Weight-Loss Jabs Now Available from GPs – But Only for Those Who Meet Strict NHS Rules

A major change is underway in England’s battle against obesity. From late June 2025, NHS GP surgeries across England can now prescribe powerful weekly weight-loss injections like Mounjaro (tirzepatide) to patients who meet strict criteria. Previously, these medications were only available in specialist clinics. This phased rollout aims to help those at highest health risk while managing GP workload and NHS resources.



What Are Mounjaro and Wegovy?

Mounjaro and its cousin Wegovy (semaglutide) are once-weekly injectable medications that mimic gut hormones responsible for signalling fullness to the brain. This effect helps patients feel satisfied on smaller portions, often resulting in significant weight loss. Clinical trials published in The Lancet Diabetes & Endocrinology demonstrate that tirzepatide can reduce body weight by 15 to 20 per cent on average (2022).

Initially approved for type 2 diabetes, these drugs have now gained recognition as effective treatments for obesity due to their strong appetite-suppressing effects. Dr Claire Fuller, NHS England’s co-medical director for primary care, highlights that these medicines are an important part of a wider weight-management plan that includes healthy eating and regular exercise (NHS England News, 2025).

Who Can Get These Injections from Their GP?

The NHS has set clear and strict eligibility rules. To qualify for a GP prescription, patients must have severe obesity combined with significant related health conditions. The first group includes individuals with a body mass index (BMI) of 40 or higher (or 37.5 and above for some non-White ethnic groups) who also have at least four of the following five health issues:

  • Type 2 diabetes

  • High blood pressure

  • Heart or vascular disease (such as heart attack or stroke)

  • High cholesterol

  • Obstructive sleep apnoea (pauses in breathing during sleep)

NHS England guidance means that only a small number of people will initially be eligible to receive Mounjaro or Wegovy via their GP (NHS.uk, 2025). Those who do qualify will also benefit from comprehensive support, including regular medical reviews and expert advice on diet and exercise, ensuring the best possible outcomes.

Why Might There Be Delays?

Even if you meet eligibility, the injections won’t be available immediately at every GP surgery. Many clinics are still setting up systems and training staff to manage these treatments safely. The chair of the Royal College of General Practitioners, Professor Kamila Hawthorne, warns that while these medicines are effective, GP teams are already under intense pressure, so demand may exceed capacity at first (BBC Health, 2025).

Patients starting Mounjaro require close monthly monitoring and lifestyle support, which adds to the workload for GP practices. To manage this, some GPs are arranging group information sessions or referring patients to specialist community services.

Pharmacists have also cautioned that supplies may be limited initially. For those unable to access these injections promptly through the NHS, private prescriptions remain an alternative, though at a higher cost. Websites like Mango Compare provide useful tools to compare private prices for Mounjaro and Wegovy.

Who Cannot Take These Injections?

Certain groups are excluded due to safety concerns, including:

  • Pregnant or breastfeeding women, or those trying to conceive

  • People with a history of pancreatitis or specific thyroid cancers such as medullary thyroid carcinoma or multiple endocrine neoplasia type 2 (MEN2)

  • Anyone with a history of severe allergic reaction to these drugs

A thorough medical assessment by a GP or specialist is essential before starting treatment, with a clear discussion of potential side effects such as nausea or stomach discomfort (NICE Guideline NG209, 2024).

What If You Don’t Qualify Yet?

If you don’t meet the current criteria, there’s no need to lose hope. NHS England plans to broaden eligibility over the coming years, with the following schedule:

  • June 2026: People with BMI between 35 and 39.9 (or 32.5–37.4 for some ethnic groups) plus four related health conditions

  • April 2027: People with BMI 40 or above (37.5+ for specified groups) with three of the five listed conditions

After these stages, NICE will review the programme to determine if it can be expanded further. Analysts estimate around 3.4 million people in England could eventually be eligible for weight-loss injections through the NHS in the next decade (Health Policy Insight, 2025).

What About Wales, Northern Ireland, and Scotland?

Access to these injections varies across the UK:

  • Wales: Mounjaro is available via specialist NHS clinics, with potential plans to involve GPs in the future.

  • Northern Ireland: A phased rollout of a regional obesity service is underway, which will provide community access to these treatments.

  • Scotland: Weight-loss injections are rarely prescribed on the NHS, as decisions on funding are made by local health boards. Consequently, only a small number of patients have received Mounjaro so far (The Scotsman, 2025).

No matter where you live, it’s best to consult official NHS or health board websites regularly for the latest guidance.

Final Thoughts

Weight-loss injections like Mounjaro and Wegovy represent an important advancement in managing severe obesity and related health risks. However, they come with strict eligibility rules and require ongoing medical supervision combined with lifestyle changes. If you believe you qualify, speak to your GP but prepare for possible waiting times while services expand.

For those who want quicker access or do not currently meet NHS criteria, private options are available. Use trusted price comparison sites such as Mango Compare to find safe and competitive prices.

Above all, ensure you discuss any treatment decisions thoroughly with a healthcare professional to find the best and safest approach for your weight-loss journey.
