Hypertension or low blood pressure

Hypertension and medication for it are not obstacles to blood donation if the blood pressure can be managed with the drug therapy. To ensure that the body has become used to the effects of the medication, drug therapy must have been started at least two weeks before donating blood.

If you have low blood pressure, you may donate blood if you are asymptomatic without medication. If your low blood pressure causes symptoms of illness, you take a medicine that raises blood pressure, or if you have fainted because of your low blood pressure, we do not recommend that you donate blood. Young people often have lower blood pressure, which, for most people, corrects itself with age.
