Suppressive therapy reduces the frequency of genital herpes recurrences by 70 80 in patients who have frequent recurrences (345-348); many persons receiving such therapy report having experienced no symptomatic outbreaks. Safety and efficacy have been documented among patients receiving daily therapy with acyclovir for as long as 6 years and with valacyclovir or famciclovir for 1 year (350,351). 6 years and with valacyclovir or famciclovir for 1 year (350,351). It is also indicated for treatment of recurrent episodes of herpes simplex in HIV patients. Use of famciclovir in this manner has been shown to reduce the amount of latent virus in the neural ganglia compared to no treatment or treatment with valaciclovir.
Prevention strategies for sexual and perinatal transmission of HSV have not been well defined. Availability of type-specific serological tests for HSV antibodies may assist in identifying persons at risk for acquiring or transmitting HSV infection. Genital Herpes Infections: Treatment of Recurrent Episodes: Famciclovir was studied in two placebo-controlled trials of 626 otherwise healthy patients with a recurrence of genital herpes who were treated with famciclovir 125 mg b. Animal vectors for human HSV infections have not been described, and humans remain the sole reservoir for transmission to other humans. As compared with recurrent episodes of genital herpes, first episodes of genital herpes infection may have associated systemic symptoms, involve multiple sites including nongenital sites, and have longer lesion duration and viral shedding (49). Isolation of HSV by culture remains the definitive diagnostic method of documenting an HSV infection, including establishing neonatal HSV disease.

Episodic treatment of recurrent genital herpes is of questionable benefit, but it may be helpful in appropriately selected patients. 11 Mechanism and efficacy are similar to those of acyclovir.12 Famciclovir’s intracellular half-life is 10 times longer than acyclovir’s; despite this, dosing less frequently than twice daily is not recommended. Differences in shedding rates between genders have not been identified. Double-blind placebo-controlled trial of oral acyclovir in first-episode genital herpes simplex virus infection. Acyclovir, valacyclovir hydrochloride, and famciclovir are the 3 antiviral drugs routinely used to treat symptomatic herpes simplex virus (HSV) infections. A first episode of genital or oral herpes in a patient already seropositive for HSV is termed a nonprimary initial infection, and these infections tend to be less severe. For instance, famciclovir decreases lesion healing time by 2 days, efficacy that has not been demonstrated with topical therapy. Moreover, the higher dosage was effective in healing established lesions in men, even when initiated after the prodromal period.
