Valtrex (valacyclovir) is an antiviral medication used to treat infections with: 1  herpes zoster (shingles), 2  herpes simplex genitalis (genital herpes), 3  and herpes labialis (cold sores).
Herpes viruses are responsible for both cold sores and genital herpes. Valtrex can also be prescribed to shorten the duration and severity of chickenpox outbreaks in adults. While Valtrex does not cure the herpes infection, it usually makes the outbreaks less severe and shorter.altrex has another long-term use that doesnât have to do with the same herpes virus that causes cold sores and genital herpes. This virus, called cytomegalovirus (CMV), is a related virus that can also lie dormant in the body for long periods of time.
