Allergic urticaria is a kind of hypersensitivity reaction, which is caused by the exposure to certain allergens. It is characterized by the formation of hives, which are red, itchy and swollen patches on the skin that appear suddenly.

The most common allergens that can trigger allergic urticaria are certain foods, medicines and insect bites. When someone comes into contact with one of these triggers, their immune system reacts by releasing histamine and other chemicals into the blood, which causes the hives to develop.

It is important to know the triggers of allergic urticaria in order to avoid them. If someone is aware of the foods, medications or insect bites that cause an allergic reaction, they should avoid them. For those who are unaware of their triggers, an allergist can help to identify them.

Treatment for allergic urticaria usually involves medications such as antihistamines, corticosteroids and omalizumab. These medications can help to reduce the itching, swelling and hives associated with the condition. In some cases, it may also be necessary to take additional medication to reduce the risk of an allergic reaction.

By avoiding the triggers of allergic urticaria and taking the necessary medications, it is possible to reduce the symptoms and ensure a better quality of life.
