Your doctor may prescribe an antiviral medication for you to take on a regular basis, if you develop cold sores frequently or if you're at high risk of serious complications.

To help avoid spreading cold sores to other people or to other parts of your body, you might try some of the following precautions:

  • Avoid skin contact with others while blisters are present. The virus spreads most easily when there are moist secretions from the blisters.
  • Be careful about touching other parts of your body. Your eyes and genital area may be particularly susceptible to spread of the virus.
  • Avoid sharing items. Utensils, towels, lip balm and other items can spread the virus when blisters are present.
  • Keep your hands clean. Wash your hands carefully before touching another person when you have a cold sore.
