Aspirin, acetaminophen and ibuprofen will not affect a whole blood, plasma or double red cell donation. Apheresis platelet donors, however, must not take aspirin or aspirin-containing products for 48 hours prior to donation. Aspirin reduces the potency and performance of your platelets. The more time between taking aspirin and donating blood, the better for the recipient.
It is recommended that you call the donor center before you come to donate to inquire about any medications you are taking. Most times, taking medications will not keep you from donating.

Malaria Risk
- The CDC keep track of the locations with malaria risk for travelers from the U.S. Because the list of malaria-endemic areas is frequently updated, you are encouraged to visit the CDC website.
- Bring a list of your exact areas of travel with you when you come to donate blood. Often it’s not the entire country that is at risk for malaria, just certain areas of it. Knowing exactly where you have traveled is essential. The CDC website offers a list that keeps track of each country’s malaria risk.
- Know the date you returned to the United States. If you traveled to a malaria-endemic area and stayed for less than six months, there is a three-month deferral period for blood donation. The three months begin the day you return to the United States.
- If you’ve been been a resident of a high malaria risk country, however, you still remain deferred for 3 years.
Creutzfeldt-Jacob Disease (“Mad Cow Disease”) Risk
- Those who spent extended time in many European countries are now no longer deferred due to Mad Cow Disease risks. This change will likely allow many veterans and military personnel to donate blood.
- Individuals in the following groups will remain deferred because of European residency:
- Those who spent three months or more in the United Kingdom from 1980-1996*
- Those who spent five years or more in France or Ireland from 1980-2001
- This is the FDA recommendation due to symptoms of Creutzfeldt-Jacob Disease that may not appear until much later. The U.K. comprises England, Northern Ireland, Scotland, Wales, the Isle of Man, the Channel Islands, Gibraltar and the Falkland Islands.
