Q

Contact dermatits

Management

A

Identify and Avoid the Trigger
The first step in treating contact dermatitis is to identify and avoid the substance that is causing the skin reaction.

Common triggers include:
* Soaps, detergents, or chemicals
* Latex
* Metals like nickel
* Certain plants like poison ivy
* Cosmetics or fragrances
* Avoiding further exposure to the trigger is crucial for clearing up the skin rash.

Manage Symptoms
To help relieve the symptoms of contact dermatitis, the treatment plan may include:
* Topical Corticosteroids: Applying a low-to-medium potency topical steroid cream or ointment can help reduce inflammation, itching, and swelling. Use as directed by your doctor.
* Oral Antihistamines: Taking an oral antihistamine like cetirizine or loratadine can help relieve itching.
* Cool Compresses: Applying cool, wet compresses to the affected area can soothe the skin and relieve discomfort.
* Oatmeal Baths: Soaking in an oatmeal bath can help relieve itching and dryness.
* Moisturizers: Using fragrance-free, hypoallergenic moisturizers can help hydrate the skin and prevent further irritation.

Manage Secondary Infections
If the skin becomes infected, your doctor may prescribe an antibiotic cream or oral antibiotic medication.
