Is it safe to buy Wegovy online in the UK?

What the MHRA's enforcement record tells you about buying online

The MHRA has issued repeated public warnings about fake semaglutide pens circulating online and through social media. The scale is not trivial: enforcement action in 2025 alone saw roughly 20 million doses of illegally traded weight-loss medicines (worth around £45 million) seized. In October 2025, the MHRA raided the first illicit UK site manufacturing counterfeit tirzepatide pens. Earlier warnings flagged that some fake pens seized from online sellers contained insulin instead of semaglutide, causing hypoglycaemic episodes in people who had no idea what they were injecting.

A question our prescribers hear most weeks is whether a cheaper listing found on social media or via a generic pharmacy site is worth the risk. The honest answer is that a counterfeit pen has no clinical oversight behind it, no verified supply chain, and often no way to report a problem. The MHRA's Yellow Card scheme exists precisely so that patients can flag suspect sellers and adverse reactions, and it only works if the product came through a channel that can be traced.

The red flags to watch for: a seller offering Wegovy without requiring a prescriber's assessment; prices that sit well below the typical private market; discount codes attached to a prescription medicine; no verifiable UK pharmacy registration. Legitimate pharmacies do not need to lure you with vouchers. If something feels off, it probably is.

The only legal route to Wegovy in the UK, and how it works in practice

Wegovy (semaglutide) is a Prescription-Only Medicine under the Human Medicines Regulations 2012. That means a UK-licensed prescriber must assess your suitability and issue a prescription before any pharmacy can dispense it. There is no legal shortcut.

In practical terms, the process through a regulated online pharmacy like nume runs like this. You complete a detailed medical questionnaire. A GPhC-registered Independent Prescriber reviews your answers (same day) alongside your ID verification and a live video weight check. If the prescriber considers treatment clinically appropriate, a prescription is issued and your order is dispensed and dispatched. You can read more about what each step involves on our guide to getting Wegovy online.

Any pharmacy operating legally in the UK must be registered with the General Pharmaceutical Council. You can confirm a pharmacy's registration in under a minute: visit the GPhC's public register, search by name or registration number, and check that the entry is current and active. For reference, nume's GPhC premises registration is 9012878. If a pharmacy cannot be found on that register, do not use it.

Who is eligible, and what private access actually involves

The licensed eligibility criteria for Wegovy in private practice reflect the medicine's UK marketing authorisation: adults with a BMI of 30 or above, or 27 to 29.9 with at least one weight-related health condition such as high blood pressure, high cholesterol or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK clinical guidance. A BMI figure alone does not determine suitability, the prescriber weighs the full clinical picture, including your medical history and any medicines you already take.

Wegovy is not appropriate during pregnancy, breastfeeding or when trying to conceive. It is not licensed for use under 18. Certain medical histories (including a personal or family history of medullary thyroid carcinoma, or a history of pancreatitis) require careful prescriber assessment before treatment can be considered. The NHS semaglutide medicines page gives a plain-English summary of the key cautions and side effects worth reading before you start.

NHS access to Wegovy exists but is restricted to specialist weight management services under NICE guidance (TA875), and waiting lists can be long. Private treatment through a regulated online pharmacy is the route for people who meet the clinical criteria but are not in, or do not want to wait for, an NHS pathway. Explore what that looks like on our Wegovy treatment overview.

How to tell a genuinely safe online service from one that isn't

A safe online pharmacy does a few things that an unsafe one either cannot or will not. It asks detailed medical questions before any prescriber sees your case. It verifies who you are. It weighs up your history against the medicine's contraindications. It keeps a clinical record and follows up. And it tells its GP notification policy upfront, in line with GPhC guidance.

At nume, GP notification happens in line with GPhC standards, your Summary Care Record may be reviewed where appropriate, and transfer patients are asked to provide evidence of their current treatment and dose before any repeat is issued. That is not bureaucracy for its own sake, it is the infrastructure that makes prescribing at a distance safe. Our clinical team page sets out who reviews consultations and what their qualifications are, and you can read about our lead prescriber's background at our clinical team profile.

When you're ready to see whether Wegovy is clinically suitable for you, the right next step is a free consultation, reviewed by a prescriber, not a chatbot, the same day you submit it.
