Valacyclovir (Valtrex) – Antiviral Medication

Valacyclovir is an oral antiviral medication active against herpesviruses. In the body it is rapidly converted into acyclovir, a compound that inhibits herpesviral DNA replication. Valacyclovir is used to treat infections caused by herpes viruses:

• Cold sores (herpes labialis): Shortens the course of outbreaks and speeds healing.
• Genital herpes: Treats initial and recurrent outbreaks of genital herpes; it is also used as daily suppressive therapy to reduce recurrences and transmission.
• Shingles (herpes zoster): Reduces duration and pain of shingles outbreaks.
• Chickenpox (varicella) in children: Used to lessen symptoms and speed recovery in pediatric chickenpox cases.

Valacyclovir does not cure the underlying herpes infection, but it reduces symptoms – relieving pain and itching, and helping sores heal faster. It is available by prescription (for example, under the brand name Valtrex®).
