Once daily valacyclovir for reducing viral shedding in subjects newly diagnosed with genital herpes.

Objective: Genital herpes (GH) recurrences and viral shedding are more frequent in the first year after initial HSV-2 infection. The objective of this study was to provide the first evaluation of valacyclovir 1 g once daily compared to placebo in reducing viral shedding in subjects newly diagnosed with GH.

Methods: 70 subjects were randomized to receive valacyclovir 1 g daily or placebo in a crossover design for 60 days with a 7-day washout period.

The effect of daily valacyclovir suppression on herpes simplex virus type 2 viral shedding in HSV-2 seropositive subjects without a history of genital herpes.

Background: A substantial number of HSV-2 seropositive individuals lack a history of clinically recognized genital herpes. These individuals can transmit disease during periods of asymptomatic viral shedding. The frequency of asymptomatic shedding and the efficacy of antiviral therapy in reducing shedding has not been assessed in this population.

Efficacy and safety of valacyclovir for the suppression and episodic treatment of herpes simplex virus in patients with HIV.

Three randomized controlled trials of valacyclovir for the management of recurrences of genital herpes in HIV-infected persons were conducted between 1991 and 2002. One study evaluated episodic therapy for the treatment of genital herpes, and 2 studies evaluated continuous suppressive therapy. Valacyclovir at 1000 mg twice daily for 5 days was comparable to acyclovir at 200 mg 5 times daily in accelerating healing of a single episode of genital herpes (hazard ratio, 1.

Valacyclovir for the suppression of recurrent genital herpes in human immunodeficiency virus-infected subjects.

To determine the efficacy and safety of valacyclovir (500 mg twice daily) for the suppression of recurrent genital herpes simplex virus infections in human immunodeficiency virus (HIV)-infected subjects, a randomized, double-blind, placebo-controlled, multicenter international trial was conducted. A total of 293 HIV-seropositive subjects receiving antiretroviral therapy were enrolled. The proportion of subjects who did not have a recurrence of genital herpes at 6 months was 65% among valacyclovir recipients versus 26% among placebo recipients (relative risk, 2.
