Weight Loss Clinic Injections: What They Are, Who They're For, and How to Access Them

What actually happens at a weight loss injection clinic, and do you have to attend in person?

A question our prescribers hear most weeks is whether you have to travel to a physical clinic to get these injections. The short answer is no, not in the UK, not for this type of medicine. What matters legally and clinically is that a qualified, GPhC-registered prescriber reviews your health information, not where that review takes place. If you want to understand what a legitimate service looks like before deciding, our guide to weight loss injections clinics explains what to look for and how the process typically works. Some people prefer a face-to-face appointment; others find a regulated online service faster and more private.

Either way, the process is similar: you answer questions about your health, weight, medical history and any medicines you take. The prescriber checks whether you meet the licensed eligibility criteria, considers any contraindications, and makes a clinical decision. At a physical clinic you might sit in a waiting room first. Through a regulated online pharmacy like ours, your answers are reviewed the same day by a named prescriber, a real clinician reads them, not software. If you'd like to see who oversees clinical decisions at nume, our clinical team page explains that.

What neither route can do is promise approval in advance. Eligibility is a clinical judgement, and any service that guarantees access before assessing you is not operating to the standard you'd want for a prescription medicine.

Who qualifies for weight loss injections in the UK?

The licensed criteria are set by the medicines' regulators, not by individual clinics. For Mounjaro, UK licensing covers adults with a BMI of 30 or above, or a BMI from 27 upwards if at least one weight-related health condition is present, for example, high blood pressure, high cholesterol, prediabetes, type 2 diabetes, or obstructive sleep apnoea. Wegovy carries similar thresholds. The NHS eligibility picture is more restrictive: NICE's published guidance layers on additional conditions and, for now, limits NHS access to phased cohorts.

Private providers, including regulated online pharmacies, can work to the broader licensed criteria, which means some people who don't currently qualify for NHS treatment may still be suitable for private prescription. Lower BMI thresholds apply for some ethnic backgrounds under UK clinical guidance, your prescriber will factor this into their assessment.

BMI alone never seals the decision. A prescriber also considers your medication list, any history of pancreatitis, thyroid conditions, or certain gastrointestinal disorders, and whether you're pregnant, breastfeeding, or planning to conceive. If any of those apply, these medicines are not recommended. The same applies to anyone under 18, neither Mounjaro nor Wegovy is licensed for that age group.

If you're trying to find a weight loss injections clinic near you, it's worth understanding what a legitimate service looks like before you search, as the range of options varies considerably by location and provider.

What do the side effects of weight loss injections actually feel like day to day?

Both tirzepatide and semaglutide share a broadly similar side-effect profile, dominated by gastrointestinal symptoms. Nausea is the most commonly reported one; others include loose stools, constipation, indigestion, and occasionally vomiting. These effects tend to be most noticeable in the first few weeks of treatment or after a dose increase, and many people find they settle as the body adjusts.

This is part of why the dosing schedule for both medicines starts low (2.5mg for tirzepatide, 0.25mg for semaglutide) and increases gradually under prescriber oversight. The NHS's patient-level guide to tirzepatide on NHS.uk covers the side-effect list clearly and is worth reading before you start.

A few symptoms deserve prompt medical attention. Severe, persistent stomach pain that spreads to the back (with or without vomiting) could signal pancreatitis, which the MHRA flagged in a Drug Safety Update in January 2026 as an infrequent but serious risk with GLP-1 medicines. Symptoms of gallbladder problems, signs of a serious allergic reaction, or significant dehydration from prolonged vomiting or diarrhoea should also prompt you to get help quickly rather than wait for your next check-in. You can report any suspected side effect through the MHRA Yellow Card scheme.

Women taking oral contraceptives should know that tirzepatide may reduce pill absorption during the first four weeks of treatment and for four weeks after each dose increase. Your prescriber will advise on adding a barrier method during those windows.

Is a private weight loss injection clinic worth it compared with waiting for NHS treatment?

It depends on your situation, and there's no single right answer. NHS access to Mounjaro and Wegovy is expanding but remains tightly phased. As of mid-2026, Mounjaro on the NHS requires a BMI of 40 or above alongside multiple qualifying conditions, criteria that many people don't meet, even with genuine weight-related health concerns. Wegovy through NHS specialist services typically involves long waiting lists. If you'd like a fuller breakdown, getting weight loss injections on the NHS sets out the current pathway honestly.

Choosing a private clinic for weight loss injections means no referral, no waiting list, and a consultation that's reviewed the same day, though it also costs money: private prescriptions for these medicines run into the hundreds of pounds per month, and the right question to ask any provider is what the headline price actually includes. Some clinics charge separately for the consultation, the prescription, delivery, and any follow-up support. A price that looks lower upfront can end up costing more across a course of treatment.
