Skin allergies on the back of the hand can be relieved by general treatment and medication, but the specific efficacy varies from person to person and there is no such thing as the fastest way. 1. General treatment: First of all, we should actively search for the cause of the disease and keep away from possible allergens. After cure, avoid contact with possible allergens to prevent recurrence. 2. Medication: Topical glucocorticosteroid medication such as glycerite lotion or dianabed cream, mometasone furoate ointment can be used topically to treat the condition. Severe itching can be applied to loratadine, benadryl and other drugs. If the patient’s symptoms are very serious, glucocorticoid drugs such as prednisone can also be used systematically as appropriate. The use of specific drugs should be under the guidance of a doctor. If there is any discomfort, it is recommended to consult a doctor in time for diagnosis and treatment.
