How to Get Wegovy: the Legal Route in the UK, Step by Step

What NICE and the MHRA require before a prescription can be written

Wegovy (semaglutide 2.4mg, made by Novo Nordisk) is licensed in the UK for adults with a BMI of 30 or above, or 27 or above when at least one weight-related condition (such as high blood pressure, type 2 diabetes or high cholesterol) is present. Those figures can apply at a lower threshold for some ethnic backgrounds under UK guidance. NICE's appraisal of semaglutide for weight management (TA875) sets additional criteria for NHS use, including treatment within a specialist service.

None of this changes the fundamental legal point: Wegovy is a Prescription-Only Medicine under the Human Medicines Regulations 2012. A registered prescriber must assess you, satisfy themselves you meet the criteria, and issue a valid UK prescription before the medicine can be supplied. That assessment covers your medical history, current medicines, weight, and any conditions that might make treatment unsuitable or require closer monitoring. The NHS medicines page for semaglutide sets out what a prescriber considers. It is a clinical decision, and it should be.

Trial data from the STEP 1 study, published in the New England Journal of Medicine, showed average weight reductions of around 15% over 68 weeks at the 2.4mg maintenance dose. Results like that are why demand is high, and why sellers operating outside the prescription system are a serious problem.

The fastest legitimate way to get a Wegovy prescription in the UK

There are two lawful routes: NHS and private. On the NHS, Wegovy is available through specialist weight management services under TA875, and waiting times can be considerable in many areas. For people who do not meet NHS criteria or prefer not to wait, a regulated private online pharmacy is the practical alternative, provided you choose one you can actually verify.

At nume, the process runs like this. You complete a free health consultation online. A GPhC-registered Independent Prescriber reviews your answers the same day, your case lands on a prescriber's desk, not in a processing queue. If treatment is clinically suitable, a prescription is issued and your order is dispatched before the day is out. A full picture of what the online process involves is worth reading before you start.

Before choosing any online pharmacy, check it on the GPhC pharmacy register. Every legitimate UK online pharmacy dispensing prescription medicines has a premises registration number you can look up in seconds. Ours is 9012878. If a pharmacy cannot be found there, do not use it.

The fake-pen risk and why it matters for anyone searching online

The MHRA has issued repeated warnings about counterfeit weight-loss pens sold online and through social media. In October 2025 enforcement teams raided a site in Northampton producing fake tirzepatide pens, and across 2025 around 20 million doses of illegally traded weight-loss medicines worth roughly £45m were seized. Some fake pens have contained insulin, a risk that could be life-threatening. The MHRA encourages anyone who encounters a suspect seller to report it at the Yellow Card scheme.

The pattern is consistent: sellers offering these medicines without a clinical assessment, at prices far below the market rate, or via social media DMs. A discount code attached to a prescription medicine from an unverifiable source is a red flag, not a deal. Wegovy sourced through a GPhC-registered pharmacy, on a valid UK prescription, comes from the licensed supply chain. There is no other safe version of this transaction.

If you want to understand more about what a legitimate Wegovy prescription involves, or explore the full picture of how semaglutide works before you decide, those are good places to start.

What happens after your prescription is approved at nume

Once a prescriber approves your treatment, your order is prepared and dispatched the same day if you placed it before 12pm. It arrives the next working day via DPD, tracked to your door, in a plain box with nothing on the outside to indicate what's inside. The pen itself (a pre-filled injector) comes with a Patient Information Leaflet that covers storage, injection technique and what to watch for. Keep it in the fridge at 2–8°C and read the leaflet; your prescriber and our aftercare team are available seven days a week for anything that comes up.

Every repeat order at nume is clinically re-reviewed before dispatch. There are no subscriptions, no automatic renewals. If you have questions about the process before committing, our FAQs cover the most common ones, or you can reach the team directly via our contact page.
