Daflon 500mg Tablets for Erectile Dysfunction?

I suspect your problem is mostly neurological, but you need to see a urologist too. I don't see daflon helping you.

Daflon 500 mg is a prescription-only oral phlebotropic drug indicated in the treatment of venous disease--all conditions related to or caused by veins that become diseased or abnormal--and hemorrhoidal disease, which is dilated veins caused by increased pressure in the rectum.

The Daflon 500 product pamphlet says it is highly effective in the treatment of chronic hemorrhoidal disease and in reducing the frequency, severity and duration of severe hemorrhoidal attacks.
