GLP-1 Doctors in the UK: Who Can Prescribe and How to Get Help (October 2026)

01 · The core answer

Which doctor can prescribe a GLP-1 medicine?

Any appropriately qualified UK prescriber can prescribe a GLP-1 or GIP/GLP-1 medicine for weight management, provided they judge it suitable for you. In practice that means your GP, a consultant or specialist team, or a GPhC-registered prescriber. There is no separate qualification called 'GLP-1 doctor'. What matters is a proper assessment of your health, medicines and goals.

If you are asking what kind of doctor you should see, start with your GP. They hold your medical history, know your other medicines and can refer you to a specialist weight-management service if you meet NHS criteria. If you would rather not wait, a regulated online pharmacy is a second route. For a deeper look at prescribing habits, see our guide on whether doctors prescribe GLP-1 medicines.

02 · Your decision

Should you go through the NHS or privately?

Choose the NHS first if you may meet the criteria and can wait; choose private treatment if you meet the licensed criteria but not the NHS thresholds, or do not want to wait. Mounjaro is available on the NHS, but access is being phased in over several years. NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition, and the primary-care rollout began in June 2025 with the highest-need groups first.⁴⁶

Because full rollout is expected to take years, many people who meet the licensed criteria choose regulated private treatment rather than waiting. The two routes are not mutually exclusive: you can ask your GP about NHS access while exploring private options. If you start privately, tell your GP, as they hold the full picture of your health.

When cost matters, your first 2.5mg pen costs £129.99 with code FIRST40 (standard price £169.99). Prices checked 10 October 2026. You can see the Mounjaro pen page, and our wider weight loss clinic for other options.

03 · How doctors decide

How do doctors decide whether a GLP-1 is right for you?

Doctors decide by matching your health history against the medicine's licence, national guidance and safety information. They are not looking for a single number. They build a picture from several things, and each one can change the answer.

First comes the licensed indication. Mounjaro is licensed in the UK for weight management in adults and for type 2 diabetes.¹ A prescriber checks that your situation fits the licence, including your BMI and any weight-related conditions. For NHS prescribing, the NICE guidance sets a further threshold: a BMI of at least 35 plus at least one weight-related condition.⁴

Second comes safety. A prescriber reviews your current medicines, past medical history, pregnancy plans and anything in the product information that would make treatment unsuitable. Mounjaro must not be used during pregnancy, and it should be stopped at least one month before trying to conceive. If you become pregnant during treatment, stop the medicine and tell your prescriber promptly. The prescribing reference for tirzepatide is the BNF, and the patient information leaflet lists the warnings you should read before starting.¹¹¹³

Third comes expectations. These medicines work alongside a reduced-calorie diet and increased physical activity, not instead of them. A good prescriber will ask what support you have in place and what you have already tried, because medicine is one part of a plan.

Finally, they consider whether you can follow the treatment. That means a once-weekly injection, regular review and honest reporting of side effects. If any of these are a concern, a doctor may suggest a different approach or ask you to come back later.

04 · Why a GP may say no

Why won't my doctor prescribe weight loss medication?

The most common reason is that NHS access is still being phased in, so your GP may be unable to prescribe on the NHS even when treatment would be clinically reasonable. Rollout began with the highest-need groups first, and it will take years to widen.⁶

Other reasons are clinical. Your doctor may think a medicine is unsuitable because of another condition or another medicine you take. They may want you to try structured lifestyle support first. Or they may not meet the national criteria for your BMI and conditions.⁴

If you are told no, ask three practical questions:

• Is the refusal about NHS criteria, or about safety for me specifically?
• Could I be referred to a specialist weight-management service?
• What would change your answer, and when should I come back?

A refusal about NHS criteria is different from a refusal on safety grounds. If the reason is safety, take it seriously and do not simply look for another prescriber. If the reason is access, regulated private treatment may be an option, but the same safety checks still apply.

Whatever route you choose, check that any pharmacy is on the GPhC register. We are GPhC-registered, number 9012878.¹²

05 · Online prescribing explained

Can you get a GLP-1 without a doctor visit?

You cannot legitimately get a GLP-1 medicine without a clinical assessment, but that assessment does not have to be a face-to-face surgery appointment. These are prescription-only medicines. A regulated online pharmacy gathers your health information through a questionnaire, and a GPhC-registered prescriber reviews it before anything is supplied.

That is how our service works. The steps are:

• You complete a free online consultation, a short health questionnaire with no charge and no obligation.
• A GPhC-registered prescriber reviews it. This is a clinician's decision, not a scoring script. Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full.
• Our registered pharmacy dispenses the medicine, with same-day dispatch when ordered by 3pm.
• Delivery is free, next-day and tracked, in temperature-controlled, discreet packaging.

