    Valacyclovir for herpes zoster


    Reactivation of varicella-zoster virus (VZV) that has remained dormant within dorsal root ganglia, often for decades after the patient’s initial exposure to the virus in the form of varicella (chickenpox), results in herpes zoster (shingles). Although it is usually a self-limited dermatomal rash with pain, it can be far more serious; in addition, acute cases often lead to postherpetic neuralgia (PHN) and is responsible for a significant economic burden. See 15 Rashes You Need to Know: Common Dermatologic Diagnoses, a Critical Images slideshow, for help identifying and treating various rashes. The clinical manifestations can be divided into the following three phases: Diagnosis is based primarily on the history and physical findings. In most cases, confirming the diagnosis via laboratory testing has no utility. In select patient populations, however—particularly immunocompromised patients—the presentation can be atypical and may require additional testing. Steroid treatment is traditional but controversial. Typically, a substantial dose (eg, 40-60 mg of oral prednisone every morning) typically is administered as early as possible in the course of the disease and is continued for 1 week, followed by a rapid taper over 1-2 weeks. The Herpesviridae family (Types 1-8) continues to inflict considerable morbidity and social stigma upon humanity. Once infected with the herpes viruses, especially Types 1-3, they establish permanent residence within our nervous system and reactivate during periods of stress, trauma, and/or other precipitating factors. To date, there is no cure for herpes viral infections but antivirals can attenuate the symptoms and duration of episodic outbreaks. The first antiviral with selective activity against virus-infected cells is considered to be acyclovir. Our article will highlight the clinical indications of the current generation, valacyclovir, which is a prodrug of acyclovir. We consider valacyclovir as a second-generation antiviral, having taken into account the initial selectivity and safety profile of its progenitor, acyclovir. The hallmark of the herpes viruses is their ability to establish permanent residency within the neuronal ganglia of our nervous system and to reactivate during times of stress, trauma, and other precipitating factors. The herpes simplex virus-1 (HSV-1), herpes simplex virus-2 (HSV-2), and varicella-zoster virus (VZV) can be associated with painful, blistering outbreaks that, although they are self-limiting, have been associated with considerable morbidity.

    Valacyclovir is a drug that is used to control the herpes virus. This virus is responsible for shingles, herpes simplex genitalis and cold sores. Valacyclovir will stop the replication of viral DNA which will reduce the reproduction of herpes virus. This drug will not kill the herpes virus but will only help control the many symptoms of herpes. Valacyclovir is converted into acyclovir in the body which is also another antiviral medication. Compared to taking acyclovir doses, valacyclovir has a longer duration. Acyclovir on the other hand is available in other forms like intraveneous and topical doses. The aim of this Cochrane Review was to find out if valacyclovir performs better than acyclovir in the treatment of a painful itchy rash caused by the chickenpox virus (herpes zoster ophthalmicus). Cochrane researchers collected and analysed all relevant studies to answer this question and found one ophthalmicus is a painful itchy rash that appears on one side of the forehead. If the rash reaches the eye it may lead to visual impairment. This is because the infection can damage the front of the eye. is caused by the chickenpox virus, which can remain in the body for many years after the original chickenpox infection, and may get reactivated. Doctors can treat herpes zoster ophthalmicus with acyclovir. This is an antiviral medication that kills the chickenpox virus.
