Valtrex, also known as Valacyclovir, is an antiviral medication that inhibits the activity and multiplication of viruses, especially herpes simplex virus type I and II, and Varicella zoster virus. Its effectiveness in blocking the effects of other types of viruses, such as Cytomegalovirus (CMV) or Epstein-Barr virus (EBV), is also well documented, although its viral inhibitory activity is less intense for these virus species.
How Valtrex helps to stop Herpres
Valtrex is ingested or administered as a prodrug, meaning that is becomes active only when metabolized in the body by certain biological enzymes. Valacyclovir becomes active when it is converted in the human body to Acyclovir, which possesses the highest degree of antiviral activity and effects. Once the conversion of Valtrex to Acyclovir is accomplished, the active drug works by inducing the production of high amounts of Acyclo-GTP, which is a biologically active molecule that inhibits the viral DNA polymerase. Viruses such as herpes simplex or Varicella zoster employ the DNA polymerase enzyme to produce more virus copies, also known as viral multiplication. The cells that are infected with the virus become a source of viral multiplication through the creation of more viral copies that may infect other cells and sustain the bothersome symptoms of the viral infection. Valtrex is able to block the enzyme that is responsible for viral multiplication, which dramatically inhibits the growth and the spreading of the viral infection, also limiting its symptoms.

Valtrex is effective against both Oral and Genital Hepres
Valtrex or Valacyclovir is used to treat several varieties of viral infections, such as oral and genital-type of herpes simplex infection, prevention of herpes contamination of healthy individuals through lowering the number of viral copies, and herpes zoster infection, also known as shingles. Valtrex may be used as an effective antiviral drug in special medical situations, such as the prevention of CMV infection in individuals who undergo organ transplantation or the prevention of herpes infection in individuals with a weak immune system, such as those who are treated with chemotherapy drugs for cancer or individuals infected with AIDS. Although it is not yet a common medical indication for Valtrex, the drug is actively investigated as a potential treatment for infectious mononucleosis caused by the Epstein-Barr virus.
Although Valtrex is a safe, clinically tested and approved antiviral medication, it can cause certain side effects, most of which are temporary and mild. Adverse effects provoked by Valtrex may include nausea, vomiting, digestive disturbances, such as diarrhea or abdominal pain, and headaches. No substantial viral resistance to Valtrex has been documented in clinical practice. Don’t hesitate to benefit from solid medical advice offered by a certified physician before considering Valtrex as a potential treatment for oral or genital herpes simplex or herpes zoster infections.
