20 mg is still a relatively low dose. If you have a lot of inflammation going on it might take a few more days for the prednisone to kick in at that dose. When I have done a quick burst to try to bring a flare under control I have been on as much as 60mg for the first few days. You will probably have fewer side effects this way, but it will take a few more days before it gets things under control. Do you remember what you were on before when you have done tapers?

Managing with strict low residue diet, keeping symptoms to a minimum. All test show small amount of ulceration, still have occasional blockages. But still have a great time with my 2 daughters and husband!
