If you are searching for tirzepatide in the UK, you are probably looking for Mounjaro, the once weekly injection that contains the active ingredient tirzepatide. It is a prescription only medicine, so it cannot be bought without a clinical assessment. It can, however, be prescribed through a registered UK pharmacy when a qualified prescriber decides that it is suitable for you.
This guide explains what tirzepatide is, who it may be suitable for, what the Synedica tirzepatide 40mg price means, how the ordering process works, and how to check that a pharmacy is genuine.
This page brings together information about tirzepatide pricing, buying options, eligibility, clinical evidence, side effects and the treatment journey in one place. We also cover the importance of a healthy diet, regular physical activity and ongoing support when using tirzepatide for weight management.
You will also find information about maintenance doses, reduced calorie intake, possible side effects, missed doses and storage. We explain how tirzepatide works through two hormone receptor pathways, GIP and GLP 1, which are involved in appetite and blood glucose regulation.
We also cover important safety information, including common side effects such as nausea, diarrhoea, constipation and reduced appetite. More serious problems, including pancreatitis and severe allergic reactions, are less common but require medical attention if they occur. Understanding your prescribed dose, what to do if you miss a dose and how to store your pen correctly can help you use the medicine safely.
Finally, we discuss products sold online as compounded, unlicensed or over the counter tirzepatide. These products may not have been assessed or authorised by the MHRA, so it is important to use a legitimate pharmacy and a medicine supplied following an appropriate clinical assessment.
If you are interested in Mounjaro in the UK, this guide can help you understand how tirzepatide treatment works, what you may need to pay and what to look for when choosing a pharmacy.
What Is Tirzepatide?
Tirzepatide is the active ingredient in Mounjaro, a medicine developed by Eli Lilly. It is a dual GIP and GLP 1 receptor agonist, which means it acts on two different hormone receptor pathways.
In the UK, Mounjaro is authorised for weight management in adults with obesity or overweight with at least one weight related health condition. It is also authorised for treating type 2 diabetes in adults and certain younger patients. For weight management, it is used alongside a reduced calorie diet and increased physical activity.
Tirzepatide is given as a once weekly injection under the skin using a pre filled KwikPen. Each KwikPen contains 4 doses. The available adult strengths include 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg.
EveryDayMeds orders are reviewed by a qualified prescriber before treatment is supplied. Treatment is only prescribed where the prescriber considers it clinically appropriate for the individual. You can explore the full range of prescription weight loss treatments available through our Weight Loss Hub.
Do Tirzepatide Tablets or Capsules Exist?
Tirzepatide is currently supplied as an injection in the UK. If you see a website selling a product described as a tirzepatide tablet, capsule or pill, check carefully whether it is an authorised medicine before buying it.
Products sold online as tirzepatide without an appropriate prescription or from an unregulated source may not contain what the packaging claims. This creates avoidable safety risks.
If you prefer a tablet rather than an injection, there are now other authorised oral medicines for weight management in the UK. In June 2026, the MHRA approved a once daily semaglutide tablet for weight loss and weight management. Semaglutide is a different active ingredient from tirzepatide and works through the GLP 1 pathway.
You can read more on our oral GLP-1 weight loss page if you would like to learn about oral treatment options.
How Tirzepatide Works
Tirzepatide activates GIP and GLP 1 receptors, which are involved in appetite and blood glucose regulation. It can help people feel fuller, reduce hunger and make it easier to eat less. It also slows gastric emptying, which can contribute to feelings of fullness.
Tirzepatide can also help improve blood glucose control, which is why Mounjaro is also authorised for the treatment of type 2 diabetes.
The response is different for each person. Weight loss can depend on factors such as your starting weight, prescribed dose, diet, physical activity, other medicines and individual response to treatment. Tirzepatide should be used alongside a reduced calorie diet and increased physical activity rather than as a replacement for healthy lifestyle changes.
Who Tirzepatide Is Suitable For
There are two different points to understand when looking at eligibility: the UK marketing authorisation and the criteria for NHS treatment.
Under the UK marketing authorisation, Mounjaro can be used for weight management in adults with an initial BMI of 30kg/m² or above, or with a BMI of 27kg/m² to less than 30kg/m² where there is at least one weight related health condition. Examples include high blood pressure, abnormal blood fats, obstructive sleep apnoea, cardiovascular disease, prediabetes and type 2 diabetes.
For people from South Asian, Chinese, other Asian, Middle Eastern, Black African or African Caribbean ethnic backgrounds, lower BMI thresholds are generally used because health risks linked with excess weight can occur at lower BMI levels.
