What should I do if my hand is allergic?

If you experience an allergic reaction on your hands, you should immediately stop contact with the allergen, such as detergents, cosmetics, and other irritants, and avoid scratching the affected area to prevent infection. Depending on the severity of the allergic reaction, different measures can be taken: for mild redness and itching, calamine lotion can be used to provide a cooling and anti-itch effect; if symptoms are more severe with blistering and oozing, wet compresses should be applied initially, using normal saline or boric acid solution. After the skin lesions have dried, apply anti-allergic ointments such as corticosteroid creams. Additionally, oral antihistamines such as loratadine or cetirizine can be taken to relieve allergic symptoms. If symptoms persist or worsen, it is recommended to seek medical attention promptly and follow the doctor's instructions for treatment. Moreover, keeping the hands clean and dry and avoiding further contact with allergens are important measures for preventing hand allergies.
