Alcohol allergy has caused dermatitis, presenting an allergic reaction with symptoms such as rash, generalized itching, and dizziness. Oral administration of loratadine or levocetirizine tablets can be used for anti-allergy treatment. If the rash is severe and covers a large area, an external application of calamine lotion can be used, which has anti-allergic and astringent effects. If oral medication is less effective, intravenous administration of calcium gluconate and high doses of vitamin C can be considered, along with the addition of dexamethasone for anti-allergy treatment, which generally provides relief. At the same time, it is necessary to avoid alcohol and try to eliminate it from the body, which can be facilitated by inducing vomiting or using laxatives to prevent reabsorption that could worsen the dermatitis or cause chronic issues. (Medication should be used under the guidance of a physician.)
