Alcohol Allergies: Symptoms, Signs, and Treatment for Reactions

However, the best treatment is the avoidance of histamine in the foods we consume, including alcohol. Even so, many people with celiac disease or gluten sensitivity report reactions to distilled spirits made from gluten grains. If this is you, you can consider drinking potato-based or grape-based vodka. There are also certain whiskeys made from sorghum (a gluten-free grain).

Immediate Symptoms

• Something in the alcohol, such as hops or grapes, causes most alcohol allergies rather than the alcohol itself.
• This is likely due to “practice” as they continue to use alcohol regularly.
• A 2023 study found that individuals with CFS are more likely to experience alcohol intolerance.
• Unlike the immediate symptoms, these symptoms may or may not happen when alcohol is used.

It helps to read the product label, although many ingredients used in the fermentation or distillation process may not be included. Allergies to brewer’s yeast and other yeasts have been well-documented in the medical literature. Yeast is used in all fermented alcoholic beverages, including beer, wine, hard cider, and sake. Malted barley is used to make beer and some other alcoholic drinks, such as whiskey, and some alcoholic drinks contain wheat.

• Continuing to drink alcohol while knowing you are intolerant (or allergic) can also have severe health consequences.
• When it comes to an intolerance, the body simply isn’t up to the task of breaking it down.
• Several anecdotal reports suggest that alcohol intolerance may be linked to long COVID, specifically the post-viral fatigue syndrome (PVFS) type.
• If your body doesn’t produce enough active DAO, you may react to histamine in foods and beverages.

What to expect from your doctor

If someone has a true allergy to alcohol, they should avoid the substance entirely. People with alcohol intolerance could still consume alcohol, although they will likely experience side effects. An alcohol allergy is a rare toxic reaction to alcohol that can be fatal in rare cases. Often, what people consider to be an alcohol allergy is, in fact, alcohol intolerance.

Diagnosing Alcohol Intolerance: Tests and Procedures

• For example, aged cheese, smoked meats, sauerkraut, wine, and beer tend to be high in histamines.
• Certain factors can increase the risk of developing an allergy to alcohol later in life.
• When you have an allergic reaction to alcohol, your immune system is overreacting to an ingredient in the drink.
• Some people may even have reactions to grapes or corn used to make wine and distilled liquors.
• Alcohol intolerance can lead to a range of immediate reactions, but it also presents significant long-term health risks.

Red wine contains high levels of histamine and may cause headaches, congestion, and itching in people with histamine intolerance. Many foods, including red wine and aged cheese, are high in histamine. This is the same chemical involved in allergic reactions in the body. Your doctor can give you medications to lessen the symptoms of alcohol intolerance, such as anti-inflammatory medicines for pain. However, many medicines are not supposed to be used with alcohol. Additionally, medications only help mask symptoms and do not help with the underlying problem.

Alcohol intolerance vs. allergy

• True alcohol allergy is thought to be rare, while alcohol intolerance is more common.
• Alcohol allergy and alcohol intolerance are distinct conditions with different underlying mechanisms.
• If left untreated, an allergic reaction can quickly become worse.
• However, people with alcohol intolerance often have a genetic variant that causes ALDH to work less effectively.
• The body produces antibodies, and when they encounter alcohol, they set off a systemic allergic reaction.

An alcohol intolerance occurs when someone’s body lacks the enzymes to suitably digest alcohol. As a result, a person may experience facial flushing and skin and digestive issues. Diagnosis typically involves a thorough review of medical history, physical examination, and laboratory testing to rule out other conditions like alcohol allergy or histamine intolerance.

Medications You Shouldn’t Mix With Alcohol: Azithromycin, Sudafed, Mucinex, and More

If you might have an intolerance instead of an allergy, you could see a gastroenterologist, a healthcare provider specializing in digestive issues. Alcohol intolerance is most common in people of Asian descent because they are more likely to have a genetic mutation that prevents enzymes from breaking down alcohol. Food intolerance occurs when your digestive alcohol intolerance symptoms system has a hard time with a particular food. With intolerance or sensitivity, your digestive system gets irritated by certain foods or has trouble digesting them. If you have an alcohol allergy, you can develop an itchy rash, swelling, nausea, and even breathing trouble. If they don’t, you may experience a so-called “red wine headache” and other symptoms.
