Eczema on the hand is related to long-term contact with water or detergent. The medicine can be mometasone furoate ointment, desonide ointment or zinc borate borneol ointment, and the oral medicine can be loratadine tablets or levocetirizine tablets. It is suggested to take compound glycyrrhizin capsules orally, which will have better therapeutic effect. Usually reduce the frequency of hand washing, avoid contact with chemicals such as soap and detergent, apply moisturizer or hand cream in time after hand washing to form a skin barrier to prevent eczema from recurring, and wear isolation gloves when washing dishes or washing clothes.
