If you are looking to buy Mounjaro on a private prescription in the UK, you will usually start with an online consultation with a UK registered prescriber. If treatment is considered appropriate, it can then be prescribed and dispensed by a GPhC registered pharmacy and delivered in discreet, temperature controlled packaging.
Many people considering a private Mounjaro prescription also want to know whether they could access treatment through the NHS. This is particularly relevant if you are looking for weight management treatment but may not meet the current NHS eligibility requirements. Private treatment can offer another route, but it still requires a clinical assessment and prescribing decision.
It is also worth understanding the practical differences before you order. Private and NHS treatment have different eligibility requirements, costs and access routes. Below, we explain how private prescribing works, what you may pay, how the ordering process works and what to check before buying Mounjaro online.
Private Is Not the NHS Route With a Shorter Queue
This is an important distinction to understand.
NHS supply of tirzepatide for weight management began a phased rollout in March 2025, following NICE technology appraisal TA1026. However, NHS access is subject to specific eligibility criteria and local NHS pathways. These criteria are more restrictive than the licensed criteria for private prescribing, and access is being introduced in phases based on clinical need.
For NHS weight management treatment, eligibility can involve a higher BMI together with multiple weight related health conditions. The exact route can also depend on how services are organised in your area. Your GP or local NHS weight management service can advise whether you currently meet the requirements.
Private prescribing follows a different route. You still need to meet the relevant clinical criteria and complete an assessment, but you do not need to rely on NHS eligibility or local NHS commissioning arrangements. A UK registered prescriber will review your medical history, current medicines, weight and other relevant information before deciding whether Mounjaro is appropriate for you.
Choosing private treatment does not mean skipping the clinical checks. It simply means the prescription and supply are arranged privately rather than through the NHS.
| NHS route | Private route | |
|---|---|---|
| Eligibility | Much narrower than the licence during phased rollout, prioritised by clinical need | The licensed criteria |
| Cost to you | NHS prescription charge | Full price, from £129.99 |
| Access | Via GP or specialist weight management service, subject to local commissioning | Direct online consultation |
| Who prescribes | NHS clinician | UK-registered prescriber |
For some people, private prescribing may provide access where NHS treatment is not currently available through local pathways .
Check the NHS first anyway
If you think you may qualify for NHS treatment, it is worth asking your GP before committing to private treatment. The cost difference can be significant. Private Mounjaro treatment may cost around £1,900 to £3,200 a year depending on the strength and how long treatment continues, while NHS treatment is subject to the usual NHS prescription charges where applicable.
It costs nothing to ask your GP, and if you qualify for NHS treatment, this could make a substantial difference to your overall cost. Your GP can also explain whether you currently meet the NHS eligibility criteria and what local treatment options are available.
What a Private Prescription Actually Is
A private prescription is issued outside the NHS by a prescriber who is appropriately registered to prescribe in the UK. The same professional prescribing standards and clinical responsibilities apply. The main difference is that you access and pay for the treatment privately rather than through the NHS.
A private prescription is not a way to avoid a clinical assessment. A legitimate private service should assess whether treatment is suitable for you before prescribing. A prescriber may decide not to prescribe if Mounjaro is not clinically appropriate.
Your prescription is reviewed by a UK registered prescriber as part of our service.
How to Get a Private Mounjaro Injection Prescription
- Complete the free online consultation. You will be asked about your height and weight, medical history, current medicines, previous attempts at weight management and any relevant health conditions. Give complete and accurate information, including anything you are unsure about, so the prescriber has the information needed to assess your suitability.
- Prescriber review. Standard review takes place within 3 working days. An optional express review is available for £24.99, with a prescribing decision aimed for within 24 hours. Express review speeds up the prescribing decision, not the delivery. If you are prescribed Mounjaro, your treatment may also involve ongoing reviews of your progress, side effects and dose.
- Outcome. You may be approved, asked for more information or told that treatment is not suitable. This is a normal part of private prescribing. If treatment is not approved, you are not charged for medicine that is not supplied.
- Dispensing and delivery. If your prescription is approved, your medicine is dispensed by our GPhC registered UK pharmacy and sent using tracked, temperature controlled delivery. Mounjaro pens are supplied in discreet packaging, with delivery details confirmed during the ordering process.
Why your GP should still know
You do not need a GP referral to request a private prescription. However, it is still a good idea to tell your GP if you start Mounjaro privately.
Your GP has access to your wider medical record, while an online consultation relies on the information you provide. Keeping your GP informed can help ensure your medical records are up to date, particularly if you take other medicines or receive treatment for another condition.
Let your GP know that you have started Mounjaro privately so they are aware of your current treatment. This can also help avoid potential issues if you are prescribed other medicines or receive medical care in the future.

Does Private Health Insurance Cover Mounjaro?
Often, no. UK private medical insurance commonly focuses on treating acute or diagnosed medical conditions, and weight management medicines may be excluded from cover. Some corporate or premium policies may offer limited weight management support, but this is not something you should assume is included.
If you have private health insurance, check your own policy terms or speak to your insurer before budgeting for treatment. Cover varies between providers and policies, so your insurer is best placed to confirm whether Mounjaro is covered.
Paying for Private Treatment
Payment is taken through a secure checkout once your order has been approved. Klarna and Clearpay may be available if you want to spread the cost.
