Steroids reduce inflammations anditching, but overuse can cause thinning of the skin.
    • Other creams containdrugssuch asProtopic(tacrolimus) that suppress the white blood cells and hence control skin reactions. Direct strong sunlight should be avoided when these products are being used.
    • Topical antibiotics may be prescribed to treat the secondary (superimposed) infection.
    • Regularly applying moisturizers that are free of chemicals, artificial colors, or fragrances will help soothe the skin, hydrate, repair, and soften it as well.

An antibacterial cream may be used if your skin has a bacterial infection, an open sore, or cracks. The doctor may recommend you take oral antibiotics for a short time to treat the infection.
  • Medication to reduce inflammation:Oral corticosteroids such asprednisonemay be prescribed in severe cases and cases in which there is no improvement with only topical medication. Steroids suppress the immune system and hence suppress inflammation and skin reactions.
  • Newer medications to treat severe eczema:Injectable medicines such as Dupixent (dupilumab) may be used in severe cases of eczema. These medications modify the immune system. They reduce inflammation and the signs and symptoms associated with eczema.

Other therapies

  • Phototherapy (light therapy):Light therapy can be used in cases when topical treatments don't help and in those who have frequent flare-ups. Light therapy involves exposing the skin to controlled amounts of natural sunlight or artificial ultraviolet A (UVA) and ultraviolet B (UVB).