Be wary of anyone offering to supply without a consultation or prescription. The MHRA publishes counterfeit medicine alerts and runs the Yellow Card scheme for suspected side effects and fake products.⁷ We supply Mounjaro through official LillyDirect supply, sourced directly from Eli Lilly's UK distribution, as genuine KwikPens.

Online care is not a lesser form of care when it is done properly. The test is simple: is there a real prescriber, a real pharmacy and a real follow-up? Our aftercare includes ongoing monthly reviews, dose-titration and follow-up assessments, and side-effect support. Repeat orders re-check suitability, and nothing is auto-shipped.

06 · Doctors and pharmacists

How doctors and pharmacists work together on GLP-1 care

Doctors and pharmacists share responsibility: the prescriber decides whether treatment is appropriate, and the pharmacist checks and dispenses it safely. Neither role replaces the other, and collaboration between them is what keeps GLP-1 management safe for patients.

A prescriber assesses the clinical case, chooses the medicine and agrees a plan. The dispensing pharmacy then checks the prescription, makes sure the product is genuine and supplies the pen with the leaflet and guidance for use. In our service, needles, a sharps bin and injection guidance come with every order.

Collaboration continues after the first pen. Practical matters a pharmacist or prescriber can help with include:

• How to store pens: keep them in the fridge at 2–8°C and never freeze them; once a pen is in use it can be kept out of the fridge at a temperature not above 30°C for up to 30 days, and must then be thrown away.¹
• What to do about side effects, and when to report them through the Yellow Card scheme.¹⁹
• Checking other medicines you take, including oral contraceptives, with the patient information leaflet as the reference.¹³ The SmPC advises switching to a non-oral method, or adding a barrier method (such as condoms), for 4 weeks after starting Mounjaro and for 4 weeks after each dose increase.¹

If you take insulin or a sulfonylurea, your doses may need adjusting because of the risk of low blood sugar, so raise it with your prescriber before starting. We also offer the free GLPTrackr app to help you log your journey and bring clearer information to every review.

07 · What results to expect

What can a doctor tell you about results?

A good doctor will give you trial averages with caveats, never promises. The headline evidence for Mounjaro comes from SURMOUNT-1. In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of their body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, compared with 3.1% with lifestyle changes alone.²

These are trial averages. Individual results vary, and treatment works alongside a reduced-calorie diet and increased physical activity, not instead of them. For someone starting at 100 kg, 20.9% is about 21 kg, but that is a worked example of an average, not a prediction for you.

Doctors also explain how the medicine works. Tirzepatide activates two natural gut-hormone receptors at once, GIP and GLP-1. Together these help regulate appetite, slow how quickly the stomach empties, and improve the way the body responds to insulin. In practice, most people feel fuller sooner and less hungry between meals, which supports a reduced-calorie diet.¹

It is also worth asking about stopping. Tirzepatide has a half-life of about five days, so after a final dose it takes roughly four to five weeks to clear the system. There is no way to speed this up, and nothing needs doing while it clears.

08 · Training for clinicians

Is there a GLP-1 course for doctors?

If you are a clinician looking for a GLP-1 course, the right place to start is your professional body, your employer's training team or accredited continuing professional development providers. We do not run a clinician course.

The reference material most prescribers rely on is public. The NICE guidance on tirzepatide for overweight and obesity includes a practical prescribing guide, and the BNF carries indications, dosing and safety information.⁴¹¹ Prescribers also work from the SmPC for each product.

A sound course should cover the licence, patient selection, shared decision-making, side-effect management, interactions and follow-up. Be cautious about any training that promises specific outcomes or treats these medicines as lifestyle products. They are prescription medicines with real risks and benefits.

If you are a patient reading this because you want a better-informed conversation with your doctor, the same list helps you. Ask what they will review, how they will monitor you and when treatment would stop.

09 · Supplements and shortcuts

What about 'poor man's Ozempic' and supplements?

The phrase 'poor man's Ozempic' is marketing slang for low-cost supplements, not a medicine. These products are available cheaply without assessment, and they carry no clinical oversight. Dosing is not standardised, and dramatic weight-loss claims attached to them should be treated with scepticism.

A supplement is not a GLP-1 medicine and cannot be compared with one. If you are curious about the category, our page on GLP-1 support supplements explains what they can and cannot do.

Health claims about research areas can also run ahead of evidence. For example, early-stage research on GLP-1 and remyelination is not a reason to seek treatment.

If a product promises results without a consultation, a prescription or a registered pharmacy behind it, step away. You can report suspected fake or unsafe products to the MHRA.⁷

10 · Serious side effects

Serious side effects: when to get help straight away

Serious side effects are uncommon but need urgent attention. Seek immediate medical help for: severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of skin/eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing. If you take insulin or a sulfonylurea alongside Mounjaro, watch for low blood sugar (shakiness, sweating, confusion) — your prescriber may need to adjust those medicines.¹
