Can you get weight loss injections on prescription in the UK?

What the prescription requirement actually means for you

There's a misconception worth clearing up gently: some people assume that online pharmacies are a way around the prescription process. They're not, or rather, the good ones aren't. A GPhC-registered pharmacy is legally required to obtain a valid prescription from a qualified prescriber before dispensing Mounjaro or Wegovy. What changes with a reputable online service is convenience and speed, not the clinical rigour.

A prescriber (not a form, not software) reviews your consultation to decide whether treatment is appropriate. At nume, that review is carried out by a GPhC-registered Independent Prescriber, personally, on the day you submit. If you want to understand exactly why a prescription is required for these medicines, the clinical reasoning is worth reading.

The prescription requirement exists for good reasons. These are powerful medicines that affect appetite, gastric emptying, and blood sugar regulation. A prescriber needs to know your full medical history, current medicines, BMI, and health conditions before deciding which treatment, if any, is right for you. That assessment protects you, particularly given the rise in counterfeit pens sold online without any clinical check at all, which the MHRA has warned about repeatedly.

NHS prescription: who qualifies right now

The NHS route for weight loss injections is real, but access is tightly phased. NHS availability for tirzepatide (Mounjaro) is currently limited under NICE guidance to adults with a BMI of 40 or above alongside four or more qualifying conditions from a defined list, high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease, or type 2 diabetes. A second cohort, covering BMI 35–39.9 with the same four conditions, opened in June 2026. Thresholds are 2.5 kg/m² lower for some ethnic backgrounds under UK guidance.

Wegovy (semaglutide) is available on the NHS through specialist weight management services under NICE guidance TA875, but waiting lists at those services are commonly long. NHS England's overview of weight management injections sets out both medicines' current commissioning position clearly.

From April 2026, GP practices can prescribe under the new GP contract, but participation is optional and coverage varies by area. If you don't meet the current NHS thresholds, or you do but don't want to wait, a private prescription is the practical alternative for many people.

Private prescription: what the process looks like

A private prescription follows the same clinical logic, just faster and without the NHS eligibility gates. The licensed criteria for private prescribing broadly mirror the medicine's licence: adults with a BMI of 30 or above, or 27 or above with at least one weight-related condition such as high blood pressure, high cholesterol, prediabetes, or obstructive sleep apnoea. BMI alone doesn't guarantee approval, the prescriber looks at the full picture.

At nume, the process runs like this: you complete a free consultation online, a prescriber reviews it the same day, and if treatment is clinically appropriate your order is dispatched the same day (for orders before midday, Monday to Friday) with free next-working-day DPD delivery. There's no subscription and no auto-renewal; every repeat order is reviewed again before dispatch.

If you're weighing up the private route, how to get a weight loss injection prescription covers the practical steps in detail. For those who'd prefer to handle the consultation entirely online, getting a prescription online explains what to expect and what legitimate providers must do to meet GPhC standards. You can verify any online pharmacy (including ours) on the GPhC pharmacy register; our premises registration number is 9012878.

Choosing: NHS vs private, and what to consider

The decision comes down to eligibility, timing, and what you want from ongoing support. If you meet the current NHS thresholds, exploring that route first makes sense, it's free at the point of care and comes with structured wraparound support. The honest caveat is that waiting times for specialist services can run to months, and GP prescribing under the new contract isn't yet available everywhere.

Private treatment through a regulated pharmacy offers a faster path for people who are clinically suitable but don't meet the NHS criteria, or who want to start now rather than wait. One transparent price covers consultation, prescription, treatment, and delivery (our treatment page shows current pricing) with no hidden extras and aftercare available seven days a week. NICE's appraisal of tirzepatide, TA1026, is a useful reference for the clinical evidence base behind the medicine.

What neither route offers is a shortcut around clinical assessment. For a frank look at why weight loss injections are not available without a prescription, and why that matters for your safety, that page is worth a read before making any decisions. If you're ready to find out whether you're suitable, start your free consultation and a prescriber will review your answers the same day.
