What are Urticaria?
Urticaria, or hives, are raised, itchy plaques on the skin that can occur out of nowhere or from an easily identifiable cause. When there is associated swelling in the area around the hives this is called ‘angioedema.’
Examples of urticaria triggers include:
Allergies, to things like medicine, foods or plants
Infections of any kind
Changes in body temperature
Exposure to temperature extremes such as a hot shower
Hives are classified as acute or short-term when they last less than 6 weeks and chronic or long-term when they last for more than 6 weeks. When hives last for more than 6 weeks, they can be a sign of a more chronic illness.

Urticaria Diagnosis and Treatment
Diagnosis is made by reviewing medical history and a physical exam with special focus on figuring out the trigger, especially if the trigger is an allergy.
Since they are caused by a release of histamine, hives can be treated with antihistamines such as benadryl (diphenhydramine), claritin (loratadine), or zyrtec (cetirizine).
Do Hives Mean My Child Has an Allergy?
Not necessarily and, actually, not usually. Most hives in children occur because of infections which children are fighting all of the time.
However, if hives occur near the time of exposure to a certain food or medicine, then an allergy should be suspected. In this case, watch closely for the following symptoms:
Throat tightening
Difficulty breathing
Stomach cramping
Vomiting and/or diarrhea
Passing out
These can be symptoms of a serious allergic reaction, or anaphylaxis, and you should take your child to the emergency room immediately. After treatment, they will need to see an allergist.
See a Doctor in Person If…

If the urticaria last more than 6 weeks
If your child experiences weight loss or night sweats
