In almost all cases, medications will not disqualify you as a blood donor.

Many medications do not impact eligibility, including those for high blood pressure and allergies, birth control pills, vitamins and diet pills.  Over-the-counter oral homeopathic medications, herbal remedies and nutritional supplements are acceptable.

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.

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.  Located here is a list of common medications and their deferral lengths.

For clarification, further information or specific questions about medications you have taken in the past or are currently taking, please call 1-8oo-310-9556, Option 1 (or direct dial 412-209-7035) to contact our Medical Help Desk.  You can also submit an inquiry through our Contact Us page.
