Propecia and Organ Donation

Does being on propecia inhibit someone from donating an organ, or for that matter, blood to another person? Will being on propecia affect matching tests?

If it does, what is the time period that i need to stop the medication before i can donate or go through tests to see if I am a match?

Taking Propecia will not affect the tests for matching blood or organs. I’m not aware of any problem with donating organs while taking Propecia, but I’m sure the doctors will pre-screen you.

Donating blood is a different story, however, as your blood can wind up in a woman who then becomes pregnant, then leading to complications with the baby (for example). The time period is 1 month off Propecia (finasteride) before donating blood, 6 months for Avodart (dutasteride). There are a handful of drugs that make you ineligible for blood donation, and you can find the list at the Red Cross site.
