condition, another systemic disease like cancer, or unknown.
* Chronic inducible urticaria is caused by certain environmental and physical factors.
Identifying urticaria triggers
Common triggers include:
* Allergens, including certain foods
* Exposure to heat/cold
* Tight clothing
* Insect stings and bites
* Infections and viruses
* Medications such as antibiotics and NSAIDs
* Diseases including asthma, celiac disease, diabetes, lupus, rheumatoid arthritis, thyroid disease, vasculitis and vitiligo
* Stress
Diagnosis and treatment
The cause of your chronic urticaria may be hard to identify. It's best to see a specialist such as a board-certified allergist or dermatologist for diagnosis and treatment.
Your doctor may perform allergy tests, lab tests or a skin biopsy to rule out other
conditions that involve or resemble
hives. You can help by keeping a diary that tracks your symptoms.
Chronic urticaria eventually goes away by itself. Management focuses on the most appropriate treatment to control symptoms, usually starting with the first line of treatment: a long-lasting antihistamine.
Antihistamines block production of histamine to reduce or eliminate hives and ease itch and swelling. Ask your doctor for a non-sedating antihistamine.
Topical itch creams may provide mild relief for hives that do not cover the entire body.
Corticosteroids: Topical corticosteroids reduce inflammation, irritation and itching. By reducing inflammation, they also promote healing. For a severe hives flare-up, a short course of oral corticosteroids (prednisone) can help reduce inflammation and itching. These medications can cause serious side effects, especially if taken long-term. It's important to follow your doctor's instructions when taking oral corticosteroids.
Advanced treatments
It's important to work closely with your doctor if your hives don't respond to treatment. If antihistamines alone do not help, your doctor may recommend combining them with other medications, including leukotriene modifiers or H2 blockers. New advanced treatments are available, and more are in clinical trials or undergoing FDA review.
Biologics: Omalizumab is a biologic medication used to treat chronic urticaria when antihistamines haven't worked. Two more biologics are in development as chronic urticaria treatments: dupilumab is in FDA review and briquilimab is in clinical trials. Biologics work by targeting cells and interrupting the inflammatory process. This stops or reduces symptoms
