Red Dye Allergy Information

Some people experience an intolerance or allergic reaction to red dyes used in food, drugs and cosmetics. Reactions range from mild to severe. Red dye is made from either cochineal or carmine additives and has been recognized as a known allergen by the FDA.

Composition

• The additives in red dye come from dried insects either from the cochineal bug and the cochineal beetle. These insects most commonly come from South and Central America.

Intestinal Reaction

• Reactions to ingested red dye vary from patient to patient and may include gastrointestinal symptoms including cramps, bloating, gas and diarrhea.

Skin Reaction

• Reactions to red dye either ingested or applied topically (in cosmetics) may include skin reactions such as hives, rashes, swelling, redness and itching.

Other Reactions

• Other reactions can range from mild symptoms such as sneezing, watery eyes and flu-like symptoms. More serious reactions may include anaphylaxis, a very severe allergic reaction, or seizure.

Treatment

• Intestinal problems pass as the additive passes from the system. The cold or flu-like symptoms can be treated with antihistamines. Skin reactions can be treated with topical creams. Severe reactions should be monitored and patients should seek medical attention.
