Valtrex

Valtrex contains valacyclovir (or valaciclovir). It’s an antiviral drug, used to treat infections or reduce the symptoms of diseases caused by certain viruses.

However, the drug helps in reducing the length and severity of the viral infection outbreaks and helps sore heal faster while preventing new sores from developing.
