Study Summary

The purpose of this study is to examine the effects of valacyclovir in patients who have chronic hepatitis C, antibodies to herpes simplex type 1 infection but do not have antibodies to herpes simplex type 2 infection. Herpes simplex type 1 infection commonly causes cold sores or fever blisters, also known as herpes labialis, but most persons do not have any symptoms at all. Valacyclovir is a medication which is approved by the Food and Drug administration to treat herpes labialis. Valacyclovir has not been approved to treat chronic hepatitis C infection. The study will take 16 weeks. Participants will be assigned to take either the study drug, valacyclovir, or a sugar pill that looks exactly like valacyclovir. The researchers and patients will not know which medication they are receiving. Study visits will occur every two weeks and will take approximately 30-45 minutes. All study visits will occur at the G.V. Sonny Montgomery VA Medical Center in Jackson, Mississippi.
