It’s possible for adults to notice allergic reactions to alcoholic beverages, even if they’ve never had issues before. Though true alcohol allergies are rare, they still occur and can cause severe symptoms like rashes, trouble breathing, stomach cramps, collapse, or anaphylaxis.
Penn Medicine Becker ENT & Allergy’s nationally recognized allergy specialists bring deep expertise in identifying triggers and advising on care for late-onset reactions. Get in touch by visiting one of our more than 17 offices.
According to The American Academy of Allergy, Asthma & Immunology, True alcohol allergies are quite rare, under 1% of the global population.
Developing Late-Onset Alcohol Allergy
- You can develop an alcohol allergy in adulthood, even if you never had problems before.
- Ingredients in alcoholic beverages, such as sulfites, histamines, and specific grains, can trigger allergic reactions in sensitive individuals.
- Alcohol allergy often causes more severe symptoms than intolerance, such as skin rashes or breathing trouble.
- Age, genetics, and certain health conditions can raise the chance of developing a late-onset alcohol allergy.
- Proper medical evaluation, including allergy testing, is essential to confirm an alcohol allergy and differentiate it from other conditions.
What Is an Alcohol Allergy?
An alcohol allergy occurs when the immune system mistakenly identifies alcohol as a harmful substance, triggering an allergic reaction. This reaction involves the production of allergy-specific antibodies. Common allergens in alcoholic beverages that can cause such reactions are barley, hops, yeast, rye, wheat, gluten, and sulfites.
These allergens can be present in various types of alcohol, so it is essential for individuals with an alcohol allergy to carefully read beverage labels and understand the ingredients. Apart from the usual triggers, you might also be affected by other ingredients—like leftovers from the fermentation process, artificial fruit flavors, or even seafood proteins—that can set off allergic reactions. Keep an eye out for these possible culprits to reduce the risk of unwanted symptoms.
How is Alcohol Allergy Different from Alcohol Intolerance?
An allergy to alcohol occurs if your immune system responds negatively to alcohol, bringing signs such as hives, swelling, or difficulty with breathing. Alcohol intolerance, however, is present if your body has issues breaking down alcohol as it should. This is most often because of one’s genetics. It can cause unpleasant reactions, such as flushing or feeling sick.
Sometimes, what looks like intolerance might be a reaction to specific ingredients, such as chemicals, grains, or preservatives in the drink. Common signs of alcohol intolerance include flushed skin, hives, worsened asthma, stuffy nose, low blood pressure, nausea, vomiting, and diarrhea.

General Symptoms & Signs
The symptoms of an alcohol allergy can vary widely, ranging from mild intolerances to severe, dangerous allergic reactions. On the other hand, symptoms of alcohol intolerance, a more common condition, can be uncomfortable and sometimes severe.

Risk Factors for Developing an Allergy to Alcohol Later in Life
Certain factors can increase the risk of developing an allergy to alcohol later in life. These factors include age, genetic predisposition, pre-existing health conditions, and excessive alcohol consumption.
Individuals of Asian descent, those with asthma or hay fever, or those with allergies to grains or other foods are at higher risk for alcohol intolerance.
Age Group at Higher Risk
Although an alcohol allergy can start at any age, certain groups face a higher chance of developing one. If you’re a young adult who drinks heavily, watch for warning signs like facial redness, itchy skin bumps, or an upset stomach. Many people between 20 and 40 notice more alcohol-related issues because of heavier drinking patterns.
As you get older, you may suddenly find yourself more sensitive to alcohol if your body produces less of the enzyme that helps break it down. Researchers are still examining which ages are most vulnerable and why these allergies and intolerances happen.

Genetic Predisposition
Your genes can play a major role in whether you develop an alcohol allergy or intolerance. Many East Asians face a higher chance of alcohol intolerance because of reduced ALDH2 enzyme levels. According to a Cedars-Sinai piece by Nikolas Charles, around 30%-50% of this population experiences these reactions, often called “Asian flush” or “Asian glow.” This enzyme helps break down harmful substances in alcohol.
Key points about this process include:
- Enzyme efficiency: Individuals with a fully active ALDH2 enzyme can metabolize alcohol efficiently, reducing the likelihood of adverse reactions.
- Deficiency Effects: Those with an ALDH2 deficiency are more prone to experience symptoms like facial flushing, nausea, and rapid heartbeat after consuming alcohol.

Pre-existing Health Conditions
Certain medical conditions can exacerbate alcohol intolerance. These include:
- Asthma: People with asthma may experience worsening of their symptoms after consuming alcohol.
- Allergic Rhinitis: This condition can lead to an increased sensitivity to alcohol.
- Hodgkin’s Lymphoma: Patients with this type of cancer may develop alcohol intolerance.
- Enzyme Deficiency: Some people lack other enzymes necessary for alcohol metabolism, leading to similar symptoms.

Excessive Alcohol Consumption
Excessive alcohol consumption poses not only the risk of developing an alcohol allergy but also a myriad of other health complications. These complications can vary in severity, ranging from mild intolerances to more severe allergies and other adverse effects on the body. It is essential for individuals to be mindful of their alcohol intake and its potential impact on their health.
Practicing moderation and being aware of any adverse reactions to alcohol can help individuals make informed choices about their alcohol consumption and overall well-being.

Find Relief from Alcohol Allergy Symptoms with Trusted Care
Struggling with uncomfortable reactions to alcohol? You’re not alone—let’s work together to uncover the cause and find a solution.
Diagnosis & Treatment for an Alcohol Allergy
Your doctor will begin with a complete medical background assessment. It helps to understand the signs you show along with any possible triggers. This assessment includes questions on alcohol drinking habits. It also concerns the kinds of drinks consumed and if relatives had allergies as well as intolerances.
The physical exam is another crucial step in the diagnostic process. Your doctor will look for signs of allergic reactions, such as skin rashes or hives, and check for other symptoms like swelling or respiratory issues. In some cases, your doctor may observe how your body reacts to a controlled amount of alcohol to identify any immediate symptoms.
To pinpoint the exact cause of your symptoms, your doctor might recommend several diagnostic tests, including:
- Allergy tests: Skin prick tests or blood tests to check for specific allergic reactions.
- Elimination diet: Temporarily removing alcohol from your diet to see if symptoms improve.
- Challenge tests: Gradually reintroducing alcohol under medical supervision to monitor reactions.
These tests help determine whether your symptoms are due to an alcohol allergy, alcohol intolerance, or another underlying condition.
Living with Late-Onset Allergies
Living with a newly developed alcohol allergy calls for extra vigilance and preparation. It’s important to pay close attention to what you consume and have a plan in place for potential reactions. Key steps include:
- Informing family, friends, and dining establishments about your allergy to ensure your safety.
- Regular check-ups with an allergist to manage symptoms and prevent severe reactions.
Although many people are aware of alcohol intolerance—which can cause nausea, headaches, and facial flushing—it’s also possible to develop a full-blown alcohol allergy later in life. True alcohol allergies, while rare, may trigger severe reactions like trouble breathing, hives, or even anaphylaxis.
