Can I Use Mounjaro? What the Eligibility Criteria Actually Mean

You've looked up the criteria and you're not sure where you land

Picture this: you've found the NHS BMI page, done the maths, and you're sitting at 28.5 with a blood-pressure diagnosis from last year. You want a straight answer about whether Mounjaro is an option for you. The honest one is: probably yes, based on the licence, but a prescriber needs to confirm it.

Mounjaro is licensed in the UK for weight management in adults with a BMI of 30 or above, and in adults with a BMI between 27 and 29.9 who have at least one weight-related condition. Qualifying conditions include type 2 diabetes, hypertension, high cholesterol, obstructive sleep apnoea, prediabetes and osteoarthritis, among others. So a BMI of 28.5 with a confirmed hypertension diagnosis would, on paper, meet the threshold. You can use the BMI requirements for Mounjaro page to check the numbers in more detail.

There is an important adjustment for some ethnic backgrounds. UK clinical guidance sets lower BMI thresholds (typically 2.5 kg/m² below the standard figures) for people of South Asian, Chinese, Middle Eastern, Black African or African-Caribbean descent. A prescriber will apply this where relevant. If you are unsure whether your situation fits the full picture, the guide to who can use Mounjaro walks through eligibility in plain terms.

The NHS medicines page for tirzepatide sets out the patient-level picture clearly if you want a second reference point alongside this page.

The conditions that would stop a prescriber saying yes

Meeting the BMI threshold gets you to the table; it does not guarantee a prescription. Prescribers look at the whole clinical picture, and some findings close the door on Mounjaro regardless of weight.

Mounjaro is not licensed for use in pregnancy, and it is not recommended for anyone who is breastfeeding or actively trying to conceive. If you are planning a pregnancy, your prescriber will discuss stopping the medicine and an appropriate wash-out period. Under-18s are also excluded, the licence is for adults only.

A personal or family history of medullary thyroid carcinoma (a specific type of thyroid cancer) or a condition called MEN2 (multiple endocrine neoplasia type 2) means Mounjaro is contraindicated. A history of pancreatitis is another flag the prescriber will want to explore carefully before proceeding.

Certain medicines interact with Mounjaro in ways that require clinical judgement, particularly oral contraceptives. Women taking the pill should know that tirzepatide can reduce its absorption during the first four weeks of treatment and for four weeks after each dose increase; adding a non-oral method during those windows is the standard advice from NHS England. If you want the detail on a specific combination, the medicines and Mounjaro page covers common questions.

None of this is a reason to self-diagnose yourself out of eligibility. The consultation exists precisely to work through these points with a clinician.

What the NHS offers versus the private route

NICE recommended Mounjaro for NHS use in its technology appraisal TA1026, published in December 2024. The NHS criteria are considerably stricter than the licence: currently, access requires a BMI of 40 or above alongside four or more of five specified conditions (high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease and type 2 diabetes). A second cohort (BMI 35 to 39.9 with four or more conditions) opened in June 2026. Waiting lists exist, and every NHS patient must take part in a structured diet and activity support programme alongside treatment.

Private treatment through a regulated online pharmacy operates under the broader licence thresholds rather than the NICE NHS criteria, which is why people who do not meet the NHS criteria may still be clinically suitable for a private prescription. For a clearer comparison of routes, the weight-loss treatments overview lays out what each pathway involves.

If cost is part of your thinking, the Mounjaro price comparison page gives an honest picture of what private treatment costs in the UK and what to look for in a provider. That's worth reading before you decide anything.

What the nume consultation actually checks

At nume, every consultation is read personally by a GPhC-registered Independent Prescriber, a real clinician, same day. You submit your health information, and it lands on a prescriber's desk, not in a queue for automated software. Identity is verified with photo ID, and weight is confirmed on a short video call. If you submit before noon on a weekday and you are approved, your treatment leaves the same day by tracked DPD delivery, in plain packaging.

There is no subscription. Every repeat order goes through the same clinical review as the first. Our clinical team includes pharmacists and prescribers with specialist experience in weight management, and aftercare support runs seven days a week.

If you have been on Mounjaro elsewhere and want to transfer, you will need to provide evidence of your current dose and treatment history, that is standard clinical practice, not bureaucracy. Some people also ask whether they need to commit to a long course before starting, and the page on using Mounjaro for one month addresses that question directly. The taking Mounjaro page covers what to expect once treatment begins. For now, the clearest next step is to start your free consultation and let a prescriber review your situation properly.
