Following revision of the national directive, these donors could be allowed, providing stable dose for at least 3 months, adequate blood pressure control and no adverse effects caused by the therapy. The new practice was evaluated by a quality study where the major aim was to establish whether donations from blood donors on antihypertensive medication pose a risk to the donor. The risk was assessed by counting the number and categorizing the adverse events related to blood donation. In addition, the quantitative effect of including these donors was calculated.Subjects and Methods: In this retrospective quality study, blood donors on antihypertensive therapy were recruited from four different blood centers to fill out a questionnaire. A total of 265 donors answered questions regarding their health status, type of medication used, and adverse events connected to blood donation both before and after starting the therapy.Results: No severe adverse events were observed in donors on antihypertensive medications. The amount of mild adverse events, as exhibited by only 7 persons (0.46%) in this donor population, was the same as for donors without hypertensive treatment.Conclusion: Blood donation from persons on antihypertensive therapy poses no extra risk of severe adverse events, given the use of screening criteria to identify and bleed only low-risk donors.Keywords: donor safety, hemovigilance, hypertension, deferral
