Your Care Instructions

Chronic hives are long-lasting raised, red, and itchy patches of skin called wheals or welts. This condition is also called chronic urticaria. Hives usually have red borders and pale centres. They range in size from ½ centimetre to 7 centimetres 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. A single spot of hives may last less than 36 hours, but the problem may come and go for weeks or months. In most children, the problem often lasts less than 1 year and almost always goes away within 5 years.

Hives may occur with swelling under the skin (called angioedema). But your child may have swelling without hives. Swelling may hurt a bit, but it does not usually itch like hives. It can be dangerous if severe swelling affects your child's throat, but this is very rare.

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.
