Antiviral Used for Outbreak or Suppression

​

Valacyclovir is an antiviral medication used to treat and suppress infections caused by viruses like herpes simplex virus (HSV) and varicella-zoster virus (VZV). It starts working quickly to shorten healing time for cold sores and shingles outbreaks. It lessens symptoms like pain, itching, and burning for both cold sores and genital herpes. It can also be used to decrease the frequency of future outbreaks for genital herpes. Treatment is often just a short course. (e.g., one-day regimen for cold sores).
