The root cause of recurrent skin allergies is allergen avoidance. If allergen avoidance is not effective, or if allergen avoidance is not possible, medication is needed.
The essence of allergy lies in the abnormality of the immune system, and there is no cure for it except avoidance measures. There are a few allergens, such as pollen and dust mites, that cannot be avoided completely, but desensitization can be used, but this method is only effective in some people and generally takes several years of continuous treatment to be effective.
The main treatment drugs are histamine antagonists, such as chlorpheniramine maleate, loratadine, cetirizine, etc., which can inhibit the allergic symptoms after oral intake, but it is difficult to eradicate. For patients with persistent and severe allergies, consider combined treatment with cimetidine and ketotifen.
Chronic allergy and the cause of allergy is clear can always have anti-allergy drugs to prevent and control themselves. The first occurrence of allergy is recommended to go to the hospital as soon as possible to do regular treatment, otherwise delayed allergic diseases are easy to chronic, leading to future treatment difficulties. The above medications should be used in accordance with medical advice.
