Hives
Are Hives making your life miserable? The doctors at Miramar Dermatology can help.

10-20 percent of the population of the United States suffers from hives or “wheals” in one form or another. The symptoms of hives include redness, swelling, burning, stinging and itchiness. While some hives are impossible to treat, the doctors at Miramar Dermatology have a battery of tests and treatments that work well for the majority of people.

Where do hives come from?

Allergies to food or medication can cause the release of a chemical called Histamine. Hives are formed when Histamine leaks from cells along the path of the blood vessels called “Mast Cells”. The severity of hives depends on the cause and the time it takes for symptoms to dissipate. Acute Urticaria is the medical term for hives that last less than six weeks. Causes for Acute Urticaria are usually identifiable and the most common causes include food, drugs, infections and insect bites. Acute Urticaria can also be caused by cold, sunlight and pressure.

The most common food causes of hives are nuts, chocolate, fish, tomatoes, eggs, fresh berries, and milk. Fresh or raw foods cause hives more often than cooked foods. Food additives and preservatives may also cause hives. Hives caused by food allergies usually appear within minutes, although sometimes it can take up to two hours after eating. Almost any prescription medication can cause hives and it is very important to contact your doctor if you have a physical reaction after taking a drug.

What Can I do?

The best treatment for hives is to find and remove the cause. Antihistamines prescribed by your dermatologist oftentimes provide relief. Antihistamines work best if taken on a regular schedule to prevent hives from forming. Unfortunately, it may take time to find the antihistamine that works with your particular body chemistry and the doctor may have to try different medications. In severe hives, an injection of epinephrine (adrenalin) or a cortisone medication may be needed.
