Getting weight loss injections without going through your GP

You've looked at the NHS route and realised it's not straightforward

For many people, this is exactly where it starts. You've read about Mounjaro or Wegovy, perhaps heard about it from a friend, and then discovered that NHS access follows a phased rollout: currently limited to those with a BMI of 40 or above and four or more qualifying conditions, delivered through specific services with waiting lists attached. If you don't meet those criteria yet, or simply can't wait, the private route feels like the logical next step.

There's a misconception worth laying to rest here: some people assume that going private means bypassing proper medical oversight. It doesn't. A private prescription for a weight management injection requires the same clinical decision-making as an NHS one. What it skips is the queue, the referral letter, and the postcode lottery. A GP can prescribe weight loss injections privately or via NHS pathways, but so can an independent prescriber working for a regulated pharmacy, provided they hold the right qualifications.

At nume, every consultation is read and decided on personally by a GPhC-registered Independent Prescriber. A real clinician reviews your information the same day, not software, not a template response. They check your BMI, your medical history, any medicines you're already taking, and whether the treatment you're considering is appropriate for you. Only then is a prescription issued. The NHS recommends that your GP be kept informed when you start treatment of this kind, and our prescribers follow that guidance as a standard part of the process.

What happens if you decide not to contact your GP at all

You have no legal obligation to involve your GP when accessing private healthcare. Many people choose not to, for straightforward reasons: they prefer to keep things separate, their relationship with their GP practice is limited, or they simply want to move quickly. All of that is your right.

The practical considerations are worth knowing, though. Some medicines interact with others, and a prescriber assessing you privately won't automatically have access to your full GP record. That's why a thorough online consultation matters: if you're on anticoagulants, certain antidepressants, or any other medicines, you'll be asked about them. Tirzepatide in particular affects the absorption of oral contraceptives during the first four weeks of treatment and for four weeks after each dose increase, so anyone taking the pill will need to use an additional non-oral method during those windows. NHS England's guidance on weight management injections sets out these interaction considerations clearly and is worth a read before you start.

What the private prescription process looks like in practice

You complete a clinical questionnaire online. At a regulated service, that includes photo ID verification and a live video weight check, so the prescriber is working from verified data rather than self-reported figures. Your answers go to a prescriber's desk the same day. If you're approved, treatment is dispensed and dispatched, typically arriving the following working day via tracked delivery.

The medicines involved (Mounjaro and Wegovy) begin at low tolerability doses and are titrated upward over several months. This isn't something you manage on your own: before any dose change, a prescriber should review your progress and current health. If you're wondering whether you can access weight loss injections without any GP contact at all, there's a dedicated page that explains how that works and what the clinical process involves. Reputable private services build that repeat clinical review into the process rather than treating it as optional.

Knowing how much weight loss injections cost privately is a fair question at this stage. Prices vary by medicine and dose; legitimate private prescriptions include the clinical assessment and dispensing, not just the pen itself. The NHS patient information for tirzepatide is also a useful read on what the medicine actually is and how it works, separate from any commercial context.

When to check eligibility and what to expect

The licensed criteria for both Mounjaro and Wegovy are 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. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. A prescriber assesses the whole picture: BMI is a starting point, not a guarantee either way.

If you have questions that go beyond eligibility (side effects, what the injections involve practically, what to do if you miss a dose) the weight loss injections FAQ page covers those in detail, and our support team is available seven days a week. For a broader look at the medicines available through the private route, the treatment overview is the natural starting point.
