Alcohol intolerance can cause immediate, unpleasant reactions after you drink alcohol. The most common signs and symptoms of alcohol intolerance are stuffy nose and skin flushing.
The only way to avoid alcohol intolerance symptoms or an allergic reaction is to avoid alcohol or the particular beverage or ingredients that cause the problem. For a minor reaction, over-the-counter or prescription antihistamines may help reduce symptoms, such as itching or hives. However, antihistamines can't treat a serious allergic reaction.
Despite the widespread assumption that drinking alcohol is an integral part of growing up, a 2012 report into why young people abstain showed that choosing not to drink is commonplace, Figures show that around half of 16 to 24 year olds in England said they'd drank nothing the week before they were asked about their drinking habits.
