7. Contact Dermatitis: The Skin’s Reaction to Irritants and Allergens
Red, Itchy Rash: The Primary Symptom of Contact Dermatitis
Contact dermatitis is a skin reaction caused by direct contact with an allergen or irritant, resulting in a red, itchy rash. It can be classified as either irritant contact dermatitis, caused by exposure to harsh substances, or allergic contact dermatitis, triggered by an allergic reaction to a specific substance.
Common Culprits: Identifying the Cause of Contact Dermatitis
Common irritants that can cause contact dermatitis include soaps, detergents, solvents, and abrasive materials. Allergens that can trigger allergic contact dermatitis include nickel, latex, fragrances, and certain preservatives in skincare products. Identifying the specific substance causing the reaction is key to managing and preventing contact dermatitis.
Treatment and Prevention: Relieving Symptoms and Avoiding Triggers
Treatment for contact dermatitis typically involves the use of topical corticosteroids to reduce inflammation and itching. Oral antihistamines or corticosteroids may be prescribed for more severe cases.
Preventing contact dermatitis involves identifying and avoiding the substances that cause the reaction. Patch testing may be performed by a healthcare professional to help determine the specific allergens or irritants responsible. (7)
