Hives (also known as urticaria) can occur anywhere, and consist of itchy welts or bumps on the skin. They might be accompanied by local or generalized swelling (angioedema). They often come and go. Hives might worsen with overheating, stress, and dry skin.

Causes

Hives can be caused by many things, including drugs, food, animal dander, and insect bites. Hives can also occur following some infections (mycoplasma and certain viruses). Finding the cause often requires considerable "detective work" and patience. Detailed history, skin testing and environmental control are some of the tools used to identify the cause. This process can take several weeks.

Treatment

Treatment typically involves avoiding the causative agent, avoiding factors known to worsen hives, and regular suppressive therapy with an antihistamine. Use the Eczema guidelines for dry skin. Allergy shots may be offered in certain situations. Acute hives resolve in less than six weeks. Chronic hives often last at least one year.

Anaphylaxis

Rarely, an allergic reaction can progress beyond simple hives to involve the face, airway, or entire body. This can send the individual into shock and is a medical emergency known as anaphylaxis. If you have concerns that your child has severe allergies, please contact your physician or call the Allergy office to schedule a consultation.

Contact your physician immediately or call 911 if:

• Your child is having difficulty breathing.
• Your child has swelling involving the face or throat such that your child's airway could become blocked.

Contact your physician's office if:

• You are concerned about your child's allergies;
• Your child is avoiding certain foods for fear of allergies;
• You believe your child is developing asthma;
• There is a sudden change in your child's asthma or allergies;
• You have any other concerns or questions.
