Most pages about weight loss treatment in the UK focus on one medicine and stop there. If you are searching for EveryDayMeds, it is a UK based, GPhC registered online pharmacy and private prescribing service that offers prescription treatments through remote consultations with UK registered healthcare professionals. Its services include weight management, contraception related care, erectile dysfunction treatment and private treatment for some skin conditions.
That is not much help if you are still deciding which treatment may be suitable for you. There are now weekly injections, daily tablets and older treatments that work in very different ways. Each option has its own benefits, side effects and prescribing considerations.
This guide is for UK adults aged 18 and over who are exploring private prescription weight loss treatment with clinical oversight and home delivery. It looks at the main prescription and pharmacy treatments used for weight management in the UK, what clinical evidence shows, who may qualify, how eligibility is assessed, what treatment can cost and what to check before ordering from a regulated online pharmacy such as EveryDayMeds.
There is no single best treatment for everyone. Weight management is a long term process, so it is important to understand how each medicine works, who it may be suitable for and how it should be used under clinical guidance.
Weight Loss Treatments Available in the UK
Several medicines are used for weight management in the UK. Their clinical evidence comes from different studies, so the figures below should be treated as separate trial results rather than a direct ranking of the medicines.
| Treatment | Active ingredient | How it is taken | Average weight loss in trials |
|---|---|---|---|
| Mounjaro | Tirzepatide | Weekly injection | 15.0% to 20.9% over 72 weeks by dose |
| Wegovy | Semaglutide | Weekly injection | Around 15% over 68 weeks |
| Wegovy pill | Oral semaglutide 25mg | Daily tablet | Around 13.6% over 64 weeks |
| Saxenda | Liraglutide | Daily injection | Smaller than the weekly GLP 1 options |
| Mysimba | Naltrexone and bupropion | Daily tablet | Around 8.1% over 56 weeks |
| Xenical or orlistat 120mg | Orlistat | Capsule with meals | Modest, and dependent on dietary fat |
| Alli or Orlos 60mg | Orlistat, lower strength | Capsule with meals | Smaller again, sold without prescription |
There are some important differences that the table does not show. Mounjaro contains tirzepatide, which acts on both GIP and GLP 1 receptors. Wegovy contains semaglutide, which acts on the GLP 1 receptor.
Wegovy also has an indication for reducing the risk of major cardiovascular events in certain adults with established cardiovascular disease and overweight or obesity. This is a separate indication and does not mean that it is the right treatment for everyone with heart problems.
The Wegovy tablet, approved by the MHRA in June 2026, contains oral semaglutide and is a different product from Rybelsus. Rybelsus also contains oral semaglutide but is licensed for type 2 diabetes rather than weight management.
Orlistat works differently from the injectable medicines. It blocks some of the fat from food being absorbed in the gut. This means its effects and side effects are different from medicines that act on appetite and other hormone pathways.
Naltrexone and bupropion, sold as Mysimba, also work differently from GLP 1 medicines. However, NICE does not currently recommend naltrexone and bupropion for weight management. Prescribing decisions should therefore take account of current UK guidance as well as the product licence.
It is also worth checking claims about medicines that are available overseas. Orforglipron has been approved in the United States but is not currently licensed in the UK. Retatrutide is still being studied and is not an approved UK weight management medicine.
What Is the Best Weight Loss Treatment?
There is no single weight loss medicine that is best for everyone. The more useful question is which option is appropriate for your circumstances.
Your prescriber may consider factors such as how the medicine is taken, your medical history, other medicines you use, how well you tolerate treatment and the cost of ongoing treatment.
| If this matters most to you | Worth discussing with your prescriber | Why |
|---|---|---|
| Avoiding needles | A daily oral option | Tablets do not require an injection or sharps disposal |
| Frequent travel | An oral option | Some oral medicines may be easier to manage while travelling |
| Fewest doses to remember | A weekly injection | One dose a week rather than one a day |
| Existing heart health concerns | Discuss the relevant licence | Some medicines have specific cardiovascular indications |
| Lower treatment cost | Orlistat | Usually costs less, although its average weight loss is smaller |
| Previous poor tolerance of GLP 1 medicines | A non GLP 1 option | A different mechanism and side effect profile may be considered |
Your prescriber will decide whether a treatment is appropriate after reviewing your medical history, current medicines and relevant health conditions. No medicine can guarantee a particular amount of weight loss, and individual results vary.
