Red spots on the face after drinking alcohol are more likely to be considered allergic dermatitis. The main reason is that after drinking alcohol, there is edema between and within the cells of the epidermis, dilatation of capillaries in the superficial dermis, and inflammatory exudation. In this case, oral loratadine capsules, which are not metabolized by the blood-brain barrier, can be taken once a day, and topical zinc oxide ointment of borate 1:1 mixed with black bean distillate can be applied twice a day. If the amount of alcohol consumed is relatively large, the patient can also be given a static dose of 5% glucose solution 500ml or 0.9% sodium chloride injection 500ml to rapidly metabolize the alcohol, which can play a role in the treatment of red dots and the effect of the patient is instructed not to use alcoholic beverages in the future.
