If you suffer from chronic hives, we know how frustrating and debilitating the condition can be. Our dermatologists can help you find the right treatment for your individual case.


Hives, also known as urticaria, are itchy, red welts that can appear on any part of the body. Hives are often triggered by an allergic reaction, but they can also be caused by stress or other factors. Hives can last for a few hours or even up to several weeks.
Chronic hives are the term used to describe hives that last for more than six weeks. While hives can be a nuisance, they are generally not dangerous. However, in rare cases, hives can be a sign of a more serious condition, such as anaphylaxis.
If you have hives and are having difficulty breathing, seek medical attention immediately.

For most people, finding the exact cause of their hives is difficult, if not impossible. However, there are a few things that can be done to help narrow down the possibilities and find some relief. If you have hives, it is important to see a doctor so that any underlying medical conditions can be ruled out. Once a medical cause has been ruled out, we will work to identify the trigger of your hives.
There is no cure but there are treatments that can help to ease the symptoms.
- Antihistamines are often used to treat hives. Antihistamines can be taken orally or topically. But oral antihistamines can cause drowsiness, so they may not be suitable for everyone.
- Topical antihistamines are less likely to cause drowsiness but may not be as effective as oral antihistamines.
- If you have chronic hives, dermatologists may also prescribe a corticosteroid to help relieve the symptoms. Corticosteroids can be taken orally or injected.
- In some cases, immunotherapy may also be recommended. Immunotherapy is a long-term hives treatment that can help to prevent future flare-ups.

We work with you to narrow down possible causes, address any underlying conditions, and identify triggers to provide lasting relief from hives. If you keep a diary of your hives, we discuss them here.

We’ll review treatment options such as antihistamines, corticosteroids, trigger avoidance, and immunotherapy, while also providing prevention tips to help you work toward a symptom-free future.
What do hives look like?
Hives usually appear as red, raised, itchy welts on the skin. They may vary in size, sometimes look like blisters, and can occur anywhere on the body—including the face, lips, tongue, throat, hands, feet, or genitals. In some cases, the welts have a pale center. Hives may appear alone, in clusters, or spread across large areas.
Are hives always itchy?
Yes, itchiness is the most common symptom. The severity ranges from mild irritation to intense itching that disrupts sleep or daily activities. Scratching can worsen symptoms or cause infection. Relief may come from antihistamines, cool compresses, or prescription medication if over-the-counter options don’t work.
What are the different types of hives?
What causes hives?
Hives are often triggered by allergic reactions to foods (nuts, eggs, shellfish, milk, soy, wheat), medications (aspirin, ibuprofen, antibiotics), insect bites, or environmental allergens (pollen, dust, pet dander). Other causes include infections, autoimmune disorders, hormonal changes, emotional stress, or unknown factors. Sometimes no clear trigger can be identified.

Can hives be prevented?
Yes, in many cases. Keeping a symptom diary can help identify triggers. Avoiding problem foods, medications, or environmental allergens reduces outbreaks. Stress management, moisturizing, and avoiding tight clothing may also lower flare-ups. For chronic hives, regular care with a dermatologist or allergist is the best prevention strategy.

We will review your symptoms, medical history, and triggers, followed by a skin exam to confirm your diagnosis.

We don’t believe in one-size-fits-all care. Instead, we’ll create a personalized plan for your needs, goals, and lifestyle.

We’ll monitor your progress, adjust treatments as needed, and guide you in preventing flare-ups for long-term skin health.
