Chronic urticaria often utilizes antihistamine medications to control symptoms, combined with Traditional Chinese Medicine (TCM) and differential diagnosis and treatment. Treating chronic urticaria generally requires long-term use of antihistamines, sometimes for two or three months, or even up to six months, a year, or more. Typically, treatment involves the combination of two or more types of antihistamines. For cases of chronic urticaria where antihistamines are ineffective, immunosuppressants may be used to adjust the body’s immune state, thus controlling the outbreaks of chronic urticaria. Chronic urticaria is a long-term, slow process that cannot be resolved quickly, so it is important to try to identify the triggering factors of chronic urticaria, or to identify specific allergens. However, finding the allergen is usually challenging because many patients with chronic urticaria have conditions that are also related to their own immune status.

What is the fastest way to relieve itching from hives?

Urticaria is a type of allergic disease that generally causes large areas of hives to appear rapidly all over the body, accompanied by severe itching. A quick method to relieve itching is the topical application of calamine lotion extensively and taking oral antihistamines, such as loratadine tablets. In cases of acute flare-ups, it may be appropriate to use hormone-based medications, such as dexamethasone injection, administered intravenously or through infusion, as these act quickly. For chronic urticaria treatment, it is generally advised against the use of hormones; standard oral antihistamines should suffice. Urticaria tends to recur; therefore, it's important to maintain a controlled diet and lifestyle habits. Foods and substances to avoid include chili peppers, mutton, seafood, and alcohol.

Is urticaria contagious?

Urticaria, commonly known as hives, is not contagious. It is a localized edema of the skin and mucous membranes due to temporarily increased vascular permeability. Its pathological causes are not related to infection, thus it is not contagious. The specific cause of urticaria often remains unclear for many patients. Some cases are due to certain foods, such as animal proteins, seafood, fungi, and some food additives like tartrazine, balsam of Peru, and sulfites. Some cases are triggered by drugs such as penicillin and various vaccines. Others are caused by allergens inhaled through the respiratory tract or by contact with the skin; common examples include pollen, animal dander, dust, fungal spores, and dust mites, as well as some volatile cosmetics. Contact with certain items, such as insect bites, venomous insects, certain plants like nettles, or animal fur such as wool, can also trigger urticaria. Some cases may be related to physical factors such as exposure to cold, heat, sunlight, or pressure, all of which can potentially lead to the development of urticaria.

How to Distinguish Between Papular Urticaria and Urticaria

Papular urticaria, also known as insect bite dermatitis, is a different disease from urticaria. Urticaria, also known as wheals, is called yinzhen in traditional Chinese medicine, and it is a localized edema of the skin and mucous membranes due to temporary increased vascular permeability. For most patients with urticaria, the exact cause cannot be identified. Common causes include foods, such as animal proteins and certain food additives that induce urticaria. Urticaria can also be triggered by certain infections as allergens, as well as by certain medications such as penicillin, serum products, various vaccines, sulfonamides, etc. Additionally, common inhalants such as pollen, animal dander, dust, fungal spores, dust mites, and volatile chemicals can also trigger urticaria. Papular urticaria is characterized by a small blister in the center of a reddish area, often resulting from bites or stings of various insects like mosquitoes, mites, bees, etc., or from irritation by toxic sap on the skin. Improvement can be seen once removed from the allergenic environment.
