How to Get a Weight Loss Injection on the NHS

Because Mounjaro and Wegovy are prescription-only medicines, no one can obtain them without a prescriber confirming they are appropriate. Access through any publicly funded health service typically depends on specific eligibility criteria — such as BMI thresholds, the presence of weight-related health conditions, and whether other interventions have already been tried. These criteria vary by country, region, and the type of service involved, so what applies in one place will not necessarily apply in another.

Referral and specialist pathways

In many countries with publicly funded healthcare, weight management medicines are initially made available through specialist obesity or diabetes services rather than general primary care. A prescriber may refer someone to such a service if they meet the relevant criteria. The prescriber — whether a doctor, specialist, or other qualified clinician — will be the one to confirm eligibility and initiate any prescription.

Private prescription routes

Where publicly funded access is limited or subject to waiting times, some people choose to pursue a private prescription through a registered clinic or pharmacy service in their country. This is a separate route from any national health service and carries different cost and administrative considerations. Any decision about which route to pursue should be discussed with your prescriber or doctor.

If you are already prescribed one of these medicines and want to understand more about how weight loss injections are generally obtained, or the broader topic of getting started with a weight loss injection, those pages cover the process in more detail. You may also find it useful to read about whether you can get a weight loss injection through a publicly funded service and what criteria are commonly involved.

For a broader overview, the weight loss injections guide covers how these medicines work, what to expect, and how to track your journey once you are prescribed.

If you have already been prescribed a weight loss injection, staying consistent with your weekly schedule is one of the most important things you can do. GLP Trackr's injection-site tracking and rotation feature logs every injection — the site you used (abdomen, thigh, or upper arm), the date, and the dose strength — and then suggests where to inject next time, so rotation becomes automatic rather than something you have to remember yourself.

Alongside site rotation, the app's dose reminders mean you are far less likely to miss a weekly injection, and every logged dose builds a clear record you can refer back to or share with your prescriber at your next appointment.

If you experience any side effects after your injection — nausea, fatigue, or injection-site reactions, for example — the side-effect tracker lets you log how you feel and spot patterns over time, giving you something concrete to discuss with your healthcare team.

Always follow the guidance of your prescriber or doctor regarding your injection schedule, dose, and any symptoms you experience — they know your full medical history and are best placed to advise you. If you have concerns about a side effect or are unsure about any aspect of your treatment, contact your healthcare professional promptly rather than making changes on your own.
