Rhus dermatitis can be caused by coming into contact with the oils of certain plants like poison ivy, poison oak and poison sumac. It appears as a hypersensitivity reaction that includes itching, inflammation, oozing and sometimes a burning sensation.


Dr. Harlan typically treats his adult patients for rhus dermatitis by having them apply SmartLotion® 2-4x per day for up to 2 weeks.

He says that it is important to avoid re-exposure and heavy exercise.

Topical or oral antihistamines like Benadryl can also be used to help relieve itching.
