Dyshidrotic Eczema


Dyshidrotic eczema is a recurrent skin rash with small fluid-filled blisters. The blisters appear on palms of your hands, on the sides of your fingers, and soles of your feet. The exact cause is unknown. Your risk may be increased if you have allergies, you smoke, or have other skin conditions, such as atopic dermatitis. Your risk may also increase if you eat a diet high in metal salts. Foods such as mushrooms, chocolate and coffee contain metal salts.


Contact your healthcare provider if:

  • The area of your rash is swollen, painful, draining fluid, and feels hot.
  • The blisters have yellow crust on them.
  • You have questions or concerns about your condition or care.


  • Medicines help decrease itching and how long you have a rash. This medicine may be a pill or cream. You may also need medicine to treat an infection.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him of her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Care for your rash:

  • Do not scratch your rash. Bacteria from your fingernails may enter your open sores during scratching and cause an infection.
  • Use moisturizes or emollients, such as petroleum jelly. These help relieve itching and help prevent bacteria from getting in your sores. If you have a doctor's order for medicated cream, apply that first. Then apply the moisturizer or emollient on top.
  • Wear cotton socks and gloves. Cotton keeps your rash dry, which helps with itching. Gloves and socks help your medicated cream work better.
  • Ask your healthcare provider how often you should wash your hands. You may need to wash them less often while they heal. Do not use hand sanitizer with ethyl alcohol.
  • Ask your healthcare provider if you need allergy testing. Allergy testing may help identify what triggers your eczema.

Prevent the return of your rash:

  • Identify and avoid possible triggers.
  • Avoid sweating more than normal.
  • Find ways to handle stress.
  • Decrease the amount of metal salts in your diet. Avoid onions, tomatoes, beans and beer. Ask your healthcare provider what other foods you should avoid.
  • Do not smoke. If you smoke, it is never too late to quit. Ask for information if you need help quitting.
