Can I ask my GP for Mounjaro on the NHS?

Will my GP be able to prescribe Mounjaro?

It depends on two things: whether your practice has signed up to prescribe tirzepatide under the 2026/27 GP contract, and whether you meet the NHS criteria. Not every practice has opted in (NHS England describes participation as optional) so the honest answer is that your GP may want to help and still be unable to prescribe it through the NHS system at your surgery.

If your practice does participate, the current NHS eligibility framework is phased. The first cohort, active from June 2025, covers adults with a BMI of 40 or above who also have four or more of five specified conditions: high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease, or type 2 diabetes. A second cohort, covering BMI 35–39.9 with four or more of those same conditions, opened in June 2026. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. NHS England's weight-management injections guidance sets out these criteria in full.

It is also worth knowing that every NHS patient prescribed tirzepatide must take part in wrap-around diet and activity support as a condition of treatment. Meeting the BMI and conditions thresholds does not automatically guarantee access, the clinical picture always matters, and waiting times vary by area.

What if I meet the criteria but my GP says they're not prescribing it?

This is a common situation right now. Even where a GP is sympathetic, many practices are still working through the administrative side of the new contract, or have chosen not to participate at all in this first phase. You can ask your surgery directly, but if the answer is no, that does not mean treatment is out of reach.

A private prescription is one straightforward route. Licensed online pharmacies registered with the GPhC offer clinical consultations without a referral or a wait. The NICE appraisal of tirzepatide (TA1026) confirmed it is effective and appropriate for weight management, and the private-prescription eligibility mirrors the licensed criteria in the Mounjaro SmPC: adults with a BMI of 30 or above, or 27 or above with at least one weight-related condition such as high cholesterol, hypertension, or prediabetes.

If you want to understand more about the full range of weight-loss treatment options before deciding, that can help you frame the conversation with your GP more confidently too.

How do I actually have the conversation with my GP?

Asking your GP about Mounjaro directly is entirely reasonable. The medicine is NICE-recommended, and GPs are accustomed to patients raising it. A few practical points help the conversation go well.

Go in with your most recent weight and height, your GP will want to confirm your BMI. If you have any of the qualifying conditions listed above, mention them clearly. It is also sensible to ask whether your practice participates in the new prescribing scheme: some GPs may not yet know the answer, especially in smaller surgeries, and the question itself can prompt useful follow-up.

If your GP confirms the NHS route is not currently available at your practice, ask whether a referral to a specialist weight management service might be possible; Wegovy (semaglutide injection) can be accessed through those services under NICE TA875. Our guide to asking a doctor for Mounjaro covers these conversations in more detail. For context on what Mounjaro costs privately, that page lays out what a legitimate private prescription typically includes.

One thing patients tell us they wish they had known: Mounjaro arrives as a pre-filled KwikPen, stored in the fridge. Many people keep it in the fridge door next to everyday items, which is a helpful routine cue for a weekly injection. The pen is used once a week, and the prescriber (not the patient) manages any dose changes over time.

Are there any recent changes to the rules I should know about?

Yes, and they move quickly. The rules for Mounjaro on the NHS have shifted meaningfully in the past year. NICE published its recommendation in December 2024, the GP prescribing contract update came into force in April 2026, and the second NHS cohort opened in June 2026. Further cohorts are planned, each broadening the eligible population, though exact dates are subject to NHS England commissioning decisions.

On the private side, there are no waiting lists and no cohort restrictions, eligibility is decided against the licensed criteria by a prescriber at consultation. Both online and in-person private clinics are available. If you are weighing up the two routes, our Mounjaro overview page covers the licensed indications, how the medicine works, and what the clinical trials found. For anyone curious about where weight-loss medicine is heading, a comparison with retatrutide looks at what the next generation of treatments may offer. And if eligibility by age is something you have questions about, our page on the minimum age for Mounjaro answers that directly.
