How Valacyclovir Hydrochloride works

  • Valacyclovir is an antiviral medicine that is converted in the body into its active form, acyclovir.
  • Acyclovir resembles a natural building block of DNA. Inside cells infected with herpes viruses, it is converted into its active triphosphate form, which blocks a viral enzyme called DNA polymerase.
  • By blocking this enzyme, Valacyclovir stops the virus from copying its DNA and multiplying. This helps control the infection, reduce symptoms, and speed up healing.
