Contact dermatitis is a term for a skin reaction ensuing from exposure to allergens (allergic contact dermatitis) or irritants (irritant contact dermatitis). Reactions may differ in the similar person over time. A history of any form of allergies enlarges the risk for this condition.
Contact dermatitis outcomes in large, burning, and itchy rashes, and these can take anywhere from several days to weeks to heal. Chronic contact dermatitis can extend when the deletion of the offending agent no longer gives expected relief.
Some products such as sulfa ointments, several perfumes, coal tar products, induce a reaction simply when they contact the skin and are exposed to sunlight (photosensitivity).
Symptoms generally emerge on the area of the skin that has been exposed. A skin "patch" test is used to conclude the most probable substances that are causing you to have an allergic response on your skin.
Treatment of Contact Dermatitis
- Antibiotics are suggested for bacterial skin infections.
- In severe cases, systemic corticosteroids may be required to lessen irritation.
- Wet dressings and calming anti-itch (antipruritic) or drying lotions may be suggested to lessen other symptoms.
- Oral antihistamines for instance diphenhydramine (Benadryl, Ben-Allergin) can as well alleviate itching.
