Thank you for your query on Healthcare Magic.
The main concept of treatment in eczema
is to maintain hydration of the skin, to decrease itching and scratching, to avoid exposure to allergens, to prevent skin infections , and to decrease the inflammation and allergic reaction
You can apply lactocalamine for itching.
If the itching is severe you can give an oral antihistamine in prescribed dosage for 2 to 3 days.
I advise you to follow your Pediatrician
advise and be in regular follow up.
Hope I have answered your query.
