What is eczema? Eczema is often called dermatitis or atopic dermatitis, but all of these terms mean the same thing. Eczema is an itchy skin condition which often occurs in families. The child or other family members may also have asthma or hay fever.

How do you recognise eczema?
  • The skin is generally dry.
  • The skin is itchy.
  • Some areas of the skin are inflamed – the skin is red and cracked, and may be oozing or weeping.
Certain areas of the body are particularly affected
  • Babies: the face.
  • Toddlers: the fronts of knees and ankles and the inside of wrists.
  • Older children and adults: the folds of elbows and knees.
  • In some people, the rash is all over the body.
What is eczema? Is it caused by an allergy?

It is often thought that eczema is due to an allergy to something, and that if this can be removed, the condition will be cured. In fact, very few people have eczema caused by an allergy. However, the same people who have eczema may also have allergies which give them different symptoms.

What is important in all people is that the skin is dry and easily irritated and is not a good barrier.

A person with a tendency to eczema is born with a dry, irritable skin. This type of skin needs special care to prevent eczema developing.

What can you do to deal with dryness?
  • Various moisturisers can be used. It should be applied all over, at least twice a day. Sometimes this irritates the skin, so you may need to try alternatives such as emulsifying ointment. Avoid creams containing urea, which will sting broken skin.
  • Bath oils eg. QV™ or Grahams Bath oil for kids.
What can irritate the skin?

Be aware of these things which can irritate the skin and try to avoid them:

  • Some materials, especially wool and acrylic (carpets, furniture, car seats and stroller covers as well as clothes). House dust mite in carpets can irritate some children.
  • Sand.
  • Perfumed and ‘medicated’ products.
  • Bubble baths.
  • Using soap.
  • Chlorine in pools.
  • Rapid changes of temperature and active exercise to the point of sweating.
  • Food allergies.
  • Dry air eg. heated rooms in winter, air conditioning in summer.

Not all these will irritate all children with eczema, but if you know what can cause trouble then you can avoid it.

Food allergy

If any foods seem to provoke a reaction, it may have to be taken out of the diet. It is best to check with a dietitian to make sure your child is not missing out on essential vitamins and minerals for growth.

What can be done if eczema develops?

If eczema develops, continue regular moisturising and avoid anything which irritates the skin.

Cortisone preparations will be prescribed to deal with the areas of eczema. These are safe as long as they are used as directed, and only used sparingly on areas of eczema. It is alright to apply them to broken skin. You can stop using them when the eczema settles down.

Most cortisone creams are best used twice a day on the affected areas. Some stronger preparations, which are rarely required, are used only once a day. It is important to follow the instructions carefully. In general, cortisone creams are better used in ointment bases (clear, greasy) than in cream bases (white) because the ointments are more moisturising. Some formulations are not suitable for the face or the nappy area.

If the eczema is very severe and is not responding to treatment at home, a period of intensive treatment in hospital with wet dressings will usually bring the condition under control. Cortisone tablets should not be used.

Is infection a risk with eczema?

Children with eczema often develop severe infections from the herpes simplex virus – the same virus that causes cold sores. People with cold sores should not be allowed to kiss your child. There is no special problem with other viruses and the usual childhood immunisations are safe.

Impetigo, a bacterial infection, can occur on top of the eczema. This will need antibiotic medicine. Do not use disinfectants – they will only irritate the skin.

  • Eczema cannot be cured but it can usually be controlled.
  • Avoid things which irritate the skin.
