Mounjaro (tirzepatide) is a prescription-only weight loss injection that has generated significant interest in the UK since its MHRA approval for chronic weight management. For anyone wondering whether they qualify, the answer depends on a combination of your BMI, any existing health conditions, and which route, NHS or private, you are able to access. This guide sets out the eligibility criteria clearly and explains how to get started.
Is Mounjaro Available in the UK?
Yes. Mounjaro is available in the UK on prescription. It received MHRA approval for chronic weight management in adults in 2023 and has been available through both NHS specialist pathways and private prescription routes since then.
Mounjaro on prescription in the UK is not available over the counter and cannot be purchased without a valid prescription from a qualified prescriber. A clinical assessment confirming your eligibility is required before any prescription is issued, regardless of whether you are accessing it through the NHS or privately.
What Are the Mounjaro Eligibility Criteria?
The licensed Mounjaro criteria for weight management in the UK are based on body mass index (BMI) and, in some cases, the presence of at least one weight-related health condition. These criteria apply whether you are pursuing NHS or private access.
Mounjaro BMI Requirements
- BMI of 30 kg/m² or above — meets the primary obesity threshold for eligibility
- BMI of 27 kg/m² or above — eligible when accompanied by at least one weight-related health condition (see below)
These BMI thresholds are those set out in the Mounjaro summary of product characteristics. For patients from certain ethnic backgrounds, particularly those of South Asian, Chinese, or Black African heritage, lower BMI thresholds may be clinically appropriate given the different relationship between BMI and metabolic risk in these populations. Discuss this with your prescriber.
Weight-Related Conditions That May Qualify at BMI 27+
- Type 2 diabetes mellitus
- High blood pressure (hypertension)
- High cholesterol or raised triglycerides (dyslipidaemia)
- Obstructive sleep apnoea
- Cardiovascular disease (including history of heart attack or stroke)
- Non-alcoholic fatty liver disease
A prescriber will assess your full medical history to determine whether your weight-related condition qualifies alongside your BMI.
Who Cannot Get Mounjaro?
Even where BMI criteria are met, Mounjaro is not appropriate for everyone. It is contraindicated or requires extra caution for people who:
- Are pregnant, planning a pregnancy, or breastfeeding
- Have a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- Have a history of pancreatitis
- Have severe gastrointestinal disease
- Have a known hypersensitivity to tirzepatide or any component of the product
A thorough pre-prescription consultation will identify any contraindications before treatment is offered.
Is Mounjaro Available on the NHS?
Mounjaro is available on the NHS, but access is currently highly restricted. NICE Technology Appraisal guidance (TA1026) recommends tirzepatide for use within NHS specialist weight management services, subject to specific criteria including attendance at a specialist tier 3 or tier 4 service, a BMI of 35 or above (or 30+ in certain groups), and in conjunction with a managed care programme.
In practice, this means that the vast majority of people who meet the basic licensed eligibility criteria cannot currently access Mounjaro through their GP or a standard NHS pathway. NHS provision is limited to those enrolled in specialist programmes, and waiting times for these services are often significant.
For most people who qualify on the licensed criteria, a private Mounjaro prescription is the more accessible route at this time.
How Does a Private Mounjaro Prescription Work?
A private Mounjaro prescription can be obtained through a registered pharmacy or private prescribing clinic. The process involves:
- A clinical assessment with a qualified prescriber, in person or via a regulated online consultation, to confirm you meet the Mounjaro eligibility criteria
- A review of your medical history, current medications, and any contraindications
- A prescription being issued if you are deemed eligible, which can then be dispensed at a registered pharmacy
- Ongoing clinical oversight throughout treatment, including regular check-ins to monitor progress and manage any side effects
Private prescribing does not bypass the clinical assessment. A legitimate private prescription for Mounjaro requires the same due diligence as an NHS one. Be cautious of any service that issues a prescription without a proper consultation.
