Frequently Asked Questions
I just finished a Z-pack yesterday - when can I donate?
Typically, you can donate 24-72 hours after your last dose, as long as you're symptom-free and feeling well. Call your center to confirm their specific policy.
I take doxycycline for acne - can I donate?
Often yes. When antibiotics are taken long-term for non-infection reasons (like acne), many centers allow donation. The key is you're not actively fighting an infection. Confirm with your center.
Why does the reason matter?
The antibiotic itself isn't usually the problem - the infection is. If you have an active bacterial infection, you shouldn't donate. Once the infection is cleared and you've finished treatment, you can resume.
I feel fine - can I donate before finishing my antibiotics?
No. Complete your full antibiotic course first. Stopping early can allow the infection to return and contribute to antibiotic resistance. Your health comes first.
Always complete your full antibiotic course, even if you feel better. After you've finished and waited 24-72 hours symptom-free, you can typically return to donating.
