Lemon Injection for Weight Loss Price: What Private Treatment Actually Costs in the UK

Step 1, Find out what the market really looks like (hedged, factual, no nasty surprises)

Pricing for the medicines most people call "lemon injections" is set per pen, with each pen covering four weekly doses. The cost climbs with the dose, because higher strengths contain more active medicine and are produced in smaller commercial volumes. Since Eli Lilly adjusted Mounjaro's UK list price in September 2025, the range across private providers has shifted noticeably: the lowest starting doses sit closer to £149 a month, while the highest dose runs up to around £375, with most providers sitting somewhere between those figures depending on dose and service model. If you want a clearer sense of how those figures break down, our guide to how much weight loss injections cost walks through what drives the variation and what to expect at each stage. One thing the headlines rarely say: at the starter dose, you're not yet at the therapeutic level. The first few months are about tolerability, not peak effect, so the price you see for the lowest dose isn't the whole-treatment price. That matters when you're budgeting.

Wegovy (semaglutide) tends to price similarly across the range, and a newer option is now available: oral semaglutide tablets, approved by the MHRA on 11 June 2026, offer a needle-free route for those who qualify. If you'd like to understand how the price of weight loss injections compares across these options, the weight-loss injections overview sets out how they compare on a practical level.

Step 2, Check what the headline price actually covers

This is where a lot of frustration comes from, and it's worth being direct about. A per-pen price on a website often excludes several things that are, in practice, unavoidable. Consultation fees are frequently charged separately. Prescription fees can add another layer. Delivery (which for a temperature-sensitive injectable is not trivial) may be billed per order. Aftercare, dose-review support, and access to a clinician when something unexpected happens are sometimes listed as premium add-ons or simply not mentioned at all.

Understanding the full weight loss injection price, including what is and is not covered by a given provider, is worth doing before you compare providers, because the question isn't just what the pen costs, it's what you're left dealing with on your own after you receive it. For anyone comparing Saxenda alongside these newer options, Saxenda's pricing context is covered separately, though it's worth noting that Saxenda is a different medicine (liraglutide) and the clinical picture differs.

NHS England's guidance on weight-management medicines is clear that these are not over-the-counter products: clinical oversight isn't an optional extra layered onto a commodity purchase, it's the entire framework that makes the treatment safe.

Step 3, Understand where nume sits on price, and why

We are deliberately not the cheapest. That's a choice, not an oversight. Cheapest isn't a race we entered, because the things that keep treatment safe cost money, and cutting them is what produces the rock-bottom listings.

At nume, one price covers the consultation, the prescription, the medicine, tracked next-working-day DPD delivery, and seven-day aftercare. There are no bolt-ons. Every repeat order is clinically reviewed again from scratch, by a GPhC-registered Independent Prescriber, before anything is dispatched. Our pharmacy is registered with the GPhC, you can verify that directly at the GPhC register (premises number 9012878). If you order before 12pm Monday to Friday and are clinically approved, your treatment goes out the same day.

Current treatment pricing is listed on the treatments page, we don't bury it. If you want to understand how that sits across the broader market, the guide to cost-effective weight-loss injection options gives an honest picture. And if you're wondering whether there's a cheaper deal hiding somewhere, read on.

Step 4, Why "cheapest" is the wrong test for a prescription medicine

If you've been searching for a discount code or a deal on these injections, you've probably noticed that some sites offer them. Here's the thing: these are Prescription-Only Medicines. The MHRA has seized around 20 million doses of illegally traded weight-loss medicines worth roughly £45 million, including counterfeit pens containing insulin rather than the stated drug. The first illegal UK manufacturing site producing counterfeit tirzepatide pens was raided in 2025. The pattern is consistent, sellers offering these medicines without a legitimate prescription, at prices well below market, through social media or unverified websites, represent a real physical danger.

A small saving on the pen price is not the right measure. The right measure is whether the prescriber is real, the pharmacy is GPhC-registered, and the medicine came through the licensed UK supply chain. You can report suspect sellers via the MHRA's Yellow Card scheme, it exists precisely for this.

We understand the frustration. These treatments aren't cheap, the NHS waiting lists are long, and it can feel like you're being asked to spend a lot of money with no guarantee of what you'll get. That feeling makes sense. It's why transparency about what's included matters more than advertising the lowest number. If you'd like to talk through what's right for your situation, the FAQs cover common questions, or you can start your free consultation and a prescriber will review your answers the same day.
