Who Is Eligible for Mounjaro? Key Criteria Explained

Because Mounjaro is a prescription-only medicine, the criteria used to determine eligibility vary depending on the healthcare system and the individual prescriber's clinical judgement. That said, prescribers typically consider a combination of the following factors when assessing whether tirzepatide is appropriate:

• Body mass index (BMI): In many clinical contexts, Mounjaro is considered for adults with a BMI of 30 kg/m² or above, or a lower BMI threshold (often around 27 kg/m²) where weight-related health conditions are also present.
• Weight-related health conditions: Conditions such as type 2 diabetes, high blood pressure, or obstructive sleep apnoea may form part of the eligibility picture alongside BMI.
• Previous weight-management attempts: Some pathways require evidence of engagement with diet, exercise, or other interventions before a GLP-1 medicine is considered.
• Contraindications and safety considerations: Mounjaro is not suitable for everyone. Pregnancy, a personal or family history of certain thyroid conditions, and other medical factors may affect suitability — your prescriber will have reviewed these.
• Age: Mounjaro is generally prescribed to adults; use in people under 18 would only occur under specific clinical direction.

In some publicly funded healthcare systems, such as the NHS in England, additional criteria apply — for example, referral through specialist weight-management services or specific commissioning criteria. However, eligibility routes differ by country and by whether access is through a public or private prescribing pathway. Your prescriber or doctor is the right person to clarify what applies in your situation.

For a more detailed breakdown of the specific criteria and how they are assessed, see our guide to understanding Mounjaro eligibility criteria, or explore the broader Mounjaro information hub for context on how tirzepatide works and what to expect on treatment.

It is also worth noting that Mounjaro is an injectable medicine — there is currently no approved oral tirzepatide formulation for weight management. If you have seen references to Mounjaro tablets, our page explains what that means and what the current position is.

Once eligibility has been confirmed by your prescriber and you are taking Mounjaro, the practical work of staying consistent and tracking your progress begins. GLP Trackr's daily check-in is designed for exactly this stage — a quick morning log of your weight, energy, mood, food noise, and sleep that builds into a meaningful picture of how your body is responding over time.

Alongside the daily check-in, the app's dose and injection logging keeps a clear record of every shot — date, dose strength, and injection site — so nothing gets lost across a weekly schedule. If you ever want a summary to bring to a prescriber appointment, the doctor report feature pulls your tracked data into a clear overview, making those conversations more informed and efficient.

GLP Trackr is free to try for 7 days on the App Store and Google Play — start building your tracking habit from your very first dose.

A note on safety: GLP Trackr is a tracking and journaling tool, not a medical service. Any questions about your eligibility, dose, or suitability for continued treatment should always go to your prescriber or doctor — they hold the full clinical picture. If you experience symptoms that feel severe or persistent, contact your healthcare professional promptly rather than relying on any app or website.
