Drug Class and Mechanism

Valtrex is an antiviral. It works by stopping viral replication. However, Valtrex does not eliminate the virus, it is not a cure. When used as a suppressive therapy in patients with normal immune systems with genital herpes using safer sex practices, the risk of spreading the infections to others is reduced.
