Mounjaro Price in the UK: Cost by Dose and Prescription

The Mounjaro price in the UK depends on the dose, provider and services included. A private four-week supply currently starts at around £143 with Apomeds, while higher-strength pens can cost more than £330 elsewhere.

Mounjaro is a prescription only medicine containing the active ingredient tirzepatide. This weekly injection can support weight loss alongside a reduced calorie diet, physical activity and healthy lifestyle changes. [1, 2]

This guide covers Mounjaro cost by dose, private prescription fees, NHS access and how to compare UK pharmacies safely during your weight loss journey.

How much does Mounjaro cost by dose?

Each Mounjaro pen contains four weekly doses, so one pen usually covers four weeks. The starting dose is 2.5 mg once weekly. If appropriate, a healthcare professional may increase the dose of Mounjaro by 2.5 mg after at least four weeks on your current Mounjaro dose. [2]

The Apomeds Mounjaro price shown below was checked on 19 July 2026:

Dose of Mounjaro	Treatment stage	Apomeds price per KwikPen	Approximate weekly cost
2.5 mg	Starting dose	£142.99	£35.75
5 mg	Maintenance dose	£159.53	£39.88
7.5 mg	Dose-escalation step	£216.76	£54.19
10 mg	Maintenance dose	£243.09	£60.77
12.5 mg	Dose-escalation step	£273.79	£68.45
15 mg	Maximum maintenance dose	£283.79	£70.95

The displayed prices include the medication, delivery and Apo Global platform fee. A doctor’s fee may be charged separately where applicable. [1]

Higher strengths usually cost more, but the highest dose is not automatically the most appropriate option for every patient. Approved maintenance doses are 5 mg, 10 mg and 15 mg. A prescriber may keep you on a lower maintenance dose if it supports weight loss with manageable side effects. [2]

A Mounjaro price comparison UK search may show introductory offers or first-order discounts. Check whether the Mounjaro cost applies only to an initial order and whether consultation, delivery, needles and clinical support are included.

Where can you buy Mounjaro weight loss injections?

You can obtain Mounjaro through regulated high-street pharmacies, specialist online pharmacies or NHS services if you meet the relevant criteria. It is a prescription only medicine and cannot legally be bought over the counter. [2]

Current listed prices show why a Mounjaro price comparison UK review can be useful:

Provider	2.5 mg	15 mg
Apomeds	£142.99	£283.79
Asda Online Doctor	£148.97	£298.97
Pharmacy2U	£169.99	£299.99
Boots Online Doctor	£179	£339
Superdrug Online Doctor	£179	£339

Prices checked on 19 July 2026. Provider prices and included services may change.

Among the providers checked, standard four-week prices ranged from £142.99 to £339, depending on the dose and provider.

Some older comparisons quote £120 to £340 per month or suggest the 2.5 mg dose can be found for around £120. However, those figures do not reflect the current standard prices verified across major providers today.

The largest like-for-like difference in this table was £55.21. Prices therefore varied meaningfully between UK pharmacies, although the difference did not reach £80 to £100 for the same dose in this comparison.

A useful Mounjaro price comparison should consider the complete weight loss package, including the assessment, delivery and follow-up support, rather than only the first price displayed.

Eligible adults can buy Mounjaro online after an appropriate medical review.

What does the Mounjaro price include?

A private Mounjaro price may include more than the prescription only medicine itself. Depending on the provider, the package can cover:

• one Mounjaro pen containing four weekly injections;
• Mounjaro injection instructions;
• private prescription assessment or consultation;
• needles and sometimes a sharps container;
• temperature-controlled delivery;
• dose reviews and access to a healthcare professional;
• healthy diet, activity or behavioural support.

At Apomeds, the Mounjaro price includes the medicine, delivery and platform fee but excludes a doctor’s fee where one applies. [1] Other providers may bundle the private prescription and follow-up support into a single charge.

Storage and delivery also matter. Store Mounjaro at 2°C to 8°C before use and do not freeze it. After first use, store Mounjaro below 30°C for up to 30 days and protect the Mounjaro pen from excessive heat. [2, 4]

How much does Mounjaro cost over a full course of treatment?

There is no predefined treatment duration. Some people continue using it for months or longer while the medicine remains effective, safe and clinically appropriate.

Your Mounjaro cost in the UK depends on how quickly the dose rises and which maintenance dose you use. Using current Apomeds prices:

• Progressing through all six strengths at four-week intervals would cost about £1,319.95 over 24 weeks.
• Using 2.5 mg for four weeks and 5 mg for the remaining 44 weeks would cost about £1,897.82 over 48 weeks.
• Progressing to 10 mg and then remaining there would cost about £2,707.09 over 48 weeks.
• Progressing through every strength and using 15 mg for the final 24 weeks would cost about £3,022.69 over 48 weeks.

These are illustrations rather than personal forecasts. You may remain on one dose for longer, stop treatment, switch weight loss medication or never need the highest dose. A lower strength may reduce the Mounjaro cost, but clinical response and tolerability matter more than price alone.

