âI am on warfarin (Coumadin Â®). Can I donate blood?â No. A person on a blood thinner (anticoagulant), like warfarin, will not be accepted as a blood donor because of the risk of bleeding to him/her when the vein in the arm is entered with a big needle or venous catheter during the donation process.
Avoid donating blood if you have a cold, a cold sore, a cough, a virus, or an upset stomach. Certain prescribed medications, such as antibiotics, can make you ineligible to donate blood. You must weigh at least 110 pounds or 50 kg. You have to be old enough. In many jurisdictions, parental permission is required for the ages 16â17 to give blood. Check the blood organization in your area if you are around this age. You can only donate blood every 56 days. If you have donated blood more recently than that, then you are not eligible again.
