If you have searched for "5ml Mounjaro", it is worth clearing up a common mix up first: Mounjaro is measured in milligrams (mg), not millilitres (ml). The 5mg strength refers to the amount of active ingredient, tirzepatide, in the dose, not a volume measurement. So, "5mg Mounjaro" is the correct way to describe this dose.
For anyone searching "mounjaro 5mg price uk", the current UK price for one 5mg Mounjaro pen is £174.99 at the discounted rate. The regular price is £204.99, while repeat orders are priced at £179.99.

Key things to know
- Mounjaro doses are measured in mg. "5ml" is a common but inaccurate way to refer to this strength
- Pricing is shown in three tiers: a regular price, a current price with a discount applied, and a Future Orders price for repeat orders
- 5mg is one of the doses reported separately in the SURMOUNT 1 trial, with an average weight loss figure for this strength
- 5mg is typically reached after 2.5mg rather than used as a starting dose, although your prescriber will decide your individual dose schedule
- Always check the exact current price at checkout, as prices shown on different pages of this site may vary
Current 5mg Pricing
| Pricing tier | Price |
|---|---|
| Regular price | £204.99 |
| Current price (with discount) | £174.99 |
| Future Orders price | £179.99 |
The regular price is the reference figure used to calculate the discount. The current price is what a new customer pays at the time of purchase. The Future Orders price applies to repeat orders for existing customers. If you expect to stay on this dose for more than one order cycle, this can help you plan your costs.
It is worth noting that this page has previously shown different figures for the 5mg dose (£199.99 regular, £159.99 first order, £174.99 returning), compared with the £204.99, £174.99 and £179.99 shown here and sourced from the live buy box. This is the second dose specific page found with a pricing difference compared with the confirmed buy box figures. It may be related to a template or caching issue. Always check the exact price at checkout before placing an order.
What Real Trial Data Shows for the 5mg Dose
Unlike some Mounjaro doses, 5mg is one of the three maintenance strengths, alongside 10mg and 15mg, reported separately in the SURMOUNT 1 trial, a major clinical study of tirzepatide. Mounjaro contains tirzepatide, which acts on GLP 1 and GIP receptors. At 72 weeks, participants taking 5mg had an average weight loss of 15.0% of their body weight, compared with 3.1% in the placebo group, using the trial's treatment regimen estimand. Using the efficacy estimand, which reflects results among people who continued treatment as planned, the average weight loss was 16.0%.
Individual results varied. In the same trial, 85% of people taking the 5mg dose achieved at least 5% weight loss, while 73% achieved at least 10%. These figures provide useful context because general claims such as "up to 20%" may refer to results seen with a higher dose. The 5mg dose also had its own results in the trial, so it is useful to look at dose specific data when discussing treatment. In SURMOUNT 1, average weight loss at the highest dose was 22.5% over 72 weeks.
It is important to remember that these figures are averages from a clinical trial and cannot predict the results for one particular person. Across clinical trials, average weight loss has varied depending on the dose, study and treatment period. Some people may notice a change in appetite during treatment, but this can vary from person to person. Your response may depend on factors such as your starting weight, diet, activity levels and how your body responds to the medicine. Your prescriber can help you understand what may be a realistic expectation for you rather than relying on trial averages alone.
Is 5mg a Starting Dose?
No. Treatment with Mounjaro starts at 2.5mg, the licensed starting dose, for at least the first four weeks. Mounjaro is available in weekly doses from 2.5mg to 15mg. 5mg is typically the first dose increase. Your prescriber will decide whether it is appropriate based on how you respond to and tolerate the 2.5mg dose. You should not start at 5mg unless your prescriber has advised you to do so.
In the original SURMOUNT 1 trial, participants increased their dose in 2.5mg steps at roughly four week intervals. This means that people who reached 5mg generally did so after the initial 2.5mg period. However, this does not mean that everyone will follow the same schedule. Your prescriber may recommend a different treatment plan based on your individual circumstances and how you respond to treatment.
Side Effects to Expect at 5mg
Common side effects of Mounjaro can include nausea, diarrhoea and vomiting, as well as reduced appetite and other digestive symptoms. These symptoms may appear or become more noticeable after a dose increase from 2.5mg. Dehydration can also occur if vomiting or diarrhoea continues. Injection site reactions may also occur. Mounjaro can affect blood sugar levels, and the risk of low blood sugar may be higher when it is used with certain diabetes medicines.
If side effects are more than mildly disruptive after moving to 5mg, speak with your prescriber. They can advise whether you should stay on your current dose for longer before considering another increase. Some side effects may become less noticeable as your body adjusts to treatment, but this can vary between people. Gallbladder problems, including gallstones, as well as severe or persistent abdominal pain, should be discussed with a healthcare professional promptly. Seek immediate medical attention if you experience signs of a serious allergic reaction.
How 5mg Compares to Other Doses
| Dose | Current price | Future Orders price |
|---|---|---|
| 2.5mg (starting dose) | £144.99 | £149.99 |
| 5mg | £174.99 | £179.99 |
| 7.5mg | £224.99 | £229.99 |
| 10mg | £244.99 | £249.99 |
| 12.5mg | £274.99 | £279.99 |
| 15mg (maximum) | £293.99 | £298.99 |
The price increases with each strength because the pens contain different amounts of active ingredient. However, a higher dose is not automatically the right goal for everyone. Your prescriber will decide which dose is appropriate for you based on your response and how well you tolerate treatment.
Estimating Annual Cost at 5mg
If your prescriber keeps you on 5mg for a full year, the Future Orders price of £179.99 per pen, with each pen covering 4 weeks, would mean approximately £2,339.87 for 13 pens. This is only an estimate for a full year at 5mg. Your actual first year cost may be lower because treatment normally starts at the 2.5mg dose, which is priced lower.
Bundle Options at 5mg
If your prescriber has confirmed 5mg as your ongoing dose, a multi pen bundle may offer a saving compared with ordering individual pens each cycle. Bundle prices can change, so check the current pricing table at checkout before ordering rather than relying on a bundle price shown elsewhere on the site.
What's Included in the Price
Every Mounjaro price includes an online clinical consultation with a UK registered prescriber, as Mounjaro is a prescription only medicine in the UK. It also includes your prescription and dispensing through our GPhC registered pharmacy. If you want to buy Mounjaro online, Mounjaro injections are supplied after a clinical assessment by a qualified healthcare professional. GPhC registration means the pharmacy is regulated under UK pharmacy standards. Medicines dispensed through regulated pharmacy premises are delivered in discreet packaging. Standard approval usually takes around 3 working days, with a paid express option available for a faster service.
Choosing the express option can speed up the review process, but it does not replace the clinical assessment. Your suitability for treatment still needs to be assessed by a healthcare professional before a prescription can be issued.
Supporting Your Results at 5mg
Mounjaro is licensed to be used alongside a reduced calorie diet and increased physical activity. The clinical trial results discussed above were also studied in this type of treatment setting. Eating a balanced diet with enough protein can be useful when you are trying to lose weight. Some of the weight lost during weight management can include lean tissue as well as fat, so maintaining a balanced diet and staying active can be helpful. If you are unsure how much protein or food you need, a healthcare professional or registered dietitian can offer personalised advice.
Regular eating patterns may also make it easier to maintain a balanced diet, particularly if your appetite is reduced. Mounjaro is intended to be used as part of a wider approach to weight management, including diet and physical activity. The injection can be taken with or without food, as advised in the product information. Your healthcare professional can explain how to fit your treatment into your normal routine. Healthy habits can also be useful when working towards long term weight management.
