Frostbite: Care Instructions


Frostbite is freezing of the skin and tissues below the skin. It occurs when someone is exposed to freezing temperatures for too long. Frostbite most often happens to exposed parts of the body, like the fingers, toes, ears, and nose. Frostbite is described by degree, from first degree through fourth degree, based on the level of injury.

Treatment for frostbite includes relieving pain and quickly rewarming the frostbitten body parts (if there is no risk of the body parts freezing again). This can help prevent problems such as infection, dead tissue, or even amputation of the frozen part.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • If your doctor prescribed antibiotics, take them as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
  • Take pain medicines exactly as directed.
    • If the doctor gave you a prescription medicine for pain, take it as prescribed.
    • If you are not taking a prescription pain medicine, take an over-the-counter medicine, such as ibuprofen (Advil, Motrin) or naproxen (Aleve), to reduce pain and swelling. Read and follow all instructions on the label.
    • Do not take two or more pain medicines at the same time unless the doctor told you to.
  • Protect skin that has been injured by frostbite.
    • Do not expose frostbitten skin to cold temperatures.
    • Sunscreen and protective clothing can protect frostbitten skin from damage by the sun.
    • Do not rub or massage the injured area.
  • Do not disturb blisters or other sores.
  • Apply aloe vera to your skin as directed by your doctor.
  • Do not smoke. Smoking can interfere with healing. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
  • Avoid alcohol. It can slow recovery.

When should you call for help?

Call your doctor or nurse advice line now or seek immediate medical care if:

    • Red streaks leading from the wound.
    • Pus draining from the wound.
