Allergy to metal

An allergic reaction to metal is an overreaction of the body's immune system to a substance (allergen) in a metal. An allergic reaction to metal can cause intense swelling, pain, and itching.

Nickel is the most common metal allergen. Jewelry that does not trigger an allergic reaction is made from:

• Stainless steel (grade-300).
• 14- or 18-karat gold.
• Niobium.
• Titanium.
• Platinum.
• Dense, nonporous plastic, such as monofilament nylon, acrylic, or Lucite.
