Sunburn can occur when the neck is red from the sun, mainly as a well-defined, edematous erythema. In severe cases, blisters and papules may appear on top of the erythema, and may break down due to scratching. Clinical treatment requires oral loratadine capsules once a day, one capsule once a day, combined with compound glycopyrrolate capsules three times a day, two capsules once a day. If the edema is more obvious, accompanied by pain, you can change the oral compound glycyrrhetinic acid capsule to static compound glycyrrhetinic acid injection 0.12 grams once a day, or even intramuscular injection compound betamethasone injection temporary once, once a glucocorticoid to enhance the therapeutic effect. At the same time in the affected area can be wet compress 0.9% saline twice a day, once for 20 minutes.
