I am taking viekira pak because insurance would not cover Harvoni. I am undetectable after 8 weeks. I must stay on it for 24 weeks due to cirrhosis. I tried interferon 10 yrs ago and it obviously did not work. The side effects kicked my ass, I am very grateful that it is working but all the hype about the new medications not having side effects are not true. I am much sicker than I was on interferon. I bring this up to let people know that they should really fight to get the Harvoni because I've heard nothing but good stuff about it, that it barely has any side effects. I know of people who walked off treatment when they were found on detectable but due to getting educated about Hep C from this blog and from other sources I know that that would be a Huge mistake I will keep on keeping on.
