Supporting information

Additional information

The rationale for not accepting donors on medication, other than beta blockers or diuretics, for the treatment of hypertension was reviewed by the Standing Advisory Committee on the Care and Selection of Donors (SACCSD) in 2008. It was decided that available data did not support the deferral of all individuals with controlled hypertension taking other medications.

In the UK, about 1 in 20 individuals has hypertension. Most people with hypertension are in good health and are fit to donate blood.
It is important to ensure that donors on antihypertensive treatment are not experiencing hypotensive side effects from their medication.

Reason for change:
Removal of additional information about the cardiac and renal complications associated with hypertension that are contained within the relevant ‘Cardiovascular disease’ and ‘Impaired renal function’ entries. A link to the latter, which is a new entry, has been added. The link to the former ‘Kidney and bladder disease’ entry has been removed.
