Allergic Contact Dermatitis (rashes)
Allergic Contact Dermatitis is caused by a reaction to substances called allergens that come into contact with your skin (for example, poison ivy). In susceptible people, these contact allergens can cause itching, redness, and blisters.
Mild rashes that occur from allergic contact dermatitis usually respond to topical steroid creams and/or oral antihistamines that your dermatologist will prescribe.
Severe rashes may need to be treated with systemic methods such as oral and injectable corticosterioids, antibiotics, or other anti-inflammatory and immunologic agents.
