Listen,
My situation is getting complicated each day

. I have been ON and OFF
Ziac for the last few months in order to see if it causing me some side effects. Anyway, I can't answer your question

, sorry man but it's very difficult to answer that. As I said there are many things that can contribute to your ED.
For me I don't think that
Ziac will make ED, I say that because today I knew that I have another issue that causes ED. Anyway, still while you take it it reduces you by 10% or even 5%.
You don't have to worry at all

, just stay away from Beta-Blockers and use an ARB drug like Cozaar, Atacand or Diovan because it has no effect on sexual ability. Also they said that Norvasc is fine too.
Don't worry and forget about it ok?
Good Luck,
Michael
