Valacyclovir is used to treat cold sores (herpes labialis), shingles (herpes zoster). It is also used to treat genital herpes in patients with a normal immune system. Valacyclovir can also be used to control genital herpes outbreaks in all patients including those with HIV. This is also known as suppressive therapy. This medication helps control symptoms, but does not cure the disease. Valacyclovir belongs to a class of medications known as antivirals. If you are taking valacyclovir for treatment of genital herpes, to lower the chance of giving herpes to your partner, it is important to follow safe sex practices even if there are no symptoms present. Always use a condom made of latex or polyurethane. When you have symptoms or are experiencing an outbreak, do not have sexual contact with your partner.

This medication may be used to prevent or treat other types of viral infections (cytomegalovirus) in certain patient populations.

Read the Patient Information Leaflet available from your pharmacist. Consult your doctor or pharmacist if you have any questions. Take valacyclovir by mouth, as directed by your doctor, with or without food. When taking this medication to treat an outbreak, it works best if you take this medication when you first notice an outbreak is starting. The medication may not work as well if you wait more than 72 hours to start it. Dosage is based on your medical condition and response to therapy.
