Often, doctors will recommend immunosuppressant drugs in conjunction with or intstead of corticosteroids (such as Prednisone). Methotrexate, Azathioprine, and Cytoxin are the most commonly prescribed immunosuppressants. Perhaps you can ask your doctor about taking one of these with a lower dose of Prednisone or in place of Prednisone.
But, PLEASE know that ALL of these drugs come with their own side effects. So, taking one to avoid side effects usually does not pan out as well as we hope. So, you then have to decide which side effects you are more able to endure.
I wish you the very best.
Peace and Blessings
