Genital herpes is caused by herpes virus infection, mostly caused by herpes virus type 2 infection. If the recurrence is more than 6 times a year, it is called frequent recurrence, when long-term suppressive therapy can be used, such as acyclovir 400 mg orally twice a day, or valacyclovir 300 mg orally once a day, or you can give famciclovir 125-250 mg orally twice a day, which needs to be given continuously for a long time, and the course of treatment is usually four months to a year. If the attacks are not frequent and do not require long-term medication, antiviral drugs can be given orally before the rash appears and when there are prodromal symptoms, while paying attention to rest, avoiding stress and anxiety, and avoiding a decline in immunity.
