Who can prescribe semaglutide in the UK, and what does the process involve?

Which clinicians are legally allowed to prescribe semaglutide?

Semaglutide is a Prescription-Only Medicine regulated under the Human Medicines Regulations 2012, so the question of who can prescribe it has a precise legal answer. In England, Wales and Northern Ireland, prescribers authorised to write a valid semaglutide prescription include medical doctors (GPs and hospital specialists), dentists where clinically relevant, and (importantly for online services) nurses and pharmacists who hold an Independent Prescriber qualification registered with their professional body. A GPhC-registered Independent Prescriber at a regulated online pharmacy carries exactly the same legal authority as your GP to assess and prescribe.

What matters is that the prescriber personally reviews your clinical information before any prescription is issued. A checklist filled in by software and auto-approved is not a legal prescription; the clinician must exercise their own professional judgement. At nume, every consultation is read and decided by a named prescriber, not passed through an algorithm. If you want to understand more about which specific roles carry prescribing rights, our detailed guide to who can prescribe semaglutide covers the regulatory picture in full.

Scotland follows the same professional-registration framework, though NHS access thresholds differ, which is worth knowing if you are weighing up NHS and private routes.

What does a prescriber actually assess before approving semaglutide?

The clinical assessment for semaglutide is more thorough than a quick BMI check. A prescriber will want to know your current BMI (and the conditions associated with it), your medical history, any medicines you take that could interact, and whether there are contraindications that would make semaglutide unsuitable for you.

The licensed eligibility thresholds for Wegovy, as set out in its Summary of Product Characteristics and reflected in NICE's technology appraisal TA875, are a BMI of 30 or above, or 27 to 29.9 alongside at least one weight-related condition such as hypertension, dyslipidaemia, obstructive sleep apnoea, or type 2 diabetes. Lower BMI thresholds apply for some ethnic backgrounds under UK clinical guidance. Reaching the threshold is necessary but not sufficient on its own, your prescriber will also consider your history of pancreatitis, any active gallbladder disease, whether you are pregnant or breastfeeding, and whether you are under 18, since semaglutide is not licensed for those groups.

In practice, getting prescribed semaglutide through a regulated online service involves completing a structured health questionnaire, verifying your identity with photo ID, and confirming your weight on a video call, steps that replicate, and in some cases exceed, what an in-person appointment involves. A prescriber then reviews everything the same day.

Can my GP prescribe semaglutide, and is it available on the NHS?

Your GP can prescribe semaglutide, but whether they will depends on which medicine is being requested and under what circumstances. Wegovy (semaglutide for weight management) is available on the NHS, but access follows a phased rollout tied to strict eligibility criteria set by NHS England and NICE TA875. NHS prescribing of Wegovy is currently directed through specialist weight management services, and waiting lists are commonly long. From April 2026, some GP practices gained the ability to prescribe tirzepatide under a new GP contract, though participation is optional and coverage varies by area.

For Wegovy specifically, whether your GP will prescribe semaglutide depends partly on local commissioning, partly on whether you meet the current NHS thresholds, and partly on whether your practice has the capacity to manage a weight management pathway. Many people who are eligible in principle face a wait of months or longer.

A private prescription from a GPhC-registered Independent Prescriber is the alternative. It carries the same legal standing as an NHS prescription, uses the same licensed medicine from the authorised UK supply chain, and bypasses the waiting list. The cost is different, private semaglutide pricing varies by dose and provider, and typically includes consultation and dispensing fees when purchased through a regulated service. If you are curious about which pharmacies hold stock, availability across UK pharmacies shifts regularly, and it is worth checking before you commit to a provider.

What happens after a prescriber approves semaglutide?

Once a prescriber is satisfied that semaglutide is appropriate for you, they issue a prescription and the medicine is dispensed by a registered pharmacy. The NHS patient information for semaglutide gives a clear overview of how Wegovy is taken (once-weekly subcutaneous injection, starting at a low dose and titrated gradually) but the exact schedule that applies to you is set by your prescriber, not self-selected.

At nume, the process runs end to end in a single day for most patients. Submit your consultation before midday on a working day and, if your prescriber approves it as clinically suitable, your treatment is dispatched the same afternoon and arrives the next working day via DPD tracked delivery, in plain unbranded packaging. There are no subscriptions; every repeat order goes back to a prescriber for a fresh review before anything is sent. If you want to check your eligibility or speak to our clinical team, you can start a free consultation with no obligation.
