Two questions often come up when people search for Mounjaro in the UK: How much does it cost, and how can I check that the pharmacy is legitimate?
At EveryDayMeds, eligible new customers can currently receive £40 off their first Mounjaro order. Eligible returning customers can currently receive £25 off subsequent orders. You can find more information about these offers on our Mounjaro discount code guide page.
The second question is just as important as the price. The MHRA has issued warnings about falsified and unlicensed weight loss medicines, including products sold outside the regulated UK supply chain. This is why it is important to check who you are buying from and whether the medicine is being supplied through a regulated pharmacy.
If you are looking for prescription-only Mounjaro for weight management, using a regulated UK pharmacy can give you greater confidence that the appropriate clinical assessment, prescription, dispensing, and supply processes are in place.
This page explains the Mounjaro KwikPen price list, why prices can differ between UK pharmacies, and what to check before ordering online. It also explains the clinical assessment and prescription process, how to check a pharmacy's registration, how Mounjaro is supplied and stored, and where first order discounts may apply.
What the Mounjaro KwikPen Weight Loss Injection Is
Mounjaro is the brand name for tirzepatide, manufactured by Eli Lilly. The KwikPen is a multi dose pen used to administer Mounjaro.
Key characteristics:
- Each pen contains four doses of the same strength, taken once weekly, so one pen is intended to provide four weeks of treatment when used as prescribed
- Mounjaro KwikPen is available in six strengths: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg, and 15mg
- It is a prescription only medicine and should be stored according to the manufacturer's instructions
- Mounjaro is injected under the skin. The patient information leaflet provides instructions on how to use the pen
The strength you are prescribed, including whether your dose should change during treatment, is a clinical decision made by your prescriber. It should not be chosen based on price or availability.

Why Mounjaro Prices Vary Between UK Pharmacies
The price of Mounjaro can vary between UK providers, even when they supply the same licensed product. There are several reasons for this.
Strength. Higher strengths generally cost more. If you see a particularly low starting price, check which strength it applies to. It may be the 2.5mg starting strength. Comparing the same strength makes it easier to understand the real difference between providers.
What is included. Some pharmacies charge separately for services such as the clinical assessment, prescription, delivery, or needles, while others include these in the advertised price. Always check the final amount you will pay rather than comparing the medicine price alone.
Subscription structures. Some providers may offer a lower introductory price as part of a subscription or ongoing arrangement. This can work differently from a one off purchase, so check the terms before ordering.
Availability. The availability of individual strengths can change over time. Prices and offers may also change, so it is worth checking the current price before placing an order.
Whether it is the licensed product. This is particularly important. Compounded tirzepatide, unlicensed imports, and falsified products are not the same as licensed Mounjaro supplied through the regulated UK medicines supply chain.
Quick check: Compare the total cost of your first 12 weeks, including the strength you may be prescribed and any additional fees. This gives you a more useful comparison than looking at a single headline price.
How to Verify a UK Online Pharmacy
Checking an online pharmacy before you order can help you make a more informed decision. You can verify several details yourself before sharing your medical information or making a payment.
1. Check the GPhC register. The General Pharmaceutical Council maintains a public register of registered pharmacies and pharmacy professionals. A registered online pharmacy should provide details that allow you to check its registration. If you cannot find the pharmacy on the register, do not proceed until you have confirmed its status.
2. Check the pharmacy premises. A registered pharmacy should operate from registered premises. Our pharmacy operates from licensed premises in Leicester, and the relevant company details are provided on the website.
3. Check there is a genuine clinical assessment. A legitimate provider should ask relevant questions about your medical history, current medicines, BMI, and other factors that may affect whether Mounjaro is suitable for you. A prescriber may decide not to supply treatment if it is not clinically appropriate.
4. Check who makes the prescribing decision. The prescribing decision should be made by an appropriately qualified prescriber who is registered with the relevant UK professional regulator. If a website gives little information about who is responsible for prescribing, consider checking this before ordering.
5. Check that you are receiving the licensed product. Mounjaro is manufactured by Eli Lilly. The product supplied in the UK should come in the appropriate manufacturer packaging with the relevant patient information leaflet. If a product is unbranded, does not appear to be licensed Mounjaro, or has unclear labelling, take extra care and ask the pharmacy for clarification.
