Artificial urticaria is a disease caused by allergies, and it is one of the more difficult types of urticaria to treat. This disease is not contagious and will not spread through contact with others. Once diagnosed with this disease, formal treatment is necessary, and one can visit the dermatology department of a standard hospital for oral antiallergic medication treatment. If the condition persists for a long time and the treatment effects are unsatisfactory, it might be helpful to check for allergens to ascertain what triggers the allergy. Common allergens often include diet, living environment, dust mites, or pollen. Therefore, during and after treatment, it is advisable to enhance physical exercise to boost immunity, avoid keeping pets, stay away from places with dense vegetation, and refrain from consuming spicy and stimulating foods.

Characteristics of papular urticaria

Papular urticaria is a type of allergic reaction, generally associated with contact with irritants, or bites from mosquitoes and fleas. The likelihood of occurrence increases if small animals are kept at home. Typically, small red papules or red wheals appear on localized areas of the body or extensively, with a transparent blister on top. The itching is quite severe, and the blisters are prone to bursting when scratched. Once symptoms appear, it is crucial to treat them with proper medication, and care should be taken to prevent infection if the blisters are scratched open. To prevent recurrence, it is advisable not to keep small animals at home, to frequently disinfect clothes, sheets, and duvet covers by exposing them to sunlight to eliminate mites or fleas, and to maintain a standard diet and lifestyle habits.

How to treat chronic urticaria?

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.

Is postpartum urticaria contagious?

Postpartum urticaria is not contagious. The occurrence of urticaria is mainly an allergic reaction to various factors such as certain foods, medications, plants, or infections. Clinically, it mainly manifests as dilation and increased permeability of small blood vessels in the skin and mucosa, resulting in skin rashes and redness. However, this condition is related to a decrease in the body's immune strength, making postpartum urticaria more likely to occur after childbirth. Postpartum urticaria has a certain hereditary nature. When postpartum urticaria occurs, one should not scratch it to prevent breaking the skin and causing secondary infections. Avoid using irritating liquids for cleansing or hot water for washing. When itching occurs, topical antipruritic agents can be applied. It is advisable to eat fresh vegetables and fruits in daily life and avoid spicy and irritating foods.
