I was deferred because of a medication. When can I donate again?
What this deferral usually means
The waiting period is usually about the medication or the condition it treats, not a judgment about you. Never stop a prescribed medication just to donate.
What to ask the center
Ask which medication caused the deferral and exactly how long you need to wait after your last dose.
When you can try again
Depends entirely on the medication. Some need a few days, some a month, and some only while you are taking them.
Set a return reminderPrepare for your comeback
- Write down the exact medication name and your last dose date
- Talk to your prescriber before changing anything
- Confirm the waiting period with the center
