Valtrex is a medication effective against several virus species that may cause bothersome viral disease symptoms. It contains Valacyclovir, which is a drug known for its ability to block virus growth and alleviate viral infection symptoms. The main medical reasons for using Valtrex are oral herpes infection, also known as herpes labialis, which is very sensitive to Valacyclovir, and the symptoms usually disappear within days. Herpes simplex or the genital version of the herpes viral infection is also effectively treated with Valtrex. It is important to take the drug when the first signs of herpes appear because it greatly improves the effectiveness of the antiviral therapy. The drug is also used to treat chicken pox and shingles, which are both caused by the varicella-zoster virus. Experimental usage against CMV and Epstein-Barr viruses has yielded great results so far, so in the near future the drug may be prescribed to treat viral infections caused by these viruses also. Valtrex does not cure herpes or varicella zoster because these viruses are able to remain in a latent, dormant state, and they multiplicate during the re-activation phases of the viral infection. However, Valtrex dramatically reduces the impact of the virus re-activation on the human body, ameliorates the symptoms and inhibits the growth of susceptible virus species.

How does Valtrex work on the biological level to block viral infections and reduce the annoying symptoms?
Once ingested and distributed in the bloodstream, Valtrex (Valacyclovir) passes through the liver and undergoes a chemical transformation that results in the formation of Acyclovir. In fact, Acyclovir is the substance that directly influences the susceptible virus species and inhibits their growth and development on a cellular level. Valacyclovir in its original state does not become active against viruses until it converts to Acyclovir in liver cells. After the conversion stage, Valtrex penetrates into the cells that have become infected with the virus and inhibits the viral DNA. The DNA inhibition is the most important phase in the entire process because it blocks the reproduction and multiplication of vulnerable virus species, which translates into gradually reduced viral infection symptoms and disease remission. The viral DNA replicates through a special enzyme DNA polymerase, which is responsible for making new viral copies that would infect other cells. Valtrex specifically inhibits this viral enzyme, which prevents a worsening of viral infection symptoms and gradual relief.
If you experience potential side effects after Valtrex administration, such as headaches, nausea or episodes of diarrhea, don’t hesitate to talk to your physician about them. These adverse effects are usually infrequent, and they diminish within days. If you experience other bothersome effects during Valtrex treatment, report them to a medical professional, and a dosage adjustment or an alternative therapy may be recommended.