Who Can Get Prescription Weight Loss Treatment in the UK
Private prescribing follows the licensed use of each medicine, but the exact assessment criteria can vary between treatments and providers. Your prescriber will look at your BMI, medical history, current medicines and other relevant factors before deciding whether treatment is suitable.
For some weight management medicines, treatment may be considered for adults with a BMI of 30 or above, or 27 or above where there is a weight related health condition or other relevant risk factor, such as high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea.
Lower BMI thresholds, usually reduced by around 2.5 kg/m², are recommended for people from South Asian, Chinese, other Asian, Middle Eastern, Black African and African Caribbean backgrounds for certain weight management medicines.
NHS access is different from private prescribing. For example, NICE recommends tirzepatide through NHS services only for adults who meet specific criteria, including an initial BMI of at least 35 kg/m² and at least one weight related health condition, with lower BMI thresholds for certain ethnic groups. NHS access is also being introduced in phases.
This means that private and NHS eligibility can be different. Someone who does not meet the current NHS criteria is not simply waiting longer for the same treatment.
Treatment is not suitable for everyone. Pregnancy, plans for pregnancy, breastfeeding, previous pancreatitis, gallbladder problems, kidney or liver conditions and other medicines can all affect whether a particular treatment is appropriate. The specific precautions differ between medicines, so your prescriber should assess your individual circumstances rather than relying on a general eligibility checklist.
Mounjaro Weight Loss Treatment: Doses and Evidence
Mounjaro is one of the prescription weight management treatments available in the UK. It contains tirzepatide, which acts on both the GLP 1 and GIP receptors.
Mounjaro is made by Eli Lilly and was authorised for weight management in eligible UK adults in 2023. It is injected once a week using a KwikPen containing four weekly doses.
Six strengths are available: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg. Treatment usually starts at 2.5mg once a week. If an increase is appropriate, there should be at least 4 weeks between dose increases. Your prescriber decides whether and when to increase the dose based on your response and how well you tolerate treatment.
The main evidence includes the SURMOUNT 1 trial, which studied 2,539 adults with obesity or overweight with a weight related health condition over 72 weeks. The study was carried out alongside a reduced calorie diet and increased physical activity.
Average weight reduction was 15.0% with 5mg, 19.5% with 10mg and 20.9% with 15mg, compared with 3.1% with placebo. At least 5% of body weight was lost by 85%, 89% and 91% of participants on those doses respectively.
These figures show what happened on average in a clinical trial. They are not a promise of what you will lose. Individual results can vary.
Mounjaro can also affect blood glucose levels. If you take medicines for diabetes, particularly insulin or medicines called sulphonylureas, your prescriber may need to consider the risk of low blood sugar and review your treatment.
The 5mg result is also useful because it shows that higher doses are not automatically required for everyone. Your prescriber can decide whether staying at a lower dose or increasing the dose is appropriate for you.
Full detail is on the Mounjaro weight loss treatment page.
What Weight Loss Treatment Costs
Private treatment is usually self funded, and prices can vary between medicines, strengths, pharmacies and treatment services. The figures below are focused on Mounjaro rather than every available treatment.
Each Mounjaro pen contains four weekly doses. If you stayed on the same strength for 52 weeks, you would need thirteen pens rather than twelve.
Some costs may be separate from the medicine itself. Mounjaro KwikPens are supplied without needles, so compatible pen needles need to be purchased separately. A suitable sharps bin may also be needed for safe disposal. Oral treatments do not require injection needles or sharps disposal.
Orlistat is generally less expensive than injectable weight management medicines, although its weight loss effect and side effect profile are different. Cost is therefore only one factor to consider when choosing treatment.
