I am having a genital herpes outbreak. How many days should I take the antiviral valacyclovir 500mg (4 pills every 12 hours)?

The usual dosage for valacyclovir 500mg for genital herpes is 7 to 10 days. However, in some cases, it may be necessary to take it for up to 14 days if the lesions are not fully healed. The typical dose is 1g per dose, taken twice a day. So, instead of taking 4 pills at once, you would only take 2 pills each time.
