Minoxidil and Blood Donation

Hi Doctor,

I have been donating blood regularly. But I have hair loss and would like to try applying topical minoxidil on my scalp. Would my blood be safe to donate? Look forward to your kind response.

Best regards

Always reveal the medications you take when you donate blood. I doubt that a topical like minoxidil will be a problem for blood donation, as little of it gets absorbed, if any. I would suggest that you stop taking minoxidil for two days prior to the donation so that any of the drug that might be absorbed by your body will be gone before the donation.
