Valacyclovir is employed to treat infections triggered by certain kinds of viruses. In children, it is used to treat sores that are cold the mouth (caused by herpes simplex) and chickenpox (caused by varicella zoster). In adults, it is used to treat shingles (caused by herpes zoster) and cold sores around the mouth.
Valacyclovir can also be used to treat outbreaks of genital herpes. In people with frequent outbreaks, this medication is used to reduce the number of future episodes.
