Information about Valtrex (Valacyclovir)
Valtrex is an antiviral medication containing valacyclovir, which is converted into its active form, acyclovir, in the body. It is used to treat a variety of viral infections caused by the herpes simplex virus (HSV) and varicella-zoster virus (VZV). Valtrex works by inhibiting viral DNA replication, thereby slowing the growth and spread of the virus. It is most commonly used to treat conditions like herpes simplex infections (cold sores, genital herpes) and shingles.
