Recurrent episodes of urticaria are usually chronic urticaria. It is now believed that when chronic urticaria flares up, in addition to being related to an allergic reaction, it can usually be caused by an autoimmune abnormality. Therefore, it is important to look for allergens such as sunlight, alcohol or gasoline as soon as possible when chronic urticaria occurs, as these may be the allergens that cause recurrent urticaria, and to avoid contact with these allergens as much as possible. If chronic urticaria is still difficult to control after lifting the allergen, you can also choose to take more stable and regular anti-allergy medications, such as histamines. It is also important to note that if the hives are particularly severe, hormonal medications can be taken on a short-term, regular basis. At the same time, it must be noted that since all medications have certain side effects, especially histamines, there may be drowsiness or central disorder symptoms. Therefore, the medication must be taken under the guidance of a doctor and also according to the characteristics of the individual in order to avoid the side effects of the medication to the greatest extent possible. Having avoided the triggers, it also includes the need to control the diet and not to eat sour and spicy stimulating foods, while emotionally you must relax and not be overly tense, anxious and depressed, etc.
