Urticaria, or hives, is a very common skin rash
that can be caused by many things. One out of every five people will get
hives sometime in their lifetime.
What causes
urticaria, or hives?
Sometimes it is caused by a drug, such as aspirin
or an antibiotic, but it can be caused by foods, especially eggs, seafood,
chocolate, or nuts or by heat, exercise, stress, or, rarely, sunlight.
A specific cause for hives is found in less than
one half of all cases. In some people, stress may cause hives. If your
hives last for more than 6 weeks, your physician may look for other causes
of your hives.
Is there anything I can do to keep it from breaking
out?
You should avoid things that you think may be
causing you to break out, such as a medicine of food. Ask your physician,
if you are unsure.
Even though you may not come in contact again
with whatever caused your hives, the hives may last for 2 to 4 weeks. You
should follow your physician's advise carefully.
How can I tell what is causing the hives?
Make a list daily of everything you eat and drink
and any medicines you take or use, including creams, lotions, eye drops,
perfumes, sprays, soaps, etc., and try to see if there is any pattern to
what you are being exposed to and when you get hives.
Is there any medicine I can get to help with the itching?
Antihistamines (i.e., Benadryl) are used to treat
urticaria or hives. You must know and follow exactly how your physician
wants you to take the medicine. Let your physician know if your medicine
is not working. Sometimes several medicines must be tried before the best
one is found.
Some antihistamines may make you sleepy, so be
very careful with driving or other such activities if you take one of these.
Several newer antihistamines are now available
that do not cause drowsiness.
