Hydroxocobalamin prescribing across the NHS.
Hydroxocobalamin is the B12 injection: 3.3m items a year, each one implying a nursing appointment the drug cost never shows. The molecule costs pennies; the delivery model is the expensive part, which is exactly why the oral switch on the cyanocobalamin page is happening.
The NHS in England dispensed 3,361,195 prescription items of Hydroxocobalamin in the 12 months to July 2026, across primary care and hospitals.
Spending on Hydroxocobalamin over those 12 months was £8.7m at net ingredient cost, the list price of what was dispensed before any discounts.
Items were up 3.9% on the previous 12 months.
82% of Hydroxocobalamin volume moved through primary care and 18% through hospital pharmacies.
Hydroxocobalamin ranks #2 of 3 chemical substances in Drugs used in megaloblastic anaemias (BNF 9.1.2), by items dispensed.
Among Integrated Care Boards, NHS North East and North Cumbria ICB dispensed the highest volume of Hydroxocobalamin.

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.

Injection frequency varies by patient and protocol, so items map onto people worse than for most lines.
Asked and answered.
Is hydroxocobalamin prescribing rising or falling in the NHS?
Rising. England dispensed 3,361,195 items of Hydroxocobalamin in the 12 months to July 2026, up 3.9% 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 hydroxocobalamin?
£8.7m 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 hydroxocobalamin prescribed most?
By raw volume, NHS North East and North Cumbria ICB dispensed the most hydroxocobalamin 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.
