Mounjaro in Preston: NHS Access, Private Cost & 2026 Price Guide
Mounjaro has become one of the most talked-about weight-loss treatments in the UK. If you are considering it, you are probably weighing up three things: what it costs privately in 2026, whether you can get it on the NHS, and where to obtain it safely and legitimately in Preston.
In short: private Mounjaro treatment currently costs roughly £120 to £340 per month, varying by dose and provider. NHS access is being introduced in phases on a clinical priority basis. Mounjaro is a prescription-only medicine, so it must be supplied only after a proper medical assessment by a qualified prescriber.

What Is Mounjaro?
Mounjaro is the brand name for tirzepatide, a once-weekly injectable medicine. What distinguishes it from other weight-loss injections:
- It is dual-action, targeting both GLP-1 and GIP receptors, whereas Wegovy and Ozempic target GLP-1 only.
- It improves insulin sensitivity, reduces appetite and slows digestion.
- In the SURMOUNT-5 trial it produced greater average weight loss than GLP-1-only medicines.
Mounjaro vs Wegovy vs Ozempic
| Feature | Mounjaro | Wegovy | Ozempic |
|---|---|---|---|
| Ingredient | Tirzepatide | Semaglutide | Semaglutide |
| Mechanism | GIP + GLP-1 | GLP-1 | GLP-1 |
| Licensed for | Weight management & type 2 diabetes | Weight management | Type 2 diabetes |
| Dosing | Weekly injection | Weekly injection | Weekly injection |
| UK access | NHS (phased) & private | NHS (restricted) & private | NHS (diabetes only) & private |
Mounjaro’s 2025-26 Price Rise: What Changed
If Mounjaro seems more expensive than it used to be, you are not imagining it. In August 2025 Eli Lilly announced a rise of up to 170% in UK wholesale prices to bring them closer to European markets. It took effect in September 2025, and the wholesale price of the highest dose rose from £122 to £330 per pen.
Now What Does This Mean for Private Patients?
lower doses rose by roughly 30% to 100%, the steepest rise landed on the highest maintenance dose, and patients on higher doses have seen annual costs increase by over £2,500.
For NHS patients: nothing changed. A separate pricing agreement applies, so eligible NHS patients still pay the standard prescription charge in England, and prescriptions are free in Scotland and Wales.
Indicative Private Mounjaro Costs (2026)
| Dose | Typical monthly cost |
|---|---|
| 2.5 mg (starter) | £120 – £220 |
| 5 mg | £149 – £249 |
| 7.5 mg – 12.5 mg | £220 – £300 |
| 15 mg (highest) | £300 – £340 |
Prices vary between providers and by exact dose. Always check your total monthly cost before committing.
Can I Get Mounjaro on the NHS?
Yes, but access is limited and being introduced gradually. Even if you meet the wider NICE criteria, it is not guaranteed your GP can prescribe it immediately.
Who Can Get Mounjaro on the NHS in 2026?
NHS England is currently offering it on a clinical priority basis, starting with those at highest risk from weight-related disease. Under the 2026/27 implementation guidance, priority groups include people with:
- A BMI of 35 to 39.9 kg/m², and
- At least four qualifying weight-related conditions, such as high blood pressure, type 2 diabetes, abnormal cholesterol or obstructive sleep apnoea.
Eligibility is not based on BMI alone. Activity levels, ethnic background, existing conditions and overall health are all considered.
Who Qualifies for Mounjaro?
Private eligibility criteria are not identical to the NHS. A private GP may assess your current weight and BMI, medical history, current medicines, existing weight-related conditions, previous weight-loss attempts, your goals and lifestyle, and any safety concerns.
You May Be Considered for Mounjaro If You:
You may be considered if you are an adult seeking prescription weight management, have a BMI of 35 kg/m² or above with at least one weight-related condition (or a lower BMI threshold where appropriate for your ethnic background), and have been assessed by a qualified clinician who judges tirzepatide appropriate for you.
Important: meeting any of these criteria does not automatically make you eligible. Treatment is only appropriate when prescribed after a full assessment.
How Much Weight Can You Lose With Mounjaro?
Used alongside a calorie deficit, physical activity and lifestyle change, research suggests average weight loss of around 15% to 21%, with higher doses generally producing greater results and outcomes typically exceeding semaglutide alone. Results vary considerably from person to person.
Do I Need a Prescription for Mounjaro?
Yes. Mounjaro is a prescription-only medicine, supplied only after a thorough assessment by a qualified prescriber. It cannot be bought over the counter.
If you are searching for “Mounjaro near me”, “Mounjaro clinic” or “can I get Mounjaro without a doctor referral”, check the legitimacy of the provider and their pharmacy arrangements rather than deciding on price alone. Any service willing to supply it without a proper medical assessment should be treated as a warning sign.
