Valacyclovir exhibits better oral absorption and higher, more prolonged serum concentrations than oral acyclovir. The efficacy of valacyclovir and acyclovir on genital herpes simplex virus (HSV) shedding was assessed in a double-blind, 3-period crossover trial. Sixty-nine immunocompetent participants with genital HSV-2 received oral valacyclovir, acyclovir, and matching placebo in random order for 7-week periods. Participants provided daily genital mucosal swabs for HSV detection by viral culture and polymerase chain reaction (PCR). HSV was detected at least once in 62 (90%) participants by culture and in 68 (98%) by PCR. During placebo, the total HSV shedding rate was 15.4% of days by culture (PCR, 40.2%); the subclinical shedding rate was 6.6% by culture (PCR, 27.1%). Both antivirals were associated with lower HSV shedding by culture (relative risk [RR], 0.03 [95% confidence interval , 0.01–0.07] for valacyclovir and RR, 0.05 [95% CI, 0.03–0.10] for acyclovir) and PCR (RR, 0.18 [95% CI, 0.12–0.26] for valacyclovir and RR, 0.20 [95% CI, 0.15–0.28] for acyclovir), compared with placebo.

The lifelong infection affects 1 in 5 adults, and many infected people don't have symptoms and don't know they are infected. In the study heterosexual, monogamous couples were instructed to use condoms during sex. Previous research has shown that even when told to use condoms, many monogamous couples don't follow these instructions. Once-daily Valtrex cut the chance of the partner getting herpes with no symptoms by 50%. The risk of developing genital herpes with symptoms in the partner dropped by 77%. Previously, data were available only for patients who used daily valacyclovir for up to 12 months, Zane A. D., of the University of Washington, Seattle, and his colleagues reported in a poster at the annual meeting of the Infectious Diseases Society for Obstetrics and Gynecology. — Once-daily treatment with valacyclovir for the suppression of genital herpes caused by herpes simplex virus type 2 was well tolerated for up to 20 months in a recent study. For the current study, which was supported by Glaxo Smith Kline Inc., 1,484 serodiscordant, heterosexual, monogamous couples were enrolled, and the seropositive partner was randomized to receive either placebo or 500 mg/day of valacyclovir for 8 months. The results of this double-blind phase, which were previously reported by the investigators, showed that the treatment significantly reduced the risk of genital herpes transmission. Following the double-blind phase, 1,018 of the 1,484 participants treated in the double-blind phase entered an open-label suppression phase of the study, which provided 12 months of suppressive therapy with 500 mg/day of valacyclovir. Patients in this phase were evaluated every 3 months for laboratory values and adverse events. More than 85% of participants who completed the entire 20 months of treatment were at least 80% compliant with the study medication.
