What medications prevent people from donating blood?

American Red Cross
Administration
In almost all cases, medications will not disqualify you as a blood donor. Your eligibility will be based on the reason that the medication was prescribed. As long as the condition is under control and you are healthy, blood donation is usually permitted. Over-the-counter oral homeopathic medications, herbal remedies, and nutritional supplements are usually acceptable. There are a handful of drugs that are of special significance in blood donation. Persons on these drugs have waiting periods following their last dose before they can donate blood:
- Accutane, Amnesteem, Claravis or Sotret (isoretinoin), Proscar (finasteride), and Propecia (finasteride) - wait 1 month from the last dose.
- Avodart (dutasteride) - wait 6 months from the last dose.
- Aspirin, no waiting period for donating whole blood. However, you must wait 48 hours after taking aspirin or any medication containing aspirin before donating platelets by apheresis.
- Feldene (piroxicam), no waiting period for donating whole blood. However, you must wait 48 hours after taking Feldene (piroxicam) before donating platelets by apheresis.
- Clopidogrel - wait 14 days after taking this medication before donating platelets by apheresis.
- Coumadin (warfarin), heparin or other prescription blood thinners – you should not donate since your blood will not clot normally. If your doctor discontinues your treatment with blood thinners, wait 7 days before returning to donate.
- Hepatitis B Immune Globulin - given for exposure to hepatitis, wait 12 months after exposure to hepatitis.
- Human pituitary-derived growth hormone at any time - you are not eligible to donate blood.

Blood Basics

Our blood is a living tissue with a variety of critical functions: It delivers oxygen and nutrients to our organs, fights infections and creates blood clots, preventing us from bleeding excessively when a blood vessel is damaged. ...

The liquid part of our blood, called plasma, is key for maintaining blood pressure and supplying critical proteins for blood clotting, immunity and maintaining the correct pH balance in our body -- critical to cell function. Plasma also carries the solid part of our blood -- white blood cells, which work to destroy viruses and bacteria; red blood cells, which carry oxygen through the body; and platelets, which help clotting.
