The primary cause of sudden alcohol intolerance is often a deficiency or inactivity of an enzyme called aldehyde dehydrogenase 2 (ALDH2). This enzyme helps metabolize acetaldehyde, a toxic byproduct of alcohol consumption. These symptoms can occur immediately after alcohol consumption and are often a result of high histamine levels in certain alcoholic drinks like red wine. Alcohol intolerance is a condition where the body is unable to break down alcohol properly, leading to uncomfortable symptoms such as flushing, headaches, and nausea. It’s important to note that even if you don’t have a true allergy to alcohol, it’s still possible for it to trigger other allergies such as hay fever. If you experience unusual symptoms after drinking alcohol, seek medical attention right away.
Medical Conditions and Alcohol Intolerance
- Cleveland Clinic’s health articles are based on evidence-backed information and review by medical professionals to ensure accuracy, reliability, and up-to-date clinical standards.
- Over a decade later, research is still being conducted into alcohol intolerance.
- No, alcohol intolerance cannot be cured, especially when genetic factors like ALDH2 enzyme deficiency cause it.
- Keep a detailed journal to track which types of alcohol (e.g., wine, beer, or spirits) and quantities trigger your symptoms.
- Blood pressure medications, antidepressants, and pain relievers might also increase sensitivity.
- Alcohol, particularly certain alcoholic beverages like wine and beer, can trigger the release of histamine.
The accumulation of acetaldehyde, a toxic byproduct of alcohol metabolism, plays a key role in many of these symptoms. More commonly, people develop allergies or intolerances to common ingredients in alcoholic drinks, such as grains, preservatives, or sulfites. Alcohol intolerance can also develop or worsen over time because of changes in enzyme production or liver function.
Diagnosis and Testing for Alcohol Intolerance
Alcohol intolerance is Alcohol Intolerance still normally uncommon in people with these types of conditions. The antibiotic metronidazole (Flagyl) can cause alcohol intolerance while being used. Another medicine called disulfiram (Antabuse) is actually designed to cause alcohol intolerance to help people stop drinking.

- You may be allergic to one of the substances in alcohol (a chemical, grain or preservative, such as sulfite).
- Unlike alcohol intolerance, an allergy can be dangerous, so medical advice is essential.
- If you have histamine intolerance, you lack a digestive enzyme called diamine oxidase, which helps your body break down excess histamine.
People of East Asian descent are more likely to inherit the genetic mutation causing alcohol intolerance, leading to a higher prevalence of the condition in this population group. Alcohol intolerance is a topic that often goes undiscussed but is crucial to understand, given its effect on the health and well-being of those affected. This section aims to shed light on the definition, causes, symptoms, and effects of alcohol intolerance.
ADH Enzyme Variants
For instance, wines and beers often contain sulfites, preservatives that can trigger allergy-like symptoms. Some people might find their nose blocked or running after drinking alcohol. This is because alcohol can cause the blood vessels inside the nose to swell, producing more mucus and causing symptoms similar to a cold or allergic rhinitis. Facial flushing can be an uncomfortable and embarrassing reaction to alcohol, but it’s also a helpful indicator of alcohol intolerance.
