Downsides

  • Zovirax (Acyclovir) is not a cure for herpes, chickenpox, or shingles. It will only shorten the time you have a breakout.
  • If you're taking Zovirax (Acyclovir) for herpes, you should use barrier methods (condoms) when you're having sex since you can still pass it on to other people, even if you're taking the medication and you're not in a breakout.
  • You need to take this up to five times a day, so it can be inconvenient.
