Can you donate blood while taking antibiotics?
Generally not while you have an active infection or are mid-course. After you finish the antibiotics and feel well, you can usually donate. Some centers set a short waiting time, so check with yours.
Antibiotics themselves are not the main issue. The problem is the infection you are treating, and whether you have recovered.
Antibiotics
- Active infection: you should wait until you have completed treatment and feel well
- Finished the course and healthy: many centers accept you right away, while some ask for a few days
- Antibiotics for acne or prevention: often accepted if the condition is under control
- Topical antibiotics such as ointments for a small wound are usually fine
Ivermectin
Ivermectin treats parasitic infections such as scabies and certain worm infections. Eligibility depends on the infection you had and whether it has been treated and resolved.
Examples
| Situation | What to expect |
|---|---|
| Taking amoxicillin for a throat infection | Wait until finished and well |
| Course finished, feeling fine | Generally eligible, some centers wait a few days |
| Daily antibiotic for acne | Often eligible |
Important
Finish your antibiotic course exactly as prescribed. Never stop early just to donate sooner.
