    Valtrex prevention


    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. can sildenafil be taken daily It is a pro-drug of aciclovir (Zovirax), meaning that it is broken down into aciclovir within the body. Valaciclovir produces higher blood levels of the active drug than is possible using the conventional tablet formulation of aciclovir. Valaciclovir was formerly known by the codename BW256U87, and is known by the generic name netivudine. In February 1995, an international study testing valaciclovir and high doses of aciclovir as preventive treatment for cytomegalovirus was stopped seven months early because participants who received valaciclovir were more likely to develop side-effects and had a significantly higher death rate, possibly due to higher levels of active drug. However, since valaciclovir was taken for a shorter period than aciclovir, there was no difference between the two arms once the full follow-up period of the study was completed. However, valaciclovir is effective in preventing cytomegalovirus in patients with HIV. A study of 310 patients with advanced HIV disease found that the drug lowered cytomegalovirus levels in the blood, delaying the onset of disease to a greater extent than aciclovir. In HIV-positive people, a dose of 1000mg twice daily was shown to be comparable to 200mg aciclovir five times daily in treating a single episode of genital herpes, while 500mg twice daily was superior to placebo in preventing or delaying recurrences. Valaciclovir appears to be linked to a potentially fatal type of bleeding in the kidneys, known as haemolytic uraemic syndrome.

    Genital herpes is a chronic, life-long viral infection. 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. Since genital herpes (HSV-2) is sexually transmitted, safer sex practices can go a long way in preventing both infection and transmission. Cold sores, or oral herpes (HSV-1), can be harder to prevent, as they are usually spread by casual contact, though there are strategies that can help. If you are already infected with a herpes simplex virus, you can also reduce the frequency of symptomatic recurrences. While no one wants herpes, it is especially important to prevent oral or genital HSV infections if you have an immune deficiency. These conditions can be more severe if your immune system is not functioning as it should. If you are pregnant or thinking about becoming pregnant, you should be vigilant about preventing genital HSV infection because it can be transmitted to your baby during vaginal delivery, potentially causing serious problems. While the prevention of genital herpes may be on your mind if you or a partner have already been diagnosed, anyone who is sexually active should be mindful of the risk of transmission, especially since many people with HSV-2 have no symptoms at all.
