Most patients with alcohol allergy recover slowly on their own, mainly because of individual differences, so they react to the concentration of alcohol in some way. Some people may show only localized contact site erythema, or irritating itching symptoms. Some people may develop systemic symptoms due to irritation after drinking alcohol, such as generalized erythema and congestion, and some may even have certain systemic manifestations, such as dizziness. Alcohol allergy may also injure the internal system, and some people may suffer from liver damage due to alcohol allergy and poisoning. If a patient has alcohol allergy symptoms, he or she should try to avoid contact with alcohol or drinking alcohol, and should also apply topical glycolic lotion to stop itching.
