Rashes that result from metal allergies often clear up by themselves once the skin is free of contact with the offending metal allergen. In some cases, a physician may prescribe a corticosteroid cream to clear up the rash and reduce itchiness. 

Skin that is damaged by contact with metal must be carefully cared for until it heals. Moisturizers can keep the skin from peeling and cracking. Excessive scratching of skin with fingernails presents the risk of bacterial infection. If this occurs, antibiotics may need to be prescribed to cure the condition. 

Desensitization techniques, such as allergy shots, are not effective for metal allergies. The only truly effective way to prevent metal allergies is to eliminate exposure to the allergen that triggers symptoms. This can be exceedingly difficult with metal allergies, because allergens such as nickel are present in so many products. However, brief contact with metals usually will not cause a reaction, even in allergic individuals. The key is to avoid regular, sustained skin contact with the allergen.

Steps that can be taken to reduce the likelihood of symptoms include:

• Wear nickel-free, plastic jewelry, stainless–steel, platinum, titanium or 18 karat gold.
  
  
• Try to use substitutes for metal, such as items made of wood, plastic, paper or fabric. Even if the object itself is metal, try to be sure that the portion that comes into contact with the skin – such as a handle – is not.
  
  
• Those prone to “shoe dermatitis” should change shoes and socks throughout the day, especially if their feet perspire excessively.
  
  
• Wear protective clothing to avoid skin contact with the allergen at home and in the workplace. However, do not use gloves for wet work unless they are 100 percent waterproof, as wet skin increases the penetration ability of metals. Also, some people may need to avoid latex gloves because latex is also a common allergen.
  
  
• Coat metal items such as keys or buckles with several layers of clear nail polish and cover them with tape. This provides a barrier to keep metals from direct contact with the skin.
  
  
• Check ingredients carefully in all products that may be potential sources of metal allergies. Do not purchase products that contain allergens likely to trigger a reaction.
