Alcohol intolerance requires careful management, with the primary strategy being avoidance of alcohol to prevent symptoms. You may be more likely to have alcohol intolerance symptoms reactions to alcohol if you have any of these factors. Aldehyde is toxic, and buildup is one of the key reasons people develop symptoms of a hangover.
What to expect from your doctor
In people with true alcohol allergy, as little as 1 milliliter (mL) of pure alcohol can trigger an allergic reaction. 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 might help reduce symptoms, such as itching or hives. Alcohol intolerance can cause immediate, uncomfortable reactions after you drink alcohol.
- Symptoms of alcohol intolerance can make a person feel uncomfortable.
- Over-the-counter (OTC) or prescribed medications might help reduce symptoms.
- The test will determine if one is allergic to some substance found in the alcohol, such as grains, which are commonly found in beer.
- Some medications can stop your ALDH enzymes from working as well as they normally do.
- One of the key enzymes involved in alcohol metabolism is aldehyde dehydrogenase 2 (ALDH2).

Symptoms of an Alcohol Allergy
Disulfiram, a medication recommended for alcohol abuse, can cause an immediate reaction when taken with alcohol. Symptoms may occur within seconds or minutes of alcohol exposure and could trigger after exposure to even tiny amounts of the allergen. Long COVID refers to persistent symptoms that occur more than three weeks after the initial COVID-19 infection. At the very least, you should limit alcohol as much as possible, especially if it’s making you unwell. Post-viral fatigue (PVF) is fatigue that first starts during a viral infection but persists after the virus has gone.
- A food allergy is an abnormal immune reaction to things we eat, while a food intolerance is an adverse reaction to food that does not involve the immune system.
- Grape allergies are rare, but they have been reported in some medical journals.
- The body produces antibodies, and when they encounter alcohol, they set off a systemic allergic reaction.
Sensitivity to Other Components
In a March 2021 blog post, neurologist Georgia Lea discussed the potential connection between long COVID, specifically the PVFS type, and alcohol intolerance. Several anecdotal reports suggest that alcohol intolerance may be linked to long COVID, specifically the post-viral fatigue syndrome (PVFS) type. Long COVID is a type of PVF that involves new or worsening COVID-19 symptoms months or years after the initial infection. It is unclear if distilled alcohol made from corn is safe for people with corn allergies. To date, there is little strong evidence of this, though distillation is likely to leave behind only negligible amounts of the proteins from the corn, if any.
Risk factors
- This is the same chemical involved in allergic reactions in the body.

- Alcohol withdrawal can begin within hours of ending a drinking session.
- Sulfites interact with stomach acid to release an irritant gas called sulfur dioxide, which can cause airway irritation in susceptible individuals.