Side Effects and Safety
Like any prescription medicine, Mounjaro has side effects. Common ones include diarrhoea, constipation, nausea and vomiting, abdominal discomfort or pain, bloating, delayed stomach emptying and indigestion.
Less common but serious: severe or persistent abdominal pain (which may indicate pancreatitis), allergic reactions, dehydration, gallbladder problems, and changes in blood glucose. Seek prompt medical attention if you experience these.
Who should not take Mounjaro?
Tell your GP during your consultation if you have a known allergy to tirzepatide, a history of pancreatic disease, take medicines that may interact, are pregnant or breastfeeding, have surgery or anaesthesia planned, or have significant gastrointestinal problems.
Getting Mounjaro Privately at My Private Clinic, Preston
Every private prescription is overseen by Dr Faizal Secretary, so treatment is appropriate, properly monitored and safe.
What happens during your consultation:
- Initial assessment — your BMI and medical history, existing conditions, current medicines, previous weight-loss attempts and overall suitability for tirzepatide.
- Private blood tests — thyroid, kidney and liver function and other tests where clinically appropriate.
- Clinical review — whether an injection, another medicine, or a different approach is right for you.
- Prescription and guidance — dosing, how to use it, realistic expectations, and a specialist referral where needed.
- Ongoing monitoring — routine follow-ups to track progress and tolerance.
If you are suitable, your GP will guide you through the process and next steps, advise on the lifestyle changes that make treatment work, show you how to use the medication correctly, and monitor your symptoms and progress so weight loss stays safe and steady.
Why choose a private Mounjaro consultation?
A private consultation lets you discuss your options and treatment plan in detail after a full clinical review, without waiting for a place on an NHS pathway. You get the time to make the right decision for your own goals rather than a rushed yes or no.
Mounjaro Cost at My Private Clinic, Preston
Mounjaro is not prescribed automatically. The initial medical weight management consultation is £99, which includes a face-to-face assessment and a decision on whether Mounjaro is the right option for you. Any medicine cost is discussed clearly before you start. See the pricing page for the full fee list.
Other Weight Loss Options at My Private Clinic
Weight-loss injections are not right for everyone. Depending on your assessment, your GP may suggest:
- GP-led weight management with ongoing support.
- Health MOT to identify undiagnosed conditions.
- Private blood tests to check for metabolic factors affecting weight.
- Thyroid function tests, since thyroid problems can cause weight change.
- Diabetes (HbA1c) screening where appropriate.
- Blood pressure check and ECG if a heart assessment is appropriate.
- Well man and well woman checks for a broader review.
- Female hormone tests to assess PCOS, where hormonal imbalance contributes to central weight gain.
Frequently Asked Questions About Mounjaro
What happens if I miss a Mounjaro dose?
Take it as soon as possible within 4 days (96 hours). If more than 4 days have passed, skip it and take your next dose on the usual day. Never take two doses to make up for a missed one.
What happens when you stop Mounjaro?
Speak to your prescriber first. Stopping can affect appetite and weight, and people with type 2 diabetes may see changes in blood glucose control.
Can I switch from Wegovy to Mounjaro?
Some people can, but only under a prescriber’s guidance, taking into account your previous medicine, dose, response and medical history.
Can I drink alcohol while taking Mounjaro?
There is no requirement to avoid it completely, but alcohol may worsen gastrointestinal symptoms and contribute to dehydration.
Can I exercise while taking Mounjaro?
Yes. Regular activity is encouraged alongside treatment, appropriate to your fitness level and any existing conditions.
How long does it take to work?
Some people notice reduced appetite early, but weight loss develops gradually. Treatment starts low and may increase every four weeks where appropriate.
How long can I stay on Mounjaro?
There is no fixed duration. NICE recommends reassessing if less than 5% of initial body weight has been lost after six months on the highest tolerated dose.
Can I take Mounjaro with other medicines?
Tell your prescriber about everything you take. Tirzepatide can affect absorption of some oral medicines, and those on insulin or sulfonylureas may have a higher risk of low blood sugar.
Can I take Mounjaro if I have type 2 diabetes?
Yes. Tirzepatide is also licensed for type 2 diabetes. Your prescriber will consider your existing diabetes treatment and glucose control.
Can Mounjaro affect the contraceptive pill?
It can affect absorption of oral contraceptives, particularly when starting and after dose increases. UK product information advises considering a non-oral method, or a barrier method for 4 weeks after starting and after each increase.
Can I take Mounjaro during pregnancy?
No. It should not be used in pregnancy, and UK product information recommends stopping at least one month before a planned pregnancy.
Do I need blood tests before starting?
Not always. Your clinician decides based on your medical history, conditions, medicines and overall health.
Can I take Mounjaro long term?
It may be used as part of longer-term weight management where your prescriber judges that the benefits continue to outweigh the risks. Your progress, side effects and ongoing suitability should be reviewed regularly.
