How weight loss injections are prescribed through national health services
Prescription-only weight loss injections work by acting on appetite-regulating pathways in the body. Wegovy contains semaglutide, a GLP-1 receptor agonist, while Mounjaro contains tirzepatide, which acts on both GLP-1 and GIP receptors. Both are given as once-weekly subcutaneous injections using pre-filled pens, and dosing is started low before being adjusted over time by a prescriber.
Access through public healthcare systems
In some countries, including the UK, these medicines may be available through a national health service under specific clinical criteria — typically related to body mass index (BMI) and the presence of at least one weight-related health condition. Whether someone qualifies is a decision made entirely by their prescriber, based on their individual health history. If you are wondering who can get weight loss jabs through a national health service, your prescriber or doctor is the right person to advise you.
What the injection involves
These medicines are injected once a week, typically into the abdomen, outer thigh, or upper arm. Rotating the injection site each week is generally recommended to reduce the chance of skin reactions at any one spot. Your prescriber or the patient information leaflet supplied with your medicine will outline the sites suitable for you. For a broader overview, see our guide to weight loss injections and how they work.
If you experience any side effects — particularly anything severe or persistent — contact your healthcare professional promptly. Any suspected side effects should also be reported to your national reporting scheme (such as the UK's Yellow Card scheme or the equivalent in your country).

How GLP Trackr supports your injection routine
Once you are prescribed a weight loss injection, one of the most practical challenges is keeping on top of your weekly schedule — remembering which site you injected last time, when your next dose is due, and how your body is responding week to week.
Injection-site tracking and rotation
GLP Trackr's injection-site tracking feature lets you log each injection — the site used (abdomen, thigh, or upper arm), the date, and the dose strength. The app keeps a rotation history so it can suggest your next site automatically, taking the guesswork out of a habit you need to sustain for months. This is especially useful in the early weeks when the routine is still being established.
Dose logging and reminders
Alongside site tracking, the app logs every dose with its date and strength, giving you a clear record you can refer back to — or bring to a prescriber appointment. Gentle weekly reminders mean a dose is less likely to slip by unnoticed. You can also find information about accessing weight loss jabs through pharmacies and what to consider once you have your prescription.
For a wider look at everything involved in a weight loss injection journey, the weight loss jabs overview covers the key topics in one place.
GLP Trackr is a tracking companion — it records your journey and helps you spot patterns to discuss with your prescriber. It is not a substitute for their clinical guidance, and any questions about your dose, eligibility, or treatment should always go to your healthcare professional.

Frequently asked questions.
In some countries, including the UK, weight loss injections such as Wegovy or Mounjaro may be available through a national health service, but eligibility depends on individual clinical criteria. Your prescriber or doctor is the right person to assess whether you qualify.
Wegovy (semaglutide) and Mounjaro (tirzepatide) act on appetite-regulating pathways, commonly reducing hunger and increasing feelings of fullness. They are given as once-weekly injections using pre-filled pens, with doses started low and adjusted by a prescriber over time.
Rotating injection sites each week is generally recommended to help reduce skin reactions at any one spot. Common sites include the abdomen, outer thigh, and upper arm. Your patient information leaflet and prescriber will advise on the most suitable approach for you.
GLP Trackr lets you log each injection — recording the site, date, and dose — and tracks your rotation history to suggest your next site. Weekly dose reminders help keep your schedule on track, and the log can be a useful reference to bring to prescriber appointments.
If you experience side effects, particularly anything severe or persistent, contact your healthcare professional promptly. You should also report suspected side effects to your national reporting scheme, such as the UK's Yellow Card scheme or the equivalent where you live.
