    Valtrex vs acyclovir


    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. The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. In sub-Saharan Africa, the region hardest hit by the HIV-1 epidemic, HSV-2 prevalences of 30-50% have been seen in the general population with prevalence up to 90% in infected with HIV-1. Listing a study does not mean it has been evaluated by the U. HSV-2 is common in those with, or at risk for, HIV-1 infection, and HSV-2 reactivation increases HIV-1 acquisition and infectiousness. Sexual transmission is responsible for the vast majority of HIV-1 infections among adults worldwide. Recent studies have shown that suppression of HSV-2 has a sustained effect on lowering HIV-1 levels in blood plasma. New data have raised the question whether higher doses of HSV-2 suppressive therapy might be more effective at suppressing HIV-1 levels. Mugwanya K, Baeten JM, Mugo NR, Irungu E, Ngure K, Celum C. Acyclovir and valacyclovir, chosen for use in this study, are safe and effective treatments for decreasing the frequency of HSV-2 reactivation and shedding. High-dose valacyclovir HSV-2 suppression results in greater reduction in plasma HIV-1 levels compared with standard dose acyclovir among HIV-1/HSV-2 coinfected persons: a randomized, crossover trial. The standard dose of acyclovir is 400 mg twice a day. Changes in plasma human immunodeficiency virus type 1 RNA associated with herpes simplex virus reactivation and suppression.

    Valacyclovir (Valtrex, marketed by Glaxo Smith Kline) and acyclovir (Zovirax, marketed by Sanofi-Aventis) are used mainly for treatment of genital herpes. Both are antiviral drugs and can be taken orally to shorten herpes symptoms or to prevent this infection from recurring in healthy individuals. Acyclovir pills had been in use from 1991 and enjoying the status of a first-of-its-kind antiviral drug for genital herpes treatment, until Valtrex was approved by the US Food and Drug Administration (FDA) 4 years later in 1995. The valacyclovir vs acyclovir debate started since then and it still remains a matter of research interest as to which drug you can use to cope with herpes better. Valacyclovir advantages Valacyclovir has a number of key advantages over other similar antiviral medications. Clinical trials have shown that this drug has greater effectiveness in dealing with the herpes simplex virus (HSV) or the varicella zoster virus (VZV), compared to acyclovir or other drugs. Another plus factor of Valtrex is that it is probably the only medicine that can reduce the risk of herpes transmission, given that safe sex methods are used. Nongenital herpes simplex virus type 1 is a common infection usually transmitted during childhood via nonsexual contact. 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. The differential diagnosis of nongenital herpes simplex virus infection includes aphthous ulcers, acute paronychia, varicellazoster virus infection, herpangina, herpes gestationis (pemphigoid gestationis), pemphigus vulgaris, and Behçet syndrome. Oral acyclovir suspension is an effective treatment for children with primary herpetic gingivostomatitis.

    Erectile dysfunction is a very common condition, one which affects most men at some point in their lives. The most popular treatment for it is Viagra, which means there are an awful lot of men out there trying to buy the medicine. However, it is not always obvious how and where you can buy Viagra, especially as erectile dysfunction and how to obtain treatment for the condition are unlikely to be topics you discuss with your mates down the pub. So, for those looking for a bit of guidance, here are some tips on where and how to buy Viagra safely: Although buying medicines over the counter is convenient, this is not usually an option for prescription-only medication like Viagra. In order to buy an erectile dysfunction medicine in a pharmacy, you usually need to have a prescription from a doctor. This is because Viagra can be dangerous if taken by men who are not medically suitable for it. Some pharmacies in the UK offer a Patient Group Direction, a protocol written by a doctor which enables a pharmacist or nurse to dispense a prescription-only medicine if a patient’s medical history is suitable.