When comparing providers, look at the standard price for the same strength rather than focusing only on a first order discount. It is also useful to compare delivery charges, consultation fees, repeat order prices and the estimated cost over 12 months.
Prices are correct at the time of writing and the live price at checkout always takes precedence.
How Long Does Weight Loss Treatment Last?
There is no single fixed treatment length for everyone. Weight management is often a long term process, and medicines can help manage weight rather than permanently cure obesity.
How long you continue treatment depends on your response, side effects, health needs and the advice of your prescriber.
Some people may continue treatment for a longer period, while others may stop or change treatment after a review. If treatment is stopped, some people regain weight because the effects of the medicine on appetite and other processes involved in weight management are no longer present.
For some medicines, clinical guidance includes specific points for reviewing whether treatment should continue. For example, NICE recommends reviewing tirzepatide if less than 5% of initial weight has been lost after 6 months on the highest tolerated dose.
Do not stop, reduce or restart a prescription weight loss medicine without speaking to your prescriber. A treatment plan can be adjusted based on how you are responding.
Long term weight management should focus on overall health rather than rapid weight loss. A balanced diet, suitable physical activity and appropriate clinical monitoring remain important alongside medication.
Where to Get Weight Loss Treatment: Online, Pharmacy or GP
Searches for "weight loss treatment near me" often assume that a local service will be faster. However, prescription weight loss medicines still require an appropriate clinical assessment and prescription whether you use a high street pharmacy, private clinic or online service.
With an online service, the consultation usually takes place remotely. You may be asked questions about your weight, height, medical history, current medicines and previous treatment. A prescriber then decides whether the medicine is appropriate.
Supermarket pharmacies, independent pharmacies and online services can all offer different services and prices. Whether a particular provider is currently offering a specific medicine or price should be checked directly with that provider.
The most important thing is to check that the pharmacy is properly regulated. Look for the pharmacy on the General Pharmaceutical Council register and check that a suitably qualified prescriber is involved in the assessment.
A genuine assessment should be capable of deciding that treatment is not suitable for you. Be cautious of websites offering prescription medicines without a proper clinical assessment or at unusually low prices.
EveryDayMeds trades as OVIO LTD and dispenses from GPhC registered premises, registration number 9012878.
The MHRA has also warned about falsified Mounjaro pens. In February 2026, it reported falsified 15mg Mounjaro KwikPens with batch number D873576 that had been supplied through one UK online pharmacy. This is a useful reminder to obtain prescription medicines through legitimate, regulated supply routes.
How Ordering Works, and What to Expect
- Free online consultation as part of EveryDayMeds' prescription weight management service. This can cover your weight, height, BMI, medical history, current medicines and previous weight management treatment.
- Clinical review by a UK registered prescriber and clinical team. They may ask additional questions if they need more information before making a prescribing decision. An express service may reduce processing time, but it does not remove the required clinical checks.
- Dispensing by the GPhC registered pharmacy if treatment is approved. This may include prescription only weight loss medicines where they are clinically appropriate.
- Delivery by a tracked service in suitable packaging. Medicines that require refrigeration should be stored according to their product instructions. Mounjaro should be stored at 2°C to 8°C before first use and should not be frozen.
Weight loss medicines can cause side effects, and the type and frequency depend on the medicine. With GLP 1 based medicines such as Mounjaro and Wegovy, commonly reported effects include nausea, diarrhoea, vomiting, constipation, abdominal discomfort and reduced appetite. These effects can be more noticeable when treatment starts or when the dose is increased.
Severe or persistent abdominal pain should be assessed urgently, particularly if it may indicate pancreatitis. Severe allergic reactions also require urgent medical attention.
If you take medicines for diabetes, speak to your healthcare team if you develop symptoms that could indicate low blood sugar. Your diabetes medicines may need to be reviewed when starting or changing weight management treatment.
Check the Patient Information Leaflet for the specific medicine you are using, as warnings and side effects differ between treatments.
Side effects and suspected adverse reactions can be reported through the MHRA Yellow Card Scheme. The MHRA also provides safety information about medicines used for weight management.
