In the case of alcohol allergy, the first step is to stay away from the allergen and avoid continued or re-exposure to alcohol. If the symptoms are mild, with mild local itching and swelling of the skin, without rash, breathing difficulties or other uncomfortable symptoms, special treatment is usually not necessary. However, if the skin itching continues to worsen, or other uncomfortable symptoms appear, you need to seek medical attention. If the discomfort is more obvious, such as more local skin rash, accompanied by redness, swelling and pain, you can follow medical advice to use chlorpheniramine maleate tablets, benadryl and other drugs for treatment. If the allergy is more serious, with generalized itching of the skin, or even headache, difficulty in breathing, etc., you need to seek medical treatment in time to avoid serious consequences. Clinical treatment usually starts with decongestion, which can be done with high concentrations of glucocorticoids or diuretic drugs to reduce edema and antihistamines such as loratadine to control allergic manifestations. If symptoms of airway obstruction occur, tracheal intubation is also required to help keep the patient breathing. In addition, people with alcohol allergy need to take active precautions in their daily lives to avoid exposure to or consumption of alcohol products. If alcohol intolerance is due to disease, most patients can regain tolerance to alcohol after treatment of the original disease. Alcohol consumption should be prohibited after taking medication in daily life to avoid adverse reactions.
