Abstract in brief

  • High-dose, short-duration valacyclovir therapy effectively reduces the duration and severity of cold sore outbreaks when taken at the first sign of symptoms, based on two randomized controlled studies.
  • The studies show that a 1-day regimen of valacyclovir not only shortens the duration of episodes but also increases the chances of preventing or blocking lesion development, with minimal side effects.
  • This research supports the use of a simple, safe, and convenient one-day oral treatment as an alternative to topical therapies for herpes labialis (cold sores).]

@Eveliciosa @whateveriwant Hay dosis “profilácticas” pero un aciclovir es muy poco. Está estudiado que antes de que te salga si te tomas valaciclovir 2 g/12 hrs por un día debería evitar que salga (High-dose, short-duration, early valacyclovir therapy for episodic treatment of cold sores.
