How to Get the Mounjaro Injection in the UK

NHS or private: the first fork in the road

Your first real decision is whether to pursue Mounjaro through the NHS or privately. Both routes lead to the same medicine, but they work very differently in practice.

On the NHS, tirzepatide is being phased in under strict eligibility thresholds, NICE's appraisal TA1026 currently limits access to adults with a BMI of 40 or above plus four or more qualifying conditions, with broader cohorts coming in stages over the next two years. GP practices began prescribing under the new contract from April 2026, but participation is optional. Some practices are involved; many are not yet. Waiting times vary significantly by area. For a detailed breakdown of how the NHS rollout applies to you, it is worth reading before assuming you qualify.

Private treatment through a regulated online pharmacy removes the waiting list. A prescriber still assesses you fully, but the eligibility criteria reflect the licensed indications in the medicine's summary of product characteristics: adults with a BMI of at least 30, or 27 and above alongside a weight-related health condition such as high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea. If you are ready to move forward, you can start the Mounjaro process with us now and a prescriber will review your answers the same day. BMI alone is not a rubber stamp, the prescriber weighs everything.

Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. Your prescriber will factor this in during the assessment.

How to get a Mounjaro prescription through a private pharmacy

Once you decide on the private route, the process at a regulated service is straightforward. At nume, it runs like this.

You complete a clinical questionnaire online. A GPhC-registered Independent Prescriber reads your answers the same day, not software, a named clinician. If your answers flag anything that needs clarification, they follow up. You then verify your identity with a photo ID and confirm your weight on a short video call. That step matters: it protects you and it is why we can be confident we are prescribing for the right person.

If the prescriber is satisfied you are clinically suitable, they issue a Mounjaro prescription and our GPhC-registered pharmacy dispenses it. Order before 12pm on a working day and it leaves the same afternoon. A DPD tracking notification arrives on your phone; the box itself is plain and unbranded. Inside, the KwikPen is sealed and cold-chain compliant, sourced through the licensed UK supply chain. For more on how dispensing works, see our pharmacy page.

Every repeat order goes through the same clinical re-review. There are no subscriptions and no automatic renewals.

Verifying any online pharmacy before you order

Mounjaro's rise in popularity has brought a parallel rise in unregulated sellers. The MHRA has publicly warned about counterfeit weight-loss pens circulating online and through social media, in late 2025 its enforcement team raided the first UK site found to be manufacturing fake tirzepatide pens. Fake pens have been found to contain insulin and other substances entirely different from the labelled content. The consequences can be serious.

The safe check is simple. Every legitimate UK online pharmacy must be registered with the General Pharmaceutical Council. You can look up any pharmacy by name or registration number at the GPhC register, nume's registration number is 9012878. If a seller is not on that register, do not order from them.

Red flags worth knowing: offers of these medicines without a clinical consultation, prices that seem dramatically below the rest of the market, discount codes from unfamiliar accounts on social platforms, and no visible GPhC or MHRA registration. Report anything suspicious at the MHRA's Yellow Card site, which handles both side-effect reports and suspect-seller concerns.

What the eligibility assessment actually covers

People sometimes assume that meeting a BMI threshold is sufficient and the prescription follows automatically. It is not quite that simple, and knowing what a prescriber considers helps you approach the consultation honestly.

Beyond BMI, your prescriber will look at current medications (some interact with tirzepatide), relevant medical history (including any personal or family history of thyroid conditions), and whether you have any conditions that would make treatment unsuitable. Pregnancy, breastfeeding and actively trying to conceive are contraindications. The medicine is not licensed for under-18s.

Women using oral contraceptives who start tirzepatide should use an additional non-oral method of contraception for the first four weeks of treatment and for four weeks after each dose increase, because the absorption of the pill may be affected, as noted in NHS England's guidance on weight management injections. Your prescriber will cover this with you.

The assessment is also the right moment to discuss any previous weight-loss treatment. Transfer patients can continue their current dose with appropriate evidence rather than restarting from scratch. If you have been on tirzepatide before or are transferring from another service, that is worth mentioning in your consultation, and our guide on how to buy a tirzepatide injection through a regulated UK service explains what to expect at each stage.
