In people with frequent outbreaks, this medication is used to reduce the number of future episodes. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching.

A total of 922 immunocompetent outpatients were treated with either regimen for 5 days; treatment was self-initiated at the first symptoms of the next recurrence. The principal outcome measures were the percentage of lesions healed at day 6, time to healing, time to cessation of pain, discomfort or itching, the percentage of abortive episodes and safety. Equivalence was assessed by comparison of 80% confidence limits for each measure; the two regimens were regarded as equivalent if the lower confidence limit was higher than a pre-determined equivalence limit calculated to show a maximum 10% inferiority of valacyclovir 1000 mg od against valaciclovir 500 mg bd. Intention-to-treat analysis showed that the two treatments were equivalent for each outcome measure.
