Allergic dermatitis

Allergic Dermatitis is a common skin condition characterized by inflammation of the skin due to an allergic reaction. It is also known as contact dermatitis when the skin comes into direct contact with an allergen.

Causes

Allergic dermatitis is caused by an allergic reaction to a substance (allergen) that the body's immune system recognizes as foreign. Common allergens include nickel, rubber, cosmetics, fragrances, and poison ivy.

Symptoms

The primary symptom of allergic dermatitis is a red, itchy rash. Other symptoms may include blisters, hives, redness, and swelling. The rash typically appears where the skin came into contact with the allergen.

Diagnosis

Diagnosis of allergic dermatitis is typically made by a dermatologist based on the patient's symptoms and medical history. A patch test may be performed to identify the specific allergen causing the reaction.

Treatment

Treatment for allergic dermatitis primarily involves avoiding the allergen. Topical corticosteroids and antihistamines may be used to reduce inflammation and itching. In severe cases, oral corticosteroids may be prescribed.

Prevention

Prevention of allergic dermatitis involves avoiding known allergens. This may involve changes in personal care products, clothing, or work environment.
