What countries is Mounjaro available in — and what that means for UK patients

The countries where Mounjaro is currently approved

Tirzepatide reached patients first in the United States, where the FDA approved it in May 2022 for type 2 diabetes under the Mounjaro brand. The weight-management indication followed there in late 2023, under a separate brand name, Zepbound. It is worth being clear about that distinction: Zepbound does not exist as a UK product. Outside the US, tirzepatide is sold as Mounjaro regardless of whether it is being prescribed for diabetes or weight management.

The European Medicines Agency granted approval for tirzepatide across EU member states in 2023, with individual countries rolling out supply at different speeds thereafter. Canada, Australia, and Japan have each granted their own regulatory approvals, and Eli Lilly has been expanding market access progressively. The UK's own regulator, the MHRA, authorised Mounjaro independently, a reminder that post-Brexit UK licensing follows its own process and timeline, not the EU's.

If you want to understand the specific UK position in more depth, our page on whether Mounjaro is available in the UK covers the licensing history, NHS rollout phases, and private access routes in full.

Why availability in other countries doesn't help UK patients much

A common misconception is that if a medicine is freely available abroad (say, from a US online pharmacy) a UK resident could simply order it internationally. That is not how it works, and it carries real risks.

Medicines licensed in one country are not automatically legal to import for personal use in another. Beyond the legal complexity, the supply chain matters enormously. The MHRA has seized approximately 20 million doses of illegally traded weight-loss medicines (around £45 million street value) in enforcement operations through 2025, including the first UK site found manufacturing counterfeit tirzepatide pens. Fake pens have in some cases contained insulin, with serious consequences for the people who used them. International sellers, however convincing their websites appear, sit entirely outside the oversight that protects patients here.

The safe route in the UK is through a pharmacy you can verify on the GPhC register, and where every supply follows a clinical assessment by a registered prescriber. That applies whether you approach a GP surgery, a hospital clinic, or a regulated online pharmacy like nume.

The UK licence and who it covers

Within the UK, Mounjaro's weight-management licence covers adults with a BMI of 30 or above, or a BMI of 27 or above alongside at least one weight-related condition such as high blood pressure, high cholesterol, type 2 diabetes, obstructive sleep apnoea, or cardiovascular disease. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. The treatment is taken as a once-weekly subcutaneous injection, starting at 2.5 mg, with dose increases guided by the prescriber.

NICE recommended tirzepatide for NHS use in December 2024 (TA1026), though NHS access is being phased in gradually and criteria are stricter than the licensed indication. Private prescribing follows the licensed criteria rather than the NHS eligibility thresholds, which is why many people access treatment through a regulated private pharmacy while NHS availability expands. For context on how private pricing compares across providers, the cost of Mounjaro in the UK page sets out what a legitimate private prescription typically includes.

Treatment abroad is a separate question some readers raise: if you have started Mounjaro in the UK and are travelling, the pen can be carried with appropriate documentation, but any change in dose, missed-injection guidance, or supply question should go back to your UK prescriber. The Mounjaro treatment overview covers storage and travel practicalities alongside the clinical picture.

What to do if you are in the UK and want to explore treatment

If tirzepatide is available in your country of residence, the first step is always the same: a clinical assessment with a qualified prescriber. In the UK that means a GP, a specialist clinic, or a GPhC-registered online pharmacy. There is no other lawful route. Our tirzepatide information page gives a fuller grounding in how the medicine works before you decide whether a consultation is right for you.

One thing to be aware of: questions about oral or tablet forms of tirzepatide come up regularly. As of mid-2026, Mounjaro in the UK is an injection only, and if you are wondering whether oral tirzepatide is available, that page explains the current regulatory position and what may be on the horizon. If you have read about Mounjaro in tablet form, that covers what is and is not currently licensed. The broader weight-loss treatment options page sets out the full range of licensed alternatives available through nume, including the recently approved oral semaglutide (Wegovy tablets), if injections are not your preference.
