Who Can Prescribe Weight Loss Injections?

Because Mounjaro and Wegovy are prescription-only medicines, only professionals who hold the legal authority to prescribe in their country can issue them. The exact rules vary between countries, but the following categories of clinician are typically involved.

Doctors

In most countries, a licensed medical doctor — whether a general practitioner or a specialist such as an endocrinologist or obesity medicine physician — is legally authorised to prescribe these medicines. Your doctor will review your medical history, current medications, and whether the medicine is appropriate for you before prescribing. They do not prescribe them to everyone who asks; clinical eligibility criteria apply, and your doctor is the right person to discuss those with you.

Independent prescriber nurses and pharmacists

In a number of countries, certain registered nurses and pharmacists who have completed an independent prescribing qualification are also legally permitted to prescribe prescription-only medicines, including weight loss injections. In the UK, for example, independent prescriber pharmacists and nurse prescribers operate under this framework — but equivalent roles exist in various forms worldwide. Whether a pharmacist at a counter can hand over these medicines without a prescription is a different question: a standard dispensing pharmacist cannot prescribe, but an independent prescriber pharmacist can, provided they have completed the relevant qualification.

Other qualified prescribers

Some countries permit other regulated health professionals — such as dietitians, physiotherapists, or paramedics with prescribing qualifications — to prescribe within defined practice areas. Whether weight loss injections fall within their prescribing scope depends on local regulation. When in doubt, the safest starting point is your own doctor or a registered specialist clinic.

What prescribers cannot do

No online quiz, chatbot, or self-assessment tool constitutes a legitimate prescription. A legal prescription requires a qualified prescriber to conduct an appropriate clinical assessment of you as an individual. If you are unsure whether a prescription you have received was issued lawfully, your national medicines regulator or professional healthcare body is the place to check.

For a broader overview of how these medicines fit into a weight management journey, see our guide to weight loss injections. If you are researching the cost side of things, our pages on weight loss injection prices and finding well-priced weight loss injections cover what to be aware of — though GLP Trackr does not sell or source medication.

Once your prescriber has assessed you and issued a prescription, the day-to-day management of your treatment is where GLP Trackr comes in. The app is built specifically for people already taking Mounjaro or Wegovy — not a prescribing service, but a companion that helps you stay on top of every injection.

The most immediately useful feature for a new user is injection-site tracking and rotation. Each time you inject, you log the site — abdomen, thigh, or upper arm — and the app keeps a history of your rotation so it can suggest where to inject next. Consistent rotation is something your prescriber will likely mention; the app makes it automatic rather than something you have to remember yourself.

Alongside that, dose and schedule logging means every injection is recorded with its date, time, and dose strength. If you ever need to check when you last injected, or want to bring a clear record to a prescriber appointment, it is all in one place. Dose reminders help make sure a weekly injection does not quietly slip past a busy week.

GLP Trackr is free to try for 7 days and available on the App Store and Google Play. Log your first injection, set up your rotation tracker, and let the app handle the admin of your treatment so you can focus on the journey itself.

GLP Trackr is a tracking app, not a prescriber or medical service. Any questions about whether these medicines are right for you, or about your dose, should always go to your own prescriber or doctor — they know your full clinical picture.
