Final answer:
Contact dermatitis can be treated with antihistamines, anti-inflammatory drugs, and analgesics, and by preventing further exposure to the allergen.
Step-by-step explanation:
Treatment of Contact Dermatitis
Aside from removing the source of the allergen, contact dermatitis is typically treated through several methods.
Use of antihistamines can help alleviate itching and swelling associated with allergic reactions.
Furthermore, anti-inflammatory drugs, such as corticosteroids, can reduce inflammation and are often applied topically to the affected area. When pain is a symptom, analgesics might be recommended to provide relief.
It is also crucial to avoid further exposure to the antigen to prevent recurrence of the hypersensitivity reaction.
Contact dermatitis is a common type of type IV hypersensitivity, which is a delayed allergic reaction.
This type of hypersensitivity reaction can also be seen in reactions like tuberculin skin reactions, as well as autoimmune diseases including diabetes mellitus type I, multiple sclerosis, and rheumatoid arthritis.
