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.
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 or nurse call line 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.
