Apply calamine lotion at the site of the lesions
and see if it helps. You could take some oral
antihistamine medications like cetrizine or loratadine. You need to maintain a good personal hygiene . Wear lose comfortable clothes. Wash all your linen and towels etc with a disinfectant solution.
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.
