Chronic Hives: Care Instructions

Skip Navigation

Top of the page

Overview

Chronic hives are long-lasting raised, red, and itchy patches of skin. Hives usually have red borders and pale centers. They range in size from ¼ inch to 3 inches or more across. They may seem to move from place to place on the skin. Several hives may join to form a large area of raised, red skin.

When hives and swelling last more than 6 weeks even with treatment, they are called chronic.

Hives may occur with swelling under the skin. But you may have swelling without hives. Swelling may hurt a bit, but it does not usually itch like hives.

You cannot spread hives to other people.

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 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?

  • Avoid whatever you think may have caused your hives, such as a certain food or medicine. But you may not know the cause.
  • Put a cool, wet towel on the area to relieve itching.
  • Your doctor may suggest a nondrowsy antihistamine, such as loratadine (Claritin), to help control the hives. Be safe with medicines. Read and follow all instructions on the label.
  • Your doctor may prescribe a shot of epinephrine to carry with you in case you have a severe reaction. Learn how to give yourself the shot, and keep it with you at all times. Make sure it has not expired.
  • If your doctor prescribes another medicine, take it exactly as directed.

When should you call for help?

Give an epinephrine shot if:

  • You think you are having a severe allergic reaction.

After giving an epinephrine shot call 911, even if you feel better.

Call 911 if:

  • You have symptoms of a severe allergic reaction. These may include:
    • Sudden raised, red areas (hives) all over your body.
    • Swelling of the throat, mouth, lips, or tongue.
    • Trouble breathing.
    • Passing out (losing consciousness). Or you may feel very lightheaded or suddenly feel weak, confused, or restless.
    • Severe belly pain, nausea, vomiting, or diarrhea.
  • You have been given an epinephrine shot, even if you feel better.

Call your doctor now or seek immediate medical care if:

  • Your hives get worse.
  • You have mild belly pain or nausea.

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

  • You do not get better as expected.
