Prednisone is considered an important drug in cases where anti-inflammatory activity or suppression of the body's immune system is desirable. The mechanism by which prednisone exerts it's anti-inflammatory effect is not clear but it is thought that many factors are involved. Its ability to affect the body's immune system is also due to several factors that take place at the cellular level.


High dose or long term therapy must be withdrawn gradually (tapered).
Growth may be suppressed in children receiving long-term daily therapy.
While taking prednisone, signs of infection can be masked and new infections may appear.
Diabetics may need to increase their dose of insulin or oral diabetes medications.
Prednisone can cause mental or mood disturbances (e.g. depression).
