Can I give blood while on propecia?


QUESTION:  Hi Dr Jones.  I went to give blood today and being on propecia realized that I was unable to.  I have always given blood quite regularly so it came as a bit of a shock.  Is it true that as long as I am on propecia I will be unable to give blood?

Answer:  Hello.  Yes unfortunately patients on propecia are not eligible as blood donors.  The reason is that there is a risk that the blood will be given to a pregnant female, which in turn could cause harm to the foetus.  You could consider going off propecia for 2 weeks before giving blood, it shouldn’t have much of an effect on your hair and you can resume treatment after words.
