DESCRIPTION
Atopic eczema (atopic dermatitis) can affect people of all
ages but is most commonly seen in children. In most cases children
grow-out of Atopic eczema as they get older, however it is not
possible to tell when or if this will happen in individual cases.
Approximately fifty per cent of children will no longer be troubled
by eczema by two years of age and eighty five per cent by five
years of age.

Approximately fifty per cent of children will no longer be troubled

Some people are only mildly affected and have small areas of
dry skin, which are occasionally itchy. In more severe cases the
skin may become cracked which causes soreness and bleeding

CAUSE
The exact cause of eczema is not known. It is known that a
history of eczema, asthma or hay fever in the family does increase
a person’s risk of developing one of these conditions.

TRIGGER FACTORS
If you and your GP are able to establish which factors trigger
eczema flare-ups, you can try to avoid contact with them. It is
important to be aware of the following 3 factors and remove them
from your environment:
eczema flare-ups, you can try to avoid contact with them. It is
important to be aware of the following 3 factors and remove them
from your environment:
Heat. The skin of a person with eczema is very hot, and heat
increases the itch. Avoid hot baths and long car trips. Dress in a
couple of thin layers rather than a thick layer of clothing. A
single layer can be removed in warm weather or if you are
participating in physical activity. Avoid heavy bed-covers. Soft
cotton or silk sheets and one thin cotton blanket are appropriate
bed linen. Children with eczema are prone to frequent waking and
scratching through the night. Wet dressings improve the sleep
pattern of children with eczema, by keeping them cool and reducing
the itch.

Dryness. The skin should be moisturised many times a day to help
with this dryness. There are many things that can dry the skin like
water, air-blowing heaters, cleaning agents, soap, swimming and dry
winds. Your skin will be dryer in the winter as the humidity is
lower and heaters are used more.

Irritation. Clothing can worsen eczema especially when it has a
prickly feeling. Large fibres, especially seams, wool, stitching,
tags, frills and lace edges will make you feel itchier. Small
cotton or silk fibres are the fabrics of choice for clothing or bed
linen.

or many areas on the face and body and it can be mild, moderate or
severe.
or many areas on the face and body and it can be mild, moderate or

Atopic eczema can cause your skin to become:
- dry,
- itchy,
- red,
- broken,
- thickened and cracked.
During a flare-up, your skin may be extremely itchy, red, hot,
dry and scaly, wet, weeping and swollen, and infected with bacteria
(usually staphylococcus).

(usually staphylococcus).
Children
When the rash begins in the first few months of life it
normally affects the face. The cheeks and chin become red, dry, hot
and itchy. This is made worse by dribbling, hands touching the face
and mouth and saliva irritating the skin. At this age eczema may
also affect the trunk and limbs, but less severely. As the child
develops, the eczema is less likely to affect the face and more
likely to be present on the limbs and trunk. The nappy area is not
usually affected. When the child becomes school-aged the eczema
tends to affect the hot areas of the body, such as the skin creases
of the neck, elbows, knees and buttocks.

TREATMENT OPTIONS
As with all conditions your Doctor should be consulted for the
diagnosis and treatment of this condition. People with severe
eczema often find that it has a significant impact on their daily
lives. Unfortunately there is no cure for eczema, although there
are many ways to keep it under control. Atopic eczema can cause a
child to scratch their skin because of the itch. These areas may
become infected with bacteria and this can worsen the eczema. If
there is an infection, your child may need a course of oral
antibiotics. In some severe cases of Atopic eczema, your GP may
refer you to a Dermatologist (a specialist in treating skin
conditions) for assessment and treatment.

Emollients are substances that help to soften and smooth your
skin in order to keep it supple and moist. They are also used
instead of soap. This is one of the most important forms of Atopic
eczema management. It is important to keep the skin moisturised to
prevent dryness, cracking and further irritation. Your GP will
recommend the most suitable types of emollient for your individual
needs.

A topical corticosteroid (one that is applied directly to your
skin) may be prescribed by your GP in more severe cases of Atopic
eczema and for flare-ups of the condition. Corticosteroids work by
quickly reducing inflammation. When used correctly, corticosteroids
are safe and effective.

Antihistamines help to reduce the symptoms caused by allergies e.g
sneezing, watery eyes and itching. Antihistamines can either be
sedating or non-sedating. Sedating anti-histamines can make people
feel drowsy. They are normally prescribed during an eczema flare-up
to help ease itchiness at night, helping you or your child to get a
good night’s sleep. Sedating antihistamines are prescribed on a
short-term basis, usually for a maximum of two weeks at a time.
Sedating antihistamines should NOT be given to children under two
years of age.

Wet dressings are important for the effective management of eczema.
Wet dressings are essential when your child is itchy and hot and if
they are waking from the itch. Your child may need a wet dressing
if they itch and scratch during the night, if there is blood in the
sheets in the morning, and if the eczema is still present despite
treatment with topical corticosteroids, moisturisers and bath oils.
See the Healthpoint topic Wet dressings for more information.

DIET HINTS
If you or your child have Atopic eczema, it is advisable to
consult your GP before making any significant dietary changes. Your
GP may refer you to a Dietician for specialist advice. Some foods,
such as milk, eggs and nuts, have been shown to trigger eczema
symptoms. If you are breastfeeding a baby who has atopic eczema, it
is advisable to seek medical advice before making any changes to
your regular diet.

PHARMACIST’S ADVICE
Ask your Pharmacist for advice.
- Avoid using soap where possible and use emollients to cleanse
and combat dry skin. Ask your Pharmacist for advice. - Normal shampoos can be replaced with a soap-free cleanser.
- Keep the skin cool and well moisturised to help reduce severity
of symptoms. - A warm (not hot) bath containing lubricating oils may help to
relieve dry skin. - Avoid bathing or showering in very hot water as heat can
aggravate eczema. - Wet dressings can provide relief to itching, dry skin. Dip a
non-irritating cloth into cold water, wring out excess fluid and
apply to the itchy area for 15-20 minutes. The cloth may be
rewetted as often as needed. Ask your Pharmacist to recommend a
suitable cloth - Avoid irritants such as woollen clothing, chemicals,
detergents, cosmetics etc. If the diet is inadequate, some
dietary supplements might be considered. Ask your Pharmacist for
advice on dosages and interactions.
