What to do if I have hepatitis C and interferon did not work.?

Hep C Rx. Treatment options include: Direct antiviral agents (DAA's). DAA's are a group of different antiviral agents taken orally for a much shorter period of time than the other medications and will probably revolutionize the treatment of Hep C. Both new pills - Olysio (simeprevir) and Sovaldi (sofosbuvir) - work better than the current treatment for hepatitis C. They cure it more often & in less time.
