Heat-induced eczema can generally be treated with topical medications, oral medications, and daily protection. 1. Topical medication: If the local oozing is more, you can use saline, boric acid solution and other wet compresses, and when the oozing is reduced, you can use glycerine lotion; if there is no local oozing, you can choose corticosteroid creams, such as halometasone, fluticasone propionate cream and so on. 2. Oral medication: If the itching is too severe, oral anti-allergic drugs, such as cetirizine, loratadine, etc., can relieve itching symptoms. 3. Daily protection: keep the environment dry and hygienic, change clothes in time, bathe regularly, etc. If there are more outdoor activities, you should pay attention to daily sun protection and moisturizing. The above medications should be used under the guidance of a physician. If the symptoms are severe, please go to the hospital in time.
