PP, unless your instructions are different to mine, the prednisone is taken up until 12 weeks. But the up until 20 weeks is probably coming from the fact that you can't stop it suddenly. You need to wean off it very slowly as coming off too fast can send the body into an adrenal crisis. For most people it's not too bad, for me, getting off it completely is hell - it's a drug that I appear to be very sensitive to.

If you're not comfortable with anything, email Dr S again. I think the most important part of all this is that you are comfortable with your treatment.
