Broken Blisters: Home Treatment - Topic Overview

  • After you have drained a blister, or if it has torn open:
    • Wash the area with soap and water. Do not use alcohol, iodine, or any other cleanser.
    • Don't remove the flap of skin over a blister unless it's very dirty or torn or there is pus under it. Gently smooth the flap over the tender skin.
    • Apply an antibiotic ointment and a clean bandage. If the skin under the bandage begins to itch or a rash develops, stop using the ointment. The ointment may be causing a skin reaction.
    • Change the bandage once a day or anytime it gets wet or dirty. Remove it at night to let the area dry.

Watch for a skin infection while your blister is healing. Signs of infection include:

  • Increased pain, swelling, redness, or warmth around the blister.
  • Red streaks extending away from the blister.
  • Drainage of pus from the blister.
  • Fever.
