Treatment 

        • Treatments for atopic eczema can help to ease the symptoms. There’s no cure, but many children find their symptoms naturally improve as they get older. The main treatments for atopic eczema are:
        • emollients (moisturizers) – used every day to stop the skin from becoming dry topical corticosteroids – creams and ointments used to reduce swelling and redness during flare-ups Other treatments include:
        • topical pimecrolimus or tacrolimus for eczema in sensitive sites not responding to simpler treatment
        •  antihistamines for severe itching
        • bandages or special body suits to allow the body to heal underneath
        • Wet dressings

Wet dressings are an effective method to treat severe eczema and often reduce symptoms in several hours to days. While wet dressings may sound simple, a doctor or nurse may need to apply them. They’ll spread a corticosteroid cream on the affected area and cover it with a wet bandage. The wet bandages are then covered with dry bandages. Sometimes, a doctor can show you how to apply the wet dressings so you can put them on at home and use them as home remedies.

Oral Medications

Doctors may prescribe oral medications to people with eczema that isn’t in one specific area. Those who don’t respond to creams or ointments benefit from taking oral medications after medical advice. These work by slowing the immune system response, which can help to reduce the severity of eczema symptoms. Examples of oral medications for severe eczema symptoms include:

        • azathioprine (Imuran)
        • cyclosporine
        • methotrexate
        • mycophenolate mofetil
        • oral steroids, such as prednisolone or prednisone While these may help to reduce the incidence of eczema, they can come with some severe side effects.

Try to Reduce the Damage From Scratching

Eczema is often itchy, and it can be very tempting to scratch the affected areas of skin. But scratching usually damages the skin, which can itself cause more eczema to occur. The skin eventually thickens into leathery areas because of chronic scratching. Deep scratching also causes bleeding and increases the risk of your skin becoming infected or scarred. Try to reduce scratching whenever possible.

You could try gently rubbing your skin with your fingers instead. If your baby has atopic eczema, anti-scratch mittens may stop them from scratching their skin. Keep your nails short and clean to minimize damage to the skin from unintentional scratching.

Choosing emollient Several different emollients are available. Talk to a pharmacist for advice on which emollient to use. You may need to try a few to find one that works for you. You may also be advised to emollients, such as

        • an ointment for very dry skin
        • cream or lotion for less dry skin an emollient to use instead of soap
        • an emollient to use on your face and hands, and a different one to use on your body The difference between lotions, creams and ointments is the amount of oil they contain. Ointments contain the most oil so they can be quite greasy but are the most effective at keeping moisture in the skin.

Ointments contain the most oil so they can be quite greasy but are the most effective at keeping moisture in the skin. Lotions contain the least amount of oil so are not greasy but can be less effective. Creams are somewhere in between. If you have been using a particular emollient for some time, it may eventually become less effective or may start to irritate your skin. If this is the case, you may find another product that suits you better. You can speak to a pharmacist about other options. The best emollient is the one you feel happy using every day.

Preventing The following may help alleviate the symptoms and prevent future bouts (flares) of eczema:

Use moisturizer often (at least twice a day) even when symptoms. Applying moisturizer while the skin is still moist after a bath or shower to help lock in the moisture. Adding oil to bath water or making a bleach bath will also help to moisturize dry, eczema-prone skin. Discuss with a doctor or pharmacist the different types of moisturizers available. it may take some time and experimentation to find the best product for your child Wear pure cotton or cotton-mixture clothes instead of wool or synthetic not use soap, especially deodorant or antibacterial soaps.

Instead use a mild, non-fragranced liquid cleanser, emulsifying ointment, or water-dispersible cream showers or baths and use warm instead of hot water After bathing, gently pat rather than rub your skin dry using Avoid enzyme detergents and fabric softeners when washing clothes as these can imitate the skin Avoid foods that are known to provoke allergic reactions such as peanuts, eggs, seafood, milk soy and chocolate Direct use of antiseptics and solvents should be avoided Environmental factors, such as heat, sunlight, and cold can irritate the condition. If this is the case, avoid them as much as possible Use a humidifier in winter and summer Bandages can be used to stop scratching at night. Cotton mittens can also be helpful Fingernails should be kept short to decrease the damage caused by scratching.
