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. 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.

Genital herpes (GH) recurrences and viral shedding are more frequent in the first year after initial HSV-2 infection. A daily swab of the genital/anal-rectal area was self-collected for HSV-2 detection by PCR. Subjects attended the clinic for routine study visits and GH recurrence visits. Treatment differences were assessed using a nonparametric crossover analysis. 52 subjects had at least one PCR measurement in both treatment periods and comprised the primary efficacy population. Valacyclovir significantly reduced HSV-2 shedding during all days compared to placebo (mean 2.9% versus 13.5% of all days (). In this study, the frequency of total and subclinical HSV-2 shedding was greater than reported in earlier studies involving subjects with a history of symptomatic genital recurrences. Our study is the first to demonstrate a significant reduction in viral shedding with valacyclovir 1 g daily compared to placebo in a population of subjects newly diagnosed with HSV-2 infection. The dose in immunocompromised patients is 1000 mg three times daily for at least seven days (3000 mg total daily dose) and for 2 days following crusting of lesions. This dose should be reduced according to creatinine clearance (see Renal impairment below). For recurrent episodes, treatment should be for three to five days. For initial episodes, which can be more severe, treatment may have to be extended to ten days. For recurrent episodes of herpes simplex, this should ideally be during the prodromal period or immediately upon appearance of the first signs or symptoms. Valtrex can prevent lesion development when taken at the first signs and symptoms of an HSV recurrence. For herpes labialis (cold sores), valaciclovir 2000 mg twice daily for one day is effective treatment in adults and adolescents. The second dose should be taken about 12 h (no sooner than 6 h) after the first dose.

Despite the efficacy of acyclovir and valacyclovir in reducing herpes genital lesions, antiviral therapy decreases the risk of transmission by only 48%. The high prevalence of HSV-2 continues to be a worldwide public health issue, and it has recently come to light that most reactivation, or “shedding,” episodes of the chronic infection caused by HSV-2 occur much more frequently than once thought. Valacyclovir given in a 5-day regimen of 500 mg twice per day is effective as short-term treatment of episodes of recurrent genital herpes. This study compared the efficacy of a shorter, 3-day course (for 402 patients) with that of a 5-day course (for 398 patients) of valacyclovir for persons with frequent recurrence of symptoms. No significant differences were detected between the 2 dosing schedules for any of the end points measured. Median times to lesion healing, of pain duration, and of episode length for the 5-day versus 3-day treatment were 4.7 versus 4.4 days, 2.5 days versus 2.9 days, and 4.4 days versus 4.3 days, respectively. The proportions of patients with aborted lesions were 26.6% and 25.4% in the 5-day and 3-day groups, respectively. A 3-day course of 500 mg of valacyclovir administered twice daily as episodic treatment of recurrent genital herpes is equivalent to a 5-day course with regard to key markers of efficacy.
