Can You Give Blood With High Blood Pressure

It is acceptable to donate blood as long as your blood pressure is below 180 systolic (first number) and below 100 diastolic (second number) at the time of donation. Medications for high blood pressure do not disqualify you from donating blood. Therefore, you can donate if your blood pressure is controlled by medication. According to the American Red Cross the criteria for giving blood for transfusions to another person include being at least 17 years old or 16 years old if allowed by state law, weighing at least 110 pounds, and not having donated whole blood in the last eight weeks.

  • When you have high blood pressure, the pressure in your arteries is elevated.
  • About 50 million Americans -- one in four adults -- have high blood pressure. When untreated, it can increase the risk of heart attack and stroke.
