Poison ivy treatments are usually limited to self-care methods. And the rash typically goes away on its own in two to three weeks.
If the rash is widespread or results in a large number of blisters, your doctor may prescribe an oral corticosteroid, such as prednisone. If a bacterial infection has developed at the rash site, your doctor may give you a prescription for an oral antibiotic.
