Colesevelam prescribing across the NHS.
Colesevelam's licence says cholesterol; a large share of its real use is bile acid diarrhoea, off-label, where few alternatives exist. 257,000 items at £121 an item makes it one of the most expensive routine tablets in primary care, and the line keeps growing.
The NHS in England dispensed 259,142 prescription items of Colesevelam in the 12 months to May 2026, across primary care and hospitals.
Spending on Colesevelam over those 12 months was £31.4m at net ingredient cost, the list price of what was dispensed before any discounts.
Items were up 14.3% on the previous 12 months.
93% of Colesevelam volume moved through primary care and 7% through hospital pharmacies.
Colesevelam ranks #9 of 23 chemical substances in Lipid-regulating drugs (BNF 2.12), by items dispensed.
Among Integrated Care Boards, NHS North East and North Cumbria ICB dispensed the highest volume of Colesevelam.

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.

Is colesevelam prescribing rising or falling in the NHS?
Rising. England dispensed 259,142 items of Colesevelam in the 12 months to May 2026, up 14.3% 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 colesevelam?
£31.4m 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.
