Valacyclovir belongs to the class of medications known as antivirals. It is used to treat a viral infection affecting the skin known as shingles (herpes zoster). It is also used to treat cold sores, and to treat and prevent recurrences of genital herpes. It works by interfering with the way the virus reproduces. Valacyclovir works by stopping the virus from multiplying and spreading to nearby healthy cells. It does not cure shingles, cold sores, or genital herpes, but it does help the sores to heal more quickly, and it relieves pain and discomfort. When used to prevent recurrences of herpes, it also reduces the risk of transmission (spreading) of the infection to others. Presented in part at The American College of Obstetrics and Gynecology 45th Annual Clinical Meeting, Las Vegas, Nevada, 1997, where it received second place prize for papers on current clinical and basic investigation. Objective: To document the frequency of genital herpes recurrences in men and women with histories of recurrent genital herpes during 1 year of continuous, suppressive therapy with valacyclovir hydrochloride (HCl). Methods: In an open-label clinical trial conducted at 11 centers, 127 subjects (46 women and 81 men) with histories of recurrent genital herpes (at least 6 recurrences per year) were treated with valacyclovir HCl (500 mg once daily), and their clinical status was followed up for 1 year. Genital herpes recurrences were documented in diaries, and quarterly clinic visits were made for evaluating lesion recurrences and drug safety. In cases of recurrence, subjects self-treated with valacyclovir HCl 500 mg twice daily for 5 days, then resumed once-daily treatment. Results: After the first 3 months of suppressive therapy, 81% of subjects were free of recurrence. Recurrence-free rates remained undiminished during the second, third, and fourth quarters (84%, 84%, and 91%, respectively) and were similar for men and women.
