How prescribing criteria for Mounjaro generally work
Mounjaro is a prescription-only medicine containing tirzepatide, a dual GIP and GLP-1 receptor agonist. Wegovy (semaglutide) is similarly prescription-only. In many healthcare systems, access to these medicines through publicly funded routes — such as through the NHS in the UK — is governed by formal criteria set by health technology bodies and clinical commissioners.
What criteria typically include
While the specifics vary by country and healthcare system, publicly funded access criteria for GLP-1 medicines commonly consider factors such as:
- Body mass index (BMI) above a defined threshold, sometimes adjusted for certain ethnic backgrounds
- The presence of at least one weight-related condition (such as type 2 diabetes, high blood pressure, or raised cholesterol)
- Engagement with a structured weight management programme
- Previous treatment history and individual clinical circumstances
These criteria are set by clinical and commissioning bodies, not by individual clinicians acting alone, and they can change as new guidance is issued. For UK-specific detail, NHS guidance is the authoritative public source, though the criteria that apply to you personally depend on your local area and your own prescriber.
Criteria differ across healthcare systems
If you are outside the UK, the criteria your prescriber applies will reflect your own country's regulatory and funding framework. No single set of rules applies everywhere. Your prescriber or doctor is the right person to explain exactly which criteria apply in your case and what pathway is available to you.

Already prescribed? Here is where GLP Trackr helps
GLP Trackr is a companion app for people already taking Mounjaro or Wegovy — it does not sell, supply, or source medication, and it cannot tell you whether you qualify under any criteria. What it does do is help you make the most of the prescription you already have.
Stay consistent with dose logging and reminders
Once you are prescribed, consistency matters. GLP Trackr lets you log every weekly injection — recording the dose strength, date, and time — so you always know exactly where you are in your treatment schedule. Gentle reminders mean a dose is far less likely to slip your mind during a busy week.
Track your progress to bring to appointments
Many people find that preparing for prescriber appointments is much easier when they have clear data to hand. The app's built-in doctor report pulls together your weight trend, logged side effects, and dose history into a summary you can share — making those conversations more productive and helping your prescriber see the full picture of your journey.
For more on getting value from your treatment over time, our page on understanding the cost of Mounjaro explores what to consider as you plan your journey.
Any decision about whether you continue to meet prescribing criteria, or whether your dose or treatment should change, is one for your prescriber or doctor — they know your full history and the requirements that apply in your healthcare system.
If you are already on your GLP-1 journey and want one place to log doses, track progress, and prepare for appointments, GLP Trackr is free to get started. Download it on the App Store or Google Play and explore everything with a 7-day free trial.

Frequently asked questions.
In the UK, NHS access to Mounjaro is typically governed by criteria set by commissioning bodies, often including BMI thresholds, weight-related health conditions, and participation in a weight management programme. Exact criteria can vary by region and change over time — your prescriber or doctor is the best source for what applies to you.
Wegovy (semaglutide) and Mounjaro (tirzepatide) are both prescription-only medicines, and access through publicly funded routes like the NHS follows separately issued guidance for each. Your prescriber or doctor can tell you which criteria apply to the specific medicine you have been prescribed.
General information about access criteria is publicly available through sources such as NHS guidance, but whether you personally meet the criteria is a clinical judgement made by your prescriber, who will consider your full medical history and the requirements applicable in your area.
No. GLP Trackr is a tracking and journaling app for people already prescribed Mounjaro or Wegovy. It does not sell, supply, or source medication, and cannot advise on eligibility. For access questions, speak with your prescriber or doctor or contact a registered pharmacy in your country.
GLP Trackr helps you log every dose, track your weight and side effects, and build a progress summary to share at prescriber appointments. It is designed to support consistency and informed conversations with your healthcare team throughout your treatment journey.
