How can i get rid of poison oak or poison ivy?

Topica/oral steroids: Poison ivy and poison oak are types of allergic contact dermatitis, which usually will resolve spontaneously within 2 weeks. For milder cases, use of a topical corticosteroid is effective. More severe cases, especially when the disease affects that face, often require oral corticosteroids, such as prednisone.

Corticosteroids : If the affected skin is under several square inches in area then a topical corticosteroid cream or ointment can be used. If the area is larger then an oral corticosteroi e.g. Prednisone, will probably be required.
