Erythritol and a severe allergic reaction in one woman

What it found

A 36-year-old woman had a severe allergic reaction after drinking a diet beverage containing erythritol.

Skin tests pointed to erythritol as the cause.

What they found

Studies in people

Severe allergic reaction

After drinking a peach diet beverage, the woman had trouble breathing and facial swelling. Her blood pressure dropped to 70/40 mmHg. Emergency medicines improved her symptoms.

Second reaction ten days later

Ten days later she drank a different diet beverage and developed hives and itching all over. She was treated again with allergy medicine and steroids.

Skin tests for erythritol

Skin prick tests were negative for peach but positive for both diet drinks. Tests using pure erythritol at 20 mg/mL and 200 mg/mL gave positive results. Three healthy adults tested negative.

Other reported cases

Earlier reports from Europe and Japan described allergic reactions to erythritol. A 61-year-old woman in Spain had a severe reaction after eating ice cream containing it. A woman in Japan developed hives after drinking canned tea with erythritol.

What the authors conclude

  • They diagnosed the woman with anaphylaxis caused by erythritol and told her to avoid it.
  • They prescribed her a self-injectable epinephrine pen for emergencies.
  • The authors advise doctors to consider food additives when investigating repeated allergic reactions.

How it was done

Erythritol is a low-calorie sweetener used in many foods and drinks, but few allergic reactions to it have been reported. The authors wanted to describe what they say is the first case of this kind in Korea.

The authors followed one 36-year-old woman who went to the emergency room twice after drinking diet beverages. They compared the drink ingredients and did skin prick tests on her and three healthy adults using erythritol solutions.

What it can’t tell you

  • This report describes only one person, so it cannot show how often erythritol causes allergic reactions.
  • The doctors did not do a feeding test to confirm the diagnosis because her first reaction was too severe.
  • A single case cannot prove that erythritol will cause this reaction in other people.
