Tag: Breakthrough outbreak

According to the Centers for Disease Control and Prevention (CDC), suppressive therapy with valacyclovir can reduce genital herpes outbreaks by 70 to 80 percent, but it does not eliminate the possibility of a breakthrough episode. Many factors influence whether you can still have an outbreak while on valacyclovir, from viral mechanics to environmental triggers.

Studies show that daily valacyclovir can reduce genital herpes outbreaks by 70% to 80%, but it is possible to have an outbreak while taking valacyclovir daily. This phenomenon, known as a breakthrough outbreak, can be confusing for those on suppressive therapy who expect complete protection.
