Symptoms

Signs and symptoms of alcohol intolerance — or of a reaction to ingredients in an alcoholic beverage — can include:

• Facial redness (flushing)
• Red, itchy skin bumps (hives)
• Worsening of pre-existing asthma
• Runny or stuffy nose
• Low blood pressure
• Nausea and vomiting
• Diarrhea

When to see a doctor

Having a mild intolerance to alcohol or something else in alcoholic beverages might not require a trip to a doctor. Simply avoid alcohol, limit how much you drink or avoid certain types of alcoholic beverages.

However, if you have a serious reaction or severe pain, see your doctor. Also, if your symptoms seem to be linked to an allergy or a medication you're taking, see your doctor.
