Itching of the skin occurs in the elderly. First, a mild, non-irritating emollient or moisturizer needs to be applied, such as applying vitamin E ointment or choosing dimethicone oil for circumferential application, especially after bathing, due to hot water rinsing the skin, causing localized skin dryness caused by water loss. Secondly, oral administration of levocetirizine hydrochloride oral solution or olopatadine hydrochloride tablets is needed to strengthen the anti-allergic and anti-itching effect. If the itching is still not well relieved, oral moistening and antipruritic capsules are needed for the therapeutic purpose of nourishing blood and moistening dryness, sparing wind and relieving itching. During the treatment period, you should avoid repeated scrubbing of the affected area with salt water, alcohol, vinegar essence, and avoid eating spicy and stimulating food.