NHS access is more restricted during the current phased rollout. NICE recommends NHS funded tirzepatide for adults with an initial BMI of at least 35kg/m² and at least one weight related health condition, with lower BMI thresholds usually applying to certain ethnic groups.
| Consideration | Typical guidance |
|---|---|
| Body Mass Index | The UK marketing authorisation covers a BMI of 30 or above, or 27 to less than 30 with at least one weight related health condition |
| NHS eligibility | NICE currently recommends NHS treatment for adults with a BMI of at least 35 and at least one weight related health condition, subject to the phased rollout |
| Ethnicity adjustment | Lower BMI thresholds are generally used for people from South Asian, Chinese, other Asian, Middle Eastern, Black African or African Caribbean ethnic backgrounds |
| Weight related conditions | Examples include type 2 diabetes, high blood pressure, abnormal blood fats, obstructive sleep apnoea, cardiovascular disease and prediabetes |
| Not suitable or requiring careful assessment | Pregnancy, certain medical conditions, some medicines and allergies may affect whether treatment is appropriate |
This table is a general guide only. Private prescribing criteria may differ from NHS funding criteria, and final suitability must be decided by a qualified prescriber after reviewing your medical history, current medicines and individual circumstances.
How Much Weight Can You Lose With Tirzepatide?
Clinical trials have shown that tirzepatide can lead to substantial weight loss when used alongside a reduced calorie diet and increased physical activity. In SURMOUNT 1, average weight loss at 72 weeks was around 15% with 5mg, 19.5% with 10mg and 20.9% with 15mg in the main analysis. Results varied between individuals.
These figures come from clinical trials and should not be treated as a personal target or guarantee. Your results may be different depending on your starting weight, treatment dose, lifestyle, health and individual response.
The Clinical Evidence Behind Tirzepatide
Tirzepatide's weight management authorisation is supported by the SURMOUNT clinical trial programme. SURMOUNT 1 included 2,539 adults with obesity, or overweight with at least one weight related health condition, and followed participants for 72 weeks. Participants received tirzepatide at 5mg, 10mg or 15mg once weekly, or placebo, alongside lifestyle support.
At 72 weeks, average weight loss was substantially greater in the tirzepatide groups than in the placebo group. However, these are average results from a clinical trial and do not predict exactly how much weight one person will lose.
NICE reviewed this and other evidence when it published TA1026. Tirzepatide is recommended as an option for NHS management of overweight and obesity in eligible adults, alongside a reduced calorie diet and increased physical activity. NICE also recommends reviewing treatment if less than 5% of the person's initial weight has been lost after 6 months on the highest tolerated dose. The decision to continue should take into account the benefits and risks for that individual.
Tirzepatide is also recommended by NICE for certain adults with type 2 diabetes under separate guidance, TA924.
Mounjaro is authorised in the UK for weight management and is given once weekly. It is injected under the skin of the abdomen, thigh or back of the upper arm. If you inject it yourself, the upper arm should only be used when another person gives the injection. Injection sites should be rotated.
The dose is increased gradually. Adults normally start with 2.5mg once a week for 4 weeks, followed by 5mg once a week. If needed, the dose can then be increased in 2.5mg steps, with at least 4 weeks at each dose, up to a maximum of 15mg once a week. Your prescriber will decide whether and when your dose should increase.
If you miss a dose, the current UK product information advises taking it within 4 days of the missed dose. If more than 4 days have passed, skip the missed dose and take your next dose on your usual day. Do not take two doses within 3 days of each other.
Mounjaro also needs to be stored correctly. Before first use, it should be kept in a refrigerator at 2°C to 8°C and must not be frozen. After first use, a KwikPen can be stored unrefrigerated at a temperature not above 30°C for up to 30 days, after which it must be discarded. Always follow the storage instructions supplied with your medicine.
You may also see compounded or unlicensed products marketed as tirzepatide. These are different from an authorised Mounjaro product and may not have the same regulatory checks. If you are considering any medicine sold as tirzepatide, make sure it has been supplied through a legitimate prescribing and pharmacy process.
How Ordering Tirzepatide Through EveryDayMeds Works
EveryDayMeds is a GPhC registered UK pharmacy, operated by OVIO Ltd from a registered pharmacy premises in Leicester. The process is designed to make the clinical checks clear because tirzepatide is a prescription only medicine.
- Complete an online assessment. You answer questions about your health, weight, medical history and current medication. This can be started from our weight loss consultation page.
- Clinical review. A qualified independent prescriber reviews the information you provide and considers whether treatment may be suitable for you. They may contact you if more information is needed.
- Identity and weight verification. You may be asked to provide information or evidence needed to support safe prescribing and to confirm your identity and weight. If you are transferring from another provider, you may also be asked for information about your previous treatment.
- Prescribing decision. If the prescriber decides that tirzepatide is clinically appropriate, a private prescription is issued and the medicine can then be dispensed.
- Dispatch and delivery. Approved orders are dispatched using appropriate packaging and tracked delivery, with storage requirements taken into account because Mounjaro is temperature sensitive.
If treatment is not clinically appropriate, the prescriber will not issue a prescription. This clinical review is an important part of safe online prescribing.

Price should not be the only thing you consider when choosing a pharmacy. Make sure the service includes an appropriate clinical assessment and that the medicine is supplied by a regulated pharmacy.
