General Description


Prednisone and Prednisolone are steroids that reduce inflammation and suppress the immune system. They can be beneficial in treating many diseases and disorders, but should be given at low doses for short period of time to reduce any adverse effects. They may also be used to assist in treatment of Addison’s disease, cancers, shock, and nervous system disorders.

How It Works


Prednisolone is a corticosteroid known as a glucocorticoid. Corticosteroids are meant to resemble a naturally occurring hormone produced in the adrenal cortex, cortisol. Corticosteroids act on the immune system by blocking the production of substances that trigger inflammatory and immune responses.


In your pet’s liver, prednisone is converted to prednisolone. Pets with severe liver problems are not able to make this conversion, and many believe that these pets should only be given prednisolone.


Storage Information


Store in a tightly sealed container at room temperature.
