In 1998 I did six months interferon w/ribavirin through dosage level study with Virgina Hepatitis Study Group, but then not clear. I do recall an early
reduction of 6.5m to 600k. Later in 2002 started peginterferon w/ribavirin, but stop at week 12 due to not have two-log drop.
Both times I had what I would state was noteworthy rash. However, got through it via powders, lotions, etc.....
