Sildenafil and tadalafil are the two most widely prescribed treatments for erectile dysfunction. Both help most men who try them, and both are now available as cheaper generics. The question that matters is usually not which one is "better", but which one suits the way you live.

Generic tadalafil, on the other hand, can last for up to 36 hours, and food get more info makes little difference. Many men also take a low daily dose of tadalafil so they never need to time a tablet.
