Type 2 diabetes: Medication Cost, US vs UK
Type 2 diabetes is treated across several drug classes — from low-cost metformin to higher-cost GLP-1 agonists and SGLT2 inhibitors — so the per-dose cost gap between older and newer therapies is wide.
How much do type 2 diabetes medications cost in the US vs the UK?
Type 2 diabetes is treated across several drug classes — from low-cost metformin to higher-cost GLP-1 agonists and SGLT2 inhibitors — so the per-dose cost gap between older and newer therapies is wide. On average US Medicare Part D spend per dose (calendar year 2024, CMS), the options range from $0.0564 (Metformin HCl) to $511.63 (Mounjaro); the most-prescribed is Metformin HCl at $0.0564. In England, an NHS patient pays a flat £9.90 per item for any of them (2026/27 (from 1 April 2026)). The two figures are different measures and are not converted.

Not medical advice. The figures on this page are drawn unchanged from public government datasets for general information only. They are not price quotes and not a substitute for professional advice. What you actually pay depends on your country, pharmacy, insurance, manufacturer, dose and region. Never start, stop or switch a medication on cost grounds without a licensed pharmacist or clinician.
The US figure is Medicare Part D PROGRAM spending per dosage unit (in US dollars), not a cash price; the UK figure is the patient's flat NHS charge per item (in pounds). They measure different things in different currencies and are shown side by side, never converted into one another.

Frequently asked questions
- What is the cheapest medication for type 2 diabetes?
- By average US Medicare Part D spend per dose (calendar year 2024), the lowest-cost option among the type 2 diabetes medications listed here is Metformin HCl at $0.0564. That is a cost figure only — the right medicine for you is a clinical decision.
- What does treating type 2 diabetes cost on the NHS in England?
- In England, an NHS patient pays a flat £9.90 per dispensed prescription item (2026/27 (from 1 April 2026), frozen) — the same charge for any drug, whatever it costs the NHS — or nothing at all with a Prescription Prepayment Certificate (£114.50/year cap, worth it above 11 items/year) or an exemption. NHS prescriptions are free outright in Scotland, Wales and Northern Ireland.
- Why such a wide US cost range for type 2 diabetes?
- Because the medicines used span older low-cost generics and newer branded drugs. The cheapest (Metformin HCl, $0.0564/dose) and priciest (Mounjaro, $511.63/dose) here differ on the US per-dose measure — yet in England the patient pays the same £9.90 for either.
