The enzyme responsible for breaking down alcohol, called alcohol dehydrogenase, is less efficient in these individuals. As a result, acetaldehyde, a byproduct of alcohol metabolism, builds up in the body and triggers the skin reaction. While the Alcohol Flush Reaction is a clear visual indicator of alcohol intolerance, it’s important to remember that it’s not the only sign. Other symptoms such as rapid heartbeat, headache, and nausea should not be ignored.
Are there any non-alcoholic beverages that can cause similar allergic reactions?
People who have a true alcohol allergy should avoid drinking alcohol entirely. Alcohol intolerance is typically diagnosed through a combination of self-observed symptom tracking, a detailed medical history and a physical exam. A healthcare provider will ask about your symptoms, their frequency and duration, and what types of alcohol seem to trigger them. This genetic trait is particularly common among individuals of Asian descent, where a significant percentage possess this deficiency.

Anaphylaxis is a severe and life-threatening allergic reaction that can cause dangerously low blood pressure and problems breathing. If you have a severe reaction and carry an EpiPen (epinephrine), use it and call 911. Your immune system may experience changes as you age, as well as the way your body metabolizes substances. Changes in diet or a health condition may also contribute to suddenly developing an allergy to alcohol. It is estimated that as many as 50 million Americans may suffer from some type of allergy. If you or a loved one are dealing with allergy symptoms, see your Baptist Health physician for consultation and treatment.

A person experiencing a severe allergic reaction should go to the emergency room immediately. If the allergic reaction is more severe, people may require epinephrine, also known as an EpiPen. A person with severe allergies should carry one with them at all times, in case of a serious allergic reaction. There are several ways for a doctor to diagnose an alcohol allergy or intolerance, including the approaches below.
True alcohol allergy (versus an allergic reaction to ingredients in alcoholic drinks) is very rare. In some cases, individuals with known allergies to substances other than alcohol may experience cross-reactivity when consuming alcoholic beverages. Cross-reactivity occurs when the immune system recognizes similar proteins in different substances, leading to an allergic reaction. For example, individuals with a known allergy to birch pollen may experience a cross-reaction when consuming certain alcoholic beverages, such as beer or wine. Alcohol consumption can sometimes lead to unwanted skin reactions, including alcohol allergy rash. Understanding this condition and its symptoms is essential for those who experience such reactions or want to learn more about it.
Allergy Treatment
Symptoms of a genuine alcohol allergy are typically severe and can include hives, significant swelling of the face, mouth, or throat, difficulty breathing, and anaphylaxis. Genetic predisposition plays a crucial role in the development of alcohol allergies. A notable example is the deficiency of the enzyme ALDH2, which is important for effectively breaking down alcohol in the body. This enzyme converts acetaldehyde, a byproduct of alcohol metabolism, into acetic acid. When the ALDH2 enzyme is deficient, individuals accumulate acetaldehyde, leading to symptoms of alcohol intolerance and potentially allergic reactions 2.
What Is an Alcohol Allergy?
The symptoms of alcohol intolerance can occur even with small amounts of alcohol. The symptoms may not be like typical drunkenness, including flushing and other effects. However, the inability to properly break down alcohol leads to higher blood alcohol levels, even after consuming Alcohol Intolerance small amounts. Alcohol intolerance may also cause you to drink less because of its unpleasant effects.
- While alcohol consumption doesn’t directly cause eczema, it can worsen existing symptoms and trigger flare-ups in some people.
- It occurs when the immune system mistakenly identifies certain components of alcohol as harmful substances.
- If the rash is severe or persists for more than a few days, it’s important to see a doctor.
- These reactions may range from mild discomfort to severe allergic responses.
- Alcohol allergy symptoms can range from mild, such as an itchy mouth or eyes, to severe, including vomiting or anaphylaxis.
Consult a doctor to evaluate for a potential alcohol allergy and receive proper treatment. The most effective way to prevent alcohol allergy rash is to avoid consuming alcohol altogether. This includes abstaining from any alcoholic beverages that may trigger an allergic reaction. By eliminating alcohol from your diet, you can significantly reduce the likelihood of experiencing a rash or other allergic symptoms. However, people with alcohol intolerance often have a genetic variant that causes ALDH to work less effectively. As a result, acetaldehyde builds up in their body, leading to uncomfortable symptoms.
