Overview

Chronic hives are long-lasting raised, red, and itchy patches of skin. Hives usually have red borders and pale centres. They range in size from ½ centimetre to 8 centimetres (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 your child may have swelling without hives. Swelling may hurt a bit, but it does not usually itch like hives.

Your child cannot spread hives to other people.

How can you care for your child at home?

• Avoid whatever you think may have caused your child's 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.
• Ask the doctor about giving your child a non-drowsy antihistamine, such as loratadine (Claritin), to reduce itching. 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 your child has a severe reaction. Learn how to give your child the shot, and keep it with you at all times. Make sure it has not expired. If your child is old enough, teach your child how to give the shot.
• If your doctor prescribes another medicine, give it to your child exactly as directed.
