Hi I took Sovaldi, Pegasys, Ribaviran, and I took them all on day 1, the Sovaldi and part of the
Ribavirin in the morning, the second half of the
Ribavirin and shot #1 in the evening, I think it is important to take them all on the first day, as they all work together. The shots mark the beginning of each week. You can always give Sovaldi a call to ask also. Good luck!
