Can I donate after receiving a tattoo?

Yes, if the tattoo facility is licensed.

If it is not licensed, you need to wait 12 months after getting a tattoo to give.

Can I donate after taking aspirin or over-the-counter anti-inflammatory medication?

You can donate if you are now feeling well and it has been at least 48 hours since you took the aspirin or aspirin-containing product.

Aspirin, acetaminophen and ibuprofen will not affect a whole blood donation. Apheresis platelet donors, however, must not take aspirin or aspirin-containing products 36 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.

Can I donate if I am pregnant?

If you are pregnant, you’ll need to wait until six weeks after you deliver before donating.

Can I donate if I am sick or taking prescription medications?

If you are taking an antibiotic or running a fever, you’ll need to wait for another time before donating.

Most prescription medications taken on a daily basis will not keep you from donating.  However, there are some medications that could cause you to be deferred.

  • You develop symptoms suggestive of Zika virus infection within 2 weeks following donation
Should I wait for a local emergency or natural disaster to donate?

Patients in the hospitals we serve need blood everyday. Your donation is, literally, a matter of life and death to someone in need of it. Typically, there is a two-day period from the time of donation until that blood is available to a patient, so we must have blood available before an emergency or natural disaster occurs.
