If prescribed antibiotics, you are eligible to donate 24 hours after your last dose. If taking antibiotics as a preventative measure, you are eligible to donate.
Other medications may require a temporary or permanent deferral. The list of medications that may prevent you from donating is constantly changing, so if you were deferred in the past, we encourage  you to confirm your eligibility from time to time, as you may once again become eligible.
