August 22, 2025 – Clinical Trialsdiabetes

The NHS Business Services Authority’s annual ‘Prescribing for Diabetes – England 2015/16 to 2024/25’ report reveals that diabetes treatments now account for 15% of all NHS prescription spending, up from 10% in 2015/16 when costs were £960 million.

Anti-diabetic drugs costs have risen by 18% in the last year. A significant factor in this year’s cost increase is Tirzepatide, branded as Mounjaro, which has emerged as a new driver of spending growth alongside established treatments like Dapagliflozin (Forxiga). From 2023/24 to 2024/25, the cost of Tirzepatide increased 340-fold to £120 million and Dapagliflozin costs increased 42% to £333 million.

Anti-diabetic drugs were the most prescribed treatment for diabetes, making up 59% of prescribed items and 75% of the total cost of diabetes treatments at a cost of £1.1 billion.

The rising costs coincide with record patient numbers, as 3.9 million people now receive diabetes treatment in England – a 7% increase from 3.6 million in 2023/24. Prescription items reached 77 million in 2024/25, up 9% from the previous year and 56% higher than the 50 million items prescribed in 2015/16.

Key findings also show that:

  • the overall cost of prescribed items for treating diabetes has increased by 15% from £1.67 billion to £1.92 billion.
  • health inequalities persist. Areas with higher deprivation levels had 349,000 more diabetes patients than the least deprived areas.
  • men aged 60 to 64 represent the largest patient group, with 284,000 people accounting for 7% of all identified cases.
  • patient numbers have grown by an average of 6% annually over the past three years.
  • Tirzepatide, branded as Mounjaro, was prescribed to 188,065 identified patients in 2024/25 compared to 2,242 in 2023/24.
