Overview
Diagnosis
Nickel allergy is usually diagnosed based on symptoms and a history of exposure to nickel or other metals. A healthcare professional may refer you to an allergist or dermatologist for further evaluation.
-
Patch testing: Small amounts of common allergens, including nickel, are applied to the skin and covered with patches for two days. Irritation under the patch indicates an allergy. Patch tests are safe even for people with severe allergies.
Treatment
There is no cure for nickel allergy, so avoiding contact with nickel is the primary approach.
-
Medications:
-
Corticosteroid creams applied for 2 to 4 weeks reduce irritation. Prolonged use can thin the skin.
-
Nonsteroidal creams like tacrolimus, ruxolitinib, or crisaborole can be alternatives. Tacrolimus may cause temporary burning or stinging.
-
Oral corticosteroids such as prednisone are used for severe or widespread reactions but only for short durations.
-
Oral antihistamines may relieve itching.
-
-
Phototherapy: Exposure to controlled amounts of ultraviolet light may be considered for cases not responding to topical or oral treatments.
-
Self-care:
-
Regular moisturizing to soothe and protect the skin.
-
Wet compresses with aluminum acetate or colloidal oatmeal solution for rough or itchy areas.
-
Preparing for your appointment
Before seeing your healthcare professional, prepare by:
-
Writing down symptom details, timing, and patterns.
-
Listing metal products that contact your skin.
-
Listing medications, vitamins, and supplements, including doses and reasons.
-
Preparing questions for your healthcare professional, such as the likely cause of the rash, alternative causes, expected side effects, and options for nonprescription treatments.
Your healthcare professional will likely ask about:
-
Symptom onset and location of the rash.
-
Other associated symptoms.
-
Jewelry use and occupational exposures.
-
Changes in symptoms over time.
-
Home treatments tried and their effects.
-
Factors that worsen your symptoms.