In SURMOUNT-1, average weight loss at 72 weeks with the 10 mg dose was 19.5% under the treatment-regimen analysis and 21.4% under the efficacy estimand. With 15 mg, the corresponding average reductions were 20.9% and 22.5%. [8, 17]

The efficacy estimand assessed the expected effect if participants had remained on their assigned treatment, while the treatment-regimen analysis also accounted for treatment discontinuation. These figures should therefore not be treated as guaranteed personal outcomes.

Tirzepatide commonly reduces appetite, although the onset and degree of this effect vary between individuals [2]. The available evidence does not establish losing 5% of body weight within 4 to 8 weeks as a standard or guaranteed result. Starting weight, calorie intake, dose, adherence and other factors can all affect progress, which may eventually slow or reach a weight loss plateau.

The 21.4% and 22.5% figures come from the SURMOUNT-1 efficacy estimand, while UK product information reports reduced hunger from week one.

Can you get Mounjaro through NHS Weight Management Services?

Mounjaro can be prescribed on the NHS for type 2 diabetes under separate criteria. NHS access for weight loss treatment is also available, but primary-care access is being phased out and remains more limited than private access.

In specialist weight management services, NICE recommends tirzepatide for eligible adults with an initial BMI of at least 35 kg/m² and at least one weight related health condition. Lower BMI thresholds usually apply to people from certain ethnic backgrounds.

For primary care in England, the prioritised groups for 2026/27 include:

• Cohort I: BMI of at least 40 plus four or more qualifying comorbidities.
• Cohort II: BMI from 35 to 39.9 plus four or more qualifying comorbidities.

The qualifying conditions are hypertension, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease and type 2 diabetes. For primary-care access during 2026/27, people in both Cohort I and Cohort II must have at least four comorbidities from this NHS list.

Cohort I was prioritised first during 2025/26, and Cohort II was added for 2026/27. Local NHS services determine how eligible patients are identified and contacted, which may involve using GP records and established local pathways rather than open self-referral.

The rollout is planned over a maximum of 12 years. Meeting the eligibility criteria does not guarantee immediate treatment because local capacity, commissioning and access arrangements vary. NHS prescribing should also include nutritional, physical activity, and behavioural support. [5]

Readers may also encounter US information about insurance coverage. In the United States, some health plans require prior authorisation before covering Mounjaro for type 2 diabetes. This is separate from the UK NHS eligibility and commissioning process. [16]

NHS England confirms that year two includes Cohorts I and II, both requiring four qualifying comorbidities, while Lilly’s US guidance explains the separate prior-authorisation process.

How to get a Mounjaro prescription in the UK

A healthcare professional must assess whether Mounjaro for weight loss is suitable for you and whether this weight loss medication supports safe, sustainable weight loss.

The assessment should consider BMI, starting body weight, weight related health conditions, medical history, current medicines, previous attempts at losing weight and any previous weight gain.

Through your GP or a specialist

Your GP may assess whether you meet a primary-care pathway or refer you to a specialist service. Access depends on local commissioning, capacity and the current NHS cohort.

Mounjaro tirzepatide may also be prescribed for type 2 diabetes under separate NICE guidance. If you use insulin or a sulfonylurea, the prescriber may need to reduce its dose because combining it with tirzepatide can increase the risk of low blood sugar. [2, 11]

Other diabetes medications should be reviewed as part of your wider health background. Changes in blood sugar and side effects may also affect how your prescription medication is managed.

Through an online provider

A regulated online provider can issue a private prescription after completing the checks needed for safe prescribing. You may need to complete a medical questionnaire and provide evidence of identity, current body weight or earlier weight loss medication.

The provider should assess your medical history, current medicines and side effects rather than simply supply your requested Mounjaro dosage. Private treatment does not use the phased NHS eligibility route, but approval is not guaranteed, and you pay the full Mounjaro price yourself.

Before choosing a provider, compare the Mounjaro price, clinical support, delivery arrangements and dose-review process. The cheapest weight loss medication may not provide the most suitable service, so compare UK pharmacies carefully.

Buying Mounjaro in the UK: how to do it safely online

Buying weight loss injections and other weight loss medication online can be convenient, but the provider and dispensing pharmacy must be legitimate. Mounjaro should only be supplied after a proper clinical assessment.

Is the Mounjaro pen safe to buy online in the UK?

It can be safe when a regulated pharmacy dispenses the medicine after an appropriately registered prescriber approves treatment.

For pharmacies based in England, Scotland or Wales, check the General Pharmaceutical Council register. Pharmacies in Northern Ireland should appear on the Pharmaceutical Society of Northern Ireland register. [10, 12]

A legitimate service should:

• require a prescription or medical consultation;
• identify the pharmacy and prescriber;
• verify your BMI, starting weight and medical history;
• explain how to inject Mounjaro and use the Mounjaro pen;
• provide storage advice and information about side effects;
• offer access to a clinician or prescriber.

The Mounjaro injection is used once weekly. Before the first injection, read the pen instructions and inject Mounjaro only as directed.

If you have a missed dose, take it within 96 hours. If more than four days have passed, skip it and take the next dose on the usual day. When changing the injection day, leave at least 72 hours between doses.

