Mandarin Oranges and Allergies

An allergy to mandarin organs is considered uncommon. If you are allergic to mandarin oranges you suffer from a citrus allergy and may have similar allergic reactions to other citrus fruit, such as lime or grapefruit, according to Family Allergy and Asthma Care of Montana 1. If you believe you are experiencing an allergic reaction after touching or eating mandarin oranges, you should see a doctor immediately. While most symptoms of allergy to mandarin oranges are mild and harmless, there remains the risk of anaphylactic shock.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.


The proteins from the mandarin orange cause the immune system to respond by creating a defense system. The immune system mistakes the mandarin orange proteins as a harmful substance and develops antibodies and histamine to fight them off. This chemical reaction in the body leads to common food allergy symptoms 4.

Contact Dermatitis Consideration

Contact dermatitis is and allergic reaction of the skin that is common in people with a citrus allergy. It occurs most often when certain citrus substances come in direct contact with the skin. According to the Merck Manuals, the skin becomes inflamed and forms small blisters that are extremely itchy and can burn. If exposure to mandarin oranges causes contact dermatitis, wash the affected area to get rid of any residue, use a cold compress to reduce the itch and take an antihistamine to relieve inflammation.


The most effective treatment for an allergy to mandarin oranges -- or any food -- is to avoid exposure to them, according to FARE 4. Avoid all citrus fruits and to read the labels of any food or beverage before consuming. Other treatments include taking an oral antihistamine to alleviate mild symptoms, such as sneezing or itchy eyes. An injection of epinephrine may be required if symptoms of anaphylactic shock are present.


Although rare, an allergy to mandarin oranges can lead to a severe allergic reaction. Anaphylaxis is a condition where excessive amount of histamine are produced in the body, sending the body into a state of shock. Get immediate medical attention if you experience symptoms such as inability to breathe, hives or a drop in blood pressure.
