Can I donate blood if I am taking antibiotics?
What this means
- Antibiotics for an active infection: wait until the course is done and the infection has cleared.
- Low-dose or topical antibiotics for acne: usually not a problem.
- Preventive antibiotics, such as before dental work, do not usually cause a deferral on their own.
What to do next
Finish your course, recover, then book a donation.
When to call the center: Call if you are unsure whether your prescription counts as treating an active infection.
If you need to wait
Wait until the antibiotic course is finished and the infection has resolved.
Exact timing is confirmed by the center. Set a reminder so you do not have to track it.
Set a return reminderWhy this rule exists
The deferral is about the infection being treated, not the antibiotic itself.
This is general educational guidance, not a final eligibility decision. Donation centers make final eligibility decisions during confidential screening. Rules may vary by center, donation type, location, and current policy.
