Herpetic Whitlow: Care Instructions

Overview

Herpetic whitlow is a finger infection. It's usually caused by the herpes virus that causes cold sores. It can spread to a finger from a cold sore in or around your mouth. Whitlow also can be caused by the virus that causes genital herpes.

An area of your finger may be red and swollen. It may have a small group of blisters. They are clear at first, then turn yellow. Over a few weeks, the blisters break open, crust over, and then heal. Your finger also may hurt, itch, or tingle.

Your finger should get better on its own. But whitlow may come back to the same area of your finger.

Your doctor may prescribe medicines to help fight the herpes virus. Covering your finger with a bandage can help to avoid spreading the infection.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and contact your doctor 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.

• Be safe with medicines. Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine.
• Ask your doctor if you can take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve).
• Follow your doctor's advice to care for your finger. If you did not get instructions:
  • Wash the area with clean water 2 times a day. Don't use hydrogen peroxide or alcohol. They can slow healing.
  • You may cover the area with a thin layer of petroleum jelly, such as Vaseline, and a nonstick bandage.
  • Wet a cloth with cool water and apply it to the finger. This can help with pain and itching.

When should you call for help?

Contact your doctor now or seek immediate medical care if:

• You have symptoms that the infection is getting worse, such as:
  • Increased pain, swelling, warmth, or redness.
  • Red streaks leading from the area.
  • Pus draining from the area.
  • A fever.

Watch closely for changes in your health, and be sure to contact your doctor if:

• You do not get better as expected.
