Can you donate blood with a yeast infection?
It depends on the timing. If you have symptoms or are mid-treatment, wait. After you have finished treatment and feel well, you can generally donate.
A yeast infection (candidiasis) is a fungal infection, most often caused by Candida albicans. It is very common and can affect the vaginal area, mouth (thrush) or skin.
Active infection
During an active infection, the body is fighting something off. Blood centers generally ask you to feel healthy on the day, so an active infection means waiting. That applies to vaginal, oral or skin yeast infections that are still causing symptoms.
How long after treatment
There is no single fixed rule. It is a clinical decision: you should be free of symptoms and have completed the treatment. In practice, many centers are fine once you feel well again.
Recurrent infections
Frequent infections can point to an underlying issue (poorly controlled diabetes, a weak immune system, steroids). In those cases the screener looks at the underlying condition.
Antifungal medications
| Situation | Donation |
|---|---|
| Taking oral fluconazole | Wait until finished and symptom free |
| Using a cream or suppository | Mention at screening, evaluated individually |
| Treatment completed, no symptoms | Generally eligible |
A resolved yeast infection does not stop you from donating.
This information is general and does not replace advice from a health professional. Your eligibility is always decided at the donor screening on the day of donation. Rules change, so confirm with the American Red Cross or the blood center where you plan to donate.
