Blisters - Home Treatment

Most blisters heal on their own. Home treatment may help decrease pain, prevent infection, and help heal large or broken blisters.

  • A small, unbroken blister about the size of a pea, even a blood blister, will usually heal on its own. Use a loose bandage to protect it. Avoid the activity that caused the blister.
  • If a small blister is on a weight-bearing area like the bottom of the foot, protect it with a doughnut-shaped moleskin padcamera.gif. Leave the area over the blister open.
  • If a blister is large and painful, it may be best to drain it. Here is a safe method:
    • Wipe a needle or straight pin with rubbing alcohol.
    • Gently puncture the edge of the blister.
    • Press the fluid in the blister toward the hole so it can drain out.
  • Do not drain a blister of any size if:
    • You have a condition such as diabetes, HIV, cancer, or heart disease, because of the risk of infection.
    • You think your blister is from a contagious disease, such as chickenpox, because the virus can be spread to another person.
  • If a blister has torn open, or after you have drained a blister:
    • 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.

Home remedies may relieve itching from blisters. One way to help decrease itching is to keep the itchy area cool and wet. Apply a cloth that has been soaked in ice water, or get in a cool tub or shower.

Medicine you can buy without a prescription
Try a nonprescription medicine to help treat your fever or pain:

Talk to your child's doctor before switching back and forth between doses of acetaminophen and ibuprofen. When you switch between two medicines, there is a chance your child will get too much medicine.

Safety tips
Be sure to follow these safety tips when you use a nonprescription medicine:
  • Carefully read and follow all directions on the medicine bottle and box.
  • Do not take more than the recommended dose.
  • Do not take a medicine if you have had an allergic reaction to it in the past.
  • If you have been told to avoid a medicine, call your doctor before you take it.
  • If you are or could be pregnant, do not take any medicine other than acetaminophen unless your doctor has told you to.
  • Do not give aspirin to anyone younger than age 20 unless your doctor tells you to.
