    The objective of this multicenter, randomized, double-blind, noninferiority trial was to investigate valacyclovir as treatment for facial herpes simplex virus (HSV) outbreaks. In total, 308 otherwise healthy outpatients self-initiated therapy with valacyclovir, either 1000 mg twice daily for 1 day or 500 mg twice daily for 3 days, for treatment of one facial HSV episode. Secondary end points included episode and pain resolution and lesion healing. By regimen (1 or 3 days), aborted lesions occurred in 42.2% versus 46.7% of patients, treatment difference, −4.5% (95% confidence interval, −16.3% to 7.4%; P=.49). Subgroup findings showed that about half the episodes aborted when therapy started during the prodrome/macule stages or within 6 h of first symptoms. Episode and pain resolved rapidly, with results similar for both treatments. Adverse events were infrequent and similar for the two regimens Most of the focus on improving the treatment of facial herpes simplex virus (HSV) infection, particularly herpes labialis, has been directed toward topical therapies, including those with a specific antiviral mechanism of action. Key contributing factors to this focus include the ease of access to such products in many countries, especially those that do not require a physician’s prescription, the ability of most patients to recognize a pending facial herpes outbreak from an early age, and the readily visible anatomic sites affected for application of topical therapy. Corneas were inoculated with HSV-1, and latent infection was allowed to establish. Starting on postinoculation (PI) day 28, tear swabs were collected once daily for 6 consecutive days before treatment. The rabbits were placed in five balanced groups: group 1 had no treatment, group 2 received placebo, group 3 received 7 mg/kg VCV, group 4 received 70 mg/kg, and group 5 received 140 mg/kg. The treatment was administered by oral gavage twice daily, starting on PI day 36 and continuing for 14 days. The ocular swabs were collected beginning on PI day 40 and continuing for 10 days. The mean copy number of HSV-1 DNA before treatment was 370 ± 70, 569 ± 273, 368 ± 86, 408 ± 108, and 396 ± 91, and the mean HSV-1 DNA copy number after treatment was 232 ± 183, 564 ± 186, 518 ± 122, 67 ± 63, and 13 ± 7 in groups 1 to 5, respectively. The 70- and 140-mg/kg doses of VCV significantly reduced the HSV-1 DNA copy number, compared with that of the other three groups. A daily dose of 500 mg (∼7 mg/kg) VCV in healthy human volunteers did not suppress HSV-1 DNA shedding in tears and saliva.
