Rifaximin prescribing across the NHS.
Rifaximin is 136,000 items and £24m a year of highly concentrated prescribing: hepatic encephalopathy prevention at £179 an item, written by fewer than half of England's practices and driven almost entirely by hepatology shared care. Small line, serious money, no generic pressure.
The NHS in England dispensed 136,331 prescription items of Rifaximin in the 12 months to May 2026, across primary care and hospitals.
Spending on Rifaximin over those 12 months was £24.4m at net ingredient cost, the list price of what was dispensed before any discounts.
Items were up 8.2% on the previous 12 months.
72% of Rifaximin volume moved through primary care and 28% through hospital pharmacies.
Rifaximin ranks #2 of 11 chemical substances in Some other antibacterials (BNF 5.1.7), by items dispensed.
Among Integrated Care Boards, NHS North East and North Cumbria ICB dispensed the highest volume of Rifaximin.

Split of items across NHSBSA primary care and SCMD hospital dispensing.
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.

Each nation publishes its own community prescribing data, with different coding and list rules, so read these per-nation rather than as an exact UK total. Sources: NHSBSA (England), Public Health Scotland.
What open data won't tell you about rifaximin.
Liver disease follows deprivation, and shared-care availability follows geography; both shape this line invisibly.
Asked and answered.
Is rifaximin prescribing rising or falling in the NHS?
Rising. England dispensed 136,331 items of Rifaximin in the 12 months to May 2026, up 8.2% 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 rifaximin?
£24.4m at net ingredient cost in the 12 months to May 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 rifaximin prescribed most?
By raw volume, NHS North East and North Cumbria ICB dispensed the most rifaximin 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 May 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.