In pooled weight-management clinical trials, gastrointestinal disorders affected approximately 56% of people treated with tirzepatide. Common side effects included nausea, diarrhoea, vomiting and constipation, while injection site reactions can include redness, itching or swelling.

Hair loss was reported in 4.9% of people treated with tirzepatide, compared with 1.0% of those receiving placebo. Most reported cases were mild, and hair loss generally resolved over time. This verified figure is lower than the “up to 10%” estimate sometimes quoted online.

Digestive side effects are often most noticeable during dose escalation and generally decrease over time. Most do not follow a fixed timetable, so it would be misleading to promise that they will resolve within a few weeks. Contact your prescriber if symptoms remain troublesome, persist or become worse after a dose increase.

The risk of low blood sugar increases when Mounjaro is used with together with insulin or a sulfonylurea. Signs may include sweating, shakiness, hunger or confusion. Seek urgent medical advice for severe abdominal pain spreading to the back, which can indicate pancreatitis. [2]

Warning signs of fake or unsafe Mounjaro sellers

Avoid sellers that:

• offer Mounjaro without a private prescription or consultation;
• let you choose any dose without checking your current Mounjaro dose;
• do not verify medical or weight information;
• have no checkable registration with the relevant UK pharmacies regulator;
• sell loose, damaged or unlabelled pens;
• claim that “generic Mounjaro” is an approved equivalent;
• Guarantee losing weight, or say Mounjaro burns fat directly.

Does Mounjaro burn fat? No, not directly. Its active ingredient affects appetite and blood sugar signalling, which may help some people reduce calorie intake as part of a broader weight loss plan.

In February 2026, the MHRA warned about falsified 15 mg pens labelled with batch D873576 that had been supplied through one UK online pharmacy. The pens were not considered safe to use. [6]

A suspiciously low Mounjaro price should be treated with caution, particularly if the seller is not properly regulated or dies not provide an appropriate clinical assessment. If the packaging or pen looks unusual, do not inject Mounjaro or try to extract a final dose.

How does Mounjaro compare in price with alternative weight loss treatments?

Price is only one part of choosing the best weight loss treatment. The active ingredient, dosing schedule, likely benefit, side effects, contraindications and available clinical support also matter.

Other weight loss injections may cost less, but they do not work in exactly the same way as Mounjaro. A healthcare professional can help you compare weight loss medicine options based on your health and treatment goals.

Wegovy (semaglutide)

Wegovy contains the active ingredient semaglutide and is a weekly injection. It acts on GLP-1 receptors, while Mounjaro tirzepatide acts on both GLP-1 and glucose dependent insulinotropic polypeptide receptors. [2, 7]

Wegovy can cost less than higher Mounjaro doses. Pharmacy2U currently lists Wegovy from £99.99 and Mounjaro from £169.99. [3]

In the head-to-head SURMOUNT-5 trial, Mounjaro produced greater average weight loss than Wegovy at 72 weeks. Average body weight fell by 20.2% with tirzepatide compared with 13.7% with semaglutide. [8]

Mounjaro was therefore more effective for average weight reduction in this particular clinical trial. However, that does not mean it is the most suitable treatment for every patient. Medical history, contraindications, side effects, affordability, availability and individual response should all influence the choice of weight loss therapy.

Saxenda (liraglutide)

Saxenda contains the active ingredient liraglutide and is injected daily rather than weekly. Its dose increases gradually to a maintenance dose of 3 mg per day. [9]

Availability of branded Saxenda is currently limited. Some providers instead offer liraglutide alternatives such as Nevolat; Asda currently lists Nevolat while describing Saxenda as long-term out of stock. [13]

A clinician can compare liraglutide, Wegovy, Mounjaro and weight loss pills. The right option depends on safety, effectiveness, side effects, cost and whether it fits alongside a balanced diet.

FAQs

Below, we answer common questions about Mounjaro prices, weekly treatment costs and possible future price changes in the UK. Keep in mind that prices can vary by dose, pharmacy and provider fees

Is Mounjaro cheaper than Ozempic?

Not necessarily. Prices depend on the dose and the pharmacy. Ozempic is licensed for treating type 2 diabetes rather than for obesity treatment in the UK, so it should not be chosen simply because its price appears lower. [14]

Is there a generic version of Mounjaro?

No licensed generic tirzepatide equivalent is currently listed for UK use. Mounjaro is the available branded tirzepatide medicine. Avoid sellers offering unlicensed “generic” versions without a prescription. [15]

How much does Mounjaro cost per week?

At current Apomeds prices, the approximate weekly Mounjaro cost ranges from £35.75 for 2.5 mg to £70.95 for the maximum maintenance dose. A separate doctor’s fee may apply.

What happens to the price if I lower my dose?

A lower dose usually costs less, but do not change treatment solely to reduce the Mounjaro price. A lower dose may affect appetite, blood sugar and weight loss progress.

Will Mounjaro prices come down?

Prices may change as supply, competition and available weight loss medicine options change, but reductions cannot be guaranteed.

Eli Lilly increased the UK list price from 1 September 2025, with the largest increases affecting higher strengths. [10] There is no confirmed equivalent September 2026 increase at the time of writing.