Spreading the cost does not reduce the overall price. Buy now, pay later options are a form of credit, so check the total amount you will pay and make sure the instalments fit comfortably within your budget. This is particularly important if you continue treatment, as higher strengths may cost more than the starting dose.
There is no minimum treatment term and no subscription. Repeat orders involve a further clinical check rather than automatic dispatch.
Making Sure It Is Genuine and Understanding the Side Effects of Mounjaro
If you are buying a prescription medicine privately, it is important to check that the provider is appropriately regulated. Taking a few minutes to check the pharmacy and prescribing process can help you avoid unregulated or potentially unsafe sources.
Check the GPhC register. The General Pharmaceutical Council maintains a public register of registered pharmacies and pharmacy professionals. Before ordering, check that the pharmacy can be verified on the register and that the details match the provider you are using.
Check that there is a proper clinical assessment. A legitimate prescribing service should ask about relevant information such as your medical history, current medicines, BMI and any conditions or circumstances that could affect whether Mounjaro is suitable. A prescriber should also be able to decide that treatment is not appropriate where necessary.
Check that it is the licensed product. There is currently no licensed generic tirzepatide in the UK. Mounjaro is the licensed brand made by Eli Lilly. The MHRA has issued warnings about falsified weight loss medicines being supplied outside the regulated supply chain, so be cautious about products from sources you cannot verify.
Check how it is delivered and stored. Unopened Mounjaro pens should be stored in a refrigerator at 2°C to 8°C. Follow the patient information leaflet for the full storage instructions. Once a pen is in use, it may be kept at room temperature for the period specified in the product information, provided the temperature does not exceed the stated limit. Suitable tracked and temperature controlled delivery can help protect the medicine during transit.
If you are offered tirzepatide without an appropriate clinical assessment, or by a provider that you cannot verify through the relevant regulatory register, take extra care before ordering.
One final point about the name: Mounjaro is sometimes misspelled as “Monjaro” in searches. The correct brand name is Mounjaro, made by Eli Lilly. Genuine UK packaging should identify the medicine accordingly. If the product or packaging looks different from what you were expecting, check with a pharmacist before using it.
Who Is Eligible
For weight management, the licensed criteria are a BMI of 30 or above, or 27 or above where a weight related health condition is present, such as high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease, prediabetes or type 2 diabetes.
Treatment may not be appropriate if you are pregnant, breastfeeding or trying to conceive, have a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2, have had pancreatitis, have certain digestive conditions, or are under 18. Your prescriber will also consider other aspects of your medical history before deciding whether treatment is suitable.
These are general criteria, not a self assessment. If Mounjaro is prescribed, it is taken once weekly according to the prescribing instructions and as part of an individual treatment plan. Your prescriber will assess whether this weight management treatment is appropriate for you based on your medical history, current health and treatment needs.
MHRA advice issued in June 2025 states that additional or non oral contraception should be used for four weeks after starting tirzepatide and for four weeks after each increase in strength, because slowed gastric emptying may affect the absorption of the oral contraceptive pill. If you use oral contraception, discuss this with your prescriber before starting or increasing your dose.

What Mounjaro Weight Loss Medication Is
Mounjaro is the brand name for tirzepatide, made by Eli Lilly and supplied in the KwikPen device. Tirzepatide acts on two hormone receptors called GIP and GLP 1, which are involved in appetite regulation and blood glucose control. GIP stands for glucose dependent insulinotropic polypeptide. Together, these pathways can affect appetite, feelings of fullness and blood glucose levels, as well as the rate at which the stomach empties.
Mounjaro is licensed in the UK for weight management alongside a reduced calorie diet and increased physical activity. It is also licensed separately for the treatment of type 2 diabetes. In clinical trials, people taking tirzepatide experienced significant average reductions in body weight, with results varying between individuals. In some studies, average weight reductions of up to 22.5% were reported over 72 weeks. These figures are study averages and should not be treated as a prediction of what any individual will achieve.
Mounjaro is taken once a week and follows a stepped dosing schedule. Treatment usually starts at 2.5mg once weekly, and the dose may be increased at intervals of at least four weeks if your prescriber considers this appropriate. The dose is based on factors such as how you are responding to treatment and how well you tolerate it. Not everyone needs the maximum dose.
Common side effects include nausea, diarrhoea and constipation. These effects may improve as your body adjusts to treatment, although this varies between individuals. If you experience severe or persistent symptoms, speak to your prescriber or another healthcare professional. Seek urgent medical advice if you develop severe abdominal pain, persistent vomiting, signs of significant dehydration or other serious symptoms.
Injection site reactions, such as redness, rash or swelling, can also occur. Read the Patient Information Leaflet supplied with your medicine before using Mounjaro and follow the instructions provided.
NICE TA1026 includes a review point that is useful to understand before starting private treatment. If less than 5 per cent of initial body weight has been lost after six months on the highest tolerated dose, the clinician should decide whether continuing treatment is appropriate, taking the benefits and risks into account. Private treatment is also reviewed over time rather than being an automatic long term commitment.
Alcohol can contribute additional calories and may make weight management more difficult for some people. If you drink alcohol while using Mounjaro, discuss this with your prescriber if you have any concerns.
