For the details, see our guides on paying with Klarna and paying monthly.

04 · Cost of titration

What the first year costs

Your costs depend on how quickly you move up the dose ladder and where you settle. Everyone starts on 2.5mg once a week. After at least 4 weeks the dose increases to 5mg, and can then step up by 2.5mg at a minimum of 4-week intervals (7.5mg, 10mg, 12.5mg) up to a maximum of 15mg weekly, depending on how you respond and tolerate it.¹ Many people settle at a maintenance dose of 5mg, 10mg or 15mg, and higher is not automatically better.

These are standard prices. A new customer's first order is £40 less, and every later order is £25 less, so the real total is lower. If you settle at 7.5mg, 10mg or 12.5mg, your monthly pen price is £279.99, £290.99 or £319.99 respectively.

Because your prescriber guides the pace, you may stay on a dose longer than the minimum. That means these figures are a planning guide, not a promise of how long each step lasts.

05 · NHS or private

Do you have to pay for Mounjaro, or is it on the NHS?

Mounjaro is available on the NHS, but access is being phased in over several years.⁶ NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition, and the NHS primary-care rollout began in June 2025 with the highest-need groups first (initially BMI 40+ with four or more qualifying conditions).⁴ Full rollout is expected to take years, which is why many people who meet the licensed criteria choose regulated private treatment rather than waiting.

So the honest answer is that it depends on whether you are in an NHS group that is currently being treated. Your GP can tell you where you stand locally. Our guide to what you pay for Mounjaro on the NHS goes through the detail.

If you are not yet reachable through the NHS, self-pay is the alternative. Choosing it is a personal decision about timing and budget, and you can still talk to your GP at any point. Private treatment does not stop you joining an NHS pathway later.

06 · Why prices differ

Why do Mounjaro prices differ between pharmacies?

Pharmacies buy at a list price set by the manufacturer, and Eli Lilly raised its UK list price for Mounjaro in 2025, with the largest rise on the highest dose.¹⁰ Pharmacy sell prices still vary because of confidential discounts, so what a pharmacy pays is not public, and you cannot work out its margin from the shelf price.

That is why the answer to "how much do pharmacies pay for Mounjaro" is not a single published figure. What you can compare is the price you are charged, per dose, and what comes with it. The price index is dated so you can see how current it is (10 October 2026).

When you compare, check the following rather than only the headline price:

• Whether the price is for the same strength of pen you will actually use.
• Whether a prescriber review is included and what happens if you are declined.
• Whether delivery is free and temperature-controlled.
• Whether the discount is for first orders only or continues on repeat orders.
• Whether the pharmacy is on the GPhC register and sources genuine pens.

07 · What is included

What does the price include?

Our price covers the pen itself and the clinical service around it. EverydayMeds is a GPhC-registered UK online pharmacy (registration GPhC 9012878), and you can check the entry on the GPhC register.¹² Mounjaro comes from official LillyDirect supply, direct from Eli Lilly's UK distribution, as genuine KwikPens.

• A free online consultation reviewed by a GPhC-registered prescriber, not a scoring script.
• Free next-day tracked delivery in discreet, temperature-controlled packaging, with same-day dispatch when you order by 3pm. Saturday delivery is £14.99.
• Needles, a sharps bin and injection guidance with every order.
• Ongoing monthly reviews, dose-titration and follow-up assessments by the prescribing team.
• The free GLPTrackr companion app for tracking your journey.

Repeat orders re-check suitability and there is no auto-shipping, so you never pay for a pen you did not choose to reorder. Support is available Monday to Friday, 9am to 5pm.

08 · Avoiding scams

How to avoid paying for fake Mounjaro

A very low price is a warning sign, not a bargain. Mounjaro is a prescription-only medicine, supplied only after an online consultation reviewed by a GPhC-registered prescriber. Anyone offering to supply without a consultation or prescription is not operating legitimately.

The MHRA publishes counterfeit medicine alerts and runs the Yellow Card scheme for reporting problems.⁷ Social media sellers, marketplaces and unregulated websites are common routes for counterfeit pens. Before you pay anywhere, confirm the seller on the GPhC register, and be wary of anyone who asks for payment by bank transfer to an individual.

If you notice a side effect after any purchase, you can report it through the Yellow Card scheme.¹⁹ Retail marketplaces such as Amazon are not a licensed route to a prescription weight-loss injection, and over-the-counter products are not equivalent to Mounjaro.

09 · Value for money

What do you get for what you pay?

Value depends on what treatment can realistically deliver alongside diet and activity. In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of their body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, compared with 3.1% with lifestyle changes alone.² These are trial averages; individual results vary, and treatment works alongside a reduced-calorie diet and increased physical activity, not instead of them.

Weight loss on Mounjaro is gradual by design. The first weeks on 2.5mg are an adjustment phase and losses are usually modest; most measurable progress builds from 5mg onward, month by month. Treatment response is reviewed by your prescriber, so you are not paying indefinitely for a dose that is not working for you.

Also consider the cost of stopping. Tirzepatide has a half-life of about five days, so after a final dose it takes roughly four to five weeks to clear the system.¹ Nothing needs doing while it clears, but plan how you will maintain habits once treatment ends.

10 · Ways to save

How to keep the cost down safely

The safe ways to spend less are the legitimate ones: use the discounts and avoid waste. A new customer's first order is £40 off with code FIRST40, and an automatic £25 reorder discount applies to every future order (code DOSE25).

Avoid waste too. Keep Mounjaro pens in a fridge at 2–8°C and never freeze them. Once in use, a pen can be kept out of the fridge at a temperature not above 30°C for up to 30 days after first use and must then be thrown away. Do not use a pen that has been above 30°C or has been frozen.¹³ If you want to spread payment rather than cut the total, see our page on paying for Mounjaro weekly.
