Both Famvir (Famciclovir) and Valtrex (Valacyclovir) are antiviral medicines used primarily in the treatment of certain viral diseases like Genital Herpes, Herpes Labialis (Cold Sores), Herpez Zoster (Shingles) and Chicken Pox. Both of them are closely related to Aciclovir (Zovirax), which was the first antiviral drug to be successfully used in these viral diseases. Both Famvir and Valtrex are prodrugs, which get converted to another more active ingredient within the body cells. They are both taken orally, and used primarily for alleviation of symptoms and severity of the episode. However, in spite of their similar profile, there are certain important differences in their drug formulation, activity, efficacy and adverse effects which can decide as to which of them might be preferable in a particular patient. Famvir is the trade name under which Famciclovir compound is currently marketed by its manufacturer, Novartis Pharmaceuticals.

Most of these infections involve the oral mucosa or lips (herpes labialis). The diagnosis of an infection with herpes simplex virus type 1 is usually made by the appearance of the lesions (grouped vesicles or ulcers on an erythematous base) and patient history. However, if uncertain, the diagnosis of herpes labialis can be made by viral culture, polymerase chain reaction, serology, direct fluorescent antibody testing, or Tzanck test. Other nonoral herpes simplex virus type 1 infections include herpetic keratitis, herpetic whitlow, herpes gladiatorum, and herpetic sycosis of the beard area.

Infections by herpes simplex virus (HSV) cannot yet be eliminated, but the severity of the disease can be reduced. Two newer drugs with established efficacy for such infections, famciclovir and valacyclovir, were tested in a mouse eye model of HSV infection. Both drugs significantly reduced mortality and titers of virus shed from the eyes of mice infected with an otherwise lethal dose of HSV type 1 (HSV-1). Similar titers of HSV-1 were found in the eyes, ganglia, and brains of treated animals. Although valacyclovir reduced the latent viral DNA load better in these studies than did famciclovir, rates of reactivation by explantation and UV exposure were the same. Thus, in this study, famciclovir and valacyclovir were equally effective in limiting the virulence and spread of HSV-1, despite their biochemical and pharmacologic differences. Herpes simplex virus (HSV) types 1 and 2 are important human pathogens that cause orofacial and genital lesions . Genital herpes is a chronic, life-long viral infection. Two types of HSV can cause genital herpes: HSV-1 and HSV-2.
