Mounjaro 2.5mg is the licensed starting dose for adults beginning treatment. This page explains the current price for a single 2.5mg pen, why this dose is used at the start of treatment, and what to consider when comparing providers. Rather than making an unverified claim about being the "cheapest in the UK", we focus on the prices and information available at the time of writing.
Whether 2.5mg is suitable for you, and whether your dose should increase later, is a clinical decision made with your prescriber. Price should not be the only factor you consider when choosing your treatment.
Key things to know
- 2.5mg is the licensed starting dose for adults beginning Mounjaro treatment. It is not simply a lower cost alternative to the higher strengths.
- Pricing is shown in three tiers: a regular price, a current price with a discount applied, and a Future Orders price for repeat orders.
- Be cautious of claims that a provider is the "cheapest" in the UK, as prices can vary between pharmacies and can change over time.
- Be careful with claims about "MHRA approved processes" or supply chains that other providers supposedly do not have. Check what the claim actually means before making a decision.
- Always check the exact current price at checkout, as prices shown on different pages of a website may change or may not always match.
Why Everyone Starts at 2.5mg
2.5mg is the licensed starting dose for adults beginning Mounjaro treatment, regardless of the dose they may be prescribed later. It is used as the starting point before any increase is considered.
Because 2.5mg is the starting dose, the main SURMOUNT 1 trial results focus on the 5mg, 10mg and 15mg maintenance doses rather than 2.5mg. If you are looking at results from this study, it is important to remember that these figures relate to the maintenance doses used in the trial, not the initial 2.5mg dose.
Starting at a lower dose allows your prescriber to assess how you respond to Mounjaro before considering a dose increase. Gastrointestinal side effects such as nausea, diarrhoea and vomiting can occur with Mounjaro, particularly when starting treatment or increasing the dose.
What to Expect During Your First Weeks at 2.5mg
Mounjaro is normally started at 2.5mg once a week for the first four weeks before a possible increase to 5mg. Your prescriber will decide whether an increase is suitable based on your response and how well you tolerate the medicine.
Some people experience side effects such as nausea, diarrhoea, vomiting or reduced appetite during the early weeks of treatment. These effects can vary from person to person and may become less noticeable as treatment continues. If you experience severe or persistent side effects, contact your healthcare provider for advice.
You may not notice much change during the first week or two. This does not necessarily mean that the medicine is not working. Tirzepatide has a half life of around five days, and it can take several weeks for the level of medicine in your body to reach a steady state.
Mounjaro contains tirzepatide, which works on the GIP and GLP 1 hormone pathways. It can affect appetite and digestion and can also help regulate blood glucose levels. These effects may contribute to weight loss for some people when Mounjaro is used as part of an appropriate treatment plan.
Mounjaro treatment is generally used alongside a reduced calorie diet and increased physical activity. Your prescriber can give you advice on lifestyle changes that may support your treatment.
If you are concerned that 2.5mg is not having the expected effect, speak to your prescriber. Do not take an extra dose or change your treatment schedule without medical advice.

