Causes and Treatments of Allergic Dermatitis – an Allergic Rash

Allergic Dermatitis, or an allergic rash, is skin inflammation resulting from contact with some form of allergen. The rash itself is actually the skin’s natural defensive response to this allergen and, unfortunately, there is no one-single cause of allergic dermatitis in people.

Though there isn’t a single cause, there are common symptoms of an allergic rash. The most common is the appearance of dry, scaling, itchy skin where contact with the allergen occurred. Common places to find red patches on the skin include the neck and wrists (caused by allergic reactions to either jewelry or cosmetics).

Other causes of allergic rashes include:

  • Colognes/perfumes
  • Certain fabrics
  • Shampoos
  • Animals
  • Fragrances from laundry detergents

No one person is the same, thus the causes of an allergic rash can and will vary greatly.

How to Treat an Allergic Rash

The first step in treating an allergic rash is to remove the item (or allergen) that caused the rash to begin with. This might include some investigative work on your part, to learn what exactly triggered the rash. Once the trigger is determined (usual offenders include: certain metals, detergents, chemicals, personal products, or pets), it’s important to remove the allergen from your environment. 

Once removed, topical creams or oral steroids can be used to treat allergic dermatitis.  Typically an allergic dermatitis physician or dermatologist, will be able to determine the best treatment for an allergic rash.

Are Allergic Rashes Dangerous?

In most cases, allergic dermatitis is not dangerous, and is not cause for major concern. However, this does not mean that you should not see a rash specialist if you suffer from unexplained bumps, scaling, or bleeding. These symptoms could, in fact, indicate a more serious skin condition. It is particularly important to see a dermatologist if the irritation is persistent or reoccurring, so that other skin conditions can be diagnosed and eliminated.

Other causes of skin rashes

Causes of a skin rash can go beyond an allergen. Other potential causes of a skin rash include psoriasis, eczema, bacterial and fungal infections, and poison oak, ivy, or sumac. Treatments for these kinds of rashes will vary. Simply avoiding rash-causing irritants (such as poison oak) will eliminate that form of skin rash. Viral, fungal, and bacterial infections, however, can be treated through a topical cream or oral medication.

In order to treat chronic skin conditions, such as psoriasis or eczema, it’s important to take part in an ongoing skincare treatment plan in order to keep symptoms under control.
