Who can prescribe semaglutide, and how does the process work?

Step 1, Understanding who holds prescribing authority for semaglutide

Semaglutide is classified as a Prescription-Only Medicine under the Human Medicines Regulations 2012. That means a clinician with full prescribing authority must review you and issue a prescription before a pharmacy can dispense it. In practice, three groups of registered professionals can do this.

First, NHS GPs. Your family doctor can prescribe Wegovy if you meet the eligibility criteria set out by NICE and NHS England. The question of whether your GP will prescribe semaglutide depends on local commissioning, practice policy, and whether you meet the threshold for a specialist referral, GP prescribing for weight management through the new GP contract only began rolling out from April 2026, and not every practice has opted in yet.

Second, hospital specialists and multidisciplinary teams in NHS weight-management services. NICE's guidance on semaglutide (TA875) specifies it should be used within a specialist weight-management service, so for many NHS patients the prescriber is a consultant or a clinical pharmacist attached to that team. You can read more about how that pathway works on our NHS prescribing for Wegovy page.

Third, GPhC-registered Independent Prescribers working in private practice or through regulated online pharmacies. This is the route most people asking this question are exploring, and it is entirely legal. An Independent Prescriber pharmacist has completed postgraduate clinical training and holds the same prescribing authority as a GP within their area of competence.

Step 2, What the prescribing consultation actually covers

Whoever issues the prescription, the clinical assessment follows a similar shape. The prescriber checks your BMI (the licensed threshold is 30 or above, or 27 or above alongside at least one weight-related condition such as high blood pressure, high cholesterol, or obstructive sleep apnoea). They review your medical history for contraindications, a personal or family history of medullary thyroid carcinoma or MEN2, for example, rules it out. They check your current medicines, because semaglutide slows gastric emptying and can affect how oral medicines are absorbed.

Women using oral contraceptives are advised to use an additional non-oral method of contraception during treatment, as noted in NHS England's guidance on weight-management injections. If you are pregnant, breastfeeding, or planning to conceive, semaglutide is not recommended. The prescriber also asks about your weight history and what you have tried before, because semaglutide is intended to work alongside a reduced-calorie diet and increased activity, not instead of them.

At a private pharmacy like nume, this consultation happens through a structured clinical questionnaire reviewed personally by a GPhC-registered Independent Prescriber on the same day. A real clinician reads your answers, not an automated system. Identity and current weight are verified too, so the prescriber is working from accurate information.

Step 3, Choosing between NHS and private prescribing

If you are wondering about GP prescribing for Wegovy specifically, the honest picture is this: NHS access exists, but eligibility criteria are strict (set by NICE TA875) and waiting lists for specialist services are long in most areas. For people who don't currently qualify for NHS treatment, or who would rather not wait, a private prescription through a regulated online pharmacy is the legal, well-established alternative.

Checking that any online pharmacy is legitimate takes about thirty seconds. The GPhC (General Pharmaceutical Council) publishes a public register at pharmacyregulation.org/registers, search by name or registration number and confirm the pharmacy is listed. Sellers offering semaglutide without a prescription, via social media, or with prices that seem implausibly low are not operating legally. The MHRA has made multiple public warnings about counterfeit weight-loss pens, some of which have caused hospitalisations. If the pharmacy you are looking at cannot be found on the GPhC register, that matters.

If you would like to understand the broader landscape of where to source treatment, the Wegovy sourcing guide covers this in more detail. For context on costs across private providers, the Wegovy private prescription page explains what a legitimate private prescription includes and what headline prices sometimes leave out.

Step 4, What happens after the prescription is issued

Once a prescriber has reviewed your consultation and approved treatment, the prescription is sent to the dispensing pharmacy. At nume, that is our own GPhC-registered pharmacy (registration 9012878, verifiable at pharmacyregulation.org). Medicines are sourced through the licensed UK supply chain. Orders placed before 12pm on a working day are dispatched the same day by DPD, tracked, next working day, plain unbranded packaging. The pen goes straight into the fridge door when it arrives, and that is the only storage step needed at your end.

Every repeat order goes through a fresh clinical review. The prescriber checks that your weight is responding appropriately, that any side effects are manageable, and that the dose is still right. This is not a formality, it is the mechanism that makes ongoing treatment safe. You can find an overview of how our clinical team approaches this on the clinical team profile.
