Your Care Instructions

Hives are raised, red, itchy patches of skin. They are also called wheals or welts. They usually have red borders and pale centres. Hives 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 form a large area of raised, red skin.

You can get hives after an insect sting, after taking medicine or eating certain foods, or because of infection or stress. Other causes include plants, things you breathe in, makeup, heat, cold, sunlight, and latex.

You cannot spread hives to other people. Hives may last a few minutes or a few days, but a single spot may last less than 36 hours.

How can you care for yourself at home?

• Avoid whatever you think may have caused your hives, such as a certain food or medicine. However, you may not know the cause.
• Put a cool, wet towel on the area to relieve itching.
• Take an over-the-counter antihistamine, such as diphenhydramine (Benadryl), cetirizine (Reactine), or loratadine (Claritin), to help stop the hives and calm the itching. Read and follow directions on the label. These medicines can make you feel sleepy. Do not drive while using them.
• Stay away from strong soaps, detergents, and chemicals. These can make itching worse.
