What the evidence says about Wegovy, and why it requires a prescription

Wegovy is semaglutide, a GLP-1 receptor agonist made by Novo Nordisk. In the STEP 1 trial, published in the New England Journal of Medicine, adults treated with 2.4mg semaglutide over 68 weeks lost an average of around 15% of their body weight alongside lifestyle changes. That evidence base is precisely why the UK's Medicines and Healthcare products Regulatory Agency licensed it for weight management, and why it sits firmly in the Prescription-Only Medicine category.

Prescription-only status exists for clinical reasons, not bureaucratic ones. Semaglutide interacts with other medicines, is contraindicated in certain conditions, and requires careful dose titration by someone who can assess your full health picture. The NHS medicines page for semaglutide explains the licensed uses and side-effect profile in plain English. Reading it before starting any conversation about treatment is genuinely useful.

A prescriber, whether NHS or private, uses that evidence to make an individual decision, not a blanket one. BMI alone doesn't guarantee approval. Existing conditions, current medications and a verified identity all factor in. That's the clinical picture that makes treatment safe rather than risky.

How to get Wegovy legally in the UK

The route is straightforward, even if some sellers online try to make it look optional. You need a prescription from a qualified prescriber, dispensed by a pharmacy registered with the General Pharmaceutical Council. There is no legal shortcut.

Through a regulated private online pharmacy like nume, the process runs like this. You complete a free medical consultation, questions about your weight history, health conditions, current medicines and lifestyle. A GPhC-registered Independent Prescriber reads your answers personally and decides whether treatment is clinically appropriate. If it is, a prescription is issued and your medication is dispensed from our GPhC-registered pharmacy (registration 9012878) and dispatched the same day for free next-working-day delivery.

Before committing to any online pharmacy, spend 60 seconds on the GPhC's public register at pharmacyregulation.org to verify it holds a valid premises registration. A legitimate service will not only welcome that check, it will point you to it. If a seller can't be found on that register, walk away. Our guide to spotting legitimate Wegovy sources covers the specific questions worth asking.

The MHRA's warning about fake Wegovy pens, and why it matters here

When a medicine becomes high-profile, counterfeit supply follows. The MHRA has issued clear public warnings about fake weight-loss injection pens sold online and through social media. In 2025, enforcement operations seized approximately 20 million doses of illegally traded weight-loss medicines with an estimated street value of around £45 million, including the discovery of an illicit manufacturing site in Northampton producing counterfeit tirzepatide pens. Some fake pens have contained insulin rather than the labelled medicine.

The red flags are consistent: sellers offering these medicines without a prescription, prices far below anything on the legitimate market, and discount codes for prescription medicines from unverified accounts. If you want to understand what a genuine device should look like before you order, our guide to buying the Wegovy pen walks through what to check. Report anything suspicious to the MHRA's Yellow Card scheme, which accepts reports from patients as well as healthcare professionals.

Choosing a regulated route isn't just paperwork. It's the practical difference between a medicine that's been stored correctly in a licensed cold chain and something of unknown origin. You can read more about what genuine in-stock availability looks like on our Wegovy availability page.

Am I eligible? The basic outline

The licensed eligibility criteria for Wegovy in the UK centre on BMI: adults with a BMI of 30 or above, or 27 and above if at least one weight-related health condition is present, such as high blood pressure, high cholesterol, obstructive sleep apnoea or type 2 diabetes. Lower BMI thresholds apply for some ethnic backgrounds under UK clinical guidance. Wegovy is not licensed for under-18s, and it's not recommended during pregnancy, breastfeeding or if you're trying to conceive.

Meeting those numbers is a starting point, not a guarantee. A prescriber also looks at your medication list, medical history and any contraindications before deciding. That individual assessment is exactly what the 12pm cut-off is designed to support, submit before noon on a weekday and your case lands on a prescriber's desk the same afternoon, rather than waiting overnight.

If you'd like to understand the full treatment picture before starting a consultation, our Wegovy overview page covers how it works, the dosing schedule and what to expect. Patients sometimes also ask about when Wegovy became available to buy in the UK, and that page traces the regulatory timeline if you want the background. For a broader look at weight-management options, our weight-loss treatments page compares the approaches available through nume. When you're ready, start your free consultation to have your suitability assessed by one of our prescribers. If you're based outside the UK, our separate guide covers how to buy Wegovy in New Zealand.
