Hives

What are hives?

Hives, or urticaria, are a skin reaction where red itchy welts suddenly appear on your body. The welts can vary in size and shape, and they often go away as suddenly as they appeared. Hives can occur in nearly any location and may sometimes change from one spot to another.

Acute hives

Most cases of hives are acute, which means they go away within anywhere from a few hours to six weeks. The most common triggers for acute hives are allergic reactions, such as food allergies, insect allergies, and latex allergies. Other possible triggers for acute hives can include medication, heavy exercise, and heat. 

Chronic hives

Chronic hives are more serious because they last for more than six weeks, sometimes for more than a year. In most cases, chronic hives aren’t allergic reactions; however, the cause is often difficult to determine. 

Because hives can be a very complex condition, it’s important to work with the experienced team of specialists at Allergy, Asthma & Immunology Associates, LTD, to get to the bottom of your symptoms. With expert hives diagnosis and management, you can dramatically reduce outbreaks.

How do you treat hives?

Hives treatment depends on a few different individual factors, including the triggers and the severity of your symptoms. Your allergist helps you uncover hives triggers through careful questioning and allergy testing, such as patch testing. 

Avoiding your hives triggers is the cornerstone of hives treatment, but it’s not the only solution. Your allergist can prescribe antihistamines or steroids to ease severe hives symptoms, if necessary. 

If you have allergic hives, there are treatment options such as allergy shots and oral immunotherapy to desensitize you to your triggers. 

When are hives a medical emergency?

It’s rare for hives to be a medical emergency. In some cases, hives can be part of an anaphylactic reaction, which can potentially be deadly. 

When hives are part of anaphylaxis, they often accompany symptoms like breathing difficulties, tongue swelling, fainting, and wheezing. If you experience hives at the same time as possible anaphylaxis symptoms, it’s an emergency. Seek care immediately. 

If you have life-threatening allergies, your allergist may prescribe injectable epinephrine to keep with you for emergencies.
