How to Get Mounjaro: The Legal UK Route, Step by Step

Step 1, confirm you're on the right route

Mounjaro (tirzepatide) is licensed in the UK for weight management in adults with a BMI of 30 or above, or 27 or above alongside at least one weight-related condition such as high blood pressure, high cholesterol, type 2 diabetes, or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. That eligibility outline gives you a starting point, but a prescriber assesses the full picture (medical history, current medications, and anything that might affect suitability) before any prescription is written.

There are two broad routes: NHS and private. NHS access to Mounjaro is currently phased, tightly criteria-based, and subject to waiting times at your local practice or specialist service. Private prescription through a regulated online pharmacy is the alternative for people who don't meet the current NHS thresholds or don't want to wait, and our page on how to get Mounjaro online walks you through exactly what that process involves. The Mounjaro treatment page covers both routes in detail.

Step 2, choose a pharmacy you can verify

If you go the private route, the single most important check is whether the pharmacy holds a valid GPhC registration. The General Pharmaceutical Council's public register lets you search any online pharmacy by name or registration number in seconds. Legitimate pharmacies display their GPhC number clearly; if you can't find one, or if a seller is offering Mounjaro without requiring a clinical assessment, treat that as a serious red flag.

The MHRA has warned publicly about fake weight-loss pens circulating online and via social media, counterfeit pens have been found to contain insulin rather than tirzepatide, with real harm resulting. In 2025, enforcement operations seized around 20 million doses of illegally traded weight-loss medicines (roughly £45 million street value), and the first UK site manufacturing fake tirzepatide pens was raided. The MHRA's Yellow Card scheme lets you report suspect sellers directly. For details on what to look for when buying online, our guide to buying Mounjaro online safely goes through each check.

Step 3 (complete a clinical consultation and get your prescription

At nume, getting Mounjaro starts with a free online consultation) a structured clinical questionnaire that covers your weight, health history, current medicines and goals. You don't need a GP referral or a previous diagnosis. Once you submit, a GPhC-registered Independent Prescriber reviews everything personally. If you're clinically suitable, the prescription is issued the same day.

Identity and weight are verified (photo ID and a live video weight check) before your first order is processed. That's not box-ticking; it's how a clinical decision gets made properly. Transfer patients and anyone requesting a dose increase provide supporting evidence as part of the same review. Our clinical team page explains who reviews your consultation. If you have questions before you start, our FAQs cover the most common ones, or you can reach the team directly via our contact page.

Step 4 (receive your treatment and know how to use it safely

Once approved and dispatched, your Mounjaro pen arrives the next working day in plain packaging via DPD) fully tracked so you know exactly when to be in. The pen lives in the fridge door until you're ready to use it; each KwikPen contains four weekly doses. Your Patient Information Leaflet covers storage, injection technique and what to do if you have concerns, always the first place to check for practical detail, alongside your prescriber.

Mounjaro is a once-weekly subcutaneous injection. Treatment starts at 2.5mg (the starter dose is there to let your system adjust, not to deliver maximum effect) and is titrated by your prescriber from there. Every repeat order at nume is clinically re-reviewed before it ships; there are no automatic renewals. If at any point you want to understand what stopping the medicine involves, this page covers what to expect. For a practical overview of the injection itself, see our guide to getting the Mounjaro jab. The NHS tirzepatide medicines page is a good independent reference for side effects and safety information.
