Contact dermatitis is a rash that is caused by a substance that is harmless to most people, such as nickel. A nickel allergy is one of the most common causes of contact dermatitis, according to the Mayo Clinic, but since nickel is used in the production of many items, it can be a challenge for someone who is allergic to avoid contact with it.
Items Containing Nickel
People with a nickel allergy need to be aware of items that might contain nickel and tell their doctor if they are exposed to it. Nickel is a metal frequently used in costume jewelry like earrings, necklaces, rings and bracelets. Clothing items, kitchen utensils, eyeglasses, pens, keys and many other products also can contain nickel. Considering all metal objects as potential problems is the safest bet.
Contact Dermatitis
People with contact dermatitis who have had a reaction to nickel might have redness, flaking, itching or a rash in the area of contact. For example, an earring containing nickel will affect the earlobe.
Identifying the Allergy
Visit a doctor for confirmation of a nickel allergy. A doctor might take a thorough history of exposure to certain substances and do a physical assessment. Some doctors might order a patch test, which will identify an allergic reaction to particular substances in a controlled test on the skin.
Treatment of Nickel Allergy
Creams or oral medications containing steroids might be used to treat dermatitis related to a nickel allergy. An antihistamine also might help with itching. Make sure a doctor confirms the diagnosis before taking any medication.
Prevention
Those with a nickel allergy should buy only jewelry that is hypoallergenic and make sure any piercings are done with items that do not contain nickel. Piercing guns might contain nickel and have the potential to become contaminated between customers. Other items like clothing, glasses or watches should be scrutinized prior to purchase or use.
