Weight Loss Injections in Stoke-on-Trent: What You Need to Do Next

Step 1: Understand which injections are licensed and why the prescription step exists

Two injectable medicines are licensed in the UK specifically for weight management: Mounjaro, which contains tirzepatide and is made by Eli Lilly, and Wegovy, which contains semaglutide and is made by Novo Nordisk. They work differently at the receptor level (Mounjaro activates two gut-hormone pathways (GIP and GLP-1), while Wegovy targets one (GLP-1)) but both reduce appetite, slow how quickly food leaves the stomach, and help people eat less without the constant mental effort of calorie-counting.

The prescription requirement isn't a bureaucratic hurdle. These medicines affect blood sugar, heart rate, digestion and, in some cases, absorption of other medicines including the oral contraceptive pill. A prescriber reviews your BMI, your existing conditions, any medicines you take and your goals before deciding whether treatment is appropriate. That clinical assessment is what keeps you safe, not just a tick-box exercise. If you'd like a broader picture of the different weight loss injections available and how they compare to one another, that page covers the licensed options in detail.

Starting doses are low on purpose. Mounjaro begins at 2.5 mg; the dose is moved up gradually by your prescriber as your body settles, typically in four-week intervals. Wegovy follows a similar stepwise escalation. The early weeks are about adjustment, not results, a point that trips up a lot of people who expect dramatic changes in week one.

Step 2: Check whether NHS access is realistic for you right now

NHS prescribing of tirzepatide (Mounjaro) is expanding in phases under NICE guidance, but the criteria are strict. As of summer 2026, the NHS is treating adults with a BMI of 40 or above who have four or more specific weight-related conditions, high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease or type 2 diabetes. A second cohort covering BMI 35–39.9 with four or more of those conditions began in June 2026. Even then, availability depends on whether your GP practice has signed up, and wraparound diet and activity support is a mandatory part of the programme. Wegovy on the NHS is dispensed through specialist weight management services, where waiting lists in many areas run to months or longer. For anyone who doesn't meet the current NHS thresholds (or simply can't afford to wait) private treatment through a regulated pharmacy is the practical alternative. The treatment overview page explains both routes clearly.

One quick check worth doing before you go further: visit the GPhC pharmacy register and search any online pharmacy you're considering. It takes under a minute and tells you immediately whether the pharmacy is legally registered to dispense prescription medicines. If it isn't listed, walk away.

Step 3: Know the side-effect picture before you start

The side effects of weight loss injections are mostly gastrointestinal, particularly in the early weeks, with nausea the most commonly reported, alongside loose stools, constipation, reflux and tiredness that most people find settle after the first few weeks, especially if they eat smaller portions and avoid very fatty or rich meals. Injection-site reactions (mild redness or itching) can also occur and usually resolve quickly.

A small number of more serious effects require prompt attention. In January 2026, the MHRA issued a Drug Safety Update reminding patients and clinicians that acute pancreatitis is a known, infrequent but serious risk with GLP-1 medicines. Severe stomach pain that spreads towards the back (with or without vomiting) warrants same-day medical attention, not a wait-and-see approach. Gallbladder problems and symptoms of dehydration following prolonged vomiting or diarrhoea also need a GP or urgent care call. The MHRA Yellow Card scheme lets patients report any suspected reaction directly, which contributes to ongoing national safety monitoring.

Women taking the oral contraceptive pill should know that tirzepatide specifically can reduce how well the pill is absorbed. An additional non-oral method of contraception (such as condoms) is advised for the first four weeks of treatment and for four weeks after each dose increase. Your prescriber will go through this with you before treatment begins.

Step 4: What a responsible private service actually looks like

Access to these medicines varies enormously in quality. A legitimate service will verify your identity with photo ID, confirm your weight through live video rather than taking your word for it, notify your GP in line with GPhC guidance, and have a named prescriber (a real clinician, not an algorithm) read your answers before approving anything. Repeat orders should involve a fresh clinical check, not automatic renewal. Aftercare support should be available if side effects arise mid-treatment. You can read more about how nume works and the clinical team behind every consultation.

For people in Stoke-on-Trent researching the different kinds of weight loss injections currently available, the options and the clinical differences between them are worth understanding before making a decision. Once you're ready to talk it through with a prescriber, a free consultation is the starting point, your answers are reviewed the same day, and if treatment is clinically appropriate, your prescription is issued and your pen dispatched the same day by tracked next-working-day delivery. Weight loss injections don't suit everyone, and a good service will tell you that plainly.

If you have questions about eligibility or the process, the FAQs page covers the most common ones, and you can also browse the current weight loss injections we offer to see exactly what is available before you begin. When you're ready, start your free consultation and a GPhC-registered prescriber will review your case the same day.
