Patient discussion about Propecia

Q. i wan't to know. what are the side effects of propecia pills. and more about them please

A. my dad took it.. it helped a bit- but not too much. as i recall the side effects his prescribing Dr. was worried about were allergic reactions (skin rash, problem breathing, edema). but he said it can cause impotence and even breast cancer at men! he told him to check his breast for lumps every now and then.

Q. Do you know if Propecia can truly stop hair loss and even grow back hair. do you have any statistics about it? do you know if there are any side effects to this medication?

A. it does work but there is some side affects, as in E.D. while you are on the med.
