I was prescribed (diosmin+hesperidin) for hemorrhoids, is this safe to take w viagra (sildenafil). will it make my erectile dysfunction better or worse?

Why Viagra (sildenafil) at 40?: I'm more concerned about the erectile dysfunction of a 40 year old. I don't have your history, but i would be concerned about cardiovascular disease without other obvious causes for you ed. Start by visiting your md for a complete panel of tests to include cimt if possible. If that test is not available a calcium score will do. Ed is a major 'red flag' in a 40 year old.
