Can GPs Prescribe Wegovy, and What Are the Rules?

The common myth: that GPs simply can't prescribe Wegovy

Ask around and you'll hear people say their GP told them Wegovy isn't something they can prescribe. That's often true in practice, but it isn't because GPs lack the authority to prescribe semaglutide. The real constraint is commissioning. Under NICE technology appraisal TA875, NHS Wegovy is recommended only when used within a specialist weight management service offering multidisciplinary support, think dietitian input, behavioural coaching, structured monitoring. Most GP practices aren't commissioned to run that kind of service, so they can't offer Wegovy on the NHS, full stop. It isn't the GP refusing; it's that their practice hasn't been funded to provide what the NICE guidance requires.

That distinction matters. A GP who tells you they can't prescribe Wegovy is usually telling you the truth about the NHS side, not making a statement about private prescribing or about their clinical competence. The two pathways operate under completely different rules.

One other detail worth knowing: for NHS access, NICE TA875 specifies the treatment is for a maximum of two years, for adults with a BMI of 35 or above and at least one weight-related condition, with lower thresholds applying for some ethnic backgrounds. If you haven't lost at least 5% of your starting weight after six months on the maintenance dose, continuing would be reviewed. What the NHS Wegovy pathway actually involves is worth reading if you're weighing up the options.

What private prescribing changes for patients

Outside the NHS, the picture is different. Any appropriately qualified prescriber (a GP in private practice, a specialist, or a GPhC-registered Independent Prescriber working at a regulated online pharmacy) can issue a private prescription for Wegovy if the clinical assessment supports it. There's no commissioning requirement, no referral letter, no waiting list for a specialist service. The prescriber still makes the call; you still need a proper clinical review. But the route to that review is much more direct.

This is the route that regulated online pharmacies offer. At nume, every consultation is read by a GPhC-registered Independent Prescriber (a real clinician, not automated software) on the same day it's submitted. Identity and weight are verified on a live video call. If treatment is clinically appropriate and the order comes in before midday on a weekday, it's dispatched the same day and delivered free the next working day by DPD, in plain packaging. The cost of private Wegovy treatment is worth checking separately, since private pricing includes the prescription and clinical review in one transparent fee.

One practical aside: timing matters more than people expect. Orders placed on a Monday before the school run are typically the smoothest, payday orders in the middle of the month or orders placed just before a bank holiday are worth factoring into your delivery expectations.

The NHS is expanding access, but slowly (and Wegovy's route is still specialist-led

From April 2026, a new NHS primary care contract allows some GP practices to prescribe tirzepatide (Mounjaro) for weight management) which is genuinely new territory for GP-led NHS prescribing of weight-loss injections. You can read more about how NHS prescribing of weight-loss medicines works and what it means for patients. But Wegovy's NHS pathway hasn't shifted in the same way: semaglutide for weight loss remains routed through specialist services under TA875, so the GP commissioning gap described above still applies for most practices.

That said, the NHS landscape for weight management is moving faster than it has in years, driven partly by NICE guidance and partly by strong clinical trial evidence. NHS England's guidance on weight management injections is the clearest single source for what's commissioned where. If your GP practice has joined the new contract for tirzepatide prescribing, it's worth asking; if it hasn't, and you're waiting on a Wegovy referral, private prescribing through a regulated service remains the faster alternative for eligible adults.

Eligibility for private Wegovy follows the licensed indication: adults with a BMI of 30 or above, or 27 to 29.9 with at least one weight-related condition such as high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. BMI alone doesn't determine the outcome, the prescriber looks at the whole clinical picture. You can find a fuller breakdown on the Wegovy treatment page.

How to get a Wegovy prescription without a GP referral

If your GP practice isn't commissioned for NHS Wegovy and you'd rather not wait for a specialist referral, private prescribing is the legal, regulated route. The process at a GPhC-registered online pharmacy is straightforward: complete a medical questionnaire, have your identity and weight verified on a brief video call, and a prescriber reviews everything the same day. If they're satisfied it's clinically appropriate, a prescription is issued and treatment is dispatched. The whole consultation is free, as is the prescription, delivery and ongoing clinical support. Details of how Wegovy prescriptions are issued through regulated services explain the process in more depth.

If you've been searching for information on how to obtain Wegovy, it's worth being clear about one thing: any seller offering semaglutide or other GLP-1 weight-loss medicines without a prescription should be avoided. The MHRA has seized large quantities of fake pens from unverified online sources, some containing dangerous substances. Check any pharmacy you use on the GPhC register, that verification takes under a minute and tells you immediately whether you're dealing with a regulated dispensing service.
