Zovirax Dosage: An Introduction

The dose of Zovirax® (acyclovir) that your healthcare provider recommends will vary, depending on a number of factors, including:
  • Your age and weight

  • Other medical conditions you may have.
As is always the case, do not adjust your Zovirax dose unless your healthcare provider specifically instructs you to do so.

Zovirax Dosage for Genital Herpes

The dose of Zovirax you are prescribed for genital herpes depends on whether it is your first infection, a subsequent infection, or you take Zovirax to prevent outbreaks.
First Infection
The recommended dose of Zovirax for treating the first infection of genital herpes is Zovirax 200 mg five times a day (about every four hours) for 10 days.
Later Outbreaks
For treatment of later outbreaks of genital herpes (after the first infection), the dose is Zovirax 200 mg five times a day (about every four hours) for five days, starting at the very first signs of an outbreak. The earlier it is started, the better it works.
