I've never seen anyone start at 10 mg and work their way up. Physicians usually start someone out on 40 to 60 mg and they reduce the amount of Prednisone by 5 to 10 mg per week. Quiting prednisone immediately can cause severe side effects.
If Prednisone is going to work at all, you should see results almost immediately. Prednisone no longer works for me.
