Hives (Urticaria)
Hives, also known as urticaria, cause itchy welts on the skin that “come and go”.
These welts can vary in size, but each individual welt tends to last for less than 24 hours, and new lesions can form for weeks. In some patients, hives may be accompanied by swelling of certain body parts, like the lips, in a condition called angioedema.
At Virginia Square Dermatology, we will help you determine the cause and best treatment for your urticaria.
What causes hives?
There are two main types of hives:
Acute urticaria: hives lasting fewer than 6 weeks. Acute urticaria is most commonly triggered by medications, infections, and certain foods.
Chronic urticaria: hives lasting longer than 6 weeks. Chronic urticaria can have multiple causes, including genetics, certain medical conditions, and medications.
What is the treatment for hives?
First, if you have hives along with lip or throat swelling, itchy throat, or difficulty breathing, we recommend going to the emergency room or calling 911.
The main treatment for urticaria is the use of non-sedating and sedating oral antihistamines. Sometimes, hives are also treated with corticosteroids, omalizumab, or montelukast.
