Sexual transmission of herpes simplex virus type 2 (HSV-2) has been demonstrated from both symptomatic and asymptomatic reactivations in the infected partner. Daily antiviral therapy has been shown to decrease the frequency and amount of genital HSV shedding. Corey and colleagues tested daily valacyclovir for efficacy in preventing sexual transmission of HSV-2 from infected persons to their uninfected partners. The study enrolled monogamous, immunocompetent, heterosexual couples in which only one partner was infected with HSV-2, as demonstrated by Western blot analysis of anti–HSV-2 serum antibodies. Of the initial 4,034 couples screened, 1,385 asymptomatic partners already had serologic evidence of HSV-2 infection and were ineligible, and 799 of the source partners were symptomatic but had negative HSV-2 serology. After informed consent, 352 couples declined to participate, and 14 persons declined to take the study medicines, leaving 1,484 couples (37 percent) available for randomization. The infected source partner of each enrolled couple was randomized to receive valacyclovir in a dosage of 500 mg or placebo taken once daily for eight months. tadalafil tablets 20 mg The following information is NOT intended to endorse drugs or recommend therapy.
