NHS Mounjaro Criteria: What Prescribers Generally Look For

Mounjaro is a prescription-only medicine containing tirzepatide, a dual GIP and GLP-1 receptor agonist. Because it is prescription-only, a qualified prescriber must assess suitability before it can be dispensed — no criteria checklist can replace that clinical judgement.

What prescribers typically consider

While criteria vary between healthcare systems and individual clinical settings, prescribers commonly consider factors such as:

• Body mass index (BMI) — many prescribing frameworks set a minimum BMI threshold, sometimes adjusted for certain ethnic backgrounds where health risks occur at lower BMI values
• Weight-related health conditions — the presence of conditions such as type 2 diabetes, high blood pressure, or raised cholesterol may affect eligibility in some settings
• Previous attempts at weight management — some pathways ask whether diet, activity, and behavioural support have already been tried
• Contraindications — certain medical histories (for example, a personal or family history of specific thyroid conditions, or a history of pancreatitis) may affect whether Mounjaro is appropriate

How criteria are applied in practice

In the UK, prescribing guidance has been developed by bodies including NHS England, and specialist weight management services have their own referral pathways. Criteria can change as guidance is updated, so checking directly with your prescriber or a registered healthcare service in your country is always the most accurate route. For a broader look at how access to Mounjaro is structured, see our overview of Mounjaro and NHS access, or explore related guidance on Mounjaro NHS criteria in more detail and what the Mounjaro on NHS criteria cover.

According to NHS guidance, Mounjaro carries a black triangle (▼) designation, meaning it is subject to additional monitoring. If you experience side effects, your prescriber can advise you on reporting these through your national scheme (such as the UK's Yellow Card scheme or the equivalent in your country).

Once you are on Mounjaro, the focus shifts from qualifying to making the most of your treatment — and that is exactly where GLP Trackr is built to help.

The most immediately useful feature for people in the early stages of treatment is dose logging. Every weekly injection can be recorded — the date, the dose strength, and the injection site — so you always know where you are in your schedule and can bring a clear record to your next prescriber appointment. The app's injection-site rotation tracker also suggests your next site automatically, removing one more thing to remember.

Over time, the side-effect and symptom log lets you note how you feel after each dose. Spotting patterns — for example, whether certain symptoms ease after a dose increase, or cluster on particular days — gives you genuinely useful information to share with your prescriber at reviews. You can even generate a summary report from within the app to bring to those appointments.

For questions about whether you meet any particular prescribing criteria, or what the criteria mean for your situation, always speak with your prescriber or doctor — they are the only ones who can give you a personalised answer. GLP Trackr provides tracking and information support; it is not a clinical service and does not determine eligibility. You can also find broader context on Mounjaro cost and access considerations for further background.

If you are already prescribed and want a single place to stay on top of your doses, track how you feel, and build a record of your progress, give GLP Trackr a try — it is available free on the App Store and Google Play, with a 7-day trial so you can explore everything before committing.
