What Is Valacyclovir

Valacyclovir is a prescription antiviral medication used to treat infections caused by herpes viruses. It is a prodrug that is converted to acyclovir in the body. Valacyclovir offers significantly better absorption than acyclovir, allowing for less frequent dosing and higher concentrations of the active drug in the body. This makes it a convenient option for both treatment and suppression of herpes infections.

Key Uses

Treatment of Herpes Zoster (Shingles): Valacyclovir is used to treat acute herpes zoster infections (shingles), helping to speed healing, reduce pain, and shorten the duration of symptoms.

Treatment of Genital Herpes: Valacyclovir is used to treat initial and recurrent episodes of genital herpes, helping to reduce the severity and duration of outbreaks.

Suppressive Therapy for Genital Herpes: Valacyclovir is used as suppressive therapy to prevent genital herpes outbreaks from coming back. Daily dosing reduces the frequency of recurrences and may lower the risk of transmission to partners.

How Valacyclovir Works

Valacyclovir is a prodrug that is converted to acyclovir in the body. Acyclovir works by inhibiting viral DNA replication, stopping the virus from multiplying and spreading to healthy cells. As a suppressive therapy, valacyclovir maintains antiviral levels in the body to suppress viral activity and prevent recurrent outbreaks.

Enhanced Absorption: Prodrug formulation allows for convenient, less frequent dosing.
