Anti-itch drugs, often antihistamine, may reduce the itch during a flare up
of eczema, and the reduced scratching
in turn reduces damage and irritation to the skin.
They do not cure eczema, but are highly effective in controlling or suppressing symptoms in most cases.
For mild-moderate eczema a weak steroid may be used (e.g. hydrocortisone or desonide), whilst more severe cases require a higher-potency steroid (e.g. clobetasol propionate, fluocinonide).
