Iatrogenic and Pseudo-Cushings
A very small percentage of Cushings cases result from medical treatments for other conditions, such as the use of prednisone or other corticosteroid medications to control allergies, arthritis, or autoimmune conditions. This is called iatrogenic (doctor-caused) Cushings. In these cases, the Cushings is treated by gradual discontinuation of the corticosteroid drugs (if the drugs are withdrawn too quickly, an Addisonian crisis can result). Patients can take as long as three months to recover after corticosteroid drugs are stopped.
