Herpes simplex virus infection is increasingly common in the United States. New antiviral medications have expanded treatment options for the two most common cutaneous manifestations, orolabial and genital herpes. Acyclovir therapy remains an effective and often less expensive option. Famciclovir and valacyclovir offer improved oral bioavailability and convenient oral dosing schedules but are more expensive than acyclovir. Patients who have six or more recurrences of genital herpes per year can be treated with one of the following regimens: acyclovir, 400 mg twice daily; valacyclovir, 1 g daily; or famciclovir, 250 mg twice daily. These regimens are effective in suppressing 70 to 80 percent of symptomatic recurrences. Episodic treatment of recurrent genital herpes is of questionable benefit, but it may be helpful in appropriately selected patients. viagra y sus efectos An extensive clinical trial program combined with 5 years’ postmarketing experience with valacyclovir provides evidence of favorable safety and efficacy in herpes simplex virus (HSV) management. Valacyclovir enhances acyclovir bioavailability compared with orally administered acyclovir. Long-term use of acyclovir for up to 10 years for HSV suppression is effective and well tolerated. Acyclovir is also approved for use in children, is available in some countries over the counter in cream formulation for herpes labialis, and has been monitored in over 1000 pregnancies. Safety monitoring data from clinical trials of valacyclovir, involving over 3000 immunocompetent and immunocompromised persons receiving long-term therapy for HSV suppression, were analyzed. Safety profiles of valacyclovir (⩽1000 mg/day), acyclovir (800 mg/day), and placebo were similar. Extensive sensitivity monitoring of HSV isolates confirmed a very low rate of acyclovir resistance among immunocompetent subjects ( Five years after the licensing of valacyclovir and two decades after the introduction of acyclovir, a wealth of data has been generated on the clinical utility of this selective antiherpes agent and its prodrug.

Two types of HSV can cause genital herpes: HSV-1 and HSV-2. Most cases of recurrent genital herpes are caused by HSV-2, and approximately 50 million persons in the United States are infected with this type of genital herpes . Most persons infected with HSV-2 have not had the condition diagnosed. Many such persons have mild or unrecognized infections but shed virus intermittently in the anogenital area. As a result, most genital herpes infections are transmitted by persons unaware that they have the infection or who are asymptomatic when transmission occurs. Management of genital HSV should address the chronic nature of the disease rather than focusing solely on treatment of acute episodes of genital lesions.
