Valacyclovir can be effective in treating genital herpes. The recommended dosage is either 500mg twice a day for 3 days or 1g (2 tablets of 500mg) for 5 days. It is most effective when taken early onset of symptoms. However, it does not reduce the risk of future outbreaks. To reduce recurrence of outbreaks, it is important to avoid triggers such as stress, friction, irritating hygiene products, and illness. In some cases, a doctor may prescribe a suppressive treatment to reduce the frequency of outbreaks. It's important to note that there is no cure for herpes, but symptoms can be managed.
