When should I take valacyclovir after I feel a potential outbreak coming on?

It is important to take valacyclovir at the first sign of symptoms because there is no evidence that the medication works once lesions are visible. Most people will be able to tell when an outbreak is coming on. They may experience burning, itching, tingling, or other sensations that alert them to an imminent outbreak.

Taken at the earliest feelings that an outbreak is on the verge of occurring, valacyclovir may either stop the attack altogether or shorten how long it will last. Remember, with valacyclovir treatment for herpes, the earlier you take it after the symptoms appear, the better.
