Warfarin prescribing across the NHS.
Warfarin is down to 2.8m items a year and still falling as the DOACs finish their takeover. It will not reach zero: mechanical heart valves, severe kidney disease and a few other corners still need it. What remains is the irreducible core, plus patients who simply never switched.
The NHS in England dispensed 2,765,235 prescription items of Warfarin in the 12 months to July 2026, across primary care and hospitals.
Spending on Warfarin over those 12 months was £6.2m at net ingredient cost, the list price of what was dispensed before any discounts.
Items were down 8.0% on the previous 12 months.
94% of Warfarin volume moved through primary care and 6% through hospital pharmacies.
Warfarin ranks #4 of 9 chemical substances in Oral anticoagulants (BNF 2.8.2), by items dispensed.
Among Integrated Care Boards, NHS Central East ICB dispensed the highest volume of Warfarin.

Prescribing by deprivation.
Items per 1,000 registered patients by deprivation decile (1 = most deprived), practice deprivation weighted by where each practice's patients live. Read the shape rather than the absolute level: the most and least deprived deciles cover far fewer practices, and age structure drives much of the gradient.

What open data won't tell you about warfarin.
The INR monitoring that makes warfarin genuinely expensive happens in clinics and labs, none of which appears in prescribing spend. The drug is cheap; the service around it is not.
Asked and answered.
Is warfarin prescribing rising or falling in the NHS?
Falling. England dispensed 2,765,235 items of Warfarin in the 12 months to July 2026, down 8.0% on the previous 12 months. Items count prescriptions dispensed, not patients treated, so the change can reflect dose and duration shifts as well as patient numbers.
How much does the NHS spend on warfarin?
£6.2m at net ingredient cost in the 12 months to July 2026. Net ingredient cost is the list price of the medicine before discounts and rebates; the NHS's final bill, especially for hospital medicines, is usually lower.
Where in England is warfarin prescribed most?
By raw volume, NHS Central East ICB dispensed the most warfarin in the last 12 months. Raw volume favours the biggest populations; the map on this page shades every ICB by items per head to correct for that.
How up to date is this data?
This page runs to July 2026, the most recent NHSBSA release. Prescribing data publishes roughly six to eight weeks in arrears, and DoseTrend refreshes within 48 hours of each monthly release.
