How the NHS provides Mounjaro
From March 2025, NICE has approved tirzepatide (Mounjaro®) for the treatment of obesity within the NHS in England.
Eligibility criteria
To be eligible for Munjaro on the NHS, patients must meet the following criteria:
Phase 1 (2025-2026): BMI ≥ 40 kg/m² (≥ 37.5 for certain ethnic groups) and at least four of the following weight-related conditions:
Type 2 diabetes
Hypertension
Cardiovascular disease
Obstructive sleep apnea
Future expansion (within three years): In line with NHS targets, patients with a BMI ≥ 35 and comorbidities may be eligible for this service, covering approximately 220,000 patients.
Application Steps
Check your BMI and comorbidities: Ask your GP to ensure this information is accurately recorded – your GP may measure your weight and height during a routine consultation.
Participate in a clinical assessment: A team of specialists will assess your health, discuss a lifestyle plan, and determine if Mounjaro is right for you.
Enter comprehensive care: If approved, you will receive only medication and structured support (nutrition, exercise, and behavioral guidance).
Stay informed: As local rollouts vary, please monitor your GP or comprehensive care board for updates on when prescriptions will be available in your area.
Conclusion:
Mounjaro is one of the most effective weight-management medicines approved for NHS use, but access is carefully phased and limited to those with severe obesity and multiple health conditions. The process begins with your GP and leads into specialist services, where treatment is combined with lifestyle support to ensure safety and long-term success.
