blood drive for me failed

There is a blood donation going on. After much struggle I decide to go for it. There after filling up the form, I told the counter person I am taking the propecia drug. They say I can't donate. I did ask my family doctor about blood donation but maybe I did not make it clear. Either way I am glad I told them about it. You wouldn't want someone's health issue tagged to you. Their form also never mention about other drugs. I am not sure I will be brave enough to try again since these things pains. At least I tried.