Understanding Synedica Tirzepatide 40mg Price and Cost Factors
Synedica is not the brand name of the authorised Mounjaro product in the UK. Mounjaro contains tirzepatide and is the authorised brand supplied by Eli Lilly.
If you are searching for the "Synedica tirzepatide 40mg price", be careful about comparing an unlicensed or compounded product with an authorised Mounjaro pen. The products may differ in formulation, strength, packaging, regulatory status and how they are supplied.
A price that appears lower does not necessarily mean that the product is a safer or better option. Before buying any medicine described as tirzepatide, check who is prescribing it, which pharmacy is dispensing it and whether the product is authorised for use in the UK.
For an authorised Mounjaro product, the prescribed strength and dosing instructions should come from your prescriber. Do not try to calculate or adjust your dose based on the price or total amount of tirzepatide stated on a product.
A Smart Buyer's Guide: Questions Worth Asking Before You Order
Because tirzepatide is a prescription only medicine and there are many online services offering weight management treatment, it is worth doing a few checks before placing an order.
Is the pharmacy genuinely GPhC registered? Check the pharmacy on the General Pharmaceutical Council's public register instead of relying only on a registration number displayed on the website.
Is the price you see the full price? Check whether the quoted price includes the clinical consultation, prescription, needles, delivery and any other fees. Our prescribing and dispensing policy explains what is included with your order.
Is there a real clinical assessment? A legitimate prescription service should collect relevant information about your health, medical history and current medicines before a prescription is issued.
Are you being asked to change your dose yourself? You should not increase, decrease or change your Mounjaro dose without advice from your prescriber. The UK dosing schedule requires at least 4 weeks at a dose before an increase is considered.
Does the medicine arrive with appropriate storage instructions? Mounjaro needs to be stored correctly, particularly before first use. Check the packaging and patient information leaflet when your order arrives.
Injection or Pill: Comparing GLP 1 Options
Many people search for tirzepatide because they want a medically supervised weight management option, but an injection may not be their preferred method. There are now oral weight management medicines available in the UK, although they contain different active ingredients from tirzepatide.
| Feature | Mounjaro (tirzepatide) injection | Daily oral GLP 1 tablet |
|---|---|---|
| Dosing frequency | Once weekly | Once daily |
| Method | Subcutaneous injection via pre filled pen | Swallowed tablet |
| Storage | Refrigerated before first use, subject to product storage instructions | Follow the storage instructions for the specific medicine |
| Needles required | Yes | No |
| Clinical evidence base | Extensive clinical trial programme, including SURMOUNT | Separate clinical trial evidence |
Neither option is automatically better for everyone. The right choice depends on factors such as your health, medical history, treatment goals, preference for injections or tablets and the advice of your prescriber.
If needles are a concern, mention this during your consultation. You can also explore the oral GLP-1 weight loss option.
Safety, Side Effects and Who Should Be Cautious
Like any prescription medicine, tirzepatide can cause side effects and is not suitable for everyone.
Common side effects include nausea, diarrhoea, constipation, vomiting and reduced appetite. Gastrointestinal side effects are particularly common during dose increases and may become less noticeable over time for some people.
More serious problems can occur less commonly. These include pancreatitis, gallbladder problems and serious allergic reactions. If you develop severe or persistent abdominal pain, swelling of the face or throat, difficulty breathing or another serious symptom, seek medical attention promptly.
Tirzepatide can increase the risk of low blood sugar when used with insulin or sulphonylureas. Your prescriber may need to consider adjustments to these medicines and may advise you to monitor your blood glucose.
Tirzepatide also delays gastric emptying. People with severe gastrointestinal disease, including severe gastroparesis, should be assessed carefully before treatment.
If you use an oral contraceptive and have overweight or obesity, speak to your prescriber about contraception. Tirzepatide can affect the absorption of oral contraceptives, particularly when treatment is started or the dose is increased. The UK product information recommends a non oral contraceptive or an additional barrier method for 4 weeks after starting tirzepatide and for 4 weeks after each dose increase.
Tirzepatide should not be used during pregnancy. If you become pregnant while taking Mounjaro, contact your prescriber. If you are planning a pregnancy, discuss your treatment with your healthcare professional in advance.
Always read the patient information leaflet supplied with your medicine. If you are unsure about side effects, your dose or whether Mounjaro is suitable for you, speak to your prescriber or pharmacist.
Delivery, Storage and What Arrives With Your Order
Mounjaro needs to be stored within a specific temperature range, particularly before first use. The UK product information states that unopened pens should be stored in a refrigerator at 2°C to 8°C and must not be frozen. After first use, the KwikPen can be stored unrefrigerated at a temperature not above 30°C for up to 30 days before it must be discarded.
When your order arrives, check the pen, packaging and expiry date. Do not use the medicine if the pen is damaged, the medicine has been frozen, or the solution is cloudy, discoloured or contains particles.
EveryDayMeds orders for injectable treatment include the prescribed Mounjaro pen, compatible needles and alcohol swabs, with tracked delivery included as standard. The exact contents of an order can depend on the treatment and current service arrangements.
