    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.

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.

    Hi sweetie, Im no doctor but I found this very intersting hope it helps. Amoxicillin (Amoxil®, Moxatag™) is a prescription antibiotic. The specific effects of an amoxicillin overdose will vary, depending on a number of factors, including the amoxicillin dosage and whether it was taken with any other medications or substances. Effects of an Amoxicillin Overdose A mild amoxicillin overdose probably will not cause any significant or lasting problems. However, a large overdose could affect the kidneys, possibly causing poor kidney function or even kidney failure. It is also reasonable to expect that an overdose would cause any of the usual amoxicillin side effects, but perhaps more severely. For instance, it is possible that nausea, vomiting, and diarrhea would occur. Treatment for an Amoxicillin Overdose The treatment for an amoxicillin overdose will vary. If the overdose was recent, a healthcare provider may administer certain medicines or place a tube into the stomach to "pump the stomach." Treatment also involves supportive care, which consists of treating the symptoms that occur as a result of the overdose.