6. Check how the medicine is delivered. Mounjaro is temperature sensitive and needs to be stored according to the manufacturer's instructions. Ask the pharmacy how the medicine is packaged and transported, particularly if you are ordering online.
Why This Matters for Tirzepatide
The MHRA has issued warnings about falsified and unlicensed weight loss medicines being sold in the UK outside the regulated medicines supply chain. Some falsified products may contain the wrong ingredients or incorrect amounts of active ingredients, which can pose serious health risks.
Buying Mounjaro without an appropriate prescription or clinical assessment is not simply a cheaper way to access treatment. It means you may not receive the clinical checks that help determine whether the medicine is suitable for you, and there may be no reliable assurance about the product's source or contents.
If you are offered tirzepatide without a clinical assessment, by an unregistered seller, or at a price that seems unusually low, take extra care. Check the pharmacy's registration and ask questions about the product before providing payment or personal information.
Paying for Treatment
Standard card payments are accepted through the secure checkout, and payment is taken once your order is confirmed.
There is no minimum treatment term or obligation to continue. Repeat orders require a further clinical check rather than being dispatched automatically.
Getting a Mounjaro Prescription Online
- Complete the free online consultation, which covers your medical history, current medicines, height, weight, and Body Mass Index.
- Prescriber review is typically completed within 3 working days, with express review potentially available within 24 hours. These are review timeframes and do not guarantee that treatment will be approved.
- Dispensing by the GPhC registered pharmacy if your prescription is approved.
- Free tracked delivery in plain, insulated packaging.
To request Mounjaro online, you need to complete a clinical assessment and receive approval from a qualified healthcare professional before prescription only treatment can be supplied.
Your prescriber may approve treatment, ask follow up questions, or decide that Mounjaro is not suitable for you. Not prescribing treatment can be an appropriate clinical decision where the medicine is not considered suitable. If the medicine is not supplied, you are not charged for it.
Who Mounjaro Is Licensed For
For weight management, the licensed criteria generally include a BMI of 30 or above, or a BMI of 27 or above where at least one weight related health condition is present. Examples include high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease, prediabetes, or type 2 diabetes.
Mounjaro may not be suitable for everyone. Your prescriber will consider your medical history and other factors, including pregnancy, breastfeeding, plans to become pregnant, previous pancreatitis, certain digestive conditions, and any allergies to tirzepatide or other ingredients in Mounjaro. Certain medical histories, including a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2, may also affect whether treatment is appropriate.
Mounjaro is not licensed for weight management in people under 18.
These are general criteria and should not be used as a self assessment tool. Meeting the BMI criteria does not automatically mean that you will be prescribed Mounjaro. A prescriber needs to assess your individual circumstances before deciding whether treatment is appropriate.
Mounjaro contains tirzepatide and is used once a week for weight management alongside a reduced calorie diet and increased physical activity. Tirzepatide acts on GIP and GLP 1 receptors, which are involved in appetite regulation and blood glucose control. Mounjaro is administered as a subcutaneous injection. The patient information leaflet provides instructions on how and where to use the pen.
NICE technology appraisal TA1026 recommends tirzepatide as an option for managing overweight and obesity in eligible adults alongside diet and increased physical activity. NHS access for weight management began with a phased rollout in March 2025, with eligibility being narrower than the licensed prescribing criteria.
If you think you may qualify for NHS treatment, speak to your GP. They can explain the current NHS eligibility requirements and local access arrangements.

Storage and Handling
- Unopened Mounjaro pen devices should be stored in a refrigerator according to the manufacturer's instructions
- Once in use, a pen may be kept at room temperature for the limited period stated in the patient information leaflet
- Mounjaro can be used at any time of day, but it should be taken on the same day each week where possible
- The weekly injection is given under the skin of the abdomen, thigh, or upper arm
- Do not use a pen if it has been frozen. Check the patient information leaflet for the full storage and handling instructions
- Keep pens in their original carton and protect them from light
- Used needles should be disposed of in a suitable sharps bin and not placed in household waste
If your delivery is delayed and you are unsure whether the required temperature was maintained, contact the pharmacy before using the pen. The pharmacy can advise you on what to do.