| Pricing tier | Price |

The price of a 2.5mg Mounjaro KwikPen can vary between UK providers. Some pharmacies may charge more than £200, while others may offer lower prices. This means it is worth comparing the total cost rather than relying on one advertised price.
The regular price is the reference price used to show the discount. The current price is the price available to a new customer at the time of purchase. The Future Orders price is the price shown for repeat orders.
Across the market, the price of a 4 week 2.5mg Mounjaro pen can vary. Some specialist weight management services may advertise prices around £120 per month, while providers such as The Care Pharmacy list £149.99 including a consultation. Prices can change, including following changes in manufacturer or wholesale pricing.
Mounjaro may also be available through the NHS in England for eligible patients who meet the relevant prescribing criteria. Where NHS prescription charges apply, the standard charge is £9.90 per prescription.
It is worth checking the price shown at checkout before placing an order. Other pages on this site have previously shown a different price for 2.5mg (£129.99 first order, £144.99 returning, against a £169.99 regular price) compared with the £174.99, £144.99 and £149.99 shown here, which are sourced from the live buy box. Always confirm the current price at checkout.
Why "Cheapest" and Supply Chain Claims Are Hard to Verify
You may see pharmacies describe themselves as the UK's cheapest Mounjaro provider. Some may also mention a particular supply chain or an "MHRA approved process". These claims should be considered carefully.
The MHRA regulates medicines and healthcare products in the UK. It does not mean that one pharmacy's internal supply process is automatically better than another simply because a provider uses the phrase "MHRA approved".
Supply chain claims can also be difficult to compare without clear evidence. Prices can vary between providers, and introductory discounts or voucher codes may affect the price you actually pay.
Be cautious with specific claims about unnamed "high street pharmacies" charging a particular amount, especially when there is no clear source for the comparison.
You can check whether a pharmacy is registered with the GPhC registered pharmacy by using the General Pharmaceutical Council's public register. You should also check that a suitable clinical consultation and prescription process are in place.
Independent price comparison websites may help when looking at Mounjaro prices. Comparing prices across UK pharmacies can help you understand the range available, but the lowest advertised price is not necessarily the only factor to consider.
Mounjaro is a prescription only medicine in the UK. If you are considering buying Mounjaro online, make sure you are using a legitimate pharmacy and that the required clinical assessment and prescribing process are followed.

The price shown increases with each strength. This reflects the different strengths of tirzepatide supplied in each pen and the pricing set by the provider.
Your dose may change as your prescriber reviews your treatment. This means your Mounjaro cost may also change over time. A lower starting dose does not necessarily mean that it will remain your long term dose.
What's Included in the Price
Every Mounjaro order includes your online clinical consultation with a UK registered prescriber, your prescription where treatment is approved, and dispensing through a GPhC registered pharmacy.
Mounjaro is a prescription only medicine in the UK, so the ordering process includes a clinical assessment before treatment can be supplied. The price covers the medicine and the services included by the provider, rather than the pen alone.
If you use private insurance or an employer health plan, prior authorisation may be required before Mounjaro treatment is covered. Standard approval is stated as taking around 3 working days, with a paid express option available for a faster turnaround.
Estimating Cost If You're Maintained at 2.5mg
Although 2.5mg is the starting dose, your prescriber may decide that continuing at this strength is appropriate in some circumstances. The suitable dose can vary from person to person.
At the Future Orders price of £149.99 per pen, 13 pens would cost approximately £1,949.87 over a year. This is only an example based on the listed price. Your actual cost may be different if the price changes or your prescribed dose changes.
Bundle Options for New Patients
Because 2.5mg is the starting dose, some providers offer bundles that combine it with higher strengths. These bundles may be presented as a convenient way to plan for possible dose changes.
However, your prescriber decides whether and when your dose should increase. Buying a bundle does not mean that you will automatically move to a higher strength.
If you are considering a bundle, check the exact products, strengths, terms and current price before ordering. You may also prefer to start with the initial 2.5mg treatment and discuss your next dose with your prescriber before committing to a larger order.
Getting Started with EverydayMeds
Treatment begins with a free online clinical consultation reviewed by our UK registered prescribing team. The prescriber will assess your medical history, check your eligibility and consider whether Mounjaro is suitable for you.
Where appropriate, this may include checking your age and BMI against the relevant prescribing criteria. Treatment is generally considered for adults aged 18 to 75 with a BMI of 30 or above, or a BMI of 27 or above with a weight related health condition such as high blood pressure or high cholesterol.
Mounjaro may be prescribed for weight management in eligible adults when the prescriber considers it appropriate. It is generally used alongside diet and physical activity as part of a wider weight management plan.
Treatment is dispensed by our GPhC registered pharmacy and supplied in line with the applicable UK requirements.
Mounjaro should not be used during pregnancy. If you are breastfeeding, planning a pregnancy or think you may be pregnant, speak to your healthcare provider before using Mounjaro.
Mounjaro may also affect how some oral contraceptives work, particularly after starting treatment and after dose increases. Discuss contraception with your prescriber so that they can advise you based on your circumstances.
