1. What is acute urticaria?

Acute urticaria or hives is a common skin disease in clinics. It is a local edema reaction caused by temporary inflammatory hyperemia and massive fluid exudation in the skin and mucosal vessels caused by various factors.

It is characterized by itchy skin and mostly after local scratching, wheals appear with different sizes and shapes -- or an edematous dome bulge, or patches of redness and can be common in childhood.

2. What causes acute urticaria?

Food allergies (fish, eggs, shrimp, etc.);

Drugs allergies (penicillin, vaccine, etc.);

Infections (viruses, bacteria, etc.);

Animal and plant factors (pollen, animal fur, etc.);

Physical factors (heat, cold, sunlight, etc.);

Genetic factors or mental factors.

3. What do you do if your child has acute urticaria?

(1). Elimination of pathogens:

Conditions caused by infection should be given effective anti-infective treatment; allergens should be avoided for conditions caused by allergies.

(2). Taking antihistamines:

Second-generation non-sedative antihistamines are preferred, such as cetirizine, loratadine and desloratadine.

(3). Glucocorticoids:

Prednisone, dexamethasone, or methylprednisolone may be used for severe urticaria or urticaria with laryngeal edema.

4. How do you prevent and treat acute urticaria in life?

(1). Be careful to observe and avoid suspected allergic triggers. If you find you or your child is allergic to a certain food or drug, you should stop consuming or using it immediately; avoid contact with suspected allergens as much as possible.

If you do not know which allergens you or your children have, you can go to the hospital outpatient clinic to take skin allergen detection a week after suspending taking suspect drugs.

(2). Cut your nails short. Do not scratch hard, otherwise the skin may become lacerated, resulting in a significant increase in the rash and itching.

(3). Avoid adverse stimulation. Hot compress should not be applied, otherwise it will stimulate and aggravate the itching.

(4). Keep the room clean and dry.

(5). Dietary attention should be paid to eating less spicy and stimulating foods.

(6). Rest more, avoid fatigue, and avoid excessive exercise.

(7). Maintain a healthy mind.
