Chronic allergic urticaria is a common skin condition characterized by red or skin-colored welts on the skin, accompanied by intense itching. These symptoms may last for weeks to months.

Avoiding the allergen is the first step in treating chronic allergic urticaria. Patients should actively identify and avoid contact with known allergens, such as seafood, airborne pollen, and dust mites. After removing the allergen, symptoms usually improve in most patients.

Medication is essential and includes antihistamines to relieve symptoms such as itching and redness. In some cases, doctors may prescribe corticosteroids or immunosuppressants, especially when conventional antihistamines fail to control symptoms. For patients with severe symptoms, topical corticosteroids such as hydrocortisone cream or halometasone cream may be used under a physician's guidance to rapidly reduce inflammation and itching.

For chronic urticaria caused by known allergens, desensitization therapy can be a beneficial treatment option. This therapy involves gradually increasing exposure to the allergen under a doctor's supervision, training the body to tolerate the specific allergen over time.

If symptoms occur, it is recommended to seek timely medical consultation at a hospital, and follow the doctor's instructions for treatment after a clear diagnosis to avoid delaying the condition.
