Valacyclovir is used to treat infections caused by certain types of viruses. In children, it is used to treat cold sores around 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. The viruses that cause these infections continue to live in the body even between outbreaks. Valacyclovir is also used to treat outbreaks of genital herpes. Valacyclovir decreases the severity and length of these outbreaks. In people with frequent outbreaks, this medication is used to reduce the number of future episodes. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching. This medication may also help reduce how long pain remains after the sores heal.
