Ammonia Dermatitis/ Diaper Rash

Ammonia dermatitis is simply another name for diaper rash. This term can describe a number of causes for skin irritation in the region covered by a diaper. The most common reason for diaper or nappy rash is down to contact irritation, where it can affect anyone who wears a diaper (for example toddlers or incontinent adults).

The Cause of Diaper Rash

Diaper rash is most commonly caused by contact, meaning that folded areas of the skin remain unaffected. The second most common cause is skin infection, where bacteria can overwhelm the natural defence mechanisms of the skin. The type of infections often experienced are termed impetigo – where tiny blisters develop and rupture.

Diaper rash is not normally caused by an allergic reaction. However, some may be allergic to fragrances and other materials used in either diapers or wipes. Skin patch testing can determine whether an allergen is indeed the cause of diaper rash.

Treatment for Diaper Rash

Once diaper rash has been noticed then avoidance is the best treatment. This means avoiding contact in the areas that have been infected. Changing the diaper more frequently will leave the skin less exposed to urine or stool exposure and will help to manage the rash, or prevent it in many cases.

When a rash has developed it should be cleaned with water and soft cloths, rather than disposable wipes which could irritate the area. It may also help to apply petroleum jelly or other products to reduce friction.

Leaving the skin exposed to open-air will help the diaper rash clear up quicker. Sitting in a warm water bath for around 15 to 20 minutes usually helps relieve the symptoms. Should these methods not work then it may be possible for a secondary yeast infection to develop, in which case you should visit a paediatrician.
