Indications and Uses:
- Herpes Simplex Virus (HSV) Infections: Valacyclovir is used to treat herpes labialis (cold sores) and genital herpes infections. It helps reduce the duration, severity, and frequency of outbreaks.

How Does Valacyclovir Work?
Valacyclovir works by inhibiting the replication of the herpes virus, thereby reducing the severity and duration of outbreaks. Once inside the body, valacyclovir is converted to its active form, acyclovir. Acyclovir acts by blocking the viral DNA replication process, preventing the virus from multiplying and spreading.
