Safety profiles of valacyclovir (⩽1000 mg/day), acyclovir (800 mg/day), and placebo were similar.

Valacyclovir is used to treat viral infections caused by a group of viruses called herpes simplex viruses. These infections include oral and genital herpes, shingles, and chickenpox. Valacyclovir (generic for Valtrex) is a medication approved by the FDA to treat different types of herpes infections including HSV-1 and HSV-2.

To Treat Or Abort An Outbreak When There Are Early Symptoms (Prodrome): For both genital and oral herpes, people can take medication when their specific prodrome tells them an outbreak is about to occur. The medication will stop an outbreak cold (often) and when it does not, it can shorten the outbreak and make it milder than it might have been otherwise. To Prevent Outbreaks When There Are No Symptoms But Outbreaks Are More Likely: Patients also learn the life circumstances or behaviors that lead to more outbreaks. For some, a lack of sleep, increased alcohol, another illness, stress, too much sunlight, irritation, or anything that can affect one’s immunity can spur an outbreak. That means that some patients can know not just when they feel an outbreak coming on but can know when they are more likely to have an outbreak due to their circumstances. They might be under stress, having more sex therefore causing more physical irritation, drinking a bit more than they should, or missing sleep over an extended period.
