Mounjaro on a Private Prescription: What Are the Typical Criteria?

Mounjaro is a prescription-only injectable medicine containing tirzepatide, a dual GIP and GLP-1 receptor agonist. Because it is a prescription-only medicine, no private clinic or prescriber can supply it without a clinical assessment. That assessment will differ from one service to another, but there are common factors most prescribers consider.

Body weight and BMI thresholds

Many private prescribers use BMI as one starting point. Commonly, a BMI of 30 or above — or a BMI of 27 or above alongside a weight-related health condition — is referenced as a threshold. However, your prescriber may apply different criteria based on clinical judgement, ethnicity-adjusted thresholds, or local guidance. These are indicative benchmarks, not universal rules.

Weight-related health conditions

Conditions such as type 2 diabetes, high blood pressure, sleep apnoea, or raised cholesterol are often factored in. Their presence may make a prescriber more likely to consider Mounjaro appropriate for you, though suitability is always individual.

Medical history and contraindications

Prescribers will ask about your full medical history. Certain conditions — including a personal or family history of specific thyroid tumours or pancreatitis — are contraindications listed in the product information. Your prescriber will screen for these. For a detailed overview of the medicine's own criteria, the electronic Medicines Compendium (eMC) holds the full Mounjaro prescribing information.

How private criteria compare to other access routes

If you are curious how private prescribing criteria compare to other routes, or how criteria differ for other medicines, it is worth reading about what prescribers typically look for when considering Wegovy, or exploring the broader topic of Mounjaro and how it is used. You may also find it useful to compare notes on accessing Wegovy privately if you have been considering both options.

What private prescribers assess can differ meaningfully from publicly funded criteria in any given country. Always ask your clinic what their specific eligibility requirements are before booking a consultation.

Once you have been prescribed Mounjaro and have started your injections, keeping an accurate record of your progress becomes genuinely useful — both for your own understanding and for conversations with your prescriber.

GLP Trackr's dose and injection logging feature lets you record every shot — the date, dose strength, and injection site — so you always have a clear history to refer back to. Over time, this builds into a timeline your prescriber can actually use. There is even a built-in doctor report feature that compiles your logged data into a summary you can bring to a follow-up appointment, making those check-ins more productive.

Alongside dose tracking, the app's side-effect log lets you note how you feel after each injection. Spotting patterns — whether a particular dose stage tends to bring more nausea, or energy dips on certain days — is much easier when it is all written down rather than trying to recall it weeks later.

Always follow your prescriber's guidance on dose stages and any changes to your schedule. If you have questions about whether Mounjaro is right for you, or about adjusting your treatment, those decisions belong with your prescriber or doctor — GLP Trackr records your journey and helps you discuss it, but it is not a substitute for their advice.
